A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.
The worsening of a disease over time. This concept is most often used for chronic and incurable diseases where the stage of the disease is an important determinant of therapy and prognosis.
Splitting of the vessel wall in the VERTEBRAL ARTERY. Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the vertebral artery, aneurysm formation, or THROMBOEMBOLISM. Vertebral artery dissection is often associated with TRAUMA and injuries to the head-neck region but can occur spontaneously.
Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.
Disorders of one or more of the twelve cranial nerves. With the exception of the optic and olfactory nerves, this includes disorders of the brain stem nuclei from which the cranial nerves originate or terminate.
An acquired or spontaneous abnormality in which there is communication between CAVERNOUS SINUS, a venous structure, and the CAROTID ARTERIES. It is often associated with HEAD TRAUMA, specifically basilar skull fractures (SKULL FRACTURE, BASILAR). Clinical signs often include VISION DISORDERS and INTRACRANIAL HYPERTENSION.
The constant checking on the state or condition of a patient during the course of a surgical operation (e.g., checking of vital signs).

Obstruction of flow in biological or prosthetic vascular grafts.
An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.
Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesized to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics.
The rhythmical expansion and contraction of an ARTERY produced by waves of pressure caused by the ejection of BLOOD from the left ventricle of the HEART as it contracts.
A network of nerve fibers originating in the upper four CERVICAL SPINAL CORD segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head.

Endogenous nitric oxide synthase inhibitor: a novel marker of atherosclerosis. (1/1328)

BACKGROUND: Exposure to risk factors such as hypertension or hypercholesterolemia decreases the bioavailability of endothelium-derived nitric oxide (NO) and impairs endothelium-dependent vasodilation. Recently, a circulating endogenous NO synthase inhibitor, asymmetric dimethylarginine (ADMA), has been detected in human plasma. The purpose of this study was to examine the relationship between plasma ADMA and atherosclerosis in humans. METHODS AND RESULTS: Subjects (n=116; age, 52+/-1 years; male:female ratio, 100:16) underwent a complete history and physical examination, determination of serum chemistries and ADMA levels, and duplex scanning of the carotid arteries. These individuals had no symptoms of coronary or peripheral artery disease and were taking no medications. Univariate and multivariate analyses revealed that plasma levels of ADMA were positively correlated with age (P<0.0001), mean arterial pressure (P<0.0001), and Sigma glucose (an index of glucose tolerance) (P=0.0006). Most intriguingly, stepwise regression analysis revealed that plasma ADMA levels were significantly correlated to the intima-media thickness of the carotid artery (as measured by high-resolution ultrasonography). CONCLUSIONS: This study reveals that plasma ADMA levels are positively correlated with risk factors for atherosclerosis. Furthermore, plasma ADMA level is significantly correlated with carotid intima-media thickness. Our results suggest that this endogenous antagonist of NO synthase may be a marker of atherosclerosis.  (+info)

Menopausal status and distensibility of the common carotid artery. (2/1328)

Although several studies have shown that exogenous estrogens have beneficial effects on arterial characteristics, the effect of endogenous estrogen on the vascular system is still unknown. In this study, distensibility, an indicator of arterial elasticity, of the common carotid artery was compared in pre- and postmenopausal women. The study comprised 93 premenopausal and 93 postmenopausal women of similar age (range, 43 to 55 years). Women were selected from respondents to a mailed questionnaire about the menopause, which was sent to all women aged 40 to 60 years in the Dutch town of Zoetermeer (n=12 675). Postmenopausal women who were at least 3 years past natural menopause or whose menses had stopped naturally before age 48, were age-matched with premenopausal women with regular menses and without menopausal complaints. The selection aimed at maximizing the contrast in estrogen status between pre- and postmenopausal women of the same age. Distensibility of the carotid artery was measured noninvasively with B-mode ultrasound and a vessel wall movement detector system. Arterial distensibility is expressed as the change in arterial diameter (distension, DeltaD) with the cardiac cycle, adjusted for lumen diameter, pulse pressure, and mean arterial blood pressure. Compared with premenopausal women, postmenopausal women had significantly lower arterial distension (DeltaD 370.5 microm [SE 9.5] versus 397.3 microm [SE 9.6]). These results suggest that the distensibility of the common carotid artery is negatively affected by natural menopause in presumed healthy women.  (+info)

TIMP-4 is regulated by vascular injury in rats. (3/1328)

The role of basement membrane-degrading matrix metalloproteinases (MMPs) in enabling vascular smooth muscle cell migration after vascular injury has been established in several animal models. In contrast, the role of their native inhibitors, the tissue inhibitors of matrix metalloproteinases (TIMPs), has remained unproven despite frequent coregulation of MMPs and TIMPs in other disease states. We have investigated the time course of expression and localization of TIMP-4 in rat carotid arteries 6 hours, 24 hours, 3 days, 7 days, and 14 days after balloon injury by in situ hybridization, immunohistochemistry, and Western blot analysis. TIMP-4 protein was present in the adventitia of injured carotid arteries from 24 hours after injury. At 7 and 14 days after injury, widespread immunostaining for TIMP-4 was observed throughout the neointima, media, and adventitia of injured arteries. Western blot analysis confirmed the quantitative increase in TIMP-4 protein at 7 and 14 days. In situ hybridization detected increased expression of TIMP-4 as early as 24 hours after injury and a marked induction in neointimal cells 7 days after injury. We then studied the effect of TIMP-4 protein on the migration of smooth muscle cells through a matrix-coated membrane in vitro and demonstrated a 53% reduction in invasion of rat vascular smooth muscle cells. These data and the temporal relationship between the upregulation of TIMP-4, its accumulation, and the onset of collagen deposition suggest an important role for TIMP-4 in the proteolytic balance of the vasculature controlling both smooth muscle migration and collagen accumulation in the injured arterial wall.  (+info)

Relationship between brain atrophy estimated by a longitudinal computed tomography study and blood pressure control in patients with essential hypertension. (4/1328)

To evaluate the relationship between blood pressure control and the progression of brain atrophy in the elderly, patients with essential hypertension and brain atrophy were longitudinally evaluated using computerized tomography (CT). The study evaluated 48 patients with essential hypertension aged 46-78 years, and 30 sex- and age-matched normotensive control subjects. The extent of brain atrophy as determined by caudate head index (CHI), the inverse cella media index (iCMI), and Evans' ratio (ER) was estimated twice at an interval of 5-9 years (mean, 6.9 years). The mean annual increases in CHI (deltaCHI), iCMI (delta iCMI), and ER (deltaER) were evaluated. Mean blood volume in the common carotid artery (BF) and the decrease in BF per year (deltaBF) were also determined. The deltaCHI, delta iCMI, and deltaER increased with age in the hypertensive subjects as well as the control group across all age groups evaluated. The deltaCHI, delta iCMI, and deltaER were significantly greater in the patients with essential hypertension in their 50 s as compared with the controls. In patients with essential hypertension aged 65 years or older, the deltaCHI, delta iCMI, and deltaER were significantly lower in the group in whom the blood pressure was controlled within the range of borderline hypertension than the groups in which it was controlled in the range of normal or mild hypertension. In the younger patients under the age of 65 with essential hypertension, blood pressure control did not affect the deltaCHI, delta iCMI, and deltaER. The deltaCHI, delta iCMI, and deltaER were significantly correlated with deltaBF in both groups. These findings indicate that control of systolic blood pressure within the range of borderline hypertension may delay the progression of brain atrophy in elderly patients with essential hypertension.  (+info)

Volume flow estimation by colour duplex. (5/1328)

OBJECTIVE: To assess the accuracy of volume blood flow using a digitised colour duplex scanner. DESIGN: Observer-blinded experimental study. MATERIALS AND METHODS: Method comparison was performed with linear regression analysis of 89 paired observations in 11 anaesthetised pigs. A Siemens Sonoline Elegra ultrasound system was used for transcutaneous volume flow estimation using invasive transit time flowmetry by Cardiomed as a reference. RESULTS: For the individual measurement we found a standard error of the estimate (SEE) of 22 ml/min. For the regression line, however, the SEE was only 0.2 ml/min. CONCLUSIONS: Digitised colour-duplex sonography has a volume flow measurement error that is too high for single measurements in the individual patient for the method to be useful in clinical decision making, but sufficient for examinations of groups and comparison of groups.  (+info)

Management of coexisting coronary artery and asymptomatic carotid artery disease: report of a series of patients treated with coronary bypass alone. (6/1328)

BACKGROUND: A retrospective chart review of 94 patients with asymptomatic high-grade carotid stenosis undergoing coronary bypass (and valve replacement in some cases) was performed to determine whether significant carotid lesions can be safely ignored in patients undergoing cardiac surgical procedures. These operations were performed during a 2-year period. PATIENTS AND METHODS: There were 55 men and 39 women, with an age range of 37-89 years. Seventy-one patients had unilateral high-grade carotid stenosis, 17 patients had bilateral high-grade lesions, and six patients had unilateral high-grade stenosis and contralateral occlusion. Associated medical problems were recorded and short-term follow-up was obtained. RESULTS: There was one perioperative stroke and no deaths in this group of patients. CONCLUSIONS: Although these data indicate that high-grade carotid stenoses may be safely ignored during cardiac surgical procedures, a multicentre prospective randomized trial is needed to determine the appropriate treatment of the patient with coexisting carotid and coronary artery disease.  (+info)

Carotid plaque, intima media thickness, cardiovascular risk factors, and prevalent cardiovascular disease in men and women: the British Regional Heart Study. (7/1328)

BACKGROUND AND PURPOSE: B-mode ultrasound is a noninvasive method of examining the walls of peripheral arteries and provides measures of the intima-media thickness (IMT) at various sites (common carotid artery, bifurcation, internal carotid artery) and of plaques that may indicate early presymptomatic disease. The reported associations between cardiovascular risk factors, clinical disease, IMT, and plaques are inconsistent. We sought to clarify these relationships in a large, representative sample of men and women living in 2 British towns. METHODS: The study was performed during 1996 in 2 towns (Dewsbury and Maidstone) of the British Regional Heart Study that have an approximately 2-fold difference in coronary heart disease risk. The male participants were drawn from the British Regional Heart Study and were recruited in 1978-1980 and form part of a national cohort study of 7735 men. A random sample of women of similar age to the men (55 to 77 years) was also selected from the age-sex register of the general practices used in the original survey. A wide range of data on social, lifestyle, and physiological factors, cardiovascular disease symptoms, and diagnoses was collected. Measures of right and left common carotid IMT (IMTcca) and bifurcation IMT (IMTbif) were made, and the arteries were examined for plaques 1.5 cm above and below the flow divider. RESULTS: Totals of 425 men and 375 women were surveyed (mean age, 66 years; range, 56 to 77 years). The mean (SD) IMTcca observed were 0. 84 (0.21) and 0.75 (0.16) mm for men and women, respectively. The mean (SD) IMTbif were 1.69 (0.61) and 1.50 (0.77) mm for men and women, respectively. The correlation between IMTcca and IMTbif was similar in men (r=0.36) and women (r=0.38). There were no differences in mean IMTcca or IMTbif between the 2 towns. Carotid plaques were very common, affecting 57% (n=239) of men and 58% (n=211) of women. Severe carotid plaques with flow disturbance were rare, affecting 9 men (2%) and 6 women (1.6%). Plaques increased in prevalence with age, affecting 49% men and 39% of women aged <60 years and 65% and 75% of men and women, respectively, aged >70 years. Plaques were most common among men in Dewsbury (79% affected) and least common among men in Maidstone (34% affected). IMTcca showed a different pattern of association with cardiovascular risk factors from IMTbif and was associated with age, SBP, and FEV1 but not with social, lifestyle, or other physiological risk factors. IMTbif and carotid plaques were associated with smoking, manual social class, and plasma fibrinogen. IMTbif and carotid plaques were associated with symptoms and diagnoses of cardiovascular diseases. IMTbif associations with cardiovascular risk factors and prevalent cardiovascular disease appeared to be explained by the presence of plaques in regression models and in analyses stratified by plaque status. CONCLUSIONS: IMTcca, IMTbif, and plaque are correlated with each other but show differing patterns of association with risk factors and prevalent disease. IMTcca is strongly associated with risk factors for stroke and with prevalent stroke, whereas IMTbif and plaque are more directly associated with ischemic heart disease risk factors and prevalent ischemic heart disease. Our analyses suggest that presence of plaque, rather than the thickness of IMTbif, appears to be the major criterion of high risk of disease, but confirmation of these findings in other populations and in prospective studies is required. The association of fibrinogen with plaque appears to be similar to its association with incident cardiovascular disease. Further work elucidating the composition of plaques using ultrasound imaging would be helpful, and more data, analyzed to distinguish plaque from IMTbif and IMTcca, are required to understand the significance of thicker IMT in the absence of plaque.  (+info)

Thromboembolic events predispose the brain to widespread cerebral infarction after delayed transient global ischemia in rats. (8/1328)

BACKGROUND AND PURPOSE: Transient distal platelet accumulation after common carotid artery thrombosis (CCAT) leads to hemodynamic, metabolic, and molecular events that may influence the response of the postthrombotic brain to secondary insults. We investigated how a thromboembolic insult would affect histopathological outcome when combined with an ischemic insult induced 24 hours later. METHODS: Three groups of rats underwent either (1) CCAT+10 minutes of normothermic 2-vessel occlusion (n=6), (2) CCAT+sham ischemia procedures (n=6), or (3) sham CCAT procedures+10 minutes of 2-vessel occlusion (n=6). At 7 days, rats were perfused for quantitative histopathological and immunocytochemical analysis. RESULTS: Rats undergoing combined insults (group 1) had significantly larger areas of ischemic injury (P<0.05) within the cerebral cortex, striatum, and thalamus compared with the other, single-injury groups. Increased ischemic damage included selective neuronal necrosis, infarction, and focal hemorrhage. By means of glial fibrillary acidic protein immunocytochemistry and lectin histochemistry, reactive astrocytes and microglia were found to be associated with widespread tissue necrosis. In contrast, infrequent infarction or CA1 hippocampal neuronal necrosis was observed in groups 2 and 3, respectively. CONCLUSIONS: A prior thromboembolic event is a risk factor for widespread cerebral infarction and hemorrhage when combined with a delayed ischemic insult. The understanding of what factors enhance the susceptibility of the postthrombotic brain to secondary insults may aid in the development of neuroprotective strategies to be applied after transient ischemic attacks to prevent the initiation of stroke.  (+info)

Common carotid artery stenosis is often diagnosed when actually looking for internal carotid artery stenosis. The methods for diagnosis include duplex ultrasound and computed tomography. The criteria for the diagnosis of common carotid artery stenosis are unclear. The convention is that a doubling of the flow velocity between adjacent artery segments denotes significant stenosis. A retrospective analysis compared duplex ultrasound of 62 patients with common carotid artery stenosis to CT. A peak systolic velocity >182 cm/sec and an end-diastolic velocity >30 cm/sec were the most accurate as assessed by receiver-operating curves. While sensitivity was not very high, specificity was better. In this analysis duplex ultrasonography was also accurate in detection of common carotid artery occlusion, albeit in a small number of patients.. ...
In anatomy, the left and right common carotid arteries (carotids) (English: /kəˈrɒtɪd/) are arteries that supply the head and neck with oxygenated blood; they divide in the neck to form the external and internal carotid arteries. The common carotid arteries are present on the left and right sides of the body. These arteries originate from different arteries, but follow symmetrical courses. The right common carotid originates in the neck from the brachiocephalic trunk; the left from the aortic arch in the thorax. These split into the external and internal carotid arteries at the upper border of the thyroid cartilage, at around the level of the fourth cervical vertebra. The left common carotid artery can be thought of as having two parts: a thoracic (chest) part and a cervical (neck) part. The right common carotid originates in or close to the neck, so contains only a small thoracic portion. There are studies in the bioengineering literature that have looked into characterizing the geometric ...
Low-level light therapy, which is a red or near-infrared light-employed therapeutic methodology, can act to help the brain repair in cases of traumatic brain injury and stroke. In this paper, we investigate the effects of near-infrared light therapy (NILT) for the recovery of blood flow of mice with cerebral hypoperfusion, which is a key mechanism leading to vascular dementia, induced by bilateral common carotid artery stenosis (BCAS). The mice are divided into three groups of 4-5 mice per group: a normal group (without BCAS operation), a BCAS group (without NILT), or a BCAS/NILT group. The LED with a peak wavelength of 810 nm and a power of 20 mW is arranged to illuminate on the top of the mouse head. The mice receive treatment from the LED source 3 times per week for one month. After the treatment, positron emission tomography is used to quantify the effects of NILT on whole brain and regional cerebral blood flow in the cortex, striatum, and hippocampus ...
In this large-scale study of subjects 65 to 85 years of age, we found an association between CCA-IMT or carotid plaques and 2 measures of motor function. The association was attenuated after adjustment for vascular risk factors, thus suggesting that CCA-IMT or carotid plaques are intermediate variables.. The most likely explanation for this association is that individuals with higher CCA-IMT values are at increased risk of cerebral white matter hyperintensities (WMHs) and silent infarcts.16-18 Previous studies have shown that WMHs are more common in subjects performing worse on several measures of gait and balance; for instance, in the Cardiovascular Health Study, several measures of motor function were associated with WMHs in subjects ≥65 years of age.17 This finding was confirmed in smaller cross-sectional19 and longitudinal studies.20,21 Alternatives mechanisms (eg, peripheral diabetic neuropathy) are less likely because adjustment for diabetes or exclusion of diabetic subjects did not ...

0002] At the present time, physicians often treat carotid artery obstructive disease with the placement of a stent. This stent is typically placed in the internal carotid artery, in the common carotid artery, or spanning both arteries with the distal portion of the stent in the internal carotid artery and the proximal portion of the stent in the distal common carotid artery. The start of this procedure necessitates the placement of either a long sheath or a guiding catheter into the common carotid artery proximal to the carotid stenosis to be treated. The placement of such a sheath or guiding catheter can often be extremely challenging due to the tortuous course for access from the aortic arch into the common carotid artery. This is particularly an issue when accessing the right common carotid artery, which typically arises as a proximal branch from the inominate artery. Many different tricks are used to try to place relatively stiff sheaths and guiding catheters into the carotid circulation. ...
The present study was undertaken to determine the presence and predictors of the subclinical atherosclerosis in obese children. Fifty obese children [mean age: 11.7 +/- 2.5 y, mean body mass index (BMI): 28.2 +/- 4.0 kg/m(2)] and 50 age- and sex-matched healthy nonobese controls (mean age: 11.4 +/- 3.73 y, mean BMI: 17.6 +/- 3.0 kg/m(2)) were enrolled in the present study. Oral glucose tolerance test was performed to all obese subjects. Common carotid artery intima-media thickness (IMT) was measured by high-resolution B-mode ultrasonography. Carotid artery IMT was significantly increased (0.0476 +/- 0.007 versus 0.033 +/- 0.011 cm; p < 0.001) in the obese group. There were significant relations between carotid artery IMT and insulin sensitivity indexes derived from fasting samples (fasting glucose to insulin ratio (FGIR; p = 0.004, r = -0.404), quantitative insulin-sensitivity check index (QUICK-1; p = 0.002, r = -0.401) and homeostasis model assessment of insulin resistance (HOMA-IR; p = 0.034, ...

Approach and Results-We tested whether M1 macrophages produce galectin-3-binding protein in vitro. Then, we measured galectin-3-binding protein and the soluble macrophage biomarkers soluble cluster of differentiation 163 and soluble cluster of differentiation 14 in 264 participants in the Womens Interagency HIV Study. Women were positive for HIV, HCV, both, or neither (66 in each group, matched for age, race/ethnicity, and smoking status). Carotid artery disease was assessed by ultrasound measurement of right distal common carotid artery intima-media thickness, distensibility, and presence of atherosclerotic lesions (IMT,1.5 mm). Plasma galectin-3-binding protein was higher in HCV+ than HCV− women (P,0.01) but did not differ by HIV status. The 3 inflammatory macrophage markers were significantly correlated with each other and negatively correlated with cluster of differentiation (CD)4+ counts in HIV-infected women. We defined a macrophage score as 1, 2, or 3 biomarkers elevated above the ...
The aim of this study is to conduct in vivo, noninvasive magnetic resonance imaging of labeled rat bone mesenchymal stem cells (BMSCs) as they home into the site of injured common carotid artery following allograft transplantation. Our study was approved by the Institutional Committee on Animal Research. Purified rat BMSCs were dual labeled with superparamagnetic iron oxide (SPIO) particle and fluorescent DiI dye, and subsequently transplanted into recipient rats injured in the left common carotid arteries. Immediately before and 3 hr, 3, 7 and 12 days after transplantation, the labeled cells were monitored in vivo using a 7T micromagnetic resonance imaging (7T micro-MRI) scanner. The signal-to-noise ratios (SNRs) at the injured sites were corroborated with histological examination using Prussian blue staining and fluorescent imaging. Rat BMSCs were labeled with SPIO and DiI at 100% efficiency. When compared with the baseline level before transplantation, the SNR decreased significantly on Days ...
A carotid web is a very rare vascular disease of the carotid artery, leading to thrombosis and ischemic stroke. A 65-year-old male patient was admitted due to left limb weakness. On arrival, he had moderate left hemiplegia, neglect, and sensory loss; the National Institutes of Health Stroke Scale score was 8. Computed tomography angiography (CTA) and magnetic resonance (MR) examination were performed to determine the cause of basal ganglia infarction. Thin-section axial CTA showed a membrane-like structure in the posterior wall of the right common carotid artery. The sagittal reconstruction image showed a membrane-like protrusion in the posterior wall of the right common carotid artery under the right carotid sinus. The MR axial T2 image showed a membrane-like high-signal protrusion into the carotid artery lumen, which was diagnosed as a right carotid web. The patient was treated with dual antihypertensive therapy by adjusting blood pressure, controlling brain edema, improving cerebral circulation, and
The common carotid artery is found bilaterally, with one on each side of the anterior neck. Each common carotid artery is divided into an external and internal carotid artery. These arteries transfer blood to the structures inside and outside of the skull.
Common carotid artery intima-media thickness (CIMT), as measured by ultrasound, has utility in stratification of the accelerated cardiovascular risk seen in rheumatoid arthritis (RA); however, the technique has limitations. Carotid magnetic resonance imaging (MRI) is emerging as a useful research tool in the general population, but has yet to be applied in RA populations. Our objectives were to describe the utility of carotid artery MRI (carotid-MRI) in patients with RA in comparison to healthy controls and to describe the association with RA disease phenotype. Sixty-four patients with RA and no history of cardiovascular (CV) disease/diabetes mellitus were assessed for RA and CV profile, including homeostasis model assessment-estimated insulin resistance (HOMA-IR) and N-terminal pro-brain natriuretic peptide (NT-proBNP). All underwent carotid-MRI (3 T), and were compared to 24 healthy controls. Univariable analysis (UVA) and multivariable linear regression models (MVA) were used to determine

BACKGROUND AND AIMS: Common mechanisms for the development of micro- and macroangiopathic diabetic complications have been suggested. We aimed to cross-sectionally investigate strength and characteristics of the association between carotid atherosclerosis and microangiopathy in type 2 diabetic patients. METHODS AND RESULTS: Common carotid artery intima-media thickness (cIMT), carotid plaque (CP) type and degree of stenosis were evaluated by ultrasound, along with the determination of anthropometric parameters, HbA1c, lipid profile, assessment of diabetic retinopathy and nephropathy, in 662 consecutive patients with type 2 diabetes mellitus (T2DM). Patients were divided according to high/low cIMT, presence/absence of CP and of retinopathy and nephropathy. Patients with CP were older, more prevalently males, past smokers, had longer diabetes duration, significantly lower HDL cholesterol and more prevalent ischemic heart disease (all p,0.05) as compared to those with cIMT , 1 mm. Microangiopathies ...
Chronic cerebral hypoperfusion (CCH) is an important risk factor of vascular dementia (VaD) and Alzheimers disease (AD). Hypoxia/ischemia in the whole brain induced by CCH causes serious damage to brain structure and function, which can lead to cognitive impairment. Two-vessel occlusion (2-VO), also known as permanent, bilateral common carotid artery occlusion, is one of the most widely used animal models (e.g., rat) of CCH to investigate the mechanisms of neurodegenerative processes. In this protocol, we present the surgical procedure for 2-VO in rats.
Aims: To investigate the association between intima-media thickness of brachial and common carotid arteries and factors of the coagulation- and fibrinolysis system with diastolic dysfunction in patients with a previous myocardial infarction. Patients and methods: One hundred and five patients, men (72 %) and women (28%) aged between 32-73 years with a history of previous acute myocardial infarction were included. An age-matched control group with no cardiovascular risk factors was used as a comparison. B-mode ultrasound of common carotid and brachial arteries and echocardiography were evaluated in all subjects. Calculated intima-media area (cIMa) of the common carotid and brachial arteries and tissue Doppler imaging (TDI) were examined. Factors of the coagulation- and fibrinolysis system were also measured. Results: Prothrombin fragment 1+2 was significantly higher in patients with previous myocardial infarction compared to the control group ( ...

CCA distensibility, defined as the change of CCA-diameter during the cardiac cycle, and CCA-IMT were evaluated by means of high-resolution B-mode carotid ultrasound examination in consecutive, first-ever IS patients (n = 193) and in age- and sex-matched control subjects (n = 106). The CCA distensibility (inverse of CCA stiffness) was significantly (P = 0.007) lower in IS (0.353 mm, 95% CI: 0.326-0.379) ...
Stroke is ranked as the number one cause of death in Vietnam and the second leading cause of death in the world. Stenosis in the carotid arteries is one of the major risk factors for stroke, making it extremely important to confirm the diagnosis. Duplex ultrasound including measurements of the peak systolic velocity is considered the most accurate method when it comes to screening of carotid stenosis. However, the survey method is user dependent and differences in the results related to the scanning technique of the examiner may occur. The aim of this study was to determine the diagnostic variability for measuring peak systolic velocity in the common carotid artery in order to investigate whether the obtained results differ depending on the examiner. 30 healthy volunteers underwent carotid duplex ultrasound performed by two different examiners. Peak systolic velocity was measured with pulsed waved Doppler caudally of the carotid bifurcation. A T-test and a Bland-Altman plot were later applied in ...

Noninvasively determined local wave speed ( c) and wave intensity (WI) parameters provide insights into arterial stiffness and cardiac-vascular interactions in response to physiological perturbations. However, the effects of incremental exercise and subsequent recovery on c and WI have not been fully established. We examined the changes in c and WI parameters in the common carotid artery (CCA) during exercise and recovery in eight young, healthy male athletes. Ultrasound measurements of CCA diameter and blood flow velocity were acquired at rest, during five stages of incremental exercise (up to 70% maximum work rate), and throughout 1 h of recovery, and noninvasive WI analysis [diameter-velocity ( DU) approach] was performed. During exercise, c increased (+136%), showing increased stiffness with work rate. All peak and area of forward compression, backward compression, and forward expansion waves increased during exercise (+452%, +700%, and +900%, respectively). However, WI reflection indexes ...

AU - Kamath, S. Ganesh. AU - Sharif, Nabeel Md. AU - Rao, V. R.K.. PY - 2011. Y1 - 2011. N2 - The prevailing vascular fluid dynamics plays an important role in the development of atherosclerosis which is one of the most wide spread disease in humans. The recent advances in computational fluid dynamics (CFD) can be useful in observing the flow behavior downstream of the stenosis. The present study investigates a simple case of 66% eccentric stenosis of an approximate model generated from Doppler scan. The blood is assumed to be incompressible, homogenous and Newtonian, while artery is assumed to be a rigid wall. The transient analysis is performed using ANSYS-10.0, commercially available Finite Element Software. The flow pattern, Wall Shear Stress (WSS) and pressure contours are observed at pre-stenotic, ...

T1DM and control groups were compared in terms of strain and stiffness parameters and no statistically significant difference was found (p , 0.05). CIMT was higher in diabetic patients than in the control group (p = 0.039). In both groups, age was correlated with all arterial stiffness and strain parameters (p , 0.05). The duration of diabetes was also correlated with β-stiffness index, distensibility, and elastic modulus in the longitudinal plane (p , 0.05). In the diabetic group, abdominal fat ratio, whole body fat ratio, and fat mass were correlated with radial and circumferential displacement and strain parameters in transverse plane, and radial displacement in longitudinal plane (p , 0.05, for each). Diabetic patients were divided into subgroups according to the presence of nephropathy and dyslipidemia. Although no significant difference was found between the groups in terms of CIMT, patients with nephropathy had higher values for transverse and longitudinal elastic modulus, pulse-wave ...

Ultrasound. An integrated modular neural network multi-feature/multi-classifier diagnostic system, including image normalization, despeckle filtering, plaque segmentation, texture and morphological feature extraction, and neural network classification has been developed for differentiating between asymptomatic and symptomatic plaques in ultrasound imaging of the carotid for the assessment of the risk of stroke. This is the only carotid plaque diagnostic system that covers all image processing steps from acquisition to diagnosis. The image normalization and texture feature extraction modules of this system are used in several cardiovascular clinics in North America, Europe, and Asia, including Columbia University, McGill University, Imperial College, Tromso University, and others. Moreover, an automated system for segmenting and computing the texture of the intima and media layer thickness of the common carotid artery as prognostic indicators for atherosclerosis versus the intima media thickness ...

Atherosclerotic cardiovascular disease is the leading cause of death worldwide. To decrease mortality and morbidity in cardiovascular disease, the development of accurate, non-invasive methods for early diagnosis of atherosclerotic cardiac and vascular engagement is of considerable clinical interest. Cardiovascular ultrasound imaging is today the cornerstone in the routine evaluation of cardiovascular function and recent development has resulted in two new techniques, tissue velocity imaging (TVI) and speckle tracking, which allow objective quantification of cardiovascular function. TVI and speckle tracking are the basis for three new approaches to cardiac and vascular monitoring presented in this thesis: wave intensity wall analysis (WIWA), two-dimensional strain imaging in the common carotid artery, and the state diagram of the heart.. WIWA uses longitudinal and radial strain rate as input for calculations of wave intensity in the arterial wall. In this thesis, WIWA was validated against a ...
Aim: To evaluate endothelial dysfunction and subclinical atherosclerosis in Behcets disease (BD) by measuring the common carotid artery (CCA) wall stiffness and carotid intima-media thickness (CIMT). Materials and methods: We prospectively evaluated CIMT and the CCA wall stillness of 34 BD patients and 28 age/sex-matched controls. CIMT measurements were performed from the posterior wall of the carotid artery approximately 10 mm proximal to the initiation of the carotid bulb using B-mode ultrasound. The stillness of the CCA was measured from the superficial wall of the CCA using shear wave elastography (SWE). SWE measurements were recorded as shear wave velocity (SWV) using m/s as a unit. Results: The mean right (0.5 +/- 0.11 mm) and left (05 +/- 0.14 nun) CIMT of the patients were significantly higher compared to the mean right (0.41 +/- 0.07 nun) and left (0.41 +/- 0.11 mm) CIMT of the healthy controls (p=0.001 and p= 0.003 respectively). The mean right (3.72 +/- 0.94 m/s) and left (3.5 +/- ...

ISSN 2078-5135.. BACKGROUND: Atherosclerosis that starts in childhood invariably advances during adulthood. AIM: We aimed to study the effect of obesity on main carotid artery intima-media thickness (CIMT) and arterial stiffness. MATERIAL AND METHODS: A total of 78 children were studied from October 2010 to February 2011. They were divided into obese (n=42, group 1) and normal (n=36, group 2). All children were subjected to physical examination, routine biochemical and haematological analysis, carotid ultrasonography and echocardiographic measurements. A detailed medical history was obtained. Body mass index (BMI) was calculated by dividing participants weight in kilograms by the square of their height in metres. Stiffness index β was calculated using blood pressure and diameter of the systolic and diastolic ...
BACKGROUND: A phenomenon of endothelial impairment, independent of classical cardiovascular risk factors, has been observed in young people. We identified subjects with persistently reduced, or declining, endothelial function during adolescence and early adulthood, without apparent cardiovascular risk, and investigated the clinical relevance of this finding. METHODS: Endothelial vasomotor responses were assessed by brachial artery flow-mediated dilatation (FMD) at age 15 years in 47 subjects (22 males) who returned for a repeated measurement at age 25. Subjects underwent quantification of left ventricular mass (LVM) and function by cardiovascular magnetic resonance, central arterial stiffness by applanation tonometry, and common carotid artery intima-media thickness using ultrasound on their visit at age 25. RESULTS: Individuals with low average FMD over 10-year period, although normotensive, had 5 mm Hg higher systolic blood pressure and, significantly greater LVM (73.48 ± 7.73 vs. 56.25 ± 9.54 g/m(2

OBJECTIVE: The purpose of this study was to examine the association between adiposity measures, ultrasound image quality, and preclinical markers of atherosclerosis in young adults. METHODS: B-mode ultrasound was used to obtain common carotid intima-media thickness and common carotid artery distensibility of 2265 and 1313 adults aged 24 to 39 years in two population-based studies: the Cardiovascular Risk in Young Finns and Childhood Determinants of Adult Health studies. Qualitative assessments of ultrasound image quality were obtained from each study (scored as 1, excellent; 2, average; and 3, poor) based on the ability to detect arterial interfaces and the amount of noise present in the image. RESULTS: Increased adiposity was associated with significantly increased odds (all P | .05) of average or poor carotid ultrasound image quality. Reduced image quality was associated with lower intima-media thickness in Young Finns (regression coefficient = -0.029; P = .01) and higher intima-media thickness in
BACKGROUND: Partial GH deficiency (GHD) in adults is poorly studied. OBJECTIVE: The objective of the study was to investigate the natural history and clinical implications of partial GHD. STUDY DESIGN: This was an analytical, observational, prospective, case-control study. PATIENTS: Twenty-seven hypopituitary patients (15 women, ages 20-60 yr) and 27 controls participated in the study. MAIN OUTCOME MEASURES: Measures included GH peak after GHRH plus arginine [(GHRH+ARG), measured by immunoradiometric assay]; IGF-I (measured after ethanol extraction) z-sd score (SDS); glucose, insulin, total cholesterol, high-density lipoprotein (HDL) cholesterol, and triglyceride levels; and common carotid arteries intima-media thickness (IMT) measured periodically. RESULTS: At study entry, partial GHD patients had significantly lower IGF-I and HDL-cholesterol levels and homeostasis model assessment index than controls. During the 60 months of median follow-up, 11 patients had severe GHD (40.7%), seven ...
Carotid artery - What are the carotid arteries? Carotic Arteries. The human carotid arteries supply the head and the neck with oxygenated blood. The left common carotid artery originates from the aorta and the right common carotid originates from the brachiocephalic artery which originates from the aorta. The carotic artery divides in the neck to form the internal and external carotic arteries.
Lefferts, W., Augustine, J., Heffernan, K., Department of Exercise Science, Syracuse University, Syracuse, NY Cross-sectional studies have identified arterial stiffness as an important correlate of cerebral blood flow (CBF) pulsatility, an important predictor of cerebrovascular damage. Central artery stiffness increases acutely following a bout of resistance exercise (RE). It has yet to be elucidated whether RE-induced increases in arterial stiffness affect CBF pulsatility. Purpose: To investigate the effects of acute RE on carotid artery stiffness and CBF pulsatility. Methods: 18 healthy men (age 22 ± 1 yr; BMI 23.7 ± 0.5 kg∙m-2) underwent a) acute RE (5 sets, 5-RM bench press, 5 sets 10-RM bicep curls with 90 s rest intervals), and b) a time control condition (seated rest) in a randomized order. CBF pulsatility index (PI) was measured with transcranial Doppler at the middle cerebral artery (MCA). Common carotid artery (CCA) beta stiffness (β) and blood flow velocity PI were assessed using Doppler
Four vessels arise sequentially from the aortic arch: the right common carotid artery, the left common carotid artery, the left subclavian artery and the aberrant right subclavian artery, which crosses upwards and to the right in the posterior mediastinum. It results from a disruption in the complex remodelling of the paired branchial arches, typically of the right dorsal aorta distal to the sixth cervical intersegmental artery. [1, 2 ...

Increased arterial stiffness assessed by increase PWV and increased pulse pressure have been shown to relate directly with cardiovascular events.23,24 Similar prognostic information can be gained from BRS evaluation in different patient populations at risk for cardiovascular complications. Previous investigations have demonstrated that BRS is significantly related to carotid artery distensibility. A positive association between the elastic properties of the carotid artery and BRS has been reported in healthy volunteers,25 pregnant women,26 hypertensive subjects,27 and nondiabetic patients with carotid artery stenosis.28 However, in this study we did not observe any correlation between BRS and common carotid artery wall distensibility in T2DM patients with at least 2 additional cardiovascular risk factors.. This T2DM population differs significantly from previously published works. We have selected high-risk subjects with T2DM who are characterized by stiffened and diseased arteries as evidenced ...
BACKGROUND:. A finding from the Cholesterol Lowering Atherosclerosis Study (CLAS), a clinical trial, indicated that common carotid intima-media thickness responded more rapidly and more markedly to LDL-C lowering treatment than angiographic coronary stenosis or carotid roughness. New data from a primate model also showed ultrasound detection of intimal thickening in response to a hypercholesterolemic diet within twelve months. These findings suggest that carotid IMT is a reliable and rapidly responding marker of extent of atherosclerosis. However, less than a third of the observed therapeutic benefit on carotid IMT found in CLAS was explained by change in LDL-C and HDL-C, suggesting that related (or other) factors are more directly linked to atherogenic mechanisms. In addition, a Finnish epidemiologic study found that LDL-C was predicative of rate of progression in carotid IMT only in persons with high serum levels of (pro-oxidant) copper. . These and other data support a model of ...
Dietary supplementation with polyphenolic antioxidants to animals was shown to be associated with inhibition of LDL oxidation and macrophage foam cell formation, and attenuation of atherosclerosis development. We investigated the effects of pomegranate juice (PJ, which contains potent tannins and anthocyanins) consumption by atherosclerotic patients with carotid artery stenosis (CAS) on the progression of carotid lesions and changes in oxidative stress and blood pressure. Ten patients were supplemented with PJ for 1 year and five of them continued for up to 3 years. Blood samples were collected before treatment and during PJ consumption. In the control group that did not consume PJ, common carotid intima-media thickness (IMT) increased by 9% during 1 year, whereas, PJ consumption resulted in a significant IMT reduction, by up to 30%, after 1 year. The patients serum paraoxonase 1 (PON 1) activity was increased by 83%, whereas serum LDL basal oxidative state and LDL susceptibility to copper ...
Cerebral ischemia-reperfusion injury is a complex process resulting in cellular damage and death. Ischemia and reperfusion in the brain induces an inflammatory response which may exacerbate initial levels of tissue injury. In this study, we investigated the possible immune modulation of rosuvastatin in brain ischemia reperfusion injury via interfering with inflammation. Twenty four adult albino rats were randomized into four groups (each of 6) as follow: Group (1) sham group: the rats were subjected to the same surgical procedures as other groups but the common carotid arteries were not occluded; Group (2) control (ischemic-reperfused) group: the rats were subjected to the same surgical procedures as other groups with bilateral common carotid arteries occlusion (BCCAO) for 30 min. followed by reperfusion for 1 hr but without drug; Group (3) control vehicle group: three days before surgery, rats received daily the vehicle of rosuvastatin drug, normal saline (0.9% Nacl) (1 ml/kg/day) ...
Background: Neurologic damage following ischemic insult is a major problem for stroke survivors. Xenon (Xe) exerts favorable neuroprotective properties with few side effects. This study describes a unique application of ultrasound for controlled release of Xe from liposomes (Xe-ELIP) for targeted therapeutic gas delivery and neuroprotection.. Method: Xe-ELIP were created by a pressurization-freezing method. One-MHz continuous ultrasound wave with pressure amplitudes of 0.16, 0.22 and 0.33 MPa was used to trigger Xe release from Xe-ELIP, and endothelial cell permeability and cell viability were measured. Male Sprague-Dawley rats underwent right middle cerebral artery occlusion for 2 hours (n=28). In the treatment group (n=8), Xe-ELIP were administered through the right common carotid artery. Continuous ultrasound (0.22 MPa) was applied over the common carotid artery during the Xe-ELIP administration for 4 minutes. Infarct size as well as behavioral outcomes were determined 3 days after ...

Permanent-bilateral common carotid artery occlusion (P-BCCAO) in Wistar rat models are considered as accepted models for preclinical research on VD. It has been documented that the P-BCCAO rats undergo a brief period of acute severe ischemia immediately following P-BCCAO surgery. This offers a significant disadvantage in using this model to study chronic cerebral hypoperfusion induced VD in human beings. Moreover, the survival rate of this rat model is relatively low compared to other animal models being used for similar ...

To investigate the relationship between the elasticity of the carotid artery and the LV (left ventricle) systolic function in patients with diabetic nephropathy (DN) by using two-dimensional speckle-tracking strain echocardiography (2D-STE). DN patients (n = 108) and control subjects (n = 112), all of whom underwent echocardiography and carotid ultrasound. Analysis of LV GLS (global longitudinal strain) from the apical two-chamber (2C), three-chamber (3C), and four-chamber (4C) views. Meanwhile, the circumferential strain (CS) of the carotid artery was obtained from the view of the short-axis right common carotid artery. The differences between the two groups were compared, and a correlation analysis between CS and GLS was performed. The 4CGLS, 2CGLS, 3CGLS, and CS of the DN group were significantly lower at significant levels in contrast to the control group (p | 0.05). There was a significantly positive correlation of CS with 4CGLS, 2CGLS, and 3CGLS in all subjects (r = 0.809, p = 0.000; r = 0.830, p
misc{3051799, abstract = {Cardiovascular diseases, such as atherosclerosis, is a major cause of mortality in, primarily, the western world. To be able to recognize early symptoms of this type of diseases it has proven to be important to investigate the mechanical properties of blood vessels. A few years back from now it became evident that the common carotid artery has a distinct bidirectional movement pattern in the longitudinal direction during each cardiac cycle. The mechanisms of this behavior has however since then been undetermined. In this study three independent indicators of the cardiac wall movements involvement is presented. By ultrasound examinations of both the right and left side common carotids and simultaneous examinations of left ventricle movement of the heart of 14 humans it has become evident that: The longitudinal movement in the carotid arterial wall, in both directions, occurs in parts of the vessel close to the heart before it is transmitted to more peripheral parts of ...

Objective: People living with HIV (PLWH) have chronic immune activation and increased cardiovascular disease (CVD) risk. Activation of monocytes and T lymphocytes causes upregulation of glucose transporter-1 (GLUT1) for efficient function. PLWH have an increased percentage of GLUT1-expressing monocytes and T lymphocytes, but it is unclear if these cells are associated with CVD. We evaluated the expression of GLUT1 and CD38 on monocyte and T lymphocyte populations from HIVinfected women with subclinical CVD. Methods: Participants with more than 75th percentile (n-15) and less than 25th percentile (n=15) age-Adjusted intima-media thickness (IMT) at the right common carotid artery and bifurcation were identified from the Womens Interagency HIV Study. Groups were matched by age, race/ethnicity, smoking status, and CD4 cell count. All women were receiving suppressive antiretroviral therapy except for one high and one low IMT participant. Monocyte and T lymphocyte populations were evaluated for GLUT1 ...

Mammalian target of rapamycin (mTOR) has an important role in various biological processes in cells. In the present study, we investigated temporal changes in mTOR and phosphorylated-mTOR (p-mTOR) expressions in the rat hippocampal CA1 region following chronic cerebral hypoperfusion (CCH) induced by permanent bilateral common carotid arteries occlusion (2VO). The mTOR immunoreactivity in the pyramidal neurons and mTOR protein level in the hippocampal CA1 region were markedly decreased at 21 and 28 days after 2VO surgery. However, p-mTOR protein expression was significantly increased at 7 days following CCH but then decreased with time. The results indicate that mTOR and p-mTOR expressions change in the hippocampal CA1 region after 2VO surgery and that reduced expressions of mTOR and p-mTOR may be closely related to the CCH-induced neuronal damage in the hippocampal CA1 region ...
Hypoxia-ischemia (HI) is a major cause of brain damage in the newborn. Several studies elicited the neuroprotective effects of progesterone in adult rats but there is very little literature available on neonatal rats. Therefore the present study is undertaken to see the effect of progesterone in hypoxic ischemic brain injury in neonatal rats, using an established neonatal HI rat pup model. Seven-day-old rat pups were subjected to right common carotid artery ligation and then 60 minutes hypoxia. The first dose of progesterone to treatment group was administered by peritoneal injection (4 mg/kg), after 10 minutes of exposure and subsequent doses were given by subcutaneous injection at 6 h, 24 h and 48 h intervals. Control group was also exposed to HI and was given only the vehicle (peanut oil) through the same route and intervals as that of treatment group. After 96 h, the pups were perfused with 10% formalin and brains were sampled and stained with toluidine blue. Cells density and number of ...
Hypoxia-ischemia in 7-d-old rats. The Rice-Vannucci (Rice et al., 1981) neonatal adaptation of the Levine procedure (Levine, 1960) was used to cause hypoxic-ischemic brain injury in 7-d-old (p7) rats. In brief, rat pups were anesthetized with 2.5% halothane and 15% nitrous oxide in O2. The right common carotid artery was permanently ligated (in sham controls the ligature was passed around the artery and removed). After the wound was sutured, the pups recovered from anesthesia and were returned to the dam. Two hours later, pups were placed in an airtight container in a 37°C water bath through which humidified 8% O2and balance nitrogen flowed for 150 min. After hypoxia, pups were returned to the dam until death.. The animals were killed, and the brains were retrieved at 0, 1.5, 3, 6, and 24 hr after the end of hypoxia for histological analysis (n = 6 for each time point) or at 3, 6, and 24 hr after the end of hypoxia for Western blotting. Because of the small size of the immature rat thalamus, ...
THURSDAY, Oct. 11, 2018 (HealthDay News) - Common carotid artery (CCA) wall thickness measured using magnetic resonance imaging (MRI) is more consistently associated with incident cardiovascular disease (CVD) outcomes than intima-media thickness measured by ultrasound, according to a study published online Oct. 9 in Radiology.. Yiyi Zhang, Ph.D., from the Johns Hopkins University Bloomberg School of Public Health in Baltimore, and colleagues conducted a prospective study involving 698 participants without a history of clinical cardiovascular disease from the Multi-Ethnic Study of Atherosclerosis. CCA wall thickness was measured with ultrasound and with non-contrast proton density-weighted and intravenous gadolinium-enhanced MRI. The correlations between wall thickness measured with ultrasound and MRI were assessed with CVD outcomes.. The researchers found that per standard deviation increase in intima-media thickness, the adjusted hazard ratios for coronary heart disease, stroke, and CVD were ...

Introduction: Elevated levels of G protein-coupled receptor kinase 2 (GRK2) are associated with human hypertension and animal models of the disease. GRK2 is also increased in heart failure (HF). GRK2ct, a peptide inhibitor of GRK2 (last 194 amino acids of GRK2) is effective at rescuing models of HF through its restoration of cardiac βAR signaling.. Hypothesis: Our interest is in investigating the role of VSM GRK2ct to determine if it is an effective antihypertensive strategy.. Methods: We created transgenic mice that express the GRK2ct peptide in VSM using a portion of the SM22 promoter (VSM-GRK2ct). Conscious BP was derived using a fluid-filled indwelling left common carotid artery catheter. In vivo BP response to acute agonist infusion administered via the jugular vein was recorded in anesthetized mice. Vascular reactivity was determined by force displacement in aortic rings after mechanical endothelial cell denudation.. Results: RNA and protein levels verified VSM-specific expression in 2 ...
