Increased pressure stretches BLOOD VESSELS which activates the baroreceptors in the vessel walls. The net response of the CENTRAL NERVOUS SYSTEM is a reduction of central sympathetic outflow. This reduces blood pressure both by decreasing peripheral VASCULAR RESISTANCE and by lowering CARDIAC OUTPUT. Because the baroreceptors are tonically active, the baroreflex can compensate rapidly for both increases and decreases in blood pressure.Sodium Chloride, Dietary: Sodium chloride used in foods.Prospective Studies: Observation of a population for a sufficient number of persons over a sufficient number of years to generate incidence or mortality rates subsequent to the selection of the study group.Risk Factors: An aspect of personal behavior or lifestyle, environmental exposure, or inborn or inherited characteristic, which, on the basis of epidemiologic evidence, is known to be associated with a health-related condition considered important to prevent.Rats, Inbred WKY: A strain of Rattus norvegicus used as a normotensive control for the spontaneous hypertensive rats (SHR).Diet, Sodium-Restricted: A diet which contains very little sodium chloride.

Renin, an enzyme produced in the kidney, acts on angiotensinogen, an alpha-2 globulin produced by the liver, forming ANGIOTENSIN I. Angiotensin-converting enzyme, contained in the lung, acts on angiotensin I in the plasma converting it to ANGIOTENSIN II, an extremely powerful vasoconstrictor. Angiotensin II causes contraction of the arteriolar and renal VASCULAR SMOOTH MUSCLE, leading to retention of salt and water in the KIDNEY and increased arterial blood pressure. In addition, angiotensin II stimulates the release of ALDOSTERONE from the ADRENAL CORTEX, which in turn also increases salt and water retention in the kidney. Angiotensin-converting enzyme also breaks down BRADYKININ, a powerful vasodilator and component of the KALLIKREIN-KININ SYSTEM.Pressoreceptors: Receptors in the vascular system, particularly the aorta and carotid sinus, which are sensitive to stretch of the vessel walls.Follow-Up Studies: Studies in which individuals or populations are followed to assess the outcome of exposures, procedures, or effects of a characteristic, e.g., occurrence of disease.Central Venous Pressure: The blood pressure in the central large VEINS of the body.

It is used in the treatment of several disorders including edema, hypertension, diabetes insipidus, and hypoparathyroidism.Arteries: The vessels carrying blood away from the heart.Regression Analysis: Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.Rats, Sprague-Dawley: A strain of albino rat used widely for experimental purposes because of its calmness and ease of handling.

Effect of alcohol abstinence on blood pressure: assessment by 24-hour ambulatory blood pressure monitoring. (1/1099)

Several studies have shown that cessation of alcohol drinking reduces blood pressure (BP). However, attempts to reproduce these findings by ambulatory BP monitoring (ABPM) have shown inconsistent results. The aim of the present study was to assess the effect of 1 month of proven abstinence from alcohol on the 24-hour BP profile in heavy alcohol drinkers. Forty-two men who were heavy drinkers (>100 g of pure ethanol per day) were consecutively admitted to a general ward for voluntary alcohol detoxification. On the day of admission, they received a total dose of 2 g/kg of ethanol diluted in orange juice in 5 divided doses, and a 24-hour ABPM was performed. A new 24-hour BP monitoring in the same environmental conditions was performed after 1 month of proven alcohol abstinence while the subjects were receiving the same amount of fluid but without the addition of alcohol. After 1 month of proven alcohol abstinence, BP and heart rate (HR) significantly decreased. The reduction was 7.2 mm Hg for 24-hour systolic BP (SBP) (95% CI, 4.5 to 9.9), 6.6 mm Hg for 24-hour diastolic BP (DBP) (95% CI, 4.2 to 9.0), and 7.9 bpm for HR (95% CI, 5.1 to 10.7). The proportion of alcoholic patients considered hypertensive on the basis of 24-hour BP criteria (daytime SBP >/=135 mm Hg or daytime DBP >/=85 mm Hg) fell from 42% during alcohol drinking to 12% after 1 month of complete abstinence. Abstinence did not modify either the long-term BP variability, assessed by SD of 24-hour BP, or its circadian profile. We conclude that abstinence in heavy alcohol drinkers significantly reduces BP assessed by 24-hour ABPM and that this reduction is clinically relevant. These results show that heavy alcohol consumption has an important effect on BP, and thus cessation of alcohol consumption must be recommended as a priority for hypertensive alcohol drinkers.  (+info)

Alteration of circadian time structure of blood pressure caused by night shift schedule. (2/1099)

The effects of night shift schedules on circadian time structure of blood pressure were studied in seven healthy young subjects by continuous monitoring of blood pressure every 30 min for 72 h. In the control experiment, subjects were instructed to sleep at regular times with the light off at 00.00 h and the light on at 07.00 h. In the shift experiment, they were instructed to go to bed at 06.00 h and wake up at 11.00 h. The circadian rhythm of blood pressure rapidly phase delayed by 3.5 h in the second night shift day as a group phenomenon. Individual differences in changes in power spectral patterns of blood pressure were found in the night shift schedule. Ultradian rhythmicity of blood pressure was more pronounced in three subjects, whereas the circadian rhythmicity was maintained in four subjects. These findings held when the adaptation to shift work was taken into account.  (+info)

Ambulatory blood pressure monitoring and progression in patients with IgA nephropathy. (3/1099)

BACKGROUND: Hypertension is a recognized marker of poor prognosis in IgA nephropathy. METHODS: The present study investigated the prevalence of white-coat hypertension, the diurnal rhythm of blood pressure (BP), the effectiveness of antihypertensive drug therapy, and the effect of the above on the progression of the kidney disease in IgA nephropathy. One hundred twenty-six IgA nephropathy patients were selected consecutively for 24-h ambulatory blood pressure monitoring (ABPM). Fifty-five patients were normotensive and 71 were treated hypertensives. Their antihypertensive drugs were angiotensin-converting enzyme inhibitors (ACEI) alone or in combination with calcium-channel blockers (CCB). RESULTS: The mean night-time BP of normotensives (108+/-9/67+/-6 mmHg) was significantly lower than their day-time BP (125+/-8/82+/-7 mmHg, P<0.05). There was no significant difference between the mean day-time and night-time BP in hypertensive patients (125+/-9/82+/-7 mmHg vs 128+/-10/85+/-9 mmHg). The circadian variation of BP was preserved ('dippers') in 82% of the normotensive and 7% of the hypertensive patients (P<0.001). There were 10 'white-coat hypertensives' among the patients classified as normotensives with ABPM (mean office blood pressure 149+/-7/96+/-8 mmHg, 24-h blood pressure 127+/-6/83+/-5 mmHg, P<0.05) and 14 among treated hypertensives (mean office BP 152+/-8/98+/-6 mmHg, 24-h BP 130+/-4/85+/-8 mmHg, P<0.05). There was no difference in mean day-time BP among normotensive and treated hypertensive patients (125+/-8/81+/-5 mmHg vs 128+/-10/85+/-9 mmHg). Hypertensives had significantly higher night-time BP (125+/-9/85+/-9 mmHg) than normotensives (108+/-9/67+/-6 mmHg, P<0.001). There was no difference in serum creatinine levels among the different groups at the time of the ABPM. However, thirty-six+/-4.1 months after the ABPM, hypertensive patients (n=52) had higher serum creatinine levels (124+/-32 micromol/l) than at the time of the ABPM (101+/-28 micromol/l). The serum creatinine of normotensive patients (n=43) did not change during the follow-up period. 'Non-dipper' normotensives (n=10) had significantly higher serum creatinine levels at the end of the follow-up period than at its beginning (106+/-17 micromol/l vs 89+/-18 micromol/l, P<0.05). There was no increase in serum creatinine of 'dipper' normotensives. The mean serum creatinine of 'white-coat hypertensives' was significantly higher at the end of the study period than at its beginning. CONCLUSIONS: There is no diurnal blood pressure variation in most of the hypertensive IgA nephropathy patients. ACEI and CCB treatment have better effect on day-time than night-time hypertension. The lack of the circadian rhythm and 'white-coat hypertension' seems to accelerate the progression of IgA nephropathy.  (+info)

Effectiveness of 1,25-dihydroxyvitamin D supplementation on blood pressure reduction in a pseudohypoparathyroidism patient with high renin activity. (4/1099)

A 42-year-old man had biochemical and somatic abnormalities compatible with pseudohypoparathyroidism type I (PsHP) and also had high plasma renin activity (PRA). After 1,25-dihydroxyvitamin D (calcitriol) supplementation the systolic/diastolic blood pressure, assessed by 24-hour non-invasive ambulatory blood pressure monitoring, was reduced from 145/96 mm Hg to 128/85 mm Hg with normalization of the serum calcium level and its related hormones, as well as decreased PRA. Calcitriol supplementation successfully reduced the blood pressure in this patient with PsHP and a high PRA, suggesting that calcium-related hormones and/or the renin-angiotensin system were involved in lowering the blood pressure.  (+info)

Effects of coffee on ambulatory blood pressure in older men and women: A randomized controlled trial. (5/1099)

This study assessed the effects of regular coffee drinking on 24-hour ambulatory blood pressure (ABP) in normotensive and hypertensive older men and women. Twenty-two normotensive and 26 hypertensive, nonsmoking men and women, with a mean age of 72.1 years (range, 54 to 89 years), took part in the study. After 2 weeks of a caffeine-free diet, subjects were randomized to continue with the caffeine-free diet and abstain from caffeine-containing drinks or drink instant coffee (5 cups per day, equivalent to 300 mg caffeine per day) in addition to the caffeine-free diet for a further 2 weeks. Change in systolic and diastolic blood pressures (SBP, DBP) determined by 24-hour ambulatory BP monitoring showed significant interactions between coffee drinking and hypertension status. In the hypertensive group, rise in mean 24-hour SBP was greater by 4.8 (SEM, 1.3) mm Hg (P=0.031) and increase in mean 24-hour DBP was higher by 3.0 (1.0) mm Hg (P=0.010) in coffee drinkers than in abstainers. There were no significant differences between abstainers and coffee drinkers in the normotensive group for 24-hour, daytime, or nighttime SBP or DBP. In older men and women with treated or untreated hypertension, ABP increased in coffee drinkers and decreased in abstainers. Restriction of coffee intake may be beneficial in older hypertensive individuals.  (+info)

Effects of nisoldipine and lisinopril on left ventricular mass and function in diabetic nephropathy. (6/1099)

OBJECTIVE: To compare the effects of the calcium channel blocker, nisoldipine, and the ACE inhibitor, lisinopril, on left ventricular mass (LVM) and systolic function in type 1 diabetic patients with diabetic nephropathy. RESEARCH DESIGN AND METHODS: M-mode echocardiography was performed in 50 hypertensive type 1 diabetic patients with diabetic nephropathy enrolled in a 1-year, randomized, double-blind, parallel study of antihypertensive treatment with nisoldipine CC (20-40 mg/day) or lisinopril (10-20 mg/day). Ambulatory 24-h blood pressure was measured with the Takeda TM 2420 device (A & D, Tokyo, Japan) every 3 months. Three patients dropped out and seven patients were excluded due to technical difficulties. RESULTS: The 24-h diastolic blood pressure was reduced from 83 to 80 mmHg in the nisoldipine group (P = 0.06) and from 85 to 80 mmHg in the lisinopril group (P = 0.02). The decline in systolic blood pressure was not significant with any of the two treatments, and no difference in reduction of blood pressure was seen between groups. LVM corrected for body surface area (LVMI) was comparable between groups at baseline and increased from 96 +/- 5 to 107 +/- 6 g/m2 (mean +/- SEM; P = 0.007) in the nisoldipine group and from 95 +/- 4 to 103 +/- 5 g/m2 (P = 0.03) in the lisinopril group. The mean difference between the change in LVMI in the two groups was 2.9 (95% CI 6.8 to 12.7) g/m2. The prevalence of left ventricular hypertrophy rose from 18 (95% CI 6-30) to 30% (16-44) during the study period. A multiple linear regression analysis revealed that after 1 year of treatment, LVMI increased with higher systolic blood pressure level and declining glomerular filtration rate (R2 = 0.25). Fractional shortening was within normal range at baseline, 42 +/- 1 vs. 41 +/- 1% with nisoldipine and lisinopril, respectively, and did not change during follow-up. CONCLUSIONS: Antihypertensive treatment with nisoldipine or lisinopril to bring diastolic blood pressure level within the normal target range does not hinder a rise in LVMI in type 1 diabetic patients with diabetic nephropathy.  (+info)

G-Protein beta3 subunit C825T variant and ambulatory blood pressure in essential hypertension. (7/1099)

Recent studies have identified a novel polymorphism (C825T) of the gene encoding the beta3 subunit of heterotrimeric G proteins (Gbeta3) associated with enhanced activation of G proteins, which appears to be more common in hypertensive patients. In the present study we examine the relationship between this genetic variant and hypertension in 479 white patients with established essential hypertension recruited from the hypertension clinic of the Universitatsklinikum Benjamin Franklin in Berlin, Germany, and 1000 normotensive gender- and age-matched controls. All patients were screened for the presence of secondary hypertension and were further characterized by ambulatory blood pressure measurements performed in 295 treated and 184 untreated patients. Genotype distribution for the Gbeta3-C825T genotype in patients (CC=204, CT=224, TT=51) was significantly different from that in controls (CC=514, CT=412, TT=74; chi2=11.5, P<0.01), and the T allele was associated with an odds ratio of 1.5 (95% CI, 1.1 to 2.2) versus non-T carriers for the presence of hypertension. However, in both the whole group and the untreated subgroup, blood pressure levels between the genotypic groups were virtually identical. Furthermore, age of onset of hypertension and number of antihypertensive medications (in treated patients) were similar between the genotypic groups. Thus, while our data confirm the association between the Gbeta3-C825T variant and essential hypertension, they do not support the hypothesis that this marker is associated with more severe blood pressure in patients with already established hypertension.  (+info)

Ambulatory blood pressure and left ventricular mass in normotensive patients with autosomal dominant polycystic kidney disease. (8/1099)

Higher left ventricular mass (LVM) has been found in early stages of autosomal dominant polycystic kidney disease (ADPKD). The mechanisms involved in the increase of LVM are unknown. To investigate whether LVM in ADPKD may be influenced by abnormal diurnal BP variations, the 24-h ambulatory BP profile was analyzed in a group of young normotensive ADPKD patients. Ambulatory BP monitoring and two-dimensional echocardiography were performed in 26 young normotensive ADPKD with normal renal function and in 26 healthy control subjects. LVM index was higher in ADPKD patients than in controls (90.8+/-19.6 g/m2 versus 73.9+/-16.1 g/m2, P = 0.001). Average 24-h and daytime systolic, diastolic, and mean BP were similar in both groups. Nighttime diastolic and mean BP, but not systolic BP, were greater in ADPKD patients. The average and percent nocturnal decrease of systolic BP was lower in ADPKD patients than in control subjects (10.0 mm Hg [-3 to 24] versus 15.5 mm Hg [-4 to 31], P = 0.009, and 9.0% [-2 to 22] versus 14.2% [-2 to 25], P = 0.016, respectively). On the basis of their profile BP patterns, 54% of ADPKD subjects and 31% of controls were classified as nondippers (P = 0.092). There were no differences between dippers and nondippers in left ventricular wall thickness, chamber dimensions, and mass indexes. In ADPKD patients, simple regression analysis showed that LVM index was correlated with 24-h, daytime, and nighttime systolic BP. On multiple regression analysis, the 24-h systolic BP was the only variable linked to LVM index. It is concluded that young normotensive ADPKD patients have higher LVM that is closely related to the ambulatory systolic BP. The nocturnal fall in BP is attenuated in these patients, although it is not associated with the higher LVH that they present.  (+info)

Ambulatory blood pressure monitoring (ABPM) measures blood pressure at regular intervals. It is believed to be able to reduce the white coat hypertension effect in which a patients blood pressure is elevated during the examination process due to nervousness and anxiety caused by being in a clinical setting. Out-of-office measurements are highly recommended as an adjunct to office measurements by almost all hypertension organizations. 24-hour, non-invasive ambulatory blood pressure (BP) monitoring allows estimates of cardiac GFrisk factors including excessive BP variability or patterns of circadian variability known to increase risks of cardiovascular event. Ambulatory blood pressure monitoring allows blood pressure to be intermittently monitored during sleep, and is useful to determine whether the patient is a dipper or non-dipper-that is to say whether or not blood pressure falls at night compared to daytime values. A night time fall is normal and desirable. It correlates with relationship ...

Background: Hypertension is a major public health concern in Burkina Faso. Its management relies on in-office medical setting blood pressure monitoring which is known to be an imperfect diagnosis tool. Objective: This study aims to assess the contribution of ambulatory blood pressure monitoring in the management of hypertension at Blaise Compaoré University Hospital. Methods: A monocentric descriptive retrospective study was conducted in the cardiology outpatient unit of Blaise Compaoré University Hospital. Patients aged at least 18 years who underwent ambulatory blood pressure monitoring between March 2013 and June 2015 were enrolled. Hypertension was defined as follows: average blood pressure over 24 hours > 130/80 mmHg, or diurnal blood pressure > 135/85 mmHg, or nocturnal blood pressure >120/70 mmHg. Data were analyzed using the SPSS 20.0 software. The threshold for significance was set at 5% for a validity interval at 95%. Chi square test was used for the statistical analysis. Results: A total of

Background: Masked hypertension is associated with an increased risk of cardiovascular events, while white coat hypertension is considered to be a relatively lower risk condition; both are defined by the difference between awake ambulatory blood pressure (ABP) and office blood pressure (OBP). We review evidence on the relationship of this difference to age.. Method: We performed a systematic review of papers in PubMed using the combination of terms "office and ambulatory or home blood pressure (HBP)," and selected articles in which the OBP and awake ABP (or HBP) were presented. A random effects model was used for the meta-analyses.. Results: In the 18 studies of adults (N=8779), OBP was higher than awake ABP (the difference; 2.0±0.04/1.0±0.03 mmHg, both P,0.001); however, in the 5 studies of children and youth (N=1829), awake ABP was higher than OBP (7.9±0.12/7.9±0.10 mmHg, both P,0.001). In studies of general populations, OBP became higher than awake ABP after age 49.1/43.0 in women ...
Objective: To determine the relative accuracy of clinic measurements and home blood pressure monitoring compared with ambulatory blood pressure monitoring as a reference standard for the diagnosis of hypertension. Design: Systematic review with meta-analysis with hierarchical summary receiver operating characteristic models. Methodological quality was appraised, including evidence of validation of blood pressure measurement equipment. Data sources: Medline (from 1966), Embase (from 1980), Cochrane Database of Systematic Reviews, DARE, Medion, ARIF, and TRIP up to May 2010. Eligibility criteria for selecting studies: Eligible studies examined diagnosis of hypertension in adults of all ages using home and/or clinic blood pressure measurement compared with those made using ambulatory monitoring that clearly defined thresholds to diagnose hypertension. Results: The 20 eligible studies used various thresholds for the diagnosis of hypertension, and only seven studies (clinic) and three studies (home) could be
Introduction. Hypertension is a primary risk factor for cardiovascular and cerebrovascular diseases, and renal failure. It is well known that the quantity of dietary salt intake plays a role in the pathogenesis of primary hypertension. Increased sensitivity of blood pressure to excess sodium affects 50% of patients with primary hypertension.1,2 Dietary salt intake causes an increase in blood pressure, and is associated with renal and cardiovascular diseases, including left ventricular hypertrophy and microalbuminuria.3-5 Spontaneous variation in blood pressure is referred to as blood pressure variability (BPV), and is classified as short-term BPV and long-term BPV.6,7 Fluctuation during a 24-h period is referred to as short-term BPV and is based on 24-h ambulatory blood pressure monitoring (ABPM). Variation between successive ABPM measurements is known as average real variability (ARV), which is mathematically calculated.8,9 BPV was reported to be associated with hypertension-related target ...
BACKGROUND: Hypertension is a common complication and is an important risk factor for graft loss and adverse cardiovascular outcomes in pediatric kidney transplantation. Ambulatory blood pressure monitoring (ABPM) is the preferred method to characterize blood pressure status. METHODS: We conducted a retrospective review of a large cohort of children and young adults with kidney transplant to estimate the prevalence of abnormal ambulatory blood pressure (ABP), assess factors associated with abnormal ABP, and examine whether ambulatory hypertension is associated with worse allograft function and left ventricular hypertrophy (LVH). RESULTS: Two hundred twenty-one patients had ABPM, and 142 patients had echocardiographic results available for analysis. One third of the patients had masked hypertension, 32% had LVH, and 38% had estimated glomerular filtration rate less than 60 mL/min per 1.73 m. African-American race/Hispanic ethnicity and requirement for more than 1 antihypertensive medication were
This is a prospective randomized study with two arms: the Conventional and Ambulatory blood pressure monitoring arm and the Home blood pressure monitoring arm. The study will include both previously treated and untreated individuals.. Before randomization and in the end of the study, measurements will be performed using all three blood pressure monitoring methods (Conventional, Ambulatory and Home) as well as assessment of target organ damage (microalbuminuria, electrocardiogram, echocardiogram, carotid-femoral pulse wave velocity and central blood pressure).. The participants will be randomized into one of the two arms. Diagnosis and titration will be decided according to either Conventional and Ambulatory blood pressure measurements or according to Home blood pressure measurements. Subjects will be followed up for one year. ...
OBJECTIVES: This study was carried out to evaluate the effects of industrial noise on blood pressure and heart rate. METHODS: Resting blood pressure, hearing loss, and general characteristics of the 102 subjects who were engaged in a factory in Pusan were measured from March to June for two years, in 1998 and 1999. With noise dosimeter, noise exposure level was measured from 8 A.M. to 4 P.M. Ambulatory blood pressure and heart rate were also measured every 30 minutes from 8 A.M. to 10 P. M. RESULTS: Controlling for age, smoking, and Quetelets index, in subjects of under 40 years old exposed to higher than 85dBA, noise exposure and systolic blood pressure had a statistically significant correlation, and the same result was obtained in all subjects. The daily variability of ambulatory blood pressure and heart rate were observed in older than 40 years old group, but only heart rate in under 40 years old. CONCLUSIONS: The blood pressure and heart rate would be elevated when the workers exposed to ...
Upper limits of normal ambulatory blood pressure (ABP) have been a matter of debate in recent years. Current diagnostic thresholds for ABP rely mainly on statistical parameters derived from reference populations. Recent findings from the International Database of Ambulatory Blood Pressure in Relation to Cardiovascular Outcome (IDACO) provide outcome-driven thresholds for ABP Rounded systolic/diastolic thresholds for optimal ABP were found to be 115/75 mm Hg for 24 hours, 120/80 mm Hg for daytime, and 100/65 mm Hg for nighttime. The corresponding rounded thresholds for normal ABP were 125/75 mm Hg, 130/85 mm Hg, and 110/70 mm Hg, respectively, and those for ambulatory hypertension were 130/80 mm Hg, 140/85 mm Hg, and 120/70 mm Hg. However, in clinical practice, any diagnostic threshold for blood pressure needs to be assessed in the context of the patients overall risk profile. The IDACO database is therefore being updated with additional population cohorts to enable the construction of ...

Methods This was a secondary analysis of a randomized, controlled trial with allocation concealment and blinded outcome assessment in 134 patients with stable CHD and exercise-induced myocardial ischemia. Nighttime BP dipping was ...
An exception to this is those with very high blood pressure readings especially when there is poor organ function.[79] Initial assessment of the hypertensive people should include a complete history and physical examination. With the availability of 24-hour ambulatory blood pressure monitors and home blood pressure machines, the importance of not wrongly diagnosing those who have white coat hypertension has led to a change in protocols. In the United Kingdom, current best practice is to follow up a single raised clinic reading with ambulatory measurement, or less ideally with home blood pressure monitoring over the course of 7 days.[79] The United States Preventive Services Task Force also recommends getting measurements outside of the healthcare environment.[80] Pseudohypertension in the elderly or noncompressibility artery syndrome may also require consideration. This condition is believed to be due to calcification of the arteries resulting in abnormally high blood pressure readings with a ...

Hypertension is perhaps the most common reason for initiation of lifelong drug treatment and ongoing management by doctors. Six prospective studies have shown that ambulatory blood pressures may be a much better predictor of target organ damage and subsequent adverse events than measurements made in a clinic.1 As these results were found in research studies and mostly not in typical primary care settings, however, patients may have had a higher "alerting response" than in everyday settings with their family doctor or nurse. It is thus important to clarify whether the white coat effect applies equally outside a research study and in typical family practice settings.. Why is ambulatory monitoring not commonly used to make management decisions? The problem is not just extrapolating results from research or secondary care to routine settings but that clinic derived thresholds have been used in previous research to make treatment decisions. However, several lines of evidence show that patients with ...

The present study demonstrated that, in this hypertensive population without a history of cerebrovascular disease, the prevalence of microbleeds in the brain was 16.1% (95% CI, 11.1% to 21.0%), and that the daytime, nighttime, and 24-hour BP levels and a diagnosis of nocturnal hypertension were associated with the presence of BMBs, independent of age and sex, other cardiovascular risk factors, and coexisting ischemic brain damage.. The prevalence of BMBs in our hypertensive cohort is approximately 3 times higher than that reported in the general population.4 Importantly, in our study the microbleed-count could not have been influenced by a history of symptomatic cerebrovascular disease as this was an exclusion criterion.31,32 This, together with the observed associations between ambulatory BP and BMBs, suggests that hypertension is a substantial and independent risk factor for the development of BMBs.. The associations between the various ambulatory BP components and the presence of BMBs were ...

Nondipping nocturnal blood pressure, an independent cardiovascular risk factor (2), is closely associated with microalbuminuria regardless of usual blood pressure level. A recent study has shown that nondipping nocturnal blood pressure precedes microalbuminuria in normotensive diabetic patients (3). Thus, reduction of higher nocturnal blood pressure in normotensive diabetic patients with nondipping nocturnal blood pressure may have contributed to the reduction of urinary albumin excretion seen by Zandbergen and colleagues ...
Introduction 24-hour ambulatory blood pressure monitoring (ABPM) is the gold standard diagnostic method for hypertension, but has some shortcomings in clinical practice while clinical settings often lack sufficient devices to accommodate all patients with suspected hypertension. Home blood pressure monitoring (HBPM) and office blood pressure monitoring (OBPM) also have shortcomings, such as the white coat effect or a lack of accuracy. This study aims to study the validity of a new method of diagnosing hypertension consisting of monitoring blood pressure (BP) for 1 hour and comparing it with OBPM and HBPM and examining the sensitivity and specificity of this method compared with 24-hour ABPM. The patient experience will be examined in each method. Methods and analysis A minimum sample of 214 patients requiring a diagnostic test for hypertension from three urban primary healthcare centres will be included. Participants will undergo 24-hour ABPM, 1-hour BP measurement (1-BPM), OBPM for three ...
Results: Among participants not taking antihypertensive medication, the regression-derived thresholds for daytime, 24-hour, and nighttime SBP/DBP corresponding to clinic SBP/DBP of 140/90 mm Hg were 134/85 mm Hg, 130/81 mm Hg, and 123/73 mm Hg, respectively. The outcome-derived thresholds for daytime, 24-hour, and nighttime SBP corresponding to a clinic SBP ≥140 mm Hg were 138 mm Hg, 134 mm Hg, and 129 mm Hg, respectively. Among participants taking antihypertensive medication, the regression-derived thresholds for daytime, 24-hour, and nighttime SBP/DBP corresponding to clinic SBP/DBP of 140/90 mm Hg were 135/85 mm Hg, 133/82 mm Hg, and 128/76 mm Hg, respectively. The corresponding outcome-derived thresholds for daytime, 24-hour, and nighttime SBP were 140 mm Hg, 137 mm Hg, and 133 mm Hg, respectively, among those taking antihypertensive medication. ...

Background. N-terminal pro-brain natriuretic peptide (NT-proBNP) is considered a marker of poor cardiovascular prognosis in patients with diabetes1 . Increased resting heart rate is also associated with increased cardiovascular complications and mortality in patients with diabetes2 . There is evidence that BNP modulates the autonomic nervous system3 . This study aimed to investigate the relationship between NT-proBNP and 24h haemodynamic parameters in patients with type 1 and type 2 diabetes.. Methods. Clinical characteristics, serum NT-proBNP level and 24h ambulatory blood pressure were collected in 141patients with type 1 and type 2 diabetes who attended diabetes clinics at Austin Health, a tertiary referral centre in Melbourne. A multiple regression model was generated to predict log10(NT-proBNP), with the following variables as potential predictors: 24h systolic, diastolic and mean arterial blood pressure; morning blood pressure surge; night-to-day systolic blood pressure ratio; 24h heart ...

... (HBPM) offers many advantages. HBPM provides an average BP measurement over time, thus eliminating inadequate or misleading measurements that may be generated with in-office BP measurements. As with home blood glucose monitoring, HBPM has the potential to be incorporated into routine clinical care by patients with or at risk of hypertension. The committee recommended that HBPM should especially be considered in patients with newly diagnosed or suspected hypertension, in whom it might help to distinguish between white-coat and sustained hypertension.. Patient populations where HBPM also would be useful are seniors, children, and pregnant women, as well as patients with diabetes and/or kidney disease, as these types of populations are at increased risk for large variability in BP and white-coat hypertension. Furthermore, HBPM could be used to detect masked hypertension and is recommended for evaluating the response to antihypertensive therapy. Even with these ...

OBJECTIVE: To examine the relationship between 24-h blood pressure (BP) measurements, urinary albumin excretion rates, and autonomic neuropathy (AN) in adolescents with type 1 diabetes. RESEARCH DESIGN AND METHODS: A total of 31 patients with microalbuminuria (MA), 20 patients with intermittent MA (I-MA) and 11 patients with persistent MA (P-MA) were identified from the diabetes clinics at two major Australian tertiary care pediatric hospitals. Two control groups were used; one consisted of 19 age-, sex-, and diabetes duration-matched adolescents with normoalbuminuria (NA), and the other consisted of 46 age- and sex-matched nondiabetic control subjects. A medical history and physical examination were followed by a series of noninvasive tests of cardiovascular and pupillary autonomic function and then by 24-h ambulatory blood pressure monitoring (ABPM). RESULTS: ABPM showed an incremental increase in all BP parameters from nondiabetic control subjects through subjects with NA. A parallel ...

The Guidelines document also highlights another still unsolved issue related to the use of home blood pressure (1). These include the use of the approach in special populations, such as children, adolescents, elderly, pregnant women, obese patients, in which the lack of reference values for normality and/or technical difficulties in obtaining blood pressure measurements may make more difficult the use of this approach in the above mentioned conditions. This is also the case for cardiac arrhythmias (particularly atrial fibrillation) due to fact that the accuracy of the blood pressure measurement is lost or heavily impaired when an irregular or a chaotic cardiac rhythm is present ...

White coat hypertension, more commonly known as white coat syndrome, is a phenomenon in which patients exhibit a blood pressure level above the normal range, in a clinical setting, though they dont exhibit it in other settings. It is believed that the phenomenon is due to anxiety that those afflicted experience during a clinic visit. The patients daytime ambulatory blood pressure is used as a reference as it takes into account ordinary levels of daily stress. Many problems have been incurred in the diagnosis and treatment of white coat hypertension. The term "masked hypertension" can be used to describe the contrasting phenomenon, where a patients blood pressure is above the normal range during daily living, although it isnt above the normal range when the patient is in a clinic setting. In studies, white coat hypertension can be defined as the presence of a defined hypertensive average blood pressure in a clinic setting, although it isnt present when the patient is at home. Diagnosis is ...
An ambulatory blood pressure monitor is a small device that you wear throughout the day, usually for 24 or 48 hours. The device takes your blood pressure automatically while you do your normal daily activities.. The device periodically inflates and takes blood pressure measurements, which are recorded for later printout and analysis. The devices are usually loaned by a clinic, hospital, or pharmacy.. Your doctor might ask you to use one of these monitors after measuring your blood pressure in the doctors office, to make sure that you actually have high blood pressure. This is because your blood pressure can change during the day. And sometimes blood pressure is higher only because you are seeing a doctor. This is called white-coat hypertension. To diagnose high blood pressure, your doctor needs to know if your blood pressure stays high throughout the day. If you are required to use an ambulatory blood pressure monitor, keep in mind that it is important for a health professional to properly size ...
Epicardial fat tissue is known to have an unique endocrine function which affect the cardiac autonomic system. Heart rate recovery (HRR) is a simple non-invasive measurement that assesses autonomic nervous system dysfunction. We aimed to investigate the association among epicardial fat thickness (EFT), HRR and circadian blood pressure (BP) variation in patients with hypertension. A total of 358 consecutive patients who underwent both 24-hour ambulatory BP monitoring (ABPM) and a treadmill test were enrolled. Echocardiographic EFT and HRR, defined as peak heart rate minus heart rate after a 1-min recovery time, were measured. Patients were classified according to the ABPM; 147 patients with hypertension with a dipping pattern at night (dippers), 140 patients with hypertension with a non-dipping pattern at night (non-dippers) and 71 normotensive controls. EFT was significantly higher in hypertensive patients, especially in the non-dipper group, compared to the controls (non-dippers, 7.5 ± 2.9 mm; dippers

Despite the impressive increase of home blood pressure monitoring (BPM) among hypertensive patients over the last few years, a limited number of studies have analysed the rate of home BPM and its relationship with target blood pressure (BP) control, in representative samples of the hypertensive population. The objectives of the study were first to evaluate the prevalence of home BPM in a large selected group of treated hypertensive patients referred to our outpatient hypertension hospital clinic. Second, to assess the rate of satisfactory clinic BP control in patients with or without familiarity with home BPM. In all, 1350 consecutive hypertensive patients who attended our hypertension centre during a period of 12 months and were regularly followed up by the same medical team were included in the study. After informed consent all patients underwent the following procedures: (1) accurate medical history (implemented by a structured questionnaire on demographic and clinical characteristics, ...

Introduction 24-hour ambulatory blood pressure (BP) monitoring is a well-validated tool that can reveal the patients nocturnal dipping pattern. However, to the best of our knowledge, the role of home BP monitoring in identifying nocturnal dipping has not been studied. Methods We evaluated the nocturnal BP of 30 treatment-naive subjects using a home BP monitoring device. BP measurements were taken once during the daytime and once at night (three hours after sleep) by a blinded observer. Readings were correlated with left ventricular mass index. Results Night BP measurements were significantly lower in subjects without left ventricular hypertrophy (LVH) as compared to those with LVH, while the daytime readings were not significantly different between the two. The mean dips in nocturnal systolic and diastolic BP were 1.92% ± 6.89% and −0.55% ± 14.31%, respectively, in subjects with LVH. The corresponding values were 12.96% ± 6.16% and 11.36% ± 11.90% in those without LVH. The correlation ...

Monitoring your blood pressure at home used to be a rather tricky prospect for many people. Those who had arthritis couldnt squeeze the bulb used to pump up the pressure cuff, and those with hearing loss couldnt hear the heart sounds through the stethoscope. Even those with no physical problems had to learn the proper rate of cuff deflation and how to distinguish subtle heart sounds. Today, however, all of those problems have been solved by the development of digital monitors.. If youre using a fully automatic digital blood pressure monitor, all you have to do is position it on your arm and push a button. The cuff inflates and deflates automatically at the proper rate. Since the blood pressure is measured by an oscilloscope, theres no need to listen for heart sounds. The systolic and diastolic numbers are displayed on a small screen. Pulse rate is usually displayed as well. A semiautomatic digital monitor does everything except inflate the pressure cuff. Digital blood pressure monitors are ...

  • Classification of dipping in blood pressure is based on the American Heart Association's calculation, using systolic blood pressure (SBP) as follows: D i p = ( 1 − S B P S l e e p i n g S B P W a k i n g ) × 100 % {\displaystyle Dip=(1-{\frac {SBP_{Sleeping}}{SBP_{Waking}}})\times 100\%} Dippers have significantly lower all-cause mortality than non-dippers or reverse dippers. (wikipedia.org)
  • Dipping patterns are classified by the percent of drop in pressure, and based on the resulting ratios a person may be clinically classified for treatment as a "non-dipper" (with a blood pressure drop of less than 10%), a "dipper," an "extreme dipper," or a "reverse dipper," as detailed in the chart below. (wikipedia.org)
  • Moreover, increase in geriatric population, growth in demand of non-invasive devices for measuring blood pressure, and transformation from physician-centered to the patient-centered model fuel the market growth. (openpr.com)
  • The shift from physician-centered to patient-centered model and demand for a non-invasive way of measuring blood pressure are amplifying the market growth. (giiresearch.com)
  • Patient inertia, poor patient compliance, lack of medical consultation time, and poor patient access to a BP machine were the most common challenges for implementing out-of-office BP monitoring. (dovepress.com)
