Serum triglyceride: a possible risk factor for ruptured abdominal aortic aneurysm. (1/4426)

BACKGROUND: We aimed to determine the relationship between ruptured abdominal aortic aneurysm (AAA) and serum concentrations of lipids and apolipoproteins. METHODS: A cohort of 21 520 men, aged 35-64 years, was recruited from men attending the British United Provident Association (BUPA) clinic in London for a routine medical examination in 1975-1982. Smoking habits, weight, height and blood pressure were recorded at entry. Lipids and apolipoproteins were measured in stored serum samples from the 30 men who subsequently died of ruptured AAA and 150 matched controls. RESULTS: Triglyceride was strongly related to risk of ruptured AAA. In univariate analyses the risk in men on the 90th centile of the distribution relative to the risk in men on the 10th (RO10-90) was 12 (95% confidence interval [CI] : 3.8-37) for triglyceride, 5.5 (95% CI: 1.8-17) for apolipoprotein B (apoB) (the protein component of low density lipoprotein [LDL]), 0.15 (95% CI : 0.04-0.56) for apo A1 (the protein component of high density lipoprotein [HDL]), 3.7 (95% CI: 1.4-9.4) for body mass index and 3.0 (95% CI: 1.1-8.5) for systolic blood pressure. Lipoprotein (a) (Lp(a)) was not a significant risk factor (RO10-90 = 1.6, 95% CI: 0.6-3.0). In multivariate analysis triglyceride retained its strong association. CONCLUSION: Triglyceride appears to be a strong risk factor for ruptured AAA, although further studies are required to clarify this. If this and other associations are cause and effect, then changing the distribution of risk factors in the population (by many people stopping smoking and adopting a lower saturated fat diet and by lowering blood pressure) could achieve an important reduction in mortality from ruptured AAA.  (+info)

The impact of an amino acid-based peritoneal dialysis fluid on plasma total homocysteine levels, lipid profile and body fat mass. (2/4426)

BACKGROUND: The caloric load from glucose-based peritoneal dialysis (PD) fluids contributes to hypertriglyceridaemia, adiposity and, as result of anorexia, protein malnutrition in PD patients. It has been suggested that replacement of a glucose-based by an amino acids-based PD fluid (AA-PDF) for one exchange per day might improve the nutritional status and lipid profile. Due to the uptake of methionine from the dialysate, however, exposure to AA-PDF might aggravate hyperhomocysteinaemia, a frequently occurring risk factor for atherosclerosis in uraemic patients. METHODS: We studied the impact of a once daily exchange with 1.1% AA-PDF instead of glucose-based PD fluid for 2 months on plasma methionine and total homocysteine (tHcy) levels, lipid profile, butyrylcholinesterase (BChE) and body fat mass of seven stable PD patients. Results are expressed as mean+/-SEM. RESULTS: Methionine levels did not increase significantly during therapy, but tHcy levels increased substantially from 60+/-12 to 84+/-19 micromol/l after 1 month (P=0.039), and to 85+/-22 micromol/l after 2 months of AA-PDF treatment. Serum triglyceride concentration decreased from 3.0+/-0.4 mmol/l at entry to 2.6+/-0.5 mmol/l (at 1 month, P=0.041 vs baseline). Serum BChE also decreased from 6.9+/-0.4 U/ml at entry to 6.3+/-0.4 U/ml after 2 months (P=0.014). Total cholesterol concentration and cholesterol fractions did not change. The reduced exposure to glucose-based PD fluid for 2 months resulted in a 0.5 kg reduction in fat mass which was due mainly to a reduction in fat mass of the trunk region (0.3 kg, P=0.031). CONCLUSIONS: It is concluded that methionine-containing AA-PDF induces an increase in the plasma tHcy level. This might, potentially, offset the beneficial effects of an improved serum lipid profile and reduced fat mass on the risk of cardiovascular disease in PD patients. Lowering the methionine content of the fluid, therefore, may be required to overcome this adverse effect.  (+info)

Socioeconomic status and determinants of hemostatic function in healthy women. (3/4426)

Hemostatic factors are reported to be associated with coronary heart disease (CHD). Socioeconomic status (SES) is 1 of the determinants of the hemostatic profile, but the factors underlying this association are not well known. Our aim was to examine determinants of the socioeconomic differences in hemostatic profile. Between 1991 and 1994, we studied 300 healthy women, aged 30 to 65 years, who were representative of women living in the greater Stockholm area. Fibrinogen, factor VII mass concentration (FVII:Ag), activated factor VII (FVIIa), von Willebrand factor (vWF), and plasminogen activator inhibitor-1 (PAI-1) were measured. Educational attainment was used as a measure of SES. Low educational level and an unfavorable hemostatic profile were both associated with older age, unhealthful life style, psychosocial stress, atherogenic biochemical factors, and hypertension. Levels of hemostatic factors increased with lower educational attainment. Independently of age, the differences between the lowest (mandatory) and highest (college/university) education in FVII:Ag levels were 41 microg/L (95% confidence interval [CI], 15 to 66 microg/L, P=0.001), 0.26 g/L (95% CI, 0.10 to 0.42 g/L, P=0.001) in fibrinogen levels, and 0.11 U/mL (95% CI, 0.09 to 0.12 U/mL, P=0.03) in levels of vWF. The corresponding differences in FVIIa and PAI-1 were not statistically significant. With further adjustment for menopausal status, family history of CHD, marital status, psychosocial stress, lifestyle patterns, biochemical factors, and hypertension, statistically significant differences between mandatory and college/university education were observed in FVII:Ag (difference=34 microg/L; 95% CI, 2 to 65 microg/L, P=0.05) but not in fibrinogen (difference=0.03 g/L; 95% CI, -0.13 to 0.19 g/L, P=0.92) or in vWF (difference=0.06 U/mL; 95% CI, -0.10 to 0.22 U/mL, P=0.45). An educational gradient was most consistent and statistically significant for FVII:Ag, fibrinogen, and vWF. Age, psychosocial stress, unhealthful life style, atherogenic biochemical factors, and hypertension mediated the association of low educational level with elevated levels of fibrinogen and vWF. Psychosocial stress and unhealthful life style were the most important contributing factors. There was an independent association between education and FVII:Ag, which could not be explained by any of these factors.  (+info)

ApoA1 reduces free cholesterol accumulation in atherosclerotic lesions of ApoE-deficient mice transplanted with ApoE-expressing macrophages. (4/4426)

Along with apolipoprotein (apo) E, which promotes cholesterol efflux from foam cells, apoA1-containing high density lipoprotein (HDL) is thought to facilitate the transport of cholesterol from lesions. This role for apoA1 was tested in vivo by lethally irradiating apoE-deficient and apoE- plus apoA1-deficient mice and reconstituting them with bone marrow cells isolated from wild-type (WT) mice. ApoE, but not apoA1, was synthesized by the transplanted bone marrow-derived cells. Therefore, this transplantation procedure generated apoE-deficient animals with atherosclerotic lesions that contained both apoE and apoA1 (E/A1 mice) and apoE-deficient animals with lesions that contained apoE but no apoA1 (E/A1o mice). As shown previously, the transplanted WT macrophage-derived apoE dramatically lowered the plasma hypercholesterolemia in both groups. On feeding with an atherogenic diet after transplantation, plasma cholesterol levels were raised in both groups of mice, but the levels in the E/A1 mice at 20 weeks were 2- to 3-fold higher than in E/A1o mice. Immunohistochemical staining verified that apoE was abundant in lesions of both groups, whereas apoA1 was detected in the lesions of E/A1 mice only. Despite a 2- to 3-fold lower total plasma cholesterol in the E/A1o mice, the free cholesterol recovered from isolated aortas was approximately 60% higher and the mean lesion area in serial sections of the aortic valves 45% larger. Therefore, apoA1 reduces free cholesterol accumulation in vivo in atherosclerotic lesions.  (+info)

Identification of megalin/gp330 as a receptor for lipoprotein(a) in vitro. (5/4426)

Lipoprotein(a) [Lp(a)] is an atherogenic lipoprotein of unknown physiological function. The mechanism of Lp(a) atherogenicity as well as its catabolic pathways are only incompletely understood at present. In this report, we show that the low density lipoprotein receptor (LDLR) gene family member megalin/glycoprotein (gp) 330 is capable of binding and mediating the cellular uptake and degradation of Lp(a) in vitro. A mouse embryonic yolk sac cell line with native expression of megalin/gp330 but genetically deficient in LDLR-related protein (LRP) and a control cell line carrying a double knockout for both LRP and megalin/gp330 were compared with regard to their ability to bind, internalize, and degrade dioctadecyltetramethylindocarbocyanine perchlorate (DiI)-fluorescence-labeled Lp(a) as well as equimolar amounts of 125I-labeled Lp(a) and LDL. Uptake and degradation of radiolabeled Lp(a) by the megalin/gp330-expressing cells were, on average, 2-fold higher than that of control cells. This difference could be completely abolished by addition of the receptor-associated protein, an inhibitor of ligand binding to megalin/gp330. Mutual suppression of the uptake of 125I-Lp(a) and of 125I-LDL by both unlabeled Lp(a) and LDL suggested that Lp(a) uptake is mediated at least partially by apolipoprotein B100. Binding and uptake of DiI-Lp(a) resulted in strong signals on megalin/gp330-expressing cells versus background only on control cells. In addition, we show that purified megalin/gp330, immobilized on a sensor chip, directly binds Lp(a) in a Ca2+-dependent manner with an affinity similar to that for LDL. We conclude that megalin/gp330 binds Lp(a) in vitro and is capable of mediating its cellular uptake and degradation.  (+info)

Effects of alcohol and cholesterol feeding on lipoprotein metabolism and cholesterol absorption in rabbits. (6/4426)

Alcohol fed to rabbits in a liquid formula at 30% of calories increased plasma cholesterol by 36% in the absence of dietary cholesterol and by 40% in the presence of a 0.5% cholesterol diet. The increase was caused almost entirely by VLDL, IDL, and LDL. Cholesterol feeding decreased the fractional catabolic rate for VLDL and LDL apoprotein by 80% and 57%, respectively, and increased the production rate of VLDL and LDL apoprotein by 75% and 15%, respectively. Alcohol feeding had no effect on VLDL apoprotein production but increased LDL production rate by 55%. The efficiency of intestinal cholesterol absorption was increased by alcohol. In the presence of dietary cholesterol, percent cholesterol absorption rose from 34.4+/-2.6% to 44.9+/-2.5% and in the absence of dietary cholesterol, from 84.3+/-1.4% to 88.9+/-1.0%. Increased cholesterol absorption and increased LDL production rate may be important mechanisms for exacerbation by alcohol of hypercholesterolemia in the cholesterol-fed rabbit model.  (+info)

Low-density lipoprotein particle size is inversely related to plasminogen activator inhibitor-1 levels. The Insulin Resistance Atherosclerosis Study. (7/4426)

High levels of plasminogen activator inhibitor-1 (PAI-1) and preponderance of small dense low-density lipoproteins (LDL) have both been associated with atherosclerotic disease and with the insulin resistance syndrome (IRS). In vitro studies have shown a stimulatory effect of various lipoproteins on PAI-1 release from different cells, including endothelial cells and adipocytes. The authors sought to investigate the relation of PAI-1 to LDL particle size in a large tri-ethnic population (n=1549) across different states of glucose tolerance. LDL size was determined by gradient gel electrophoresis, and PAI-1 was measured by a 2-site immunoassay, sensitive to free PAI-1. PAI-1 was inversely related to LDL size in the overall population (r=-0.21, P<0.0001), independent of gender and ethnicity. However, the authors found a significant interaction with glucose tolerance status (P=0.035). In univariate analysis, the association between PAI-1 and LDL size was most pronounced in subjects with normal glucose tolerance (NGT, r=-0.22, P<0.0001) and weaker in impaired glucose tolerance (IGT, r=-0.12, P=0.03) and type-2 diabetes (r=-0.10, P=0.02). After adjustment for demographic variables and metabolic variables known to influence PAI-1 levels (triglyceride and insulin sensitivity), a significant inverse relation of LDL size to PAI-1 levels was only present in NGT (P=0. 023). In subjects with IGT or overt diabetes, who usually have elevated PAI-1 levels, additional factors other than LDL size seem to contribute more importantly to PAI-1 levels. The demonstrated inverse relation of LDL size and PAI-1 levels provides one possible explanation for the atherogeneity of small dense LDL particles.  (+info)

Induction of monocyte binding to endothelial cells by MM-LDL: role of lipoxygenase metabolites. (8/4426)

Treatment of human aortic endothelial cells (EC) with minimally oxidized LDL (or minimally modified LDL, MM-LDL) produces a specific pattern of endothelial cell activation distinct from that produced by LPS, tumor necrosis factor-alpha, and interleukin-1, but similar to other agents that elevate cAMP. The current studies focus on the signal transduction pathways by which MM-LDL activates EC to bind monocytes. We now demonstrate that, in addition to an elevation of cAMP, lipoxygenase products are necessary for the MM-LDL response. Treatment of EC with inhibitors of the lipoxygenase pathway, 5,8,11, 14-eicosatetraynoic acid (ETYA) or cinnamyl-3, 4-dihydroxy-alpha-cyanocinnamate (CDC), blocked monocyte binding in MM-LDL-treated EC (MM-LDL=118+/-13%; MM-LDL+ETYA=33+/-4%; MM-LDL+CDC=23+/-4% increase in monocyte binding) without reducing cAMP levels. To further investigate the role of the lipoxygenase pathway, cellular phospholipids were labeled with arachidonic acid. Treatment of cells for 4 hours with 50 to 100 microg/mL MM-LDL, but not native LDL, caused a 60% increase in arachidonate release into the medium and increased the intracellular formation of 12(S)-HETE (approximately 100% increase). There was little 15(S)-HETE present, and no increase in its levels was observed. We demonstrated that 12(S)-HETE reversed the inhibitory effect of CDC. We also observed a 70% increase in the formation of 11,12-epoxyeicosatrienoic acid (11, 12-EET) in cells treated with MM-LDL. To determine the mechanism of arachidonate release induced by MM-LDL, we examined the effects of MM-LDL on intracellular calcium levels. Treatment of EC with both native LDL and MM-LDL caused a rapid release of intracellular calcium from internal stores. However, several pieces of evidence suggest that calcium release alone does not explain the increased arachidonate release in MM-LDL-treated cells. The present studies suggest that products of 12-lipoxygenase play an important role in MM-LDL action on the induction of monocyte binding to EC.  (+info)

TY - JOUR. T1 - Contribution of cholesterol 7α-hydroxylase to the regulation of lipoprotein metabolism. AU - Cohen, Jonathan C.. PY - 1999. Y1 - 1999. N2 - Clinical studies have clearly established a relationship between bile acid synthesis and plasma LDL-cholesterol concentrations. Interruption of the enterohepatic circulation of bile acids leads to increased bile acid synthesis and a reduction in plasma LDL-cholesterol concentrations. New studies indicate that genetic variation in cholesterol 7α-hydroxylase activity accounts for a significant fraction of the inter-individual variation in plasma LDL-cholesterol concentrations in the general population, and a specific CYP7A1 allele associated with increased plasma LDL-cholesterol concentrations has been identified. Studies in which cholesterol 7α-hydroxylase was transiently overexpressed in hamsters and mice indicate that direct manipulation of cholesterol 7α-hydroxylase leads to changes in plasma LDL-cholesterol concentrations. ...
Leptin has been suggested as a possible cause of atherosclerotic disease. The small dense low-density lipoprotein cholesterol (LDL-C) has also been regarded as a new surrogate marker in atherosclerotic disease. The aim of this study was to evaluate the relationship between the leptin concentration and the small dense LDL-C concentration in Korean type 2 diabetic patients. METHODS: One hundred-ninety one type 2 diabetic patients, who did not use any medication that could affect the concentration of lipid such as statin, fibrate, thiazolidinediones and corticosteroid, were enrolled in this study. We analyzed the relationship between leptin, the small dense LDL-C and the other metabolic parameters. RESULTS: The small dense LDL-C concentrations were higher in the group with the highest tertile of the leptin value, both in males and females than those patients in the group with the lowest tertile of the leptin value. The small dense LDL-C concentrations were also higher in the group with the highest ...

Background: We and others have demonstrated that the reduced function *5 variant (rs4149056, defined by the minor, C allele) in the hepatic transporter SLCO1B1 impairs statin clearance and is associated with myopathy and premature drug discontinuation, effects that may depend on statin type. Because statins are powerful medications that lower low-density lipoprotein cholesterol (LDLc) and prevent cardiovascular (CV) events, we hypothesized that *5 carriers would have higher LDLc and an increased risk of CV events compared to noncarriers, in a statin specific manner.. Methods: We conducted a retrospective study of 3416 Caucasians from the Duke CATHGEN biorepository. Death/myocardial infarction (MI), genotype, and patient-reported statin usage data were available in 2864 patients. Of these, we identified two independent cohorts (C1, n=498; C2, n=907) with available LDLc at baseline and at 1, 2, and 3 years after cardiac catheterization. Linear mixed models tested the association between *5 and ...
In a linked research paper (doi:10.1136/bmj.e8707), Ramsden and colleagues report new data from an old trial that shed light on the long running debate on whether increasing dietary linoleic acid intake reduces the risk of cardiovascular disease (CVD) or death.1 Research conducted in the 1960s and 1970s suggested that some of the commonly occurring dietary saturated fatty acids raise total and low density lipoprotein cholesterol concentrations, whereas the omega 6 polyunsaturated fatty acid (PUFA) linoleic acid lowers total and low density lipoprotein cholesterol concentrations.2 Linoleic acid is present in high amounts in vegetable oils such as corn, sunflower, safflower, and soybean oils and in margarines made from these oils. It is the most prevalent PUFA and omega 6 PUFA in most Western diets. As a result of the effects of linoleic acid on cholesterol concentrations, lowering intake of saturated fat and increasing that of PUFAs has been a cornerstone of dietary advice, with the aim of ...
Conclusion: This study observed an inverse correlation between plasma LDL cholesterol and heart function in individuals with T2DM. Patients with higher levels of plasma LDL cholesterol had worse left ventricular function. Therefore, plasma LDL cholesterol may be a modifiable risk factor of heart failure in diabetes, but prospective studies are necessary to confirm this finding. Introduction...
Cardiovascular disease risk reduced with lower LDL cholesterol and blood pressure combination. Study lead investigator Brian Ference explained, [The results] demonstrate for the first time that LDL cholesterol and SBP [systolic blood pressure] have independent, multiplicative, and cumulative causal effects on the risk of cardiovascular disease. This suggests that a simple strategy that encourages long-term exposure to the combined reduction of both one mmol/L in LDL-C and 10 mm Hg SBP has the potential to largely eliminate the lifetime risk of cardiovascular disease - with a reduction of up to 90 percent.. The study looked at genetic risk factors from 102,773 individuals. Participants were divided into four groups based on their calculated genetic score: the reference group, a group with an LDL cholesterol genetic score below the median (resulting in lower LDL cholesterol), a group with a systolic blood pressure genetic score below the median (resulting in lower systolic blood pressure), and ...
The exposure allele for each single nucleotide polymorphism (SNP) was associated with a lower LDL-C level that varied significantly between 2.6 and 16.7 mg/dl. Among the included SNPs, the reduction in risks of CHD ranged between 6% and 28%. All nine polymorphisms were associated with a highly consistent reduction in the risk of CHD per 38.7 mg/dl lower LDL-C, with no evidence of heterogeneity of effect (I2 = 0.0%). In a meta-analysis combining nonoverlapping data from 312,321 participants, naturally random allocation to long-term exposure to lower LDL-C was associated with a 54.5% (95% confidence interval, 48.8-59.5%) reduction in the risk of CHD for each 38.7 mg/dl lower LDL-C. This represents a three-fold greater reduction in the risk of CHD per unit lower LDL-C than that observed during treatment with a statin started later in life (p = 8.43 × 10-19).. ...
This study shows that elevated LDL cholesterol levels in a Utah kindred, indicative of clinical FH, are linked to a region on chromosome 1p32. We have previously shown that this pedigree is clearly not linked to the LDL receptor or apo B gene,8 and additional markers near each gene in this study confirm the absence of linkage. A gene within a 17-cM region on chromosome 1 appears to be the major determinant of the observed elevated LDL cholesterol. There may be additional genes with minor effects on LDL cholesterol levels on chromosomes 3 and 17 in this pedigree. The LDL cholesterol levels of this pedigree are similar to those of FH pedigrees with known LDL receptor mutations, and penetrance is complete even at young ages. Triglyceride levels are significantly lower than in FH pedigrees, but mean age and body mass index are also lower. There were no differences in the frequency of tendon xanthomas. Therefore, genotyping to determine linkage or the presence of mutations appears to be necessary to ...

Whether lipid profiles should be measured in the fasting or nonfasting state is a hot topic (1)(2). The fasting state is that used conventionally (3)(4); however, it would be much simpler for patients worldwide if a lipid profile could be taken at any time of the day, irrespective of the time since and the content of the last meal. In both the US and Europe, LDL cholesterol is currently considered the most important measurement in a lipid profile (3)(5).. Direct assays for measuring LDL cholesterol are widely available and used in many laboratories; however, even if LDL cholesterol measured with a direct method gives results similar to those calculated with the Friedewald equation, it is unclear how the 2 measurements compare in predicting ischemic cardiovascular disease. In this issue of Clinical Chemistry, Mora et al. report on an evaluation of fasting LDL cholesterol concentrations calculated with the Friedewald equation vs direct measurement of fasting and nonfasting LDL cholesterol ...

TY - JOUR. T1 - Mechanisms by which saturated triacylglycerols elevate the plasma low density lipoprotein-cholesterol concentration in hamsters. Differential effects of fatty acid chain length.. AU - Woollett, L. A.. AU - Spady, D. K.. AU - Dietschy, J. M.. PY - 1989/7. Y1 - 1989/7. N2 - These studies were designed to elucidate how shorter (MCT) and longer (HCO) chain-length saturated triacylglycerols and cholesterol interact to alter steady-state plasma LDL-cholesterol levels. When either MCT or HCO was fed in the absence of cholesterol, there was little effect on receptor-dependent LDL transport but a 36-43% increase in LDL-cholesterol production. Cholesterol feeding in the absence of triacylglycerol led to significant suppression of receptor-dependent LDL transport and a 26-31% increase in LDL-cholesterol production. However, when the longer chain-length saturated triacylglycerol was fed together with cholesterol there was a marked increase in the suppression of receptor-dependent LDL ...

Goldberg says the therapy reduces LDL cholesterol levels by at least 50 percent. Sometimes as much as three-quarters of a patients LDL will be removed during treatment. Since LDL tends to build up again, patients must receive treatment twice a month. The H.E.L.P. system is designed primarily for people with inherited genetic defects that cause their LDL cholesterol levels to be extremely high. To be eligible for the H.E.L.P. therapy, a person must have an LDL cholesterol level of more than 300 after at least six months of drug treatment to lower cholesterol along with diet and lifestyle changes. People who already have been diagnosed with cardiovascular disease are eligible if their LDL cholesterol levels remain above 200 after maximum tolerated therapy.. For more information on H.E.L.P. treatments, call 314-362-3500.. ...

BACKGROUND: Reducing low-density lipoprotein cholesterol (LDL-C) levels lowers the risk of consequences of cardiovascular disease. Research has confirmed these benefits in elderly patients. The 3-hydroxy-3-methylglutaryl coenzyme A inhibitors (ie, statins) have long-standing proven efficacy in reducing levels of LDL-C and total cholesterol.. OBJECTIVE: The goal of this study was to compare change in LDL-C from baseline and National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) III LDL-C goal attainment in a population of elderly patients (aged , or =65 years) treated with rosuvastatin versus other statins in routine clinical practice.. METHODS: This was a retrospective cohort analysis using medical and pharmacy claims data linked to clinical laboratory results from a large managed care health plan of commercial and Medicare Advantage members in the United States. Included were members aged , or =65 years who were newly treated with statins (index date) from August 1, 2003, ...
So why is it that doctors dont tell patients who suffer from elevated LDL or bad cholesterol levels to stop eating foods high in saturated fat and cholesterol and advise them to take statins like Zocor, Crestor and Lipitor when in reality doctors should be telling patients about policosanol and CoQ10? The truth is that of course your doctor should be recommending that their patients who suffer from elevated LDL cholesterol levels to eat healthier with proper diet, to lose weight and exercise but perhaps doctors know that patients may not comply to their recommendations about proper diet to lower unhealthy cholesterol levels. But why would doctors recommend that their patients take statins like Zocor, Lipitor or Crestor is unimaginable, simply because of what drugs like Lipitor, Crestor and Zocor do to necessary CoQ10 production. What good will statins like Crestor, Zocor and Lipitor do for cholesterol levels and CoQ10 production? They will lower LDL cholesterol levels with a hit or miss ...
Simvastatin is a cholesterol-lowering agent that has been demonstrated to reduce both normal and elevated low-density lipoprotein cholesterol concentrations.
their meta-analysis included 3 studies with major limitations: a significant decrement in low-density lipoprotein cholesterol levels over the study period in the placebo arm (Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial [ALLHAT]), old age at therapy initiation (Pravastatin in Elderly Individuals at Risk of Vascular Disease [PROSPER] Study), and incomplete information on low-density lipoprotein cholesterol levels over the follow-up period (Air Force/Texas Coronary Atherosclerosis Prevention Study [AFCAPS/TexCAPS]). All these studies showed negative results; their inclusion would have biased against finding a benefit to statin treatment ...

Aim of the study Although low-density lipoprotein cholesterol (LDL-C) has been consistently demonstrated a predictor of atherosclerotic disease in a large spectrum of clinical settings, among individuals aged of 80 years or older this concept is uncertain. This study was evaluated in a carefully selected population if the association between LDL-C and coronary atherosclerotic burden remains significant in the very elderly. Methods Individuals aged of 80 years or older (n = 208) who spontaneously sought primary prevention care and have never manifested cardiovascular disease, malnutrition, neoplastic or consumptive disease were enrolled for a cross-sectional analysis. Medical evaluation, anthropometric measurements, blood tests and cardiac computed tomography were obtained. Results In analyses adjusted for age, gender, diabetes, systolic and diastolic blood pressure, smoking and statin therapy, no association was found between coronary calcium score (CCS) and LDL-C [1.79 (0.75-4.29)]. There was ...
Treatments for high ldl cholesterol consists of increasing bodily exercise, a change in weight-reduction plan, and taking medications. In a 2013 clinical study published in the British Medical Journal, Canadian researchers compared the diabetes risk of five standard statins to the danger of Pravachol, a statin found to significantly cut back the likelihood of developing diabetes in a earlier research. Ezetimibe reduces whole ldl cholesterol, LDL or dangerous ldl cholesterol and triglycerides, and increases HDL (good) ldl cholesterol. Fibrates may also assist improve the quantity of good ldl cholesterol (HDL ldl cholesterol). In the brain, however, cholesterol performs a crucial role in the formation of neuronal connections-the important links that underlie reminiscence and studying.. However, for those who nonetheless insist to cease taking your ldl cholesterol medicine, you may also need to vary your way of life as nicely.

BACKGROUND: Combining lipid-lowering agents with complementary mechanisms of action can provide greater cholesterol reductions than using either agent alone, improving achievement of target low-density lipoprotein cholesterol (LDL-C) levels.. OBJECTIVES: The aim of this study was to assess the effects of fluvastatin extended-release (XL) 80 mg/d administered alone or combined with ezetimibe 10 mg/d on plasma lipid levels and inflammatory parameters in patients with primary hypercholesterolemia. The tolerability of both regimens was also evaluated.. METHODS: In this multicenter, randomized, open-label, parallel-group study, patients with hypercholesterolemia were randomized in a 1:1 ratio to receive fluvastatin XL 80 mg/d alone or in combination with ezetimibe 10 mg/d for 12 weeks. The primary end point was the percentage change from baseline to week 12 in LDL-C level with fluvastatin XL + ezetimibe combination therapy compared with fluvastatin XL alone. Plasma concentrations of inflammatory ...
One of the aims of this study was to assess the association of low density lipoprotein (LDL) cholesterol levels with diabetes risk.

The truth is, weve always had reason to question the idea that cholesterol is an agent of disease. Indeed, what the Framingham researchers meant in 1977 when they described LDL cholesterol as a marginal risk factor is that a large proportion of people who suffer heart attacks have relatively low LDL cholesterol. So how did we come to believe strongly that LDL cholesterol is so bad for us? It was partly due to the observation that eating saturated fat raises LDL cholesterol, and weve assumed that saturated fat is bad for us. This logic is circular, though: saturated fat is bad because it raises LDL cholesterol, and LDL cholesterol is bad because it is the thing that saturated fat raises. In clinical trials, researchers have been unable to generate compelling evidence that saturated fat in the diet causes heart disease. The other important piece of evidence for the cholesterol hypothesis is that statin drugs like Zocor and Lipitor lower LDL cholesterol and also prevent heart attacks. The ...
What lipid tests should I follow? Mainstream cardiology tends to focus mostly on LDL-C and not LDL-P or LDL size and density. This is partly because statins and other lipid-lowering drugs do not change the size and density of the LDL, and they may lower LDL-C more than LDL-P.16Nutritional changes, on the other hand, seem to be more effective at improving LDL-P and LDL size.17 Therefore, when measuring the impact of lifestyle changes on your lipids, we recommend getting advanced lipid testing that includes LDL-P and the size of the LDL particles.. Unfortunately, in the U.S. and other countries, insurance may not cover these tests, so you may have to pay out of pocket for them. If that is prohibitive, you may be able to use the triglyceride-to-HDL ratio as a surrogate for the size of LDL particles. It isnt perfect, but it does tend to correlate with metabolic health. Studies show that TG/HDL ratios correlate with cardiovascular risk and cardiovascular mortality. Although there isnt universal ...

A remaining problem involves the laboratory aspects of measuring triglyceride-rich lipoproteins or lipoprotein subclass distribution. One method for determining the presence of triglyceride-rich particles is by determination of apoproteins associated with these particles. However, only a few large clinical trials have used this approach.19 28 The presence of large or small LDL and IDL and VLDL mass in many of the investigations mentioned above has been determined by ANUC at the LBNL. This is the same method as that pioneered by Drs John Gofman and Frank Lindgren. Although it provides tremendous detail, its clinical use is hindered by the expense and the expertise required to maintain and operate the system. Other techniques are available, including density gradient ultracentrifugation and GGE. Of these, GGE has been used in the largest number of clinical trials and can provide detailed information on LDL particle size and percent distribution in seven LDL subclasses.29 The GGE method at the LBNL ...
A total of 3,481 participants (45-74 years, 53.1% women) were included. In men, all baseline risk factors showed a significant association with CAC except for high-density lipoprotein cholesterol (HDL-C), serum creatinine, and glomerular filtration rate. For women, the association to risk factors was similar, but not significant for smoking and serum creatinine. After 5 years, the demographics in men showed a higher body mass index with a higher prevalence of obesity and diabetes and higher glycated hemoglobin level. Systolic blood pressure was higher and diastolic blood pressure was lower despite a higher use of antihypertensive agents. A lower prevalence of smoking as well as lower low-density lipoprotein cholesterol levels with a higher rate of lipid-lowering medication was also observed. The 5-year follow-up data in women showed very similar trends. The difference between observed and predicted CAC5y (log-scale, mean ± standard deviation) was 0.08 ± 1.11 and 0.06 ± 1.29 in men and women. ...

Ever since Anitschkows pioneering experiments on the role of cholesterol in the causation of atherosclerotic plaques in rabbits (2), this intriguing molecule has been at the heart of debate and controversy (3). Initially, the total cholesterol level was used as a measure of risk, then a distinction between α- and β-lipoproteins emerged. As the role of specific lipoproteins became clear, attention focused on the cholesterol content of low-density lipoprotein (LDL), which constitutes the major cholesterol-carrying lipoprotein in serum. The National Cholesterol Education Programs Adult Treatment Program (ATP), first published in 1988, recommended using the LDL cholesterol level as the marker for initiating treatment as well as for gauging therapeutic target goals (4). The well orchestrated campaign that followed these guidelines familiarized the medical community with LDL cholesterol. Since then numerous clinical studies have confirmed the value of nutritional and pharmacologic treatment of ...

Cholesterol is a type of fat that is principally made in the liver (about 75%), and with a smaller contribution from animal source (through diet). Cholesterol cannot dissolve in blood and therefore travels to and from cells on transporters or carriers known as lipoproteins. The types of lipoproteins involved in this transport include low-density lipoprotein (LDL) and high-density lipoprotein (HDL).. Cholesterol carried by LDL is referred to as LDL-cholesterol (LDL-C). It is a bad cholesterol that can build up in the wall of arteries causing what is called atherosclerosis and consequently lead to heart attack, , stroke, disease of the arteries of the lower limbs known as peripheral arterial disease or claudication (that typically presents as lower limb pain, often occurring after walking a predictable distance). Other consequences of the damage to arteries (atherosclerosis) resulting from high LDL-C include narrowing of arteries of the kidney (which may lead to a condition known as renovascular ...
According to the data behind that chart, a person could have a relatively high level of LDL cholesterol, such as greater than 160 mg/dL, and not be affected by a high level of cardiac risk. A person with elevated levels of CRP, indicating systemic inflammation, would be likely to have a higher level of cardiac risk even if his/her LDL cholesterol level was moderate, lower than 130 mg/dL. But if both the LDL cholesterol and the CRP levels were in the highest range, the cardiac risk would be apt to be very high indeed.. The LDL-C levels considered as low in these graphics are based on the guidelines promulgated by the National Cholesterol Educational Program (NCEP) Adult Treatment Panel III in 2001, which used 130 mg/dL as the cutpoint for borderline high LDL-C. More recently, many clinicians have argued for a target LDL-C reading of about 100 mg/dL in individuals with no specific cardiac risk factors, and below 70 mg/dL in persons with one or more risk factors. Thus, the data above could be ...
Actemra recommended use is limited to patients who have failed other approved therapies because of serious safety concerns that were noted in clinical studies. These safety concerns include elevated liver enzymes, elevated Low-density lipoprotein (LDL) or bad cholesterol, hypertension, and gastrointestinal perforations.. Physicians and patients need to be aware of the risk of serious adverse effects of Actemra and make informed decisions regarding its benefits and risks in the treatment of individual patients, said Bob Rappaport, M.D., director of the Division of Analgesics, Anesthetics and Rheumatology Products in the FDAs Center for Drug Evaluation and Research.. The FDA is requiring the sponsor to conduct a post-marketing clinical trial to further evaluate the long-term safety of Actemra.

Dengue virus (DENV) is a flavivirus of worldwide importance, with approximately 4 billion people across 128 countries at risk of infection, and up to 390 million infections and 96 million clinically apparent cases estimated annually. Previous in vitro studies have shown that lipids and lipoproteins play a role in modifying virus infectivity. However, the relationship between development of severe dengue and total cholesterol, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C), respectively, is unclear. We analyzed data from 789 laboratory-confirmed dengue cases and 447 other febrile illnesses (OFI) in a prospective pediatric hospital-based study in Managua, Nicaragua between August 2005 and January 2013, using three different classifications of dengue severity: World Health Organization (WHO) 1997, WHO 2009, and standardized intervention categories. Total serum cholesterol and LDL-C levels decreased over the course of illness and were generally lower ...

Table I shows, firstly, the mean total cholesterol concentration of each fifth of the distribution based on the original measurements in the cohort of 21 515 men (the group of 5696 men had the same original values); secondly, the mean total cholesterol concentration; thirdly, the mean low density lipoprotein cholesterol concentration of each fifth based on the repeat measurements in the group of 5696 men; and fourthly, the age adjusted death rates for ischaemic heart disease for the five groups. The threefold difference in mortality from ischaemic heart disease across the groups (1.11 to 3.11 deaths per 1000 man years) corresponded to a difference in original total cholesterol concentration of 3.1 (from 4.8 to 7.9) mmol/l but a smaller difference in repeat total cholesterol concentration of 2.2 (5.0 to 7.2) mmol/l; this is the regression dilution bias. The threefold difference in mortality from ischaemic heart disease corresponded to an even smaller difference in low density lipoprotein ...

The characters of dyslipidemia are the hypertriglyceridemia, low high-density lipoprotein cholesterol and small dense low-density lipoprotein cholesterol. As to the patient having a cardiovascular disease (such as coronary artery disease, stroke, or peripheral artery occlusion) or the diabetes mellitus, the 2001 National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) III suggests reducing the serum low-density lipoprotein cholesterol with statin. However, there remains a relatively high residual risk of morbidity or mortality in patients with the metabolic syndrome or diabetes mellitus, and this is of growing importance because of the increasing ...
Low-frequency coding DNA sequence variants in the proprotein convertase subtilisin/kexin type 9 gene (PCSK9) lower plasma low-density lipoprotein cholesterol (LDL-C), protect against risk of coronary heart disease (CHD), and have prompted the development of a new class of therapeutics. It is uncertain whether the PCSK9 example represents a paradigm or an isolated exception. We used the Exome Array to genotype |200,000 low-frequency and rare coding sequence variants across the genome in 56,538 individuals (42,208 European ancestry [EA] and 14,330 African ancestry [AA]) and tested these variants for association with LDL-C, high-density lipoprotein cholesterol (HDL-C), and triglycerides. Although we did not identify new genes associated with LDL-C, we did identify four low-frequency (frequencies between 0.1% and 2%) variants (ANGPTL8 rs145464906 [c.361C|T; p.Gln121*], PAFAH1B2 rs186808413 [c.482C|T; p.Ser161Leu], COL18A1 rs114139997 [c.331G|A; p.Gly111Arg], and PCSK7 rs142953140 [c.1511G|A; p.Arg504His])
People with low levels of LDL cholesterol are more likely to have Parkinsons disease than people with high LDL levels, according to University of North Carolina at Chapel Hill researchers. LDL stands for low-density lipoprotein cholesterol; low levels of LDL cholesterol are considered an indicator of good cardiovascular health. Earlier studies have found intriguing correlations between Parkinsons disease, heart attacks, stroke and smoking.. People with Parkinsons disease have a lower occurrence of heart attack and stroke than people who do not have the disease, said Dr. Xuemei Huang, medical director of the Movement Disorder Clinic at UNC Hospitals and an assistant professor of neurology in the UNC School of Medicine. Parkinsons patients are also more likely to carry the gene APOE-2, which is linked with lower LDL cholesterol. And for more than a decade, researchers have known that smoking, which increases a persons risk for cardiovascular disease, is also associated with a decreased ...
Lipoprotein concentrations have been associated with the major risk of bleeding events. However, whether plasma levels of LDL-C are associated with the risk of biopsy-related endobronchial hemorrhage remain elusive. Therefore, the present study was initiated to investigate the explicit association of low-density lipoprotein cholesterol (LDL-C) with endobronchial biopsy (EBB)-induced refractory hemorrhage in patients with lung cancer. This retrospective study included a total of 659 consecutive patients with lung cancer who had undergone EBB at a tertiary hospital between January 2014 and April 2018. Using multiple regression analysis, the association between LDL-C and the risk of EBB-induced refractory hemorrhage was assessed after adjusting for potential confounding factors. A significant proportion (13.8%, 91/659) of the patients experienced refractory hemorrhage following EBB. In multivariate regression analysis, higher plasma LDL-C concentrations were associated with increased risk of EBB-induced
BACKGROUND Extended follow-up of statin-based low-density lipoprotein cholesterol lowering trials improves the understanding of statin safety and efficacy. Examining cumulative cardiovascular events (total burden of disease) gives a better appreciation of the clinical value of statins. This article evaluates the long-term impact of therapy on mortality and cumulative morbidity in a high-risk cohort of men. METHODS AND RESULTS The West of Scotland Coronary Prevention Study was a primary prevention trial in 45- to 64-year-old men with high low-density lipoprotein cholesterol. A total of 6595 men were randomized to receive pravastatin 40 mg once daily or placebo for an average of 4.9 years. Subsequent linkage to electronic health records permitted analysis of major incident events over 20 years. Post trial statin use was recorded for 5 years after the trial but not for the last 10 years. Men allocated to pravastatin had reduced all-cause mortality (hazard ratio, 0.87; 95% confidence interval, ...
OBJECTIVES: Peroxisome proliferator activated receptor delta (PPARD) is a transcription factor implicated in the regulation of genes involved in cholesterol metabolism. We recently discovered a common polymorphism in the 5-untranslated region (5-UTR) of the human PPARD, +294T/C, that is associated with an increased plasma low-density lipoprotein cholesterol (LDL-C) concentration in healthy subjects. Whether the +294C allele is associated with LDL-C elevation independently of the background lipoprotein phenotype and whether it confers increased risk of coronary heart disease (CHD) is unknown. Against this background, we investigated the relationships between the PPARD polymorphism and plasma lipoprotein concentrations and the risk for contracting CHD in the West of Scotland Coronary Prevention Study (WOSCOPS). DESIGN: A nested case-control study of participants in a randomized double-blind placebo-controlled trial of pravastatin in mildly-to-moderately hypercholesterolaemic men. SUBJECTS: A total of

OBJECTIVE: To determine the quantitative importance of dietary fatty acids and dietary cholesterol to blood concentrations of total, low density lipoprotein, and high density lipoprotein cholesterol. DESIGN: Meta-analysis of metabolic ward studies of solid food diets in healthy volunteers. SUBJECTS: 395 dietary experiments (median duration 1 month) among 129 groups of individuals. RESULTS: Isocaloric replacement of saturated fats by complex carbohydrates for 10% of dietary calories resulted in blood total cholesterol falling by 0.52 (SE 0.03) mmol/l and low density lipoprotein cholesterol falling by 0.36 (0.05) mmol/l. Isocaloric replacement of complex carbohydrates by polyunsaturated fats for 5% of dietary calories resulted in total cholesterol falling by a further 0.13 (0.02) mmol/l and low density lipoprotein cholesterol falling by 0.11 (0.02) mmol/l. Similar replacement of carbohydrates by monounsaturated fats produced no significant effect on total or low density lipoprotein cholesterol. Avoiding
We present experimental evidence that, in Ossabaw miniature swine, selective surgical excision of adipose tissue in direct contiguity with one of the epicardial coronary arteries attenuated the progression of atherosclerosis, thus supporting the hypothesis that cEAT could contribute to underlying coronary atherogenesis [13]. The findings are applicable to the early stages of CAD because of the relatively young age of the animals, the short duration of atherogenic diet feeding, and the lack of observed flow-limiting coronary stenosis typical of advanced clinical disease. We acknowledge the substantially high LDL cholesterol levels (,500 m/dL) in the obese group. We have conducted other studies in which the LDL was ~250 mg/dL (e.g. [10, 12]) for a longer duration, which yielded substantial coronary atherosclerosis. We predict a similar result of adipectomy. This very high LDL cholesterol level for a short duration is similar to LDLR−/− humans, who have substantial atherosclerosis. Horton and ...
Green tea consumption is linked to reduce incidence of cardiovascular disease. The meta-analysis at hand suggests that the benefits are related to reduced total and LDL cholesterol. I suspect its more complicated than that. Collectively, consumption of green tea lowers LDL cholesterol and TC, but not HDL cholesterol or triglycerides in both normal weight subjects…
BACKGROUND: Hypercholesterolemia is an important risk factor for cardiovascular disease (CVD). OBJECTIVE: To compare the efficacy of a 12-week treatment regimen with HEP-40TM low-molecular weight chitosan given at daily doses of 1,200 mg, 1,600 mg, and 2,400 mg in reducing serum low-density lipoprotein cholesterol (LDL-C) in patients with low-to-moderate hypercholesterolemia. DESIGN: The study was a 16-week, multicenter, placebo-controlled, randomized study. Eligible patients were treatment-naive for lipid-lowering medications. Patients were randomly assigned to HEP-40 at the following doses: 400 mg three times daily, 800 mg twice daily, 800 mg three times daily, 2,400 mg once daily, or placebo for 12 weeks. The main outcome measure was the percent change in LDL-C after four weeks of treatment. RESULTS: Out of 283 patients screened, 105 (37.1%) fulfilled the inclusion criteria and 95 (90.4%) completed the study. The mean (SD) age was 53 (11) years and 62.3 percent were male. The majority of ...
Researchers find that eating almonds regularly may help improve HDL cholesterol levels, functionality. Eating almonds on a regular basis may help boost levels of HDL cholesterol while simultaneously improving the way it removes cholesterol from the body, according to researchers.. In a study, researchers compared the levels and function of high-density lipoprotein (HDL cholesterol) in people who ate almonds every day, to the HDL levels and function of the same group of people when they ate a muffin instead. The researchers found that while participants were on the almond diet, their HDL levels and functionality improved.. Penny Kris-Etherton, distinguished professor of nutrition at Penn State, said the study, published in the Journal of Nutrition, builds on previous research on the effects of almonds on cholesterol-lowering diets.. Theres a lot of research out there that shows a diet that includes almonds lowers low-density lipoprotein, or LDL cholesterol, which is a major risk factor for ...
Diet plans that are low in saturated fat and cholesterol, high in fiber, and also reduced in salt are the most effective selections for a healthy diet regimen. Reducing cholesterol with diet plan alone can minimize the risk of heart diseases such as coronary artery illness (CAD) and also stroke. Individuals with high blood pressure must also make an initiative to maintain their high blood pressure reduced. Blood pressure boosts the danger of creating cholesterol-related problems, so it needs to be regulated also. Ldl Cholesterol Numbers. Smoking cigarettes or utilizing other tobacco products has actually been received numerous research studies to elevate LDL cholesterol levels as well as decrease HDL cholesterol degrees. This is why stopping smoking is so crucial. Other contributors to cholesterol include weight problems, physical lack of exercise, alcohol intake, and also the existence of other threat elements, such as diabetic issues, heart problem, and cancer. Additionally, some drugs, ...
BACKGROUND:Periprocedural myocardial injury (PMI) is known to be a predictor of postprocedural cardiovascular morbidity and mortality following a percutaneous coronary intervention (PCI). However, the correlation between low-density lipoprotein cholesterol and periprocedural myocardial injury in patients following elective PCI in southern China remains unclear. Therefore, we aimed to investigate the association of preoperative low-density lipoprotein cholesterol (LDL-C) levels with PMI in patients following elective PCI. MATERIAL AND METHODS:This study included 1942 consecutive patients who received elective PCI. Cardiac troponin I (cTnI) was used to assess perioperative myocardial injury. The peak cTnI was measured within 24 h after PCI, and the correlation between the cTnI value and the preoperative LDL level was studied. RESULTS:The data suggest that the PCI patients with preprocedural LDL-C |100 mg/dl were strongly and independently correlated with less risk of PMI. Univariate logistic regression
Having high cholesterol levels may be risky for people with a history of heart disease. In the same way, people should also know that there are two kinds of cholesterol- the good, or HDL cholesterol and the bad, or LDL cholesterol. And since your body needs a certain amount of cholesterol to function properly, you need to raise the HDL cholesterol and lower your LDL cholesterol levels. Here are some simple tips tha ...
The Treating to New Targets (TNT) trial compared atorvastatin 80 mg (aiming at reducing LDL cholesterol | or = 75 mg/dl) and atorvastatin 10 mg (LDL | or = 100 mg/dl as target) in 10,001 patients with stable coronary heart disease followed up for 5 years. A reduction of major cardiovascular events of 22% was observed in the atorvastatin 80 mg group as compared to the atorvastatin 10 mg group (hazard ratio: 0.78; 95 % interval of confidence: 0.69-0.89; p | 0.001). Such clinical efficacy was obtained while a good drug safety profile was maintained. Total mortality was not significantly different between the two groups. However, and remarkably, cardiovascular death was not the first cause of death anymore in this atorvastatin-treated population. The results of TNT in patients with stable coronary heart disease thus confirm the results of PROVE-IT in patients with acute coronary syndrome. These two randomised controlled trials should encourage considering a LDL cholesterol level of 75 mg/dl (rather than
Technically, there is no pure cholesterol in your bloodstream. Cholesterol is transported by lipoproteins. LDL (reduced-density lipoproteins) and HDL (high-density lipoprotiens) are the lipoprotiens utilised to transport cholesterol.. Tests can be run that really test for the cholesterol, which offers you the total cholesterol number (direct measurement). Or you can run a test for the HDL and LDL cholesterol complexes. You add these values to get a computed total cholesterol. If you run a total cholesterol AND calculate it from summing the HDL and LDL cholesterols they need to be close, but will not concur exactly. Tests have a margin of error. This is why they will not match exactly.. Though triglyerides are typically transported by lipoproteins, I do not know why they would use it to calculate total cholesterol.. We employed to run total cholesterol then and HDL, computing the LDL as a distinction among the total and HDL.. A correction to the answer above this - folic acid is not a fatty ...
The type of surgery the patients received is now only available to a few patients at high risk for heart attack and who cannot tolerate cholesterol lowering medications. The study commenced in 1975. Follow up 25 years later showed that lowering cholesterol added one more year of life for the study participants.. Anti-cholesterol medications called statins are given to lower bad LDL cholesterol levels and are the treatment of choice for preventing heart disease, peripheral vascular disease and for preventing heart attack. Henry Buchwald, M.D., Ph.D., bariatric surgeon at the University of Minnesota Medical School, and lead investigator says the study...contributes to a long path of findings from the POSCH trial, that is, high levels of LDL cholesterol are detrimental to your health. The scientists say the study finding is the only trial that looked at the life-extending benefits of lowering cholesterol over a twenty-five year span. They also say it is the only randomized controlled trial that ...
BY FRED G. ARNOLD, NMD. It is a common belief by many medical professionals that statin drugs lower the Incidence of cardiovascular disease by lowering LDL cholesterol. However, a recent study in the Journal of Clinical Nutrition shows that LDL cholesterol levels do not lower heart disease risk and do not lower the incidence of you dying from a heart attack. LDL cholesterol levels are considered the bad cholesterol and is why many doctors prescribe statin drugs to lower it. In this recent study the researchers evaluated 1,469 women between the ages of 72-78 and the relationship between their LDL levels and their chances of dying from cardiovascular disease for a 10 year period. During this time, 134 women died from cardiovascular disease that had nothing to do with high LDL levels. The women with the highest levels of LDL cholesterol were no more at risk than those with the lowest levels! They discovered that Baseline serum total and LDL cholesterol were not associated with atherosclerotic ...
Limited research has been available to support a link between elevated cholesterol concentrations and risk of ischaemic stroke. The study by Collins et al provides nurses with definitive evidence that supports the use of statins to reduce stroke in high risk populations. Reduced risk of stroke was reported within just 2 years of simvastatin use. The resultant reduction in low density lipoprotein (LDL) cholesterol concentrations of 1.0 mmol/l was associated with a 21% risk reduction in stroke. These reductions were reported in patients with and without elevated LDL cholesterol concentrations at baseline and with overall medication adherence rates of 85%.. High risk patients are often confused when they are prescribed statins by consultants if their cholesterol concentrations are known to be within normal range and if they have remained untreated by family physicians. When patients are not confident about the need for a prescribed medication or are concerned about side effects, there is a risk of ...
in reply: We appreciate the comments regarding our article.1 With regards to our recommendations for the treatment of hypertriglyceridemia using statins, Dr. Raghavan suggests that fibrates, niacin, or fish oil should play a more prominent role. We agree with his comments about the pharmacotherapy of patients with very high levels of serum triglycerides (at least 500 mg per dL [5.65 mmol per L]), which is supported in our article. However, for patients with lower degrees of triglyceride elevation (between 200 and 499 mg per dL [2.26 to 5.64 mmol per L]) the current treatment guidelines emphasize low-density lipoprotein (LDL)-cholesterol as the main target of therapy, followed by non-high-density lipoprotein cholesterol.1 The overwhelming literature on the benefit of statins recommends it as a first-line option in patients with no contraindications who are at moderate to high cardiovascular risk and have elevated LDL cholesterol levels.. Dr. Raghavan also purports that our algorithm is ...
Methods Totally 445 subjects were investigated during physical examination by recording genders and age, measuring height, weight, body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP), concentrations of serum uric acid (SUA), total cholesterol (TC), triglycerides (TG), serum high density lipoprotein cholesterol (HDL-C), serum low density lipoprotein cholesterol (LDL-C) and fasting blood glucose (FBG). The physical examination results were analysed with statistical method.. ...
The aim of this work was to evaluate reverse cholesterol transport (RCT) in hamster animal model expressing cholesterol ester transfer protein under a high-cholesterol diet (HF) supplemented with ezetimibe using primary labeled macrophages. We studied three groups of hamsters (n = 8/group) for 4 weeks: 1) chow diet group: Chow, 2) high-cholesterol diet group: HF, and 3) HF group supplemented with 0.01% of ezetimibe: HF + 0.01%Ezet. After intraperitoneal injection of 3H-cholesterol-labeled hamster primary macrophages, we measured the in vivo macrophage-to-feces RCT. HF group exhibited an increase of triglycerides (TGs), cholesterol, and glucose in plasma and higher TG and cholesterol content in liver (P , 0.01) compared with Chow group. Ezetimibe induced a significant decrease in plasma cholesterol with a lower low-density lipoprotein (LDL) and very LDL cholesterol (P , 0.001) and in liver cholesterol (P , 0.001) and TG (P , 0.01) content compared with HF. In vivo RCT essay showed an increase of ...
The preferred first-line treatment in pharmacologically altering cholesterol is by use of HMG-CoA reductase inhibitors, more commonly referred to the a statins.. Following over four decades of clinical use, Statin experts acknowledge that statins are the most prominent factor in increasing longevity in individuals with excess cholesterol, regardless of the source.. In stating the benefits of lowering cholesterol, cholesterol experts and statin experts reference clinical studies, the accumulation of which now exceed 100,000 patients in published, peer-reviewed clinically-controlled studies, that using statins to meaningfully lower LDL (low-density lipoprotein) cholesterol, will prevent early death in those with high LDL cholesterol.. The clinical outcomes data is overwhelmingly positive with regards to the benefits of cholesterol-lowering through the use of statins. Experts will concur that although the lowering of LDL-levels with statins, the complete and full ability to use statins to treat ...
HDL, or good cholesterol picks up excess cholesterol and takes it back to your liver.. Factors within your control - such as inactivity, obesity and an unhealthy diet - contribute to high LDL cholesterol and low HDL cholesterol. Factors beyond your control may play a role, too. For example, your genetic makeup may keep cells from removing LDL cholesterol from your blood efficiently or cause your liver to produce too much cholesterol.. ...
Though statins rule the roost when it comes to carry down and controlling the blood ranges of bad ldl cholesterol, the option of utilizing various medicine is at all times there - for its effectiveness, lesser value and minimal unintended effects. Me how low/excessive my cholesterol is. They do the lipo fasting kind and undecided if that is the same factor. Nicotinic acids are used to lower levels of cholesterol to treat high ldl cholesterol, excessive triglycerides, and coronary artery illness. Statins additionally increase the amount of cholesterol that the liver takes up and removes from the blood. And some medicine of this sort may very well raise levels of cholesterol in individuals with liver illness ...

Upon concluding this study, researchers discovered that spirulina supplementation could have a positive effect on lowering lipids, mainly triglycerides.. Reducing blood pressure: One study, conducted in Mexico, evaluated a group of 16 men and 20 women - who had no diagnosed history of cardiovascular disease or diabetes - for six weeks. During the six weeks, participants were told not to modify their lifestyle or diet. Participants were given three .5 gram tablets of spirulina every eight hours over these six weeks. What they discovered at the end of the study is spirulina does have lipid-lowering effects particularly on low-density lipoprotein cholesterol (LDL-C) and Triacylglycerol (adipose tissue used for energy storage) as well as positive effects on lowering overall blood pressure. The ultimate determination being? Spirulina could is a useful supplement for dyslipidemic and hypertensive patients.. Allergies/Chronic Sinus Issues: Do you suffer from seasonal allergies or chronic sinus ...
Variants in the cholesterol ester transfer healthy protein as well as lipoprotein lipase genes are predictors of plasma cholesterol feedback to nutritional modification. A meta-analysis of 67 controlled trials of nutritional soluble fiber as a single intervention revealed that the impacts on total cholesterol and LDL cholesterol degrees were small. An extensive evaluation of plant stanols as well as sterols showed that these compounds lower LDL cholesterol degrees in persons at danger of coronary heart disease.15 This testimonial included a meta-analysis of 41 tests showing that 2 g each day of either stanols or sterols decreases LDL website cholesterol degrees by 10 percent. Executive Summary of the Third Report of the National Cholesterol Education Program (NCEP) Specialist Panel on Discovery, Assessment, and also Treatment of High Blood Cholesterol in Grownups (Grownup Therapy Panel III).

Evinacumab (Regeneron) appears to have a dramatic effect on low-density lipoprotein (LDL) cholesterol levels in patients with homozygous familial hypercholesterolemia (HoFH) with little or no LDL receptor activity, suggests a post hoc analysis of phase 3 trial data.. The results, which one expert described as a game changer for these patients, were presented at the European Atherosclerosis Society 2020 Virtual Congress on October 5, held online this year because of the COVID-19 pandemic.. The phase 3 ELIPSE trial showed that evinacumab, a human monoclonal antibody inhibitor of angiopoietin-like 3 (ANGPTL3), given intravenously every 4 weeks reduced LDL cholesterol levels in HoFH patients by an average of 47%.. As reported by , Medscape Cardiology, the treatment, which was generally well tolerated, was also effective in the approximately one third of patients with minimal residual LDL receptor activity.. Now, Frederick Raal, MD, PhD, the University of the Witwatersrand, ...
The strategy underlying the addition of a second or third agent is to optimize improvements in the lipid profile achieved by initial (usually statin) therapy. This strategy is based on the empirical assumption that further improvement in the lipid profile beyond that initially achieved will yield additional CVD benefit. However, there are as yet no controlled clinical trials comparing statin monotherapy with combination treatment.. It has been clearly shown that the addition of ezetimibe to a statin will lower LDL cholesterol to goal more often than statin monotherapy will.28 Bile acid sequestrants may also help to lower LDL cholesterol but should be used with caution because they have a triglyceride-raising effect in hypertriglyceridemic patients.29. It is also clear that achievement of all three lipid goals is more likely with statin plus fibrate or statin plus niacin combinations.30-32 However, the added complexity and risks of combination therapy in the absence of persuasive clinical trial ...
ABSTRACT: The principal dietary strategy to reduce low-density lipoprotein cholesterol (LDL-C) levels is to decrease the amount of saturated fat and cholesterol in the diet. Consumption of soluble fibers, plant sterol and stanol esters, nuts, and soy protein further reduces LDL-C levels. Soluble fibers, such as psyllium, lower LDL-C levels by increasing bile acid loss, interrupting enterohepatic circulation of cholesterol, and reducing hepatic cholesterol delivery. Plant stanol and sterol esters, which are added to margarine, mayonnaise, and olive oil, are effective LDL-C-lowering agents. Nuts such as almonds and walnuts reduce LDL-C levels and have been associated with a 30% to 50% reduction in coronary heart disease risk. A diet that combines the above elements, plus soy protein, reduces LDL-C levels as much as starting doses of statins.
Ideal Cholesterol levels are extremely beneficial for maintaining a disease free body. In order to prevent heart diseases and diabetes, we should keep the percentage of LDL lower than HDL. LDL or bad cholesterol can cause damage to your body while HDL or good cholesterol promotes good health.. How To Maintain A Healthy Cholesterol Level And Lower The LDL?. . There are various ways to maintain cholesterol level and lower LDL (Low Density Lipoprotein). Cardio workouts, balanced diet, Yoga and meditation can be the best ways to lead a healthy life.. . Exercising regularly encourages metabolism in our body. It not only helps your body to lose weight but also reduces LDL. By performing cardio workouts such as running, swimming, brisk walking or aerobics, our body can reach ideal cholesterol levels. Drinking sufficient water is the main requisite during the entire process. You should drink at least 10-12 glasses of water daily.. . There are foods, which can easily lower the LDL. You should consume ...
The Penn State study shows that low LDL cholesterol levels may actually be dangerous and lead to an increased risk of hemorrhagic stroke. This is when a blood vessel bursts in the brain.. Lead author Dr. Xiang Gao, an associate professor of nutritional science at Penn State wrote, As is true with many things in nutrition, moderation and balance is key when deciding the optimal target level of LDL cholesterol. You cant go to either extreme - too high or too low.. Doctors typically recommend that patients get their LDL cholesterol levels below 100 milligrams per deciliter. Patients at high risk of heart problems are often put on cholesterol lowering drugs to ensure their levels stay below 70 milligrams per deciliter. But, pushing the LDL level too low may increase ones risk of hemorrhaging stroke by 65%.. The study involved roughly 96,000 participants from Tangshan, China. None of the participants had a family history of heart attack, cancer or stroke. Doctors measured the participants ...
It is important to know your levels of cholesterol because there are no outward symptoms to alert you of your condition. Low-density lipoprotein (LDL), also known as the bad cholesterol, contributes to hypercholesterolemia and can lead to narrowing of the arteries especially with the presence of inflammation. High-density lipoprotein (HDL), or good cholesterol, helps rid the body of bad cholesterol by cleaning up the excess LDL and sending it to the liver, where it is broken down. Your total cholesterol levels should be less than 200 mg/dl, with your LDL cholesterol levels ideally below 100mg/dl and HDL cholesterol levels above 60 mg/dl to give you protection from heart disease.. Beginning with an initial consultation, one of our Tao of Wellness doctors will evaluate both your current cholesterol levels and the physical and lifestyle factors that may have led your body to its current state of imbalance. Chinese medicine is a holistic practice that considers all aspects of your history in ...

  • My understanding is that the statins with the greatest LDL reducing effect are Crestor, Lip. (
  • Statins have long been the drug of choice to reduce LDL cholesterol. (
  • My late mother bragged that her cholesterol was under 200 but her HDL was very low and she took statins. (
  • Additional research has shown that statins, drugs used to treat high LDL cholesterol appear to also protect the heart in other ways. (
  • Huang cautioned that people should not change their eating habits, nor their use of statins and other cholesterol-lowering drugs, because of the results. (
  • Cholesterol has been demonized and statin drugs (Zocor, Crestor, Lipitor, Baycol, Mevacor or Altocor, Pravachol, Lescol, Livalo) have been touted as miracle drugs for lowering cholesterol, yet as we've seen use of statins increase we've seen heart disease as well as diabetes increase. (
  • Numerous classes of drugs including statins, fibric acid derivatives, bile acid sequestrants, nicotinic acid, and cholesterol absorption inhibitors are available to not only reduce cholesterol but also improve overall cholesterol profile. (
  • Amgen Inc. ( AMGN ) Sunday reported positive results from phase 1b study of AMG 145, an investigational PCSK9 inhibitor, in patients with high cholesterol who were taking statins. (
  • The study revealed that multiple doses of the drug significantly reduced LDL, or bad cholesterol, by up to 81 percent compared to placebo in patients on low to moderate doses of statins. (
  • In the 51-patient study, the subjects who received AMG 145 every two weeks in combination with low to moderate doses of statins had LDL reductions of up to 75 percent versus placebo at sixth week. (
  • Meanwhile, the subjects who received AMG 145 in combination of low to moderate doses of statins every four weeks showed up to a 66 percent reduction in LDL at eighth week. (
  • Patients on high doses of statins who received AMG 145 every two weeks had a reduction in LDL of up to 63 percent versus placebo at sixth week, the company said. (
  • For patients with high LDL, or bad, cholesterol the primary focus of treatment is to lower their levels, but many patients today do not achieve recommended levels despite lifestyle modifications and treatment with statins,' said Christopher Cannon, M.D., Professor of Medicine at Harvard Medical School, Cardiovascular Division at Brigham and Women's Hospital, and a member of the Steering Committee for the Phase 3 ODYSSEY clinical trial program. (
  • Many patients in the U.S. face the challenge of achieving LDL cholesterol levels recommended by healthcare providers, despite treatment with standard of care including statins. (
  • In the ODYSSEY LONG TERM trial which evaluated Praluent 150 mg every two weeks, Praluent reduced LDL cholesterol by 58 percent versus placebo at week 24 when added to current standard of care, including maximally tolerated statins. (
  • In ODYSSEY COMBO I, Praluent 75 mg every two weeks as an adjunct to statins reduced LDL cholesterol by an additional 46 percent compared to placebo at week 12. (
  • Reductions in LDL cholesterol levels with combination therapy (32 to 48 percent) were significantly superior to colesevelam or statins alone (7 to 16 percent and 22 to 34 percent, respectively). (
  • Combination therapy also decreased total cholesterol levels 6 to 10 percent more than statins alone, but did not impact HDL or triglyceride levels, whereas atorvastatin alone decreased triglyceride levels. (
  • Ischemic stroke patients with lower levels of low-density lipoprotein cholesterol, including those on statins, may be at increased risk of developing a brain hemorrhage after recanalization therapy, regardless of other risk factors, according to a March 6 study in Neurology (68:737-742). (
  • We're not in any way advocating not taking statins, but our study suggests that something is going on and we'll need new studies to see if the risk is real and if there is an LDL threshold below which the risk increases," he told Neurology Today . (
  • Prior studies have shown that pre-stroke statin use may improve ischemic stroke outcomes, yet there is also evidence that statins and extremely low cholesterol levels may increase the risk of intracranial hemorrhage. (
  • Statins, a type of LDL cholesterol-lowering drug, were recently shown to have a significant, positive association with newly diagnosed cancer cases. (
  • Following the adage, "lower is better," intensive LDL cholesterol lowering has been practiced by physicians on their patients throughout America since 1987, with Lovastatin and more recently with a new generation of statins. (
  • So we asked what component in LDL cholesterol could be the common link between statins and decreased cellular oxygen? (
  • We also know that statins, by design, reduce the amount of cholesterol. (
  • Nevertheless, with the new advancements in clinical medicine, it has now become possible to bring down the LDL levels to as low as 15 mg/dl using PCSK9 monoclonal antibodies alone or in combination with statins. (
  • The American College of Cardiology/American Heart Association (NCEP IV) guidelines recommend prescription of evidence-based doses of statins independent of the LDL level [ 3 ]. (
  • In fact, study authors report that patients with side effects were more than three times more likely to miss the cholesterol target than those without side effects, and that those who did not take their statins were three times more likely to miss the target than patients who did take them. (
  • The studies thus far that have been carried out where we've used PCSK9 inhibitors on top of maximal-tolerated statins drives LDL down 20 [mg/dL] and below, and so far, what we've seen has been reassuring in that the lower the better in terms of reducing cardiovascular events, and the treatments have been safe. (
  • Gotto presented telling data from a number of those studies, with some examining statins alone and others focusing on combinations with proprotein convertase subtilisin/kexin type 9 ( PCKS9) inhibitors as they relate to not only reducing LDL levels, but also to protecting against adverse CV outcomes. (
  • According to Gotto, LDL cholesterol and risks for coronary heart disease, myocardial infarction or mortality were significantly reduced or numerically lowered in four trials that compared different doses of various statins, including intensive atorvastatin therapy, simvastatin and pravastatin, which are considered more standard therapy. (
  • Gotto went on to present findings from the FOURIER and ODYSSEY trials, which exhibited how PCSK9 inhibitors can further enhance the work of statins in yielding LDL cholesterol reductions and CV benefits. (
  • In the FOURIER trial, evolocumab (Repatha, Amgen) treatment was compared with placebo in a population of individuals already using statins who had LDL cholesterol levels of at least 70 mg/dL and atherosclerotic CVD. (
  • We talked about who benefits from taking statins, is LDL really the "bad" cholesterol, and how to keep your blood thin and protect yourself from heart attacks and strokes, naturally. (
  • There are prescription medications called statins that many physicians prescribe to their patients to lower their cholesterol levels. (
  • However, the problem with statins is that while they do help lower your LDL cholesterol levels, they have almost no effect on HDL (good) cholesterol. (
  • Also, some patients in the group with high LDL cholesterol levels could have received statins during the study which could have had a protective effect, which the authors acknowledge as a limitation of their study. (
  • What did Americans do before the advent of plant oils, margarine, cholesterol-free soy protein, fat-free dairy, and statins? (
  • A class of drugs called statins blocks cholesterol synthesis and is used extensively in treating heart disease. (
  • Too much LDL cholesterol in the blood can cause deposits of fats to build up in the walls of the arteries (atherosclerosis). (
  • People with familial hypercholesterolaemia have high cholesterol from birth and are at high risk of developing atherosclerosis at a young age. (
  • Lower LDL levels are better, to a point, but a recommended goal is a blood level of less than 130 mg/dL among people who do not have atherosclerosis or diabetes. (
  • Elevated levels of LDL-C are associated with an increased risk of hardening of the arteries (atherosclerosis) and heart disease. (
  • The reason for such a large number of poor responders may lie in the prevalence of metabolic abnormalities linked to atherosclerosis that are not detected on routine laboratory tests and hence are not adequately treated with just LDL-C reduction. (
  • 6 Knowledge of a patient's Lp(a) value is of particular use in predicting atherosclerosis risk when other risk factors, such as high LDL-C, are present. (
  • HDL (high density lipoprotein) cholesterol is called the 'good' cholesterol because HDL cholesterol particles prevent atherosclerosis by extracting cholesterol from artery walls and disposing of them through liver metabolism. (
  • High levels of LDL cholesterol and low levels of HDL cholesterol are risk factors for narrowing of the arteries in the body (atherosclerosis). (
  • In univariate analyses, the percent change in the levels of LDL cholesterol, CRP, apolipoprotein B-100, and non-high-density lipoprotein cholesterol were related to the rate of progression of atherosclerosis. (
  • LDL cholesterol is an unhealthy form of cholesterol that collects in the walls of blood vessels and causes blockages of atherosclerosis. (
  • For this reason the LDL-Cholesterol concentration is considered to be the most important clinical predictor, of all single parameters, with respect to coronary atherosclerosis. (
  • Accurate measurement of LDL-Cholesterol is of vital importance in therapies which focus on lipid reduction to prevent atherosclerosis or reduce its progress and to avoid plaque rupture. (
  • LDL cholesterol is considered the "bad" cholesterol, because it contributes to fatty buildups in arteries ( atherosclerosis ). (
  • There is a chemical found in cigarettes, called acrolein that stops HDL cholesterol from travelling to the liver and causes atherosclerosis (narrowing of the arteries). (
  • The research on natural substances affecting cholesterol metabolism for prevention of hypercholesterolemic atherosclerosis has particular therapeutic importance. (
  • Compared to baseline and the other diets, the avocado diet lowered levels of small, dense LDL particles, which are a risk factor for atherosclerosis. (
  • LDL cholesterol is harmful, but small, dense LDL particles are particularly dangerous because they are better able to get into artery walls where plaque forms, thus promoting atherosclerosis. (
  • They are also more easily oxidized, and oxidized LDL plays an important role in atherosclerosis. (
  • Autopsies of thousands of young accident victims have shown that blood cholesterol levels were closely correlated with the amount of atherosclerosis in their arteries. (
  • That's where we start out at birth, that's the level seen in populations largely free of heart disease, and that's the level at which the progression of atherosclerosis appears to stop in cholesterol-lowering trials. (
  • The level of LDL is the single most important marker of atherosclerosis (Figure 1 ). (
  • LDL is the "bad cholesterol" a high level of these in the blood stream is often thought to be the cause, in part, to several conditions such as heart disease and atherosclerosis. (
  • Because of the patient's high LDL-C concentration and family history of atherosclerosis, she was referred for a cardiology evaluation. (
  • Cigarette smoking is linked to higher cholesterol levels as well as the formation of a damaging form of LDL called oxidized LDL , which contributes to atherosclerosis . (
  • Cholesterol travels through the blood on proteins called "lipoproteins. (
  • Cholesterol is transported around the body in the bloodstream on proteins called lipoproteins. (
  • HDL (high-density lipoprotein, or "good" cholesterol) and LDL (low-density lipoprotein, or "bad" cholesterol) are two types of lipoproteins that carry cholesterol to and from the body's cells in the blood. (
  • There is a third type of cholesterol called VLDL (very-low-density lipoproteins), which is another type of "bad" cholesterol produced in the liver, and contains a high amount of triglycerides. (
  • LDL and HDL are two types of lipoproteins. (
  • Cholesterol is carried through the blood on two types of proteins called lipoproteins . (

(
  • Lipoproteins allow lipids such as triglycerides and cholesterol to be transported into the blood stream and from there to tissue. (
  • HDL is known as 'good' cholesterol because a high level of HDL or high density lipoproteins helps to protect against heart attack. (
  • Cholesterol in low density lipoproteins can be measured specifically and precisely by optically measuring a reaction product of a living sample with cholesterol oxidase or cholesterol dehydrogenase in the presence of an amphoteric surfactant. (
  • This invention relates to a process for measuring cholesterol in low density lipoproteins (hereinafter referred to as "LDL") present in living body samples such as serum, plasma, etc. (
  • The lipoproteins can be classified by differences in density into high density lipoproteins (HDL), low density lipoproteins (LDL), very low density lipoproteins (VLDL), and chylomicrons (CM), etc. (
  • Among these lipoproteins, HDL has a function of carrying excess cholesterol deposited on tissues to a liver, and has an anti-asteriosclerotic action. (
  • High-density lipoproteins (HDLs), also known as good cholesterol, act like waste removal carriers. (
  • Low-density lipoproteins (LDLs), also known as bad cholesterol, keep blood cholesterol circulating in your bloodstream, leaving plaque on artery walls along the way. (
  • LDL-C is usually not measured directly but is a calculated from the results of the other components of the lipid profile, including total cholesterol , HDL cholesterol (HDL-C) , and triglycerides (see Common Questions #3 for the formula). (
  • total cholesterol , high-density lipoprotein cholesterol (HDL-C) , and triglycerides . (
  • A direct LDL-C may be ordered by your healthcare practitioner when prior test results have indicated high triglycerides. (
  • Triglycerides show what you have recently eaten, and cholesterol shows what you have eaten over a long period. (
  • The liver then packages these triglycerides as fats in your adipose tissue, and turns some of it into cholesterol. (
  • Like cholesterol, you need some triglycerides to keep the body healthy, but increased levels can cause health problems. (
  • Triglycerides also are part of a cholesterol profile, and these numbers are more indicative of the amount of fats you have eaten recently. (
  • The guidelines recommend you have a complete 'lipoprotein profile' that measures total cholesterol, LDL cholesterol, high-density lipoprotein (HDL, the good cholesterol that may help prevent heart disease), and triglycerides, another type of fat in the blood stream. (

  • Many natural nutrients can not only lower LDL cholesterol, but can increase HDL (good) cholesterol and decrease triglycerides (fats). (
  • People who eliminate trans fat and carbohydrates from grains (soda, pasta, bread, desserts) see major drops in bad cholesterol and triglycerides despite continuing to eat cholesterol-rich foods like red meat, eggs, cream, and butter. (
  • High blood triglycerides generally mean lower HDL cholesterol, higher risk of heart attack & stroke. (
  • In most cases, the formula provides a good estimate of the LDL-C, but it becomes less accurate with increased triglyceride levels (i.e., above 400 mg/dL). (
  • Calculated LDL-C is about as accurate as direct LDL-C when triglyceride levels are normal and can be done at no additional cost as part of a lipid profile. (
  • In most cases, calculated LDL-C is a good estimate of the LDL-C, but it becomes less accurate with increasing triglyceride levels. (
  • In some laboratories, the direct LDL test will automatically be performed when the triglyceride levels are too high to calculate LDL-C. This saves the healthcare practitioner time by not needing to order another test, saves you time by not needing to have a second blood sample drawn, and speeds up the time to provide the test result. (

  • Therefore, the cholesterol in LDL (hereinafter referred to as "LDL-cholesterol) is regarded as a risk factor for arteriosclerosis, and ischemic heart disease (coronary arteriosclerotic disease). (
  • They go on to challenge the foundation of cholesterol-lowering treatments by questioning the idea that LDL cholesterol causes clogged coronary arteries. (
  • LDL transports cholesterol to the arteries, and when the LDL level is elevated, this cholesterol can accumulate in the blood vessel walls and contribute to the formation of a plaque. (
  • It is considered to be undesirable and is often call "bad" cholesterol because it deposits excess cholesterol in blood vessel walls and contributes to hardening of the arteries and heart disease. (
  • Increased numbers of LDL cholesterol indicate more risk for blocked arteries and health problems. (
  • LDL causes the build-up of fatty deposits within your arteries, reducing or blocking the flow of blood and oxygen your heart needs. (
  • It is sometimes called the "bad" cholesterol because a high LDL level leads to a buildup of cholesterol in your arteries. (
  • Since HDL helps to remove LDL from your arteries, if you have less HDL, that can contribute to you having a higher LDL level. (
  • It helps keep the LDL type in check by carrying the bad cholesterol away from the arteries and back to the liver, where it's passed from the body. (
  • Low-density lipoprotein is unhealthy cholesterol that results in clogged arteries, while high-density lipoprotein is healthy cholesterol that pushes LDL ou. (
  • HDL cholesterol, the "good" cholesterol helps carry other cholesterol particles from tissues and blood back to the liver, including helping to remove "bad" or LDL cholesterol from plaques in arteries. (
  • Experts believe that HDL acts as a scavenger, carrying LDL (bad) cholesterol away from the arteries and back to the liver, where the LDL is broken down and passed from the body. (
  • An excess of LDL cholesterol causes fatty deposits (or plaques) to build up inside your arteries. (
  • These include approximately 8-10 million patients with an inherited form of high LDL cholesterol known as heterozygous familial hypercholesterolemia and those with clinical ASCVD, defined as a build-up of plaque in the arteries which can lead to reduced blood flow and a number of conditions including heart attack, stroke, chest pain (stable or unstable angina), transient ischemic attack, revascularization and peripheral artery disease. (
  • Indeed, LDL is called "bad" cholesterol because it's the vehicle by which cholesterol is deposited into our arteries. (
  • Excess cholesterol found in these particles sticks to artery walls, spurring the growth of plaque, which hardens and clogs arteries, and limits the flow of blood and oxygen to the heart, brain, and other tissues. (
  • When a person has too much LDL cholesterol circulating in the blood, it can slowly build up within the walls of the arteries feeding the heart and brain. (
  • Medical experts think HDL tends to carry cholesterol away from the arteries and back to the liver, where it's passed from the body. (
  • In fact, there's good reason to question the reigning " lipid hypothesis ", which posits that dietary cholesterol clogs the arteries and leads to heart disease. (
  • LDL (bad) cholesterol builds up in the arteries not from how many omelets you eat, but in response to inflammation. (

  • Among high-risk patients, achieving a LDL cholesterol level far below the most common treatment target of 70 mg/dL (1.8 mmol/L) can further reduce the risk for an adverse cardiovascular event, with no major safety concerns," said Robert P. Giugliano, MD, a senior investigator in the TIMI Study Group at Brigham and Women's Hospital and a cardiovascular physician who presented the data at ESC. (

  • Results indicate that 57% of patients were not meeting the European guideline LDL target of 1.8 mmol/L at follow-up. (
  • Gone are the recommended LDL- and non-HDL-cholesterol targets, specifically those that ask physicians to treat patients with cardiovascular disease to less than 100 mg/dL or the optional goal of less than 70 mg/dL. (
  • As a result, the new guidelines make no recommendations for specific LDL-cholesterol or non-HDL targets for the primary and secondary prevention of atherosclerotic cardiovascular disease . (
  • Dr Donald Lloyd-Jones (Northwestern University Feinberg School of Medicine), the cochair of the guidelines on the assessment of cardiovascular risk , which were also released today along with guidelines for the management and treatment of obesity and guidelines for lifestyle management, said the evidence for treating to target simply isn't there, but that doesn't mean repeated measurements of LDL cholesterol won't be needed.

(
  • Given the previous results from the FOURIER trial and the findings from this new analysis, patients - particularly those at a high risk for future cardiovascular events - should review their LDL cholesterol with their physicians and discuss whether it could be beneficial to lower that level beyond what they have achieved with diet, lifestyle modifications and statin therapy," said Giugliano. (
  • The drug, which costs approximately $14,000 annually, was approved for use in the United States in 2016 as an addition to statin therapy and lifestyle changes for lowering LDL cholesterol in some adults with cardiovascular disease. (
  • While such a change may seem small at plain sight, the researchers noted that "for each 1 mg reduction in LDL cholesterol, there is a concomitant 1% reduction in overall future cardiovascular disease risk. (

  • 8 Additionally, a retrospective review of 600 patients followed by cardiologists at a heart clinic revealed that only about 76% of patients achieved the recommended LDL cholesterol level of less than 100 mg/dL. (
  • What should your LDL level be? (
  • You will be diagnosed with "high cholesterol" if your non-HDL cholesterol level is higher than what your doctor thinks is ideal for you. (
  • The duration and level of exercise also parallel improvement in all aspects of cholesterol profile. (
  • The follow-up lasted a median of 5.3 years in French patients (similar to the median follow-up time in the SPARCL trial [Stroke Prevention by Aggressive Reduction in Cholesterol Level]) and 2.0 years in Korean patients. (
  • After 1 year, the mean LDL cholesterol level was 53.2 mg per decilitre in the simvastatin-plus-ezetimibe group and 69.9 mg per decilitre in the simvastatin monotherapy group. (
  • A healthy HDL cholesterol level may protect against heart attack and stroke. (
  • Your LDL level should be 100 or lower, however if you have excessive risk factors (eg. (
  • The optimal LDL cholesterol level is probably 50 or 70 mg/dL, and apparently, the lower, the better. (
  • The population target should therefore be a total cholesterol level under 150 mg/dL. (
  • Researchers at the University of California-Los Angeles (UCLA), and Sungkyunkwan University and Samsung Medical Center, in Seoul, Korea, evaluated the independent effect of statin use and admission cholesterol level on the risk of symptomatic hemorrhagic transformation (sHT) after recanalization therapy for acute ischemic stroke. (
  • One-sixth of all Americans have a total cholesterol level above the recommended 240 mg/dL, which doubles their heart disease risk. (
  • As we all know, cholesterol is an integral part of the plasma membrane, and a minimum level of LDL needs to be present to maintain structural integrity and sustain normal function of cells. (
  • In addition, at 48 months, those taking alirocumab had an average LDL cholesterol level of 66 mg/dL compared with an average of 103 mg/dL among those taking placebo. (
  • For this reason it is very important that your body keeps a higher level of HDL cholesterol. (
  • A high level of LDL cholesterol reflects an increased risk of heart disease. (
  • Al-though it's not the same as a saturated fatty acid, dietary cholesterol can also raise your blood cholesterol level. (
  • Total blood cholesterol can indicate your level of risk. (
  • Well, when it comes to what you eat, three main factors raise your blood cholesterol level. (
  • The reduction of these metabolites was also associated with a lowered blood level of LDL cholesterol (LDL-C). Variations of these three metabolites were significantly associated with 17 genes (including FADS1 and FADS2 ) and controlled by AMPK, a metformin target. (
  • A desirable level of LDL is less than 100 mg/dL. (
  • Getting involved in physical training and regular exercise has been shown to have a reducing effect on the level of LDL cholesterol in the body. (
  • If you are in poor health or have cancer cholesterol level does go down. (
  • Your optimal LDL level depend on your other heart disease risk factors. (
  • It's necessary to consult your doctor to determine the optimal LDL level for you. (
  • At the molecular level, cholesterol primarily signals by regulating lipid rafts and raft associated membrane-protein translocation. (
  • AMG 145 is a fully human monoclonal antibody that inhibits PCSK9, a protein that reduces the liver's ability to remove LDL-C from the blood. (
  • A newer class of cholesterol lowering drugs known as PCSK9 inhibitors has emerged as an effective treatment for drastically lowering LDL cholesterol beyond current treatment targets. (
  • Evolocumab is a fully human monoclonal antibody manufactured by Amgen that works by blocking proprotein convertase subtilisin-kexin 9 (PCSK9), a protein that reduces the liver's ability to remove LDL cholesterol from the blood. (
  • OVER THE PAST YEAR, new evidence for the cholesterol- fighting class of therapy called proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors has generated discussion about the usefulness of these powerful drugs in diabetes care. (
  • Next, at the American Diabetes Association Scientific Sessions in June, came a pair of results for rival PCSK9 inhibitor alirocumab (Praluent, from Sanofi-Regeneron) that showed a 49% LDL cholesterol reduction for patients with T2D and a 32.5% reduction for patients with dyslipidemia. (
  • Meanwhile, the recent availability of PCSK9 inhibitors has revalidated the discussion on further lowering of LDL and has brought back the age-old question: how low is in fact low enough to bring the CV risk to the minimum? (
  • The prospect of lowering cholesterol with about the same potency as the monoclonal antibodies that block PCSK9 (proprotein convertase subtilisin/kexin type 9) activity but administered as a biannual injection "enables provider control over medication adherence, and may offer patients a meaningful new choice that is safe and convenient and has assured results," Kausik K. Ray, MD, said at the annual congress of the European Society of Cardiology. (
  • Similarly to LDL cholesterol, VLDL cholesterol can also build up inside the walls of blood vessels, which is undesirable. (
  • Chylomicrons (CMs) and very low-density lipoprotein (VLDL) are not detectable, and LDL is virtually absent. (
  • VLDL is later degraded into LDL (Low Density Lipoprotein). (
  • Stone acknowledged that the old targets might be part of the "mind-set" of physicians but said the new recommendations actually simplify treatment in that doctors won't have to fuss around with additional means to lower LDL cholesterol if the patient has been treated with an appropriate dose of statin therapy. (
  • 7 Findings from a managed care study showed that older individuals, men, and patients compliant with statin therapy were more likely to meet their LDL cholesterol goal. (
  • Ischemic stroke patients with lower LDL cholesterol had a significantly higher risk of sHT after treatment with tissue plasminogen activator (t-PA), angioplasty, or clot retrieval, independent of concurrent statin therapy or smoking. (
  • How Low Should LDL Cholesterol Go with Statin Therapy? (
  • This plan focuses on foods that are low in natural cholesterol and saturated fat but high in the so-called "good fats. (
  • LDL and HDL are the two main types of cholesterol (blood fats, or lipids) that make up your total cholesterol. (
  • Your total cholesterol is the sum of the fats in your blood, which includes the LDL and HDL cholesterol . (
  • Eating foods high in -saturated and trans fats - fast food, fatty meat like sausages, pastry, cakes and full-fat dairy products - can encourage the build-up of LDL. (
  • Most diets recommend limiting fat and cholesterol intake, specifically saturated fats and trans fatty acids, and increasing the intake of plant steroids and fiber. (
  • consequently, you should stay away from: cheese, ice cream, store-bought baked goods, and foods high in trans fats (not the same as cholesterol, but very bad for your heart health). (
  • A rare form of the disease that occurs before the age of 65, early-onset Alzheimer's has previously been linked to a gene mutation involved in how the body processes fats and cholesterol. (
  • BeWellBuzz) Despite the cultural demonizing of fats, saturated fats and cholesterol, all of these are good and necessary nutrients for life and health. (
  • Cholesterol produced in you body is a soft, waxy substance found among the lipids (fats) in the bloodstream and in all your body's cells. (
  • Cholesterol and other fats can't dissolve in the blood. (
  • These are saturated fats, cholesterol and obesity. (
  • These heart-damaging fats reduce HDL and raise LDL. (
  • Foods that are high in soluble fiber and phytosterols, as well as healthy fats such as olive oil, have been found to be helpful in lowering LDL cholesterol. (
  • People with high LDL are advised to make lifestyle changes and to use cholesterol-lowering medications if lifestyle changes alone are insufficient. (
  • Injectable drugs for people with HoFH People with high LDL may have a history of familial hypercholesterolemia (HoFH), which makes them eligible for two injectable medications. (
  • Cholesterol-lowering statin medications decrease the risk of heart disease . (
  • The type of surgery the patients received is now only available to a few patients at high risk for heart attack and who cannot tolerate cholesterol lowering medications. (
  • Renal failure, for example, has been linked to one of the leading cholesterol medications. (
  • Evolocumab has the potential to provide significant additional benefit when added to existing LDL cholesterol-lowering medications for patients with high cholesterol. (
  • More women did not reach the LDL-C target as compared to men, particularly in the subgroup treated with lipid-lowering medications. (
  • Similarly to men, they do not receive medications despite high LDL-C. These gender discrepancies increase with age and diabetes duration, exposing older women to higher CHD risk. (
  • The ingredients of this special cholesterol supplement have been shown to be much safer than the statin medications prescribed by many doctors. (
  • Cholesterol lowering medications also come with many possible adverse side effects, some of them fatal. (
  • As with all health supplements, make sure you consult your physician or other qualified medical professional before taking any cholesterol lowering supplements or statin medications. (
  • HDL carries cholesterol to the liver, where it is removed from circulation and eliminated from the body. (
  • The HDL basically pushes the LDL into your liver so that it can be processed and ejected from your body. (
  • Cholesterol in the blood originates from dietary intake and liver production. (
  • Organ meats such as liver are especially high in cholesterol. (
  • Organ meats, such as liver, are especially high in cholesterol content, while foods of plant origin contain no cholesterol. (
  • After a meal, dietary cholesterol is absorbed from the intestine and stored in the liver. (
  • Your liver makes cholesterol, and it is also in some foods, such as meat and dairy products. (
  • Your liver then removes the cholesterol from your body. (
  • HDL cholesterol, on the other hand, returns cholesterol to the liver so it can be flushed from the body. (
  • HDL accounts for ~1/3 of all blood circulating cholesterol and serves as a protective mechanism from the development of heart disease by carrying away cholesterol from vessel walls and plaque to the liver for disposal. (
  • Less commonly, genetic causes can decrease the ability of the body to metabolize cholesterol or cause the liver to produce too much cholesterol. (
  • Family history and genetic predisposition to high cholesterol, aging (men older than 45 and women older than 55), and diseases that cause the liver to produce more cholesterol or prevent it from metabolizing cholesterol are risk factors for high cholesterol. (
  • If you have diabetes, high blood pressure, hypothyroidism, kidney disease or liver disease then it is more than likely that your doctor will also assess you for high cholesterol by doing a simple fasting blood test. (
  • Cholesterol is produced by the body (liver) and is essential for normal body functioning. (
  • When newly diagnosed cancer cases were correlated with cholesterol reduction, a disturbing significant correspondence was found, and recently published as, "Effect of the Magnitude of Lipid Lowering on Risk of Elevated Liver Enzymes, Rhabdomyolysis, and Cancer, by Alsheikh-Ali, et al . (
  • Very Low Density Lipoprotein is formed in the liver, and is 80% triglyceride and is packaged with apoproteins and cholesterols to be exported into the blood stream. (
  • What approaches would be useful to confirm the nature of lipid/lipoprotein abnormalities observed in patients with cholestatic liver disease, and how can accurate LDL-C and HDL-C concentrations be determined in patients with primary biliary cirrhosis and resulting lipoprotein abnormalities? (
  • These drugs work by blocking the enzyme that the liver uses to manufacture cholesterol. (
  • On the other hand, LDL is a major carrier of cholesterol from a liver to each tissue. (
  • HDL picks up cholesterol from the blood and delivers it to cells that can use it or to the liver to be recycled or eliminated from the body. (
  • LDL is known as "bad" cholesterol because it transports cholesterol from the liver throughout the body, potentially allowing it to be deposited in artery walls. (
  • They move the cholesterol from your blood and artery walls to your liver for removal from your body. (
  • Results of the LDL-C test and other components of the lipid profile are considered along with other known risk factors of heart disease to develop a plan of treatment and follow-up. (
  • Because cholesterol is a fat (medically referred to as lipid ), elevated blood cholesterol is sometimes referred to as hyperlipidemia . (
  • Cholesterol is a chemical compound that is naturally produced by the body and is structurally a combination of fat (lipid) and steroid. (
  • There's three kinds of cholesterol numbers or lipid numbers more accurately. (
  • Lastly, given that only 1/3 of patients being treated for high cholesterol are meeting target goals and only ~1/2 of persons prescribed a lipid lowering drug are still taking the medication 6 months later, compliance and a constructive physician-patient relationship are vital to any cholesterol lowering treatment plan. (
  • Estimation of Small, Dense LDL Particles Using Equations Derived From Routine Lipid Parameters as Surrogate Markers. (
  • Cholesterol regulates the function of several membrane proteins associated with lipid rafts. (
  • For example, cholesterol directly regulates the affinity of palmitoylated proteins for GM1 containing lipid rafts. (
  • Cholesterol signaling through lipid rafts can be attenuated by phosphatidylinositol 4,5 bisphophate signaling (PIP2). (
  • In addition, the panel said that the use of LDL-cholesterol targets might result in the overtreatment of patients with nonstatin drugs. (
  • They also are the strongest predictor of failure to meet LDL cholesterol targets. (
  • The between-genders gap in reaching LDL-C targets increased with age and diabetes duration, favouring men in all groups. (
  • LDL-C management is worst in women with T2DM, who are monitored and reach targets less frequently than T2DM men. (

  • Less than 200 milligrams of dietary cholesterol. (
  • You can always talk to your doctor or dietician in more detail about how to measure how much fat and dietary cholesterol you're taking in. (
  • With the TLC Program, you must keep your intake of dietary cholesterol to less than 200 milligrams a day. (
  • Dietary cholesterol comes primarily from animal sources including meat, poultry, fish, and dairy products. (
  • While our bodies make all the cholesterol we need, dietary cholesterol is found in most animal foods: meat, poultry, eggs, seafood, and dairy products. (
  • A variety of specific foods such as walnuts and soy proteins and dietary supplements such green tea and cholesterol lowering margarines have been shown to have a modest effect in reducing cholesterol. (
  • Taking high doses of the over-the-counter dietary supplement is not how you treat high cholesterol and doing so could be dangerous. (
  • In addition, there were no significant differences in intake of carbohydrates, protein, total fat, saturated fat, dietary fiber, soluble fiber, or cholesterol associated with taking the active tablets compared with the placebo tablets. (
  • and dietary cholesterol, found exclusively in animal-derived foods, especially eggs . (
  • The American Heart Association recom-mends that your average daily intake of dietary cholesterol should be less than 300 milligrams. (
  • Dietary cholesterol is found in meat, poultry, seafood and dairy products. (
  • If you are overweight, losing weight can help lower your LDL cholesterol. (
  • And yet, we're not abandoning the measurement of LDL cholesterol, because it's perhaps our best marker of understanding whether patients are going to achieve as much benefit as they can for the dose of statin they can tolerate. (
  • Identification and treatment of individuals with high LDL or "bad" cholesterol has improved in recent years, but patients are still slipping through the cracks, according to a survey published in the Journal of the American Medical Association . (
  • Parkinson's patients are also more likely to carry the gene APOE-2, which is linked with lower LDL cholesterol. (
  • Before considering some of the reasons why patients don't meet their LDL cholesterol goals, it is important to understand what those goals are and what the criteria for treatment is. (
  • 4 The new guidelines include an optional therapeutic LDL cholesterol goal of less than 70 mg/dL for patients in the very high-risk category. (
  • In the ODYSSEY clinical trial program, two doses of alirocumab showed significant LDL cholesterol lowering in a variety of patients who were not able to adequately lower their LDL cholesterol with current standard of care alone. (
  • The majority of patients achieved their LDL-lowering goals with the 75 mg dose, when added to maximally tolerated dose of a statin, with a generally acceptable safety profile. (
  • However the elevated risk in low LDL patients was independent of any of these other factors after univariate analysis. (
  • In cardiac literature, LDL has been reduced to the mid-40s to 50 without bleeding problems, but cardiac patients are different from stroke patients. (
  • The lower a patient's LDL, the greater the risk of symptomatic bleeding is an interesting observation, but it was in a small number of patients. (
  • He told Neurology Today in a telephone interview, "These patients [with low LDL] were also older, had more diabetes, more severe strokes, and more anti-platelet and anti-coagulant therapy. (

  • A paper published today in BMJ Open suggesting that patients with high LDL cholesterol had lower or similar mortality rates has been criticised by scientists. (
  • Thus, the earlier that patients start to have lower cholesterol concentrations, the greater the risk of death. (
  • Recently, one group of researchers has challenged the connection between raised LDL and heart disease. (
  • A 2018 article published in the journal Expert Review of Clinical Pharmacology challenged the long-held belief that 'bad' LDL cholesterol causes heart disease. (
  • In fact, study author Malcolm Kendrick reported that 92% of the individuals who had high cholesterol lived longer and had less heart disease. (
  • Of all the forms of cholesterol in the blood, the LDL-C is considered the most important form in determining risk of heart disease. (
  • In addition to measuring the amount of LDL-C in blood, a test that measures the number of LDL particles (LDL-P) and/or their size may be useful in helping to determine risk of heart disease in certain people, according to some recent studies. (
  • Along with smoking and high blood pressure, raised blood cholesterol is one of the main risk factors for heart disease. (

  • The fact is, elevated low-density lipoprotein (LDL), the bad cholesterol, is a major cause of heart disease. (
  • Your heart grows healthier and stronger, and you find yourself lowering LDL cholesterol and considerably less at risk for heart disease. (
  • While it's known that individuals living with high cholesterol are at an elevated risk of developing heart disease, new research suggests that individuals living with moderately high cholesterol for a long time, who also have higher blood pressure, may have the same risk of heart disease as those who have high cholesterol for only a short period of time. (
  • Drug therapy is generally started after therapeutic lifestyle changes have failed to meet target cholesterol reduction or concomitantly when it is anticipated that therapeutic lifestyle changes will not solely be sufficient to minimize heart disease risk. (

  • This is measured by subtracting HDL cholesterol from the total cholesterol. (
  • More importantly, the amounts of each type of cholesterol are a better predictor of risk for disease than the total amount. (
  • My total cholesterol number is high but that is because I have excellent HDL, so a higher LDL is irrelevant. (
