    It is very important to maintain the level of mean arterial pressure (MAP).The MAP control is applied in many clinical situations,including limiting bleeding during cardiac surgery and promoting healing for patient's post-surgery.This paper presents a fuzzy controller-based multiple-model adaptive control system for postoperative blood pressure management.Multiple-model adaptive control (MMAC) algorithm is used to identify the patient model,and it is a feasible system identification method even in the presence of large noise.Fuzzy control (FC) method is used to design controller bank.Each fuzzy controller in the controller bank is in fact a nonlinear proportional-integral (PI) controller,whose proportional gain and integral gain are adjusted continuously according to error and rate of change of error of the plant output,resulting in better dynamic and stable control performance than the regular PI controller,especially when a nonlinear process is involved.For demonstration,a nonlinear,pulsatile-flow patient model is used for simulation,and the results show that the adaptive control system can effectively handle the changes in patient's dynamics and provide satisfactory performance in regulation of blood pressure of hypertension patients.

  3. Blood pressure control among type 2 diabetics

    International Nuclear Information System (INIS)

    Objective was to assess blood pressure BP control in patients with diabetes mellitus type 2 DM type treated in primary health care. A cross-sectional study was conducted in primary health care at King Fahd Military Complex Hospital in Dhahran, Kingdom of Saudi Arabia, between August 2003 and February 2004, to assess blood control in type 2 diabetics. A sample of 403 medical records of type 2 diabetic patients was selected using systematic random sampling after ordering the medical record numbers. The data were collected through the pre-coded checklist. Hypertension was found in 57.8% of diabetic patients with no statistically significant difference between males and females. The mean age of diabetic patients was significantly highly in hypertensive than non-hypertensive p=0.001. The mean duration of hypertension was significantly higher in females p=0.02. There were only 14.2% of hypertensive diabetic patients in whom blood pressure was controlled. Poor control was significantly associated with obesity and a high rate of complications. Blood pressure control correlated positively and significantly with the age of patients and negatively with duration of diabetes and hypertension. The most commonly prescribed antihypertensive were angiotensin converting enzyme inhibitors in 29.3%, followed by angiotensin receptors blockers in 24.1%, and the least prescribed drug was thiazide diuretic. Blood pressure in diabetic patients needs to be given particular attention from all health care professionals, especially primary care family physicians, who should follow the new guideline for better control of blood pressure, and fewer complications. Patient's awareness should be increased, through continuous health education with different modalities. (author)

    Both technological and human factors design requirements for integration of home blood pressure monitoring (HBPM) into a patient centered medical home (PCMH) model primary care practice are described. Patients with uncontrolled hypertension were given home blood pressure (BP) monitors, and after a three-month run-in period introduced to either a high-tech only (HBPM connectivity to personal health record and tailored Web portal access) or a high-tech/"high-touch" (high-tech solution plus patient navigator [PN]) solution. Features of the Web portal included: BP graphing function, traffic-light feedback system of BP goal attainment, economic incentives for self-monitoring, and dual patient-facing and care-team-facing dashboard functions. The e-health BP control system with PN support was well received by patients, providers, and the healthcare team. Current e-health technology and limited technological literacy of many patients suggest that a PN or some other personnel resource may be required for the adoption of patient-facing technology in primary care.

    Full Text Available Judith A WhitworthJohn Curtin School of Medical Research, Australian National University, Canberra, ACT, AustraliaAbstract: Two key early 20th century notions, the first the primacy of diastolic pressure in determining risk, and the second that hypertension is a discrete disorder, have proved to be incorrect. We now recognize the primacy of systolic pressure as a risk factor for cardiovascular disease and that hypertension is an arbitrary definition. In the early 21st century, we are moving away from a dichotomous approach to risk classification, and away from notions of hypertension and normotension towards an appreciation that blood pressure-related risk is continuous. In parallel, there has been a paradigm shift from a single risk factor approach to comprehensive cardiovascular disease risk prevention. Accordingly, prevention of cardiovascular disease requires a focus on lowering of blood pressure and modification of associated risk factors rather than simply treatment of hypertension. This emphasis is reflected in the World Health Organization (WHO – International Society of Hypertension (ISH 2003 statement on management of hypertension.Keywords: blood pressure, hypertension, cardiovascular risk, treatment

    Case of diabetes mellitus associated with essential hypertension are mostly type 2 diabetes mellitus(NIDDM) in elderly patients. In the JNC VI and JSH 2004, it is recommended that the therapeutic target blood pressure level should be lower then 130/80 mmHg in hypertension complicated with diabetes mellitus, and this target has recently obtained wide acceptance. On the other hand, the target blood pressure in elderly is recommended below 140/90 mmHg. Accordingly, diabetes mellitus in elderly hypertensives should be treated similarly as in the young and middle-aged. Because ACE inhibitors/ARBs or Ca blockers increase insulin sensitivity, these drugs should be used as the first choice in cases of elderly hypertensive patients complicated with diabetes mellitus.

    We use detrended fluctuation analysis (DFA) to study the dynamics of blood pressure oscillations and its feedback control in rats by analyzing systolic pressure time series before and after a surgical procedure that interrupts its control loop. We found, for each situation, a crossover between two scaling regions characterized by exponents that reflect the nature of the feedback control and its range of operation. In addition, we found evidence of adaptation in the dynamics of blood pressure regulation a few days after surgical disruption of its main feedback circuit. Based on the paradigm of antagonistic, bipartite (vagal and sympathetic) action of the central nerve system, we propose a simple model for pressure homeostasis as the balance between two nonlinear opposing forces, successfully reproducing the crossover observed in the DFA of actual pressure signals.

    There are major differences between the current knowledge of the treatment of cardiac conditions derived from evidence-based medicine and the widespread application of this knowledge. This is particularly true in the treatment of hypertension. Hypertension is the most common chronic cardiovascular condition, affecting more than 50 million Americans and approximately 1 billion individuals worldwide. However, many hypertensive patients are not receiving treatment, and of those that are, many are not adequately controlled. There is evidence that there are methods to improve blood pressure control and improve compliance with expert recommendations for the treatment of hypertension. These methods range from local initiatives such as academic detailing to national performance measures as have been developed by the US Department of Veterans Affairs. A challenge for the future will be to identify and broadly apply these and other programs to improve the quality and efficiency of hypertensive treatment. PMID:17319093

    Obesity and hypertension are growing epidemics in the modern world. Lifestyle changes and medical treatment for obesity have disappointing long-term results and albeit drugs for hypertension are usually very effective, the necessity of multiple pills and frequent side effects make the adherence to treatment a huge challenge for healthcare systems. Bariatric/metabolic surgery is a very effective treatment and an exponential number of studies have been showing its positive impact beyond weight loss, mainly on type 2 diabetes. There is also growing evidence suggesting that bariatric/metabolic surgery is associated with reduced incidence of cardiovascular events, but the impact on hypertension and other components of metabolic syndrome usually derive from trials' secondary end points. Taking this limitation in mind, bariatric/metabolic surgery action on blood pressure is reaching a significant proportion of hypertension resolution or improvement. In this review, we discussed the current evidence on the impact of bariatric/metabolic surgery on blood pressure control and pointed out perspectives in this research area. PMID:27324638

    Full Text Available Abstract Background Insufficient blood pressure control is a frequent problem despite the existence of effective treatment. Insufficient adherence to self-monitoring as well as to therapy is a common reason. Blood pressure self-measurement at home (Home Blood Pressure Measurement, HBPM has positive effects on treatment adherence and is helpful in achieving the target blood pressure. Only a few studies have investigated whether adherence to HBPM can be improved through simple measures resulting also in better blood pressure control. Objective Improvement of self-monitoring and improved blood pressure control by using a new colour-coded blood pressure diary. Outcome Primary outcome: Change in systolic and/or diastolic blood pressure 6 months after using the new colour-coded blood pressure diary. Secondary outcome: Adherence to blood pressure self-measurement (number of measurements/entries. Methods/Design Randomised controlled study. Population: 138 adult patients in primary care with uncontrolled hypertension despite therapy. The control group uses a conventional blood pressure diary; the intervention group uses the new colour-coded blood pressure diary (green, yellow, red according a traffic light system. Expected results/conclusion The visual separation and entries in three colour-coded areas reflecting risk (green: blood pressure in the target range ≤ 140/≤ 90 mmHg, yellow: blood pressure >140/>90 mmHg, red: blood pressure in danger zone > 180 mmHg/>110 mmHg lead to better self-monitoring compared with the conventional (non-colour-coded blood pressure booklet. The colour-coded, visualised information supports improved perception (awareness and interpretation of blood pressure and triggers correct behaviour, in the means of improved adherence to the recommended treatment as well as better communication between patients and doctors resulting in improved blood pressure control.

    Objective Our objective was to compare the clinical effectiveness of home blood pressure monitoring (HBPM) and 24-hour ambulatory blood pressure monitoring (ABPM) on blood pressure (BP) control and patient outcomes. Design A systematic review was conducted. We also appraised the methodological quality of studies. Data sources PubMed, Scopus, CINAHL, and the Cochrane Central Register of Control Trials (CENTRAL). Inclusion criteria Randomized control trials, prospective and retrospective cohort studies, observational studies, and case-control studies published in English from any year to present that describe HBPM and 24-hour ABPM and report on systolic and/or diastolic BP and/or heart attack, stroke, kidney failure and/or all-cause mortality for adult patients. Due to the nature of the question, studies with only untreated patients were not considered. Results Of 1,742 titles and abstractions independently reviewed by two reviewers, 137 studies met predetermined criteria for evaluation. Nineteen studies were identified as relevant and included in the paper. The common themes were that HBPM and ABPM correlated with cardiovascular events and mortality, and targeting HBPM or ABPM resulted in similar outcomes. Associations between BP measurement type and mortality differed by study population. Both the low sensitivity of office blood pressure monitoring (OBPM) to detect optimal BP control by ABPM and the added association of HBPM with cardiovascular mortality supported the routine use of HBPM in clinical practice. There was insufficient data to determine the benefit of using HBPM as a measurement standard for BP control. Conclusion HBPM encourages patient-centered care and improves BP control and patient outcomes. Given the limited number of studies with both HBPM and ABPM, these measurement types should be incorporated into the design of randomized clinical trials within hypertensive populations.

    Full Text Available Hernán TrimarchiDepartment of Medicine, Division of Nephrology, Hospital Británico de Buenos Aires, Buenos Aires, ArgentinaAbstract: Patients with chronic renal disease are at increased risk for the development of cardiovascular disease, which is the main cause of death in this growing population. Among the risk factors involved, hypertension and proteinuria are major contributors to kidney damage and, if not controlled, may eventually lead to the progression of renal failure and end-stage renal disease. Both proteinuria and hypertension can be primary pathologic events or can appear as complications of other disease processes. Initially, these two factors may operate separately but, as progression ensues, both processes generally combine, potentiating their effects and hastening renal damage. Therefore, strategies to reduce blood pressure and proteinuria are essential in order to slow the worsening of many nephropathies. Therapies that target the renin–angiotensin system offer particular benefit, as hypertension and proteinuria can be precisely reduced with angiotensin-converting enzyme inhibitors and/or angiotensin receptor blockers. However, with this intervention, plasma renin activity remains high, and although primary endpoints may be controlled, elevated renin concentration can contribute to cardiovascular damage. Aliskiren, a direct renin inhibitor, is the first example of a novel class of antihypertensive drugs with potent antiproteinuric effects, which, alone or combined, can contribute to delaying the progression of kidney disease.Keywords: aliskiren, proteinuria, hypertension, chronic kidney disease, renoprotection

The FDA website, as well as manufacturer prescribing information, was also reviewed to identify other relevant information.Results: Azilsartan is a new ARB with high affinity for the angiotensin 1 receptor, approved by the FDA for hypertension management. Unlike other ARBs, azilsartan has no clinical data supporting improvement in cardiovascular outcomes, and is not approved for indications other than hypertension, which a select few other ARBs may be used for (eg, diabetic nephropathy and heart failure. Chlorthalidone is a longer acting thiazide-like diuretic that has been demonstrated to improve cardiovascular outcomes. Combination treatment with azilsartan/chlorthalidone is effective for reducing blood pressure. Compared to olmesartan/hydrochlorothiazide and azilsartan/hydrochlorothiazide combinations, azilsartan/chlorthalidone appears to be more efficacious for reducing blood pressure.Conclusions: Azilsartan/chlorthalidone can be considered an antihypertensive therapy option in patients for whom combination therapy is required (blood pressure >20 mmHg systolic or

  17. Recurrence of lacunar stroke and blood pressure control. Kanagawa REALITY

    International Nuclear Information System (INIS)

    Information on the background and status of recurrence realities of lacunar infarction (LI) is still limited. We investigated 856 patients started to treat from 1997 to 2000, in whom a diagnosis of first-ever symptomatic LI was detected by MRI were enrolled, excluding possible cardiogenic embolic stroke or branch atheromatous disease using medical records in 14 institutions in Kanagawa, retrospectively. Recurrent cerebrovascular events (CVEs) occurred in 96 patients (11%) and the annual incidence was 4.8%. The mean systolic blood pressure (SBP) just before recurrence of CVEs was significantly higher than the mean SBP at final follow-up in recurrence-free patients (P<0.001). As the result of multivariate analysis performed after adjusting for following risk factors, antiplatelet therapy, a high SBP just before the end of follow-up, the presence of diabetes mellitus, and a modified Rankin scale≥5 were independent prognostic factors related to recurrence of CVEs. The recurrence rates of CVEs or LI were decreased by lowering of the SBP and diastolic blood pressure (DBP) just before the end of follow-up. Our analyses provide no evidence of a J-curve relationship between BP level and a recurrence after first-ever symptomatic LI. (author)

    The African American Study of Kidney Disease and Hypertension examined the effect on renal function decline of 2 blood pressure (BP) goals (low mean arterial pressure [MAP] disease (ESRD), death, or GFR decline by 50% or 25 mL/min per 1.73 m2. This report examines the effect of the BP intervention separately in the 3 drug groups. The BP effect was similar among the drug groups for either GFR slope or the main clinical composite. However, the BP effect differed significantly among the drug groups for the composite of ESRD or death (P=0.035) and ESRD alone (P=0.021). Higher event rates for amlodipine patients assigned to the usual BP goal (0.087 per patient-year for ESRD or death and 0.064 per patient-year for ESRD) were seen compared with the remaining groups of the factorial design (range, 0.041 to 0.050 for ESRD or death; and range, 0.027 to 0.036 for ESRD). The low BP goal was associated with reduced risk of ESRD or death (risk reduction 51%; 95% confidence interval, 13% to 73%) and ESRD (54%; 8% to 77%) for amlodipine patients, but not for patients assigned to the other drug groups. These secondary analyses suggest a benefit of the low BP goal among patients assigned to amlodipine, but they must be interpreted cautiously. PMID:15897360

  8. Neural Control of Blood Pressure in Chronic Intermittent Hypoxia.

    Shell, Brent; Faulk, Katelynn; Cunningham, J Thomas

    2016-03-01

    Sleep apnea (SA) is increasing in prevalence and is commonly comorbid with hypertension. Chronic intermittent hypoxia is used to model the arterial hypoxemia seen in SA, and through this paradigm, the mechanisms that underlie SA-induced hypertension are becoming clear. Cyclic hypoxic exposure during sleep chronically stimulates the carotid chemoreflexes, inducing sensory long-term facilitation, and drives sympathetic outflow from the hindbrain. The elevated sympathetic tone drives hypertension and renal sympathetic activity to the kidneys resulting in increased plasma renin activity and eventually angiotensin II (Ang II) peripherally. Upon waking, when respiration is normalized, the sympathetic activity does not diminish. This is partially because of adaptations leading to overactivation of the hindbrain regions controlling sympathetic outflow such as the nucleus tractus solitarius (NTS), and rostral ventrolateral medulla (RVLM). The sustained sympathetic activity is also due to enhanced synaptic signaling from the forebrain through the paraventricular nucleus (PVN). During the waking hours, when the chemoreceptors are not exposed to hypoxia, the forebrain circumventricular organs (CVOs) are stimulated by peripherally circulating Ang II from the elevated plasma renin activity. The CVOs and median preoptic nucleus chronically activate the PVN due to the Ang II signaling. All together, this leads to elevated nocturnal mean arterial pressure (MAP) as a response to hypoxemia, as well as inappropriately elevated diurnal MAP in response to maladaptations. PMID:26838032

    Failing to reach blood pressure (BP) goals is one of the main problems in hypertension management. Especially in high-risk patients, intensive monitoring including frequently office visits or new techniques to monitor home BP is required. A total of 60 patients with uncontrolled hypertension were included and randomized into a group with telemetric BP monitoring (TBPM) (n=30) and a control group receiving standard care (n=30). During the 3-month study period, patients received in addition to their antihypertensive pre-treatment up to 2 × 300 mg irbesartan to achieve the required target BP. All patients were instructed to measure their BP once daily in the morning. In the TBPM group automatic alerts were generated by the central database server using pre-defined algorithms and patients were subsequently contacted by the physician. At baseline mean 24-h ambulant BP monitoring (ABPM) was 143.3±11.1/82.6±9.9 mm Hg in the TBPM group and 141.4±12.6/82.1±6.5 mm Hg in the standard care group. During treatment mean systolic BP showed a more intensive decrease in the TBPM vs control group (-17.0±11.1 mm Hg vs -9.8±13.7 mm Hg; P=0.032). Patients in the TBPM group had a more pronounced night dipping and a higher reduction of mean pulse pressure than controls (-8.1±5.9 mm Hg vs -2.8±7.4 mm Hg, P=0.004). After 3 months, TBPM-treated patients were given a higher mean daily dose of irbesartan (375±187 mg vs 222±147 mg in controls; P=titration of the antihypertensive agent is possible. The alarm criteria chosen were useful to improve BP control. PMID:21228822

    2015-10-01

    Resuscitation of emergency care patients requires fast restoration of blood pressure to a target value to achieve hemodynamic stability and vital organ perfusion. A robust control design methodology is presented in this paper for regulating the blood pressure of hypotensive patients by means of the closed-loop administration of vasoactive drugs. To this end, a dynamic first-order delay model is utilised to describe the vasoactive drug response with varying parameters that represent intra-patient and inter-patient variability. The proposed framework consists of two components: first, an online model parameter estimation is carried out using a multiple-model extended Kalman-filter. Second, the estimated model parameters are used for continuously scheduling a robust linear parameter-varying (LPV) controller. The closed-loop behaviour is characterised by parameter-varying dynamic weights designed to regulate the mean arterial pressure to a target value. Experimental data of blood pressure response of anesthetised pigs to phenylephrine injection are used for validating the LPV blood pressure models. Simulation studies are provided to validate the online model estimation and the LPV blood pressure control using phenylephrine drug injection models representing patients showing sensitive, nominal and insensitive response to the drug.

    Obesity is accompanied by many severe complications including various cardiovascular disorders. An impairment of cardiovascular control by autonomic nervous system could be one of the possible links between obesity and cardiovascular complications development. The aim of this study was to compare spontaneous heart rate and systolic blood pressure oscillations reflecting cardiovascular autonomic control of young obese subjects with normal control subjects by linear and nonlinear methods and to find sensitive markers of early autonomic dysregulation. Continuous recordings of beat-to-beat systolic blood pressure and RR intervals from ECG were obtained from 40 obese subjects (25 female, age 14·2 [13·1-16·1] (median [interquartile range]) years) and gender and age matched non-obese control subjects. In addition to linear measures (time and frequency domain), we performed recurrence quantification analysis (RQA) and multiscale entropy analysis for both signals. While no significant differences in heart rate and systolic blood pressure dynamics were detected by linear measures and MSE, analysis of recurrence plots from RR intervals time series showed significant differences - indices trapping time and maximal length of vertical from RQA were significantly higher in obese compared to control group. We conclude that heart rate and blood pressure control by autonomic nervous system in young obese subjects is relatively well preserved. However, novel RQA-related measures are able to detect early subtle abnormalities in cardiac autonomic control in obese subjects indicating decreased signal complexity. PMID:25684329

    BACKGROUND: Although cupping remains a popular treatment modality worldwide, its efficacy for most diseases, including hypertension, has not been scientifical y evaluated. OBJECTIVE: We aimed to determine the efficacy of wet-cupping for high blood pressure, and the incidence of the procedure’s side effects in the intervention group. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This is a randomized control ed trial conducted in the General Practice Department at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, between May 2013 and February 2014. There were two groups (40 participants each):intervention group undergoing wet-cupping (hijama) in addition to conventional hypertension treatment, and a control group undergoing only conventional hypertension treatment. Three wet-cupping sessions were performed every other day. MAIN OUTCOME MEASURE: The mean systolic and diastolic blood pressures were measured using a validated automatic sphygmomanometer. The fol ow-up period was 8 weeks. RESULTS: Wet-cupping provided an immediate reduction of systolic blood pressure. After 4 weeks of fol ow-up, the mean systolic blood pressure in the intervention group was 8.4 mmHg less than in the control group (P = 0.046). After 8 weeks, there were no significant differences in blood pressures between the intervention and control groups. In this study, wet-cupping did not result in any serious side effects. CONCLUSION: Wet-cupping therapy is effective for reducing systolic blood pressure in hypertensive patients for up to 4 weeks, without serious side effects. Wet-cupping should be considered as a complementary hypertension treatment, and further studies are needed. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT01987583.

    Full Text Available Background: The poor control of blood pressure is one of the prevalent problems for primary health care services all over the world.Objective: The objective of this study was to evaluate blood pressure control in hypertensive patients. Method: We conducted a cross-sectional study that included 579 subjects representative of the hypertensive patient’s population in Sarvabad city, the west of Iran in 2011. This information was extracted from the family records. Adequate blood pressure control was defined as <140/90 mmHg.Results: The mean age was 65.8 years [95% CI: 64.8, 66.8], 38.7% were male, 9.8% were smokers and 18.3% were obese. Overall, 40% [95% CI: 35.9%, 44.1%] of hypertensive patients had their blood pressure controlled; the age-specific blood pressure control rate was 61.5%, 46.4% and 35.3% in men and 45.2%, 34% and 38.2% in women age 28 to 50 years, 51 to 70 years and above 71 years, respectively.After adjustment the likelihood of having poor control was 0.36 times greater among the diabetic patients, 0.52 times greater among the patients who had a BMI ≥ 30 that these were significant.Conclusion: In all, BP control rate was low (40%.These results suggest that the majority of the treated hypertensive patients are complicated with additional cardiovascular risk factors such as smoking and obesity therefore required a good management of BP control.

    Full Text Available Background: Systemic hypertension is highly prevalent and an important risk factor for cardiovascular events. Blood pressure control in hypertensive patients enrolled in the Hiperdia Program, a program of the Single Health System for the follow-up and monitoring of hypertensive patients, is still far below the desired level. Objective: To describe the epidemiological profile and to assess blood pressure control of patients enrolled in Hiperdia, in the city of Novo Hamburgo (State of Rio Grande do Sul, Brazil. Methods: Cross-sectional study with a stratified cluster random sample, including 383 adults enrolled in the Hiperdia Program of the 15 Basic Health Units of the city of Porto Alegre, conducted between 2010 and 2011. Controlled blood pressure was defined as ≤140 mmHg × 90 mmHg. The hypertensive patients were interviewed and their blood pressure was measured using a calibrated aneroid device. Prevalence ratios (PR with 95% confidence interval, Wald's χ2 test, and simple and multiple Poisson regression were used in the statistical analysis. Results: The mean age was 63 ± 10 years, and most of the patients were females belonging to social class C, with a low level of education, a sedentary lifestyle, and family history positive for systemic hypertension. Diabetes mellitus (DM was observed in 31%; adherence to the antihypertensive treatment in 54.3%; and 33.7% had their blood pressure controlled. DM was strongly associated with inadequate BP control, with only 15.7% of the diabetics showing BP considered as controlled. Conclusion: Even for hypertensive patients enrolled in the Hiperdia Program, BP control is not satisfactorily reached or sustained. Diabetic hypertensive patients show the most inappropriate BP control.

    Blood pressure is the force of blood against artery walls. It is measured in millimeters of mercury (mm Hg and recorded as two numbers: systolic pressure (as the heart contracts over diastolic pressure (as the heart relaxes between beats. High blood pressure (hypertension is defined as chronically elevated high blood pressure, with systolic blood pressure (SBP of 140 mm Hg or greater, and diastolic blood pressure (DBP of 90 mm Hg or greater. High blood pressure (HBP, smoking, abnormal blood lipid levels, obesity and diabetes are risk factors for coronary heart disease, the leading cause of death in the US. Lifestyle modifications such as engaging in regular physical activity, quitting smoking and eating a healthy diet (limiting intake of saturated fat and sodium and increasing consumption of fiber, fruits and vegetables are advocated for the prevention, treatment, and control of HBP. As multiple factors influence blood pressure, the effects of each factor are typically modest, particularly in normotensive subjects, yet the combined effects can be substantial. Nutrition plays an important role in influencing blood pressure. Orange juice should be included as part of any low sodium diet and/or any blood pressure reducing eating plan, as it is sodium free, fat-free and can help meet recommended levels of potassium intake that may contribute to lower BP.

    Full Text Available Carlos M Ferrario, Ronald D SmithWake Forest University School of Medicine, Winston-Salem, North Carolina, USAAbstract: Angiotensin receptor blockers have emerged as a first-line therapy in the management of hypertension and hypertension-related comorbidities. Since national and international guidelines have stressed the need to control blood pressure to <140/90 mmHg in uncomplicated hypertension and <130/80 mmHg in those with associated comorbidities such as diabetes or chronic kidney disease, these goal blood pressures can only be achieved through combination therapy. Of several drugs that can be effectively combined to attain the recommended blood pressure goals, fixed-dose combinations of angiotensin receptor blockers and the calcium channel blocker amlodipine provide additive antihypertensive effects associated with a safe profile and increased adherence to therapy. In this article, we review the evidence regarding the beneficial effects of renin–angiotensin system blockade with olmesartan medoxomil and amlodipine in terms of blood pressure control and improvement of vascular function and target organ damage.Keywords: amlodipine, angiotensin receptor blockers, angiotensin-converting enzyme 2, hypertension, renin–angiotensin system

    International Nuclear Information System (INIS)

    In anaesthetized cats, the nucleus tractus solitarii (NTS) and the locus coeruleus (LC) were bilaterally superfused through push-pull cannulae with artificial cerebrospinal fluid. Catecholamines were determined in the superfusate by a radioenzymatic assay, gamma-aminobutyric acid (GABA) was determined in the superfusate and homogenate with glutamate by an enzymatic and fluorimetric assay. In the NTS and LC the resting release of catecholamines varied rhythmically. To investigate the function of catecholaminergic neurons and GABAergic neurons of the NTS in cardiovascular control, the influence of experimentally induced blood pressure changes on the rates of release of the endogenous catecholamines dopamine, noradrenaline and adrenaline in the NTS was observed. The decreased noradrenaline and adrenaline release elicited by increases in blood pressure and the reduced release of dopamine induced by decreases in blood pressure suggest a hypertensive function of noradrenaline and adrenaline and a hypotensive role of dopamine at the level of the rostral and intermediate NTS. Bilateral carotid occlusion led to a very pronounced increase in the release rate of GABA in the rostral NTS. This result demonstrate the hypertensive function of GABA in the NTS. Thus underlining the importance of catecholaminergic and GABAergic neurons of the NTS in central cardiovascular control. The GABA-transaminase inhibitor Vigabatrin was injected wistar Kyoto rats and spontaneously hypertensive rats. GABA-Transaminase inhibition was accompanied by an increase of GABA concentration in the rat brain. The administration of Vigabatrin had no influence on the blood pressure but on the body wight of the rats. (Author)

    Full Text Available Abstract Background The GOOD (Global Cardiometabolic Risk Profile in Patients with Hypertension Disease survey showed that blood pressure control was significantly worse in hypertensive patients with metabolic syndrome and/or diabetes mellitus than in those with essential hypertension only. This analysis aimed to investigate which components of the metabolic syndrome are primarily associated with poor blood pressure control. Methods The GOOD survey was designed as an observational cross-sectional survey in 12 European countries to assess the cardiometabolic risk profile in patients with essential hypertension. Investigators were randomly selected from a list of general practitioners (70% of investigators and a list of specialists such as internists, cardiologists and hypertension specialists (30% of investigators. Data from 3,280 outpatients with hypertension, aged at least 30 years who were receiving antihypertensive treatment or had newly diagnosed hypertension according to the European Society of Hypertension and the European Society of Cardiology criteria, were included in the analyses. Blood pressure control, body mass index (BMI, waist circumference, serum triglycerides, total and high density lipoprotein (HDL cholesterol measurements were compared in patients with diabetes mellitus and metabolic syndrome, with diabetes mellitus only, with metabolic syndrome only, and with neither metabolic syndrome nor diabetes mellitus. Results The highest blood pressure values were found in patients with metabolic syndrome with or without diabetes mellitus. Blood pressure was significantly lower in patients with diabetes mellitus only. The highest BMI, waist circumference and serum triglycerides, and the lowest HDL cholesterol levels among the groups studied occurred in patients with metabolic syndrome, either with or without diabetes mellitus. Conclusion Among the components of the metabolic syndrome, it is not impaired glucose tolerance which is

    Blood pressure is the force of blood against artery walls. It is measured in millimeters of mercury (mm Hg) and recorded as two numbers: systolic pressure (as the heart contracts) over diastolic pressure (as the heart relaxes between beats). High blood pressure (hypertension) is defined as chronically elevated high blood pressure, with systolic blood pressure (SBP) of 140 mm Hg or greater, and diastolic blood pressure (DBP) of 90 mm Hg or greater.

    Full Text Available The purpose of the present study was to determine the range of the influence of the baroreflex on blood pressure in chronic renal hypertensive rats. Supramaximal electrical stimulation of the aortic depressor nerve and section of the baroreceptor nerves (sinoaortic denervation were used to obtain a global analysis of the baroreceptor-sympathetic reflex in normotensive control and in chronic (2 months 1-kidney, 1-clip hypertensive rats. The fall in blood pressure produced by electrical baroreceptor stimulation was greater in renal hypertensive rats than in normotensive controls (right nerve: -47 ± 8 vs -23 ± 4 mmHg; left nerve: -51 ± 7 vs -30 ± 4 mmHg; and both right and left nerves: -50 ± 8 vs -30 ± 4 mmHg; P < 0.05. Furthermore, the increase in blood pressure level produced by baroreceptor denervation in chronic renal hypertensive rats was similar to that observed in control animals 2-5 h (control: 163 ± 5 vs 121 ± 1 mmHg; 1K-1C: 203 ± 7 vs 170 ± 5 mmHg; P < 0.05 and 24 h (control: 149 ± 3 vs 121 ± 1 mmHg; 1K-1C: 198 ± 8 vs 170 ± 5 mmHg; P < 0.05 after sinoaortic denervation. Taken together, these data indicate that the central and peripheral components of the baroreflex are acting efficiently at higher arterial pressure in renal hypertensive rats when the aortic nerve is maximally stimulated or the activity is abolished.

    Objectives Most medical instruments are designed for diagnosis purpose but very few for clinical treatment. Our research aim is to design and develop a cardiovascular automatic feedback control instrument (CAFCI) for rescuing the critical patients with abnormal blood pressure.Methods The CAFCI was designed on the basis of abundant clinical experiences and on successful mathematic modeling of our experimental data. The blood pressure, pulmonary capillary wedge pressure,and rates of heart beat were measured and inputted into a computer and drugs were chosen by a doctor through a user-friendly interface with the computer.The responses to medication were rapidly acquired and feed back to the computer by automatic detection system in a close-loop system. The data were refreshed every 7.5 sec in order to regulate the speed and dosage of the medications that were given. Results The experimental results with ten dogs showed that the CAFCI system took samples promptly and accurately so that the targeted blood pressure could be reached reliably based on our input parameters and our designing requirements. Conclusions Since the dependability and accuracy of the CAFCI system are much superior to that of the traditional method, its clinical application to rescue the critical patient warrants evaluation in the future.

    Ambulatory blood pressure (ABP) monitoring provides unique information about day-night patterns of blood pressure (BP). The objectives of this article were to describe ABP patterns in African Americans with hypertensive kidney disease, to examine the joint distribution of clinic BP and ABP, and to determine associations of hypertensive target organ damage with clinic BP and ABP. This study is a cross-sectional analysis of baseline data from the African American Study of Kidney Disease Cohort Study. Masked hypertension was defined by elevated daytime (>or= 135/85 mm Hg) or elevated nighttime (>or= 120/70 mm Hg) ABP in those with controlled clinic BP (disease, in large part because of increased nighttime BP. Whether lowering nighttime BP improves clinical outcomes is unknown but should be tested given the substantial burden of BP-related morbidity in this population. PMID:19047584

    Background Several studies suggest that there is a pathogenic link between chronic obstructive pulmonary disease (COPD) and cardiovascular diseases. On the other hand, increased sympathetic tone has been described in several respiratory diseases. Our objective was to determine whether hypertension mediated by sympathetic overactivity is a mechanism that explains the association between COPD and cardiovascular diseases. Methods Prospective nested case-control observational study; 67 COPD patients were matched 1:1 by sex and age to controls with smoking history. 24 hour-blood pressure monitoring, urinary catecholamines and their metabolites measurement, echocardiography, carotid ultrasound examination, nocturnal oximetry and retinography were performed. Findings classic cardiovascular risk factors and comorbidities were similarly distributed between cases and controls. No significant differences for blood pressure variables (difference for mean systolic blood pressure: -0·13 mmHg; 95% CI: -4·48,4·20; p = 0·94; similar results for all blood presssure variables) or catecholamines values were found between both groups. There was a tendency for lower left ventricle ejection fraction in the COPD cases, that approached statistical significance (64·8 ± 7·4 vs 67·1 ± 6·2, p = 0·05). There were no differences in the retinal arteriovenous ratio, the carotid intima-media thickness, or the number of carotid plaques, between cases and controls. Fibrinogen values were higher in the COPD group (378·4 ± 69·6 vs 352·2 ± 45·6 mg/dL, p = 0·01) and mean nocturnal oxygen saturation values were lower for COPD patients (89·0 ± 4·07 vs 92·3 ± 2·2%, p COPD and cardiovascular disease.

    Full Text Available This paper aims to evaluate the comprehension of hypertensive patients of their condition and its management through health practices recognized by the Health Secretariat of the city of Curitiba and adopted in the Basic Health Unit .Vista Alegre.. The methodology used included collection of data about health actions promoted by the Unit, informal interviews with health professionals about how Hypertension Programs work and interviews based on a questionnaire with 50 patients participating in the Hypertension Program, selected and approached in the Health Unit or in household visits, who had their blood pressure taken after the interview. Thirty eight percent could not define hypertension, 72% assumed that nervousness or preoccupation were causes of hypertension, 84% mentioned stroke as consequence of high blood pressure, most of patients knew their medication and how to take it, 41% admitted forgetting to take their medication occasionally or often, 8% revealed not to take it correctly, 10% felt that not taking it sometimes does not make difference. Great part of those not taking their medication declared that this happens because they do not remember to take it, not for lacking it. Two thirds had unfavorable dietary habits and 52% did not engage in physical exercise but most believed that diet and exercise help controlling high blood pressure. Ninety six percent agreed that loosing weight also helps, but 72% were overweight. Only 13 (26% had normal blood pressure; 18% presented with severe hypertension and 20% with moderate hypertension. Analysis of the collected data showed that many patients are unable to define hypertension but know how to control it and are aware of its consequences. The excuses offered for not adapting to changes in their life stile were lack of time, stimulation and proof of benefits.

  8. Blood pressure variability and cardiovascular autonomic control during hemodialysis in peripheral vascular disease patients

    International Nuclear Information System (INIS)

    Hemodialysis (HD) patients with peripheral vascular disease (PVD) are at higher risk of mortality. The main objectives of this work were to investigate the hypothesis of an association between the PVD and an altered control system on peripheral resistance in response to volume depletion induced by HD treatment; and to investigate whether HD induced increase of pulse pressure (PP) is associated with PVD. Continuous blood pressure (BP) was recorded during HD treatment at the beginning and at the end of HD. The overhydration condition was evaluated by means of whole body bioimpedance spectroscopy, measured before each HD treatment. BP variability, heart rate variability and baroreflex sensitivity were then analyzed. Patients affected by PVD reported a prevalence of peripheral local control as shown by higher values of very low frequency in diastolic blood pressure (DBP) variability and a reduced cardiac baroreflex with respect to patients not affected by this pathology. HD treatment induced a significant increase of PP and LF% in DBP series in PVD patients only. Our results suggested that differences in BP variability and PP changes could be related not only to an underlying vascular disease, but also to an alteration in autonomic control. (paper)

Method The study was a patient-blinded randomized controlled trial conducted between February and May 2009 in Dangxiong County, Tibetan Autonomous Region, China. A total of 282 Tibetans aged 40 or older with known hypertension (systolic BP≥140 mmHg) were recruited and randomized to intervention (salt-substitute, 65% sodium chloride, 25% potassium chloride and 10% magnesium sulfate) or control (100% sodium chloride) in a 1: 1 allocation ratio with three months’ supply. Primary outcome was defined as the change in BP levels measured from baseline to followed-up with an automated sphygmomanometer. Per protocol (PP) and intention to treat (ITT) analyses were conducted. Results After the three months’ intervention period, the net reduction in SBP/DBP in the intervention group in comparison to the control group was −8.2/−3.4 mmHg (all p<0.05) in PP analysis, after adjusting for baseline BP and other variables. ITT analysis showed the net reduction in SBP/DBP at −7.6/−3.5 mmHg with multiple imputations (all p<0.05). Furthermore, the whole distribution of blood pressure showed an overall decline in SBP/DBP and the proportion of patients with BP under control (SBP/DBP<140 mmHg) was significantly higher in salt-substitute group in comparison to the regular salt group (19.2% vs. 8.8%, p = 0.027). Conclusion Low sodium high potassium salt-substitute is effective in lowering both systolic and diastolic blood pressure and offers a simple, low-cost approach for hypertension control among Tibetans in China.

Patients were categorized into well-controlled (controlled (140-160/90-100 mm Hg), and very poorly controlled (>160/100 mm Hg) groups according to their resting BP. The mean age[±standard error of the mean] of the patients was 68±13 years, and 885 (43.4%) were men. The prevalence of well-controlled hypertension (HTN) was 47.2%, poorly controlled HTN was 29.5%, and very poorly controlled HTN was 23.3%. Evidence of ischemia was seen in 19.8% and 19.3% of the well-controlled and poorly controlled groups, respectively. The very poorly controlled group had the lowest incidence of ischemia (14.3%) (Pcontrolled BP.

    Blood pressure maintenance is vital for systemic homeostasis, and angiotensin II is a critical regulator. The upstream mechanisms that regulate angiotensin II are not completely understood. Here, we show that angiotensin II is regulated by ERp44, a factor involved in disulfide bond formation in the ER. In mice, genetic loss of ERp44 destabilizes angiotensin II and causes hypotension. We show that ERp44 forms a mixed disulfide bond with ERAP1, an aminopeptidase that cleaves angiotensin II. ERp44 controls the release of ERAP1 in a redox-dependent manner to control blood pressure. Additionally, we found that systemic inflammation triggers ERAP1 retention in the ER to inhibit hypotension. These findings suggest that the ER redox state calibrates serum angiotensin II levels via regulation of the ERp44-ERAP1 complex. Our results reveal a link between ER function and normotension and implicate the ER redox state as a potential risk factor in the development of cardiovascular disease. PMID:25959394

    Full Text Available Monica Doménech, Antonio CocaHypertension Unit, Department of Internal Medicine, Institute of Internal Medicine and Dermatology, Hospital Clinic (IDIBAPS, University of Barcelona, SpainAbstract: Hypertension is one of the main risk factors for the development of cardiovascular diseases and the search for new therapeutic strategies aimed at optimizing its control remains an ongoing research and clinical challenge. In recent years, there has been a marked increase in the use of combinations of antihypertensive drugs with complementary mechanisms of action, with the aims of reducing blood pressure levels more rapidly and vigorously than strategies employing monotherapy and improving treatment compliance and adhesion. Therefore, as recommended by the 2009 reappraisal of the European Society of Hypertension/European Society of Cardiology Guidelines, the use of a triple combination that combines a calcium channel blocker, an angiotensin II receptor blocker and a thiazide diuretic seems a reasonable and efficacious combination for the management of hypertensive patients with moderate, high or very high risk. This article reviews the clinical trials carried out with the fixed combination of amlodipine/valsartan/hydrochlorothiazide at the doses recommended for each drug in monotherapy. The data show that this combination achieved greater reductions in mean sitting diastolic and systolic blood pressure than amlodipine, valsartan or hydrochlorothiazide in monotherapy, with favorable pharmacodynamic and pharmacokinetic profiles. The triple combination at high single doses should be used with caution in elderly patients and those with renal or liver failure. Although the tolerability and safety of the triple combination are good, the mostfrequently reported adverse effects were peripheral edema, headache and dizziness. Analytical alterations were consistent with the already-known biochemical effects of amlodipine, valsartan or hydrochlorothiazide in

The most available two-drug combinations have an agent that addresses renin secretion and another one that is statistically more effective in renin-independent hypertension. The practice of combining agents that counteract different mechanisms is the most likely explanation for the fact that most available two-drug combinations have an agent that addresses renin secretion (beta-blocker, angiotensin converting enzyme inhibitor, angiotensin II receptor blocker or direct renin inhibitor and another one that is more effective in renin-independent hypertension (diuretic, dihydropyridine or non-dihydropyridine calcium channel blocker. Based on these considerations, addition of hydrochlorothiazide to the combination of an antagonist of the renin-angiotensin system with a calcium channel blocker would constitute a logical approach. Inclusion of a diuretic in the triple combination is based on the evidence that these agents are effective and cheap, enhance the effect of other antihypertensive agents, and add a specific effect to individuals with salt-sensitivity of blood pressure. The benefit of triple combination therapy with amlodipine, valsartan and hydrochlorothiazide over its dual component therapies has been demonstrated, and the use of a single pill will simplify therapy resulting in better blood pressure control.Keywords: valsartan, amlodipine, hydrochlorothiazide, HCTZ, blood pressure, hypertension

    Full Text Available Background: With the increasing availability of Smartphones and wearable tracking devices, it is now feasible and affordable to apply such mobile devices to delivering mindfulness-based stress reduction (MBSR and intermittent fasting (IF to lower blood pressure, as traditional MBSR and IF incur the burden of commuting to the intervention sites for the patients. Our study will develop and scientifically evaluate an MBSR app, an IF app and an MBSR + IF app in terms of their effectiveness for lowering blood pressure. We will further explore the possible interaction effect (synergistic effect between MBSR and IF intervention: will improved mindfulness enhance patients’ adherence to the IF protocol? Methods: We will develop an MBSR app, an IF app, and an MBSR+IF app. We will then conduct an 8-week randomized controlled trial with a factorial design to evaluate the efficacy of these new apps, especially the interaction effect between MBSR and IF. Eligible individuals will be randomly assigned to Group 1 (MBSR app, Group 2 (IF app, Group 3 (MBSR + IF app or Group 4 (usual care. Discussion: This will be the first attempt to explore the impact of mindfulness intervention on the adherence of a behavioral intervention. Nevertheless, our protocol is limited in that the effectiveness of intermittent fasting on lowering blood pressure has not been supported by large-sample randomized controlled trials. Thus if there is no significant effectiveness we cannot determine whether it is due to the intermittent fasting intervention itself or it is due to the limit of smartphone as a vehicle.

    According to the Centers for Disease Control and Prevention (CDC), more than 65 million adults in America have hypertension (HTN) and fewer than half of those 65 million people have their blood pressure (BP) under control. More than 1,000 deaths occur each day related to HTN and Americans are at an increased risk of complications related to uncontrolled BP such as heart failure, stroke, myocardial infarction, and kidney disease (). Data from the National Home and Hospice Survey, which is conducted by the CDC, indicate that 41% of home care patients have HTN (). This research brief column profiles four recently published articles on HTN. The first discusses the most recent guidelines for managing HTN, which were released in early 2014. The second article describes the success of an intensive structured HTN medication management and management protocol. The third and fourth briefs describe studies investigating the ongoing risk of HTN poststroke. PMID:25370977

    2011-01-01

    Backgroud Numerous studies have confirmed the effectiveness of slowing the progression of atherosclerosis by blood pressure (Bp)control in patients with hypertension and several studies also showed the efficacy of intensive glycemic control in decreasing progression of carotid intima-media thickness (CIMT) in patients with type 1 and type 2 diabetes.However, few studies have compared the relative importance of glycemic vs.Bp control in patients with diabetes and hypertension.We aimed to investigate the association between Bp and glycemic control and subclinical carotid atherosclerosis in older patients with hypertension and type 2 diabetes.Methods In a cross-sectional study, B-mode high-resolution ultrasonography of the carotid artery was performed in 670 subjects (508 males and 162 females) aged 60 years or over who had self-reported hypertension and diabetes but no history of coronary heart disease or stroke.Subjects were categorized by their systolic blood pressure: tight control, < 130 mmHg; usual control, 130-139 mmHg; or uncontrolled, > 140 mmHg,and by their hemoglobin Alc (HbAlc) level: tight control, < 6.5%; usual control, 6.5%-7.5%; or uncontrolled, ≥ 7.5%, respectively.Results The mean CIMT was 8.20 ± 0.11 mm, and carotid plaque was found in 52.5% (352/670) subjects.Overall, 62.1% of the subjects had subclinical carotid atherosclerosis, defined as having either carotid plaque or elevated CIMT (≥1.1 mm).The mean CIMT was significantly different between Bp control categories (7.60 ± 0.09 mm, 7.90 ± 0.08 mm, and 8.60 ± 0.12 mm, respectively, P = 0.03) but not between glycemic control categories (8.20 ± 0.10 mm, 8.1 ± 0.08 mm, and 8.40 ± 0.14 mm, respectively, P = 0.13) using ANCOVA analysis.Multivariable logistic regression adjusting for potential confounding factors showed that usual or uncontrolled Bp control were associated with having carotid plaque (OR = 1.08 and OR = 1.42, respectively), or elevated CIMT [Odd ratio (OR) = 1

    Full Text Available BackgroundIn Georgia an estimated 32% of blacks and 28% of whites have high blood pressure. In 2004 the rate of death from stroke in Georgia was 12% higher than the national average, and blacks in the state have a 1.4 times greater rate of death from stroke than that of whites.ContextThe Georgia legislature funds the Stroke and Heart Attack Prevention Program (SHAPP to provide treatment and medications for indigent Georgians. The median rate of blood pressure (BP control among SHAPP enrollees is approximately 60%, compared with the national average of 35%.MethodsSHAPP was evaluated through interviews with key health care and administrative staff and through focus groups of patients in two clinics.ConsequencesOutcomes for patients were increased knowledge of their BP and improved compliance with taking medication and keeping clinic appointments.InterpretationSuccessful components of SHAPP include an easy enrollment process; affordable medication; use of evidence-based, documented protocols and patient tracking systems; routine follow-up of patients; and effective communication between staff and patients. Challenges and recommendations for improvement are identified.

    2010-10-01

    Nonadherence and poor or no persistence in taking antihypertensive medications results in uncontrolled high blood pressure, poor clinical outcomes, and preventable health care costs. Factors associated with nonadherence are multilevel and relate not only to the patient, but also to the provider, health care system, health care organization, and community. National guideline committees have called for more aggressive approaches to implement strategies known to improve adherence and technologies known to enable changes at the systems level, including improved communication among providers and patients. Improvements in adherence and persistence are likely to be achieved by supporting patient self-management, a team approach to patient care, technology-supported office practice systems, better methods to measure adherence, and less clinical inertia. Integrating high blood pressure control into health care policies that emphasize and improve prevention and management of chronic illness remains a challenge. Four strategies are proposed: focusing on clinical outcomes; empowering informed, activated patients; developing prepared proactive practice teams; and advocating for health care policy reform. With hypertension remaining the most common reason for office visits, the time is now. PMID:21029338

    Full Text Available AIM: To compare survival and incident cardiovascular disease between normotensive, untreated hypertensive, treated and poorly-controlled hypertensive and treated and well-controlled hypertensive adults. METHODS AND RESULTS: Data from the British Regional Heart Study (men and British Women's Heart and Health Study (women were used (N = 6476. Blood pressure and treatment were assessed at baseline (1998-2001 when participants were aged 60-79 years and participants were followed up for a median of 8 years. Date and cause of death were obtained from death certificates and non-fatal cardiovascular disease events were obtained from repeat detailed medical record reviews. Of the whole cohort 52% of women and 49% of men had untreated hypertension and a further 22% and 18%, respectively, had poorly treated hypertension. Just 3% of women and 4% of men had treated and well controlled hypertension and 23% and 29%, respectively, were normotensive. Compared to normotensive individuals, incident cardiovascular disease (fatal and non-fatal was increased in those with poorly-controlled hypertension (Hazard Ratio (HR: 1.88; 95%CI: 1.53, 2.30, those with untreated hypertension (HR 1.46; 95%CI 1.22, 1.75 and those who were well-controlled hypertension (HR 1.38; 95%CI 0.94, 2.03.

    Beyond the well-known effects on blood pressure (BP) of the dietary approaches to stop hypertension (DASH) and the Mediterranean diets, a large number of studies has investigated the possible BP lowering effect of different dietary supplements and nutraceuticals, the most part of them being antioxidant agents with a high tolerability and safety profile. In particular relatively large body of evidence support the use of potassium, L-arginine, vitamin C, cocoa flavonoids, beetroot juice, coenzyme Q10, controlled-release melatonin, and aged garlic extract. However there is a need for data about the long-term safety of a large part of the above discussed products. Moreover further clinical research is advisable to identify between the available active nutraceuticals those with the best cost-effectiveness and risk-benefit ratio for a large use in general population with low-added cardiovascular risk related to uncomplicated hypertension.

    We decided to determine the percentage of hypertensive patients whose blood pressure (BP) measurements were within recommended controlled range and to identify predictive factors for controlled BP. In this study carried out in 2014, 280 patients were included consecutively through sampling from both university and private medical centers/pharmacies in four Iranian cities. Demographic data as well as information about duration of HTN and prescribed medications, admission to emergency department (ED) because of HTN crisis, comorbidities, and control of HTN during the last 6 months by a healthcare provider were gathered. Adherence to anti-hypertensives was also determined using the validated Persian version of the 8-item Morisky Medication Adherence Scale (MMAS-8). Controlled BP was defined as systolic BPpersonnel (adjusted OR= 1.03, P= 0.04), and not having history of ED admission during the last 6 months because of HTN crisis (adjusted OR= 2.11, P= 0.01). Considerable number of the studied patients had uncontrolled BP. Regarding the dramatic consequences of uncontrolled high BP in long term, it is advisable that careful attention by health care providers to the aforementioned factors could raise the likelihood of achieving controlled BP.

    Job strain is a risk factor for hypertension, but it is not fully understood if components of job strain, or job demand or job control per se could be related to blood pressure (BP), and if so, whether the relationship differs between normotension and mildly elevated BP. We examined resting BP, and job stress components in 113 Japanese male hospital clerks (38.1 ± 4.4 yr). Subjects were classified into normotensive (NT) (<130/85 mmHg, n=83) and mildly elevated BP (ME) (≥130/85 mmHg) groups. Diastolic BP (DBP) showed a significant interaction between group and job control level (p=0.013). Subjects with low job control demonstrated higher DBP than those with high job control (89.1 ± 2.1 vs. 82.3 ± 2.3 mmHg, p=0.042) in ME group even after adjustments for covariates while DBP did not differ between low and high job control subjects in NT group. Systolic BP (SBP) did not differ between high and low job control subjects in both groups. Neither SBP nor DBP differed between high and low demand groups in either group. Among job strain components, job control may be independently related to BP in Japanese male workers with mildly elevated BP. PMID:25914072

    Full Text Available Abstract Background The coexistence of type 2 diabetes mellitus and hypertension increases the risk of cardiovascular diseases. The U.K. Prospective Diabetes Study has shown that blood pressure control as well as blood glucose control is efficient for prevention of complications in hypertensive patients with diabetes mellitus. However, some reports have shown that it is difficult to control the blood pressure and the concomitant use of a plurality of drugs is needed in hypertensive patients with diabetes mellitus. In recent years renin-angiotensin system depressants are increasingly used for the blood pressure control in diabetic patients. Particularly in Japan, angiotensin II (A II antagonists are increasingly used. However, there is no definite evidence of the point of which is efficient for the control, the increase in dose of A II antagonist or the concomitant use of another drug, in hypertensive patients whose blood pressure levels are inadequately controlled with A II antagonist. Methods/Design Hypertensive patients of age 20 years or over with type 2 diabetes mellitus who have been treated by the single use of AII antagonist at usual doses for at least 8 weeks or patients who have been treated by the concomitant use of AII antagonist and an antihypertensive drug other than calcium channel blockers and ACE inhibitors at usual doses for at least 8 weeks are included. Discussion We designed a multi-center, prospective, randomized, open label, blinded-endpoint trial, ADVANCED-J, to compare the increases in dose of A II antagonist and the concomitant use of a Ca-channel blocker (amlodipine and A II antagonist in hypertensive patients with diabetes mellitus, whose blood pressure levels were inadequately controlled with A II antagonist. This study is different from the usual previous studies in that home blood pressures are assessed as indicators of evaluation of blood pressure. The ADVANCED-J study may have much influence on selection of

    Full Text Available OBJECTIVE - To assess hypertension control rates in a specialized university-affiliated medical department, the influence of sex, diabetes, and obesity on that control, and the strategies for the treatment of hypertension. METHODS - We carried out a cross-sectional study with 1,210 patients followed up for at least 6 months. Information was gathered from medical and nursing records and comprised the following data: sex, age, weight, height, abdominal and hip circumferences, blood pressure, and class and number of the antihypertensive drugs prescribed. To assess obesity, we used body mass index and waist/hip ratio. Blood pressure was considered under control when its levels were below 140/90 mmHg. RESULTS - The study consisted of 73% females and 27% males. Most females (31.7% were 50 to 59 years of age, and most males (28.3% were 60 to 69 years. The blood pressure control rate found was 20.9% for the 1,210 patients and 23.4% for the hypertensive diabetic patients (n=290. Despite the low control rates found, 70% of the patients used 1 or 2 antihypertensive medications. A high prevalence of obesity (38% was observed, and females had a greater abdominal obesity index than males did (90% vs 82%, p<0.05. Patients with a greater body mass index had less control of blood pressure. CONCLUSION - The percentage of hypertensive patients with controlled blood pressure levels was low and was associated with a high prevalence of obesity. These data indicate the need for reviewing the strategies of global treatment for hypertension.

    Exposure to traffic-related air pollution is associated with risk of cardiovascular disease and mortality. We examined whether exposure to diesel exhaust increased blood pressure (BP) in human subjects. We analyzed data from 45 nonsmoking subjects, 18 to 49 years of age in double-blinded, crossover exposure studies, randomized to order. Each subject was exposed to diesel exhaust, maintained at 200 μg/m(3) of fine particulate matter, and filtered air for 120 minutes on days separated by ≥2 weeks. We measured BP pre-exposure, at 30-minute intervals during exposure, and 3, 5, 7, and 24 hours from exposure initiation and analyzed changes from pre-exposure values. Compared with filtered air, systolic BP increased at all of the points measured during and after diesel exhaust exposure; the mean effect peaked between 30 and 60 minutes after exposure initiation (3.8 mm Hg [95% CI: -0.4 to 8.0 mm Hg] and 5.1 mm Hg [95% CI: 0.7-9.5 mm Hg], respectively). Sex and metabolic syndrome did not modify this effect. Combining readings between 30 and 90 minutes, diesel exhaust exposure resulted in a 4.4-mm Hg increase in systolic BP, adjusted for participant characteristics and exposure perception (95% CI: 1.1-7.7 mm Hg; P=0.0009). There was no significant effect on heart rate or diastolic pressure. Diesel exhaust inhalation was associated with a rapid, measurable increase in systolic but not diastolic BP in young nonsmokers, independent of perception of exposure. This controlled trial in humans confirms findings from observational studies. The effect may be important on a population basis given the worldwide prevalence of exposure to traffic-related air pollution. PMID:22431582

    Full Text Available Giuseppe Derosa, Sibilla AT SalvadeoDepartment of Internal Medicine and Therapeutics, University of Pavia, Pavia, ItalyAbstract: Irbesartan, an angiotensin II type 1 receptor antagonist, is approved as monotherapy, or in combination with other drugs, for the treatment of hypertension in many countries worldwide. Data in the literature suggest that irbesartan is effective for reducing blood pressure over a 24-hour period with once-daily administration, and slows the progression of renal disease in patients with hypertension and type 2 diabetes. Furthermore, irbesartan shows a good safety and tolerability profile, compared with angiotensin II inhibitors and other angiotensin II type 1 receptor antagonists. Thus, irbesartan appears to be a useful treatment option for patients with hypertension, including those with type 2 diabetes and nephropathy. Irbesartan has an inhibitory effect on the pressor response to angiotensin II and improves arterial stiffness, vascular endothelial dysfunction, and inflammation in hypertensive patients. There has been considerable interest recently in the renoprotective effect of irbesartan, which appears to be independent of reductions in blood pressure. In particular, mounting data suggests that irbesartan improves endothelial function, oxidative stress, and inflammation in the kidneys. Recent studies have highlighted a possible role for irbesartan in improving coronary artery inflammation and vascular dysfunction. In this review we summarize and comment on the most important data available with regard to antihypertensive effect, endothelial function improvement, and cardiovascular risk reduction with irbesartan.Keywords: blood pressure, hypertension, endothelial function, irbesartan, antihypertensive drugs, combination therapy

    Full Text Available A slight reduction of blood pressure and heart rate can reduce the risk of developing cardiovascular disease. Maintenance of the respiratory rate within the normal range has also being identified as crucial for a healthy heart. Use of Indian and western music have been considered among many preventive programmes for long time in order to risk reduction associated with cardio vascular diseases. Therefore the aim of this study is to describe the effect of Indian classical music on systolic and diastolic blood pressure, pulse rate and respiratory rate in asymptomatic individuals aged 45 to 65 years. Methodology: A community based randomized intervention study was conducted in 252 asymptomatic individuals. The study group (n = 127 listened to a music based on Indian classical system (entire track of 22 minutes. The control group (n = 125 was kept silent for a similar time period. Systolic and diastolic blood pressure, pulse rate and respiratory rate of each study participant were monitored before and after the intervention. Results: Statistically significant reduction in systolic blood pressure (8.53 mmHg, diastolic blood pressure (5.8 mmHg, pulse rate (5.16 breaths per minute and respiratory rate (2.55 per minute were observed in the study group after listening to the music (p 0.05. The reduction was independent of gender, age, education level, practicing a mind relaxation technique and preferred type of music of the participant. Conclusions: Listening to Indian classical music for about 22 minutes significantly reduced systolic and diastolic blood pressure, pulse rate and respiratory rate of asymptomatic individuals. Hence, music may have a potential benefit in cardio vascular disease preventive programmes.

    Background The effect of fruit juice on serum cholesterol and blood pressure in humans has generated inconsistent results. We aimed to quantitatively evaluate the effect of fruit juice on serum cholesterol and blood pressure in adults. Methods We performed a strategic literature search of PubMed, EMBASE, and the Cochrane Library (updated to October, 2012) for randomized controlled trials that evaluated the effects of fruit juice on serum cholesterol and blood pressure. Study quality was assessed by using the Jadad scale. Weighted mean differences were calculated for net changes in cholesterol and blood pressure by using fixed-effects model. Prespecified subgroup and sensitivity analyses were conducted to explore the potential heterogeneity. Results Nineteen trials comprising a total of 618 subjects were included in this meta-analysis. Fruit juice consumption borderlinely reduced the diastolic blood pressure (DBP) by 2.07 mm Hg (95% CI: −3.75, −0.39 mm Hg; p = 0.02), but did not show significant effects on total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C) concentrations or systolic blood pressure (SBP) values. A significant reduction of TC concentration was observed in low-median intake of total polyphenols group. Subgroup analyses for HDL-C and LDL-C concentrations did not show statistically significant results. No significant heterogeneity was detected for all the measures. Conclusion This meta-analysis suggested that fruit juice had a borderline significant effect on reducing DBP, but had no effect on TC, HDL-C, LDL-C concentrations or SBP. PMID:23637831

    The Korotkoff approach is the only blood pressure (BP) measurement technique that allows contemporary data to be compared with decades of research. We randomly recruited 4483 people (53.3% women; mean age 52.1 years) from Gaoyou County, Jiangsu Province, China. Nine observers recorded the participants™ BP three times consecutively following Chinese Society of Hypertension guidelines. We assessed the BP phenotype based on five criteria: completeness of readings, percentage of identical BP readings, odd BP readings, end-digit preference and trends in BP from the first to the third reading. The proportion of participants with identical readings were 2.0% and 3.1% for systolic (SBP) and diastolic blood pressure (DBP), respectively. Among 26,898 BP values, 0.3% ended in an odd number. Among observers, the prevalence of identical readings varied from 0% to 5.3% for SBP and from 0% to 6.8% for DBP. Compared with the expected frequency of 20%, those ending in 0 had a lower frequency (17.2%; p < 0.001), whereas those ending in 8 had a higher frequency (22.4%; p < 0.001). From the first to the third measurement, SBP and DBP decreased (p < 0.001) by 0.87 and 0.55 mmHg, respectively. In conclusion, the procedures set up in the Gaoyou study produced a high-quality BP phenotype. PMID:26581308

    Blood pressure control remains a serious public health issue because hypertension is the most common risk factor for cardiovascular disease. Effective management of hypertension often requires lifestyle modification and medication adherence. The objective of this study was to identify the prevalence of blood pressure control, medication adherence, self-monitoring of blood pressure, depression, and exercise among workers with access to health resources. Faculty and staff (N = 484) from a university and health care institution in the southeastern United States participated in biometric and questionnaire screening. The researchers used initial screening data from this worksite wellness program to describe baseline blood pressure control (< 140/90 mm Hg), self-monitoring of blood pressure, medication adherence, depression, and exercise. Overall, 63% of the workers' blood pressure was controlled; however, 23% of the sample had been prescribed antihypertensive medication to control their blood pressure. Thirty percent of the sample reported practicing blood pressure self-monitoring, 72.2% reported that they exercised, and 22% reported feeling down and depressed. More than half (64.9%) who used prescribed antihypertensive medication reported adherence to these medications. PMID:25000548

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

    International Nuclear Information System (INIS)

    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 (ΔCHI), iCMI (ΔiCMI), and ER (ΔER) were evaluated. Mean blood volume in the common carotid artery (BF) and the decrease in BF per year (ΔBF) were also determined. The ΔCHI, ΔiCMI, and ΔER increased with age in the hypertensive subjects as well as the control group across all age groups evaluated. The ΔCHI, ΔiCMI, and ΔER were significantly greater in the patients with essential hypertension in their 50s as compared with the controls. In patients with essential hypertension aged 65 years or older, the ΔCHI, ΔiCMI, and ΔER 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 ΔCHI, ΔiCMI, and ΔER. The ΔCHI, ΔiCMI, and ΔER were significantly correlated with ΔBF 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.

    Full Text Available Howard TrachtmanDivision of Nephrology, Cohen Children's Medical Center of New York, Long Island Campus for the Albert Einstein College of Medicine, New Hyde Park, NY, USAAbstract: The incidence of hypertension is rising in the general population. A parallel trend is present in children and adolescents. This reflects more intensive treatment and improved patient survival after a wide range of serious systemic illnesses that can lead to hypertension. In addition, primary or essential hypertension is more prevalent because of the epidemic of obesity and metabolic syndrome in pediatric and adult patients of both genders and in all ethnic groups. As a consequence of the changing demographic pattern of hypertension, more patients are requiring therapy for elevated blood pressure. This review summarizes key aspects of the treatment for hypertension in pediatric patients and the long-term management of this problem, including nonpharmacologic strategies and drug treatment.Keywords: hypertension, pediatric, pharmacologic, renoprotection

    Background and Purpose While pharmacologic treatment of hypertension has important health benefits, it does not capture the benefit of maintenance of ideal health through the prevention or delay of hypertension. Methods 26,875 black and white participants aged 45+, were assessed and followed for incident stroke events. The association was assessed between incident stroke and: 1) systolic blood pressure categorized as normal (< 120 mmHg), prehypertension (120–139 mmHg), stage-1 hypertension (140–159 mmHg) and stage-2 hypertension (160 mmHg+), and 2) number of classes of antihypertensive medications, classified as none, 1, 2, or 3 or more. Results During 6.3 years of follow-up, 823 stroke events occurred. Nearly half (46%) of the population were successfully-treated (SBP < 140 mmHg) hypertensives. Within blood pressure strata, the risk of stroke increased with each additional class of required antihypertensive medication, with hazard ratio [HR]=1.33; 95%CI: 1.16–1.52 for normotensive, HR=1.15; 95%CI: 1.05–1.26 for prehypertension, and HR=1.22; 95%CI: 1.06–1.39 for stage 1 hypertension. A successfully treated (SBP<120 mmHg) hypertensive person on 3+ antihypertensive medication classes was at marginally higher stroke risk than a person with untreated stage 1 hypertension (HR=2.48 versus HR=2.19, relative to those with SBP <120 on no antihypertensive medications). Conclusions Maintaining the normotensive status solely through pharmacologic treatment has a profound impact, as nearly half of this general population cohort were treated to guideline (SBP<140 mmHg) but failed to return to risk levels similar to normotensive individuals. Even with successful treatment there is a substantial potential gain by prevention or delay of hypertension. PMID:25953369

St. Luke’s Episcopal Hospital/Texas Heart Institute, Houston, Texas, USAAbstract: Clevidipine is a new calcium channel blocker of the dihydropyridine class that is characterized by its ultra-short onset of action, vascular selectivity, small volume of distribution and extremely high clearance that coupled together result in an extremely short half-life of approximately 1 minute therefore permitting a rapid titration to the desired effect. Structurally similar to other dihydropyridines, clevidipine has an extra ester link that allows its rapid hydrolization to its inactive carboxylic acid metabolite in blood and extravascular tissues. Clevidipine’s metabolites are then primarily eliminated through urine and fecal pathways. Clevidipine does not affect cytochrome P450 (CYP enzymes and no clinically significant drug interactions have been determined. In trials like the ESCAPE trials, ECLIPSE, and VELOCITY, clevidipine demonstrated a significant improvement in the management of acute hypertension when compared to placebo as shown in both ESCAPE trials. The ECLIPSE trial compared clevidipine to other drugs currently used in the management of acute hypertension, such as sodium nitroprusside, nitroglycerine and nicardipine; clevidipine was superior to all three agents; in providing blood pressure support, safety and tolerability clevidipine also showed a significant reduction in mortality rate (4.7% vs 1.7%, P = 0.0445 when compared to sodium nitroprusside. In the VELOCITY trial clevidipine demonstrated a reduction in blood pressure of 6

  4. Night time blood pressure dip

    Institute of Scientific and Technical Information of China (English)

    Dennis; Bloomfield; Alex; Park

    2015-01-01

    The advent of ambulatory blood pressure monitoring permitted examination of blood pressures during sleep and recognition of the associated circadian fall in pressure during this period. The fall in pressure,called the "dip",is defined as the difference between daytime mean systolic pressure and nighttime mean systolic pressure expressed as a percentage of the day value. Ten percent to 20% is considered normal. Dips less than 10%,referred to as blunted or absent,have been considered as predicting an adverse cardiovascular event. This view and the broader concept that white coat hypertension itself is a forerunner of essential hypertension is disputable. This editorial questions whether mean arterial pressures over many hours accurately represent the systolic load,whether nighttime dipping varies from measure to measure or is a fixed phenomenon,whether the abrupt morning pressure rise is a risk factor or whether none of these issues are as important as the actual night time systolic blood pressure itself. The paper discusses the difference between medicated and nonmedicated white coat hypertensives in regard to the cardiovascular risk and suggests that further work is necessary to consider whether the quality and duration of sleep are important factors.

    Full Text Available Abstract Background In kidney transplant (Kt recipients , hypertension is a major risk for cardiovascular complications but also for graft failure. Blood pressure (BP control is therefore mandatory. Office BP (OBP remains frequently used for clinical decisions, however home BP (HBP have brought a significant improvement in the BP control. Sodium is a modifiable risk factor, many studies accounted for a decrease of BP with a sodium restricted diet. Increased potassium intake has been also recommended in hypertension management. Using an agreement between office and home BP, the present study investigated the relations between the BP control in Kt recipients and their urinary excretion and dietary consumption of sodium and potassium. Methods The BP control defined by OBP 30. Results Using an agreement between OBP and HBP, we identified controlled (21% and uncontrolled recipients (49%. Major confounding effects susceptible to interfere with the BP regulation did not differ between groups, the amounts of sodium excretion were similar (154 ± 93 vs 162 ± 88 mmol/24 h but uncontrolled patients excreted less potassium (68 ± 14 vs 54 ± 20 mmol/24 h; P = 0.029 and had significantly lower potassium intakes (3279 ± 753 vs 2208 ± 720 mg/24 h; P = 0.009, associated with a higher urinary Na+/K + ratio. Systolic HBP was inversely and significantly correlated to urinary potassium (r = −0.48; P = 0.002, a positive but non significant relation was observed with urinary sodium (r = 0,30;P = 0.074. Conclusions Half of the treated hypertensive Kt recipients remained uncontrolled in office and at home. Restoring a well-balanced sodium/potassium ratio intakes could be a non pharmacological opportunity to improve blood pressure control.

    We propose a dynamical model for mean inlet pressure estimation in an implantable rotary blood pump during the diastolic period. Non-invasive measurements of pump impeller rotational speed (ω), motor power (P), and pulse width modulation signal acquired from the pump controller were used as inputs to the model. The model was validated over a wide range of speed ramp studies, including (i) healthy (C1), variations in (ii) heart contractility (C2); (iii) afterload (C2, C3, C4), and (iv) preload (C5, C6, C7). Linear regression analysis between estimated and extracted mean inlet pressure obtained from in vivo animal data (greyhound dogs, N = 3) resulted in a highly significant correlation coefficients (R(2) = 0.957, 0.961, 0.958, 0.963, 0.940, 0.946, and 0.959) and mean absolute errors of (e = 1.604, 2.688, 3.667, 3.990, 2.791, 3.215, and 3.225 mmHg) during C1, C2, C3, C4, C5, C6, and C7, respectively. The proposed model was also used to design a controller to regulate mean diastolic pump inlet pressure using non-invasively measured ω and P. In the presence of model uncertainty, the controller was able to track and settle to the desired input within a finite number of sampling periods and minimal error (0.92 mmHg). The model developed herein will play a crucial role in developing a robust control system of the pump that detects and thus avoids undesired pumping states by regulating the inlet pressure within a predefined physiologically realistic limit.

    Huanhuan Hu

    Full Text Available The control of blood glucose levels, blood pressure (BP, and low-density lipoprotein cholesterol (LDL-C levels reduces the risk of diabetes complications; however, data are scarce on control status of these factors among workers with diabetes. The present study aimed to estimate the prevalence of participants with diabetes who meet glycated hemoglobin (HbA1c, BP, and LDL-C recommendations, and to investigate correlates of poor glycemic control in a large working population in Japan.The Japan Epidemiology Collaboration on Occupational Health (J-ECOH Study is an ongoing cohort investigation, consisting mainly of employees in large manufacturing companies. We conducted a cross-sectional analysis of 3,070 employees with diabetes (2,854 men and 216 women aged 20-69 years who attended periodic health examinations. BP was measured and recorded using different company protocols. Risk factor targets were defined using both American Diabetes Association (ADA guidelines (HbA1c < 7.0%, BP < 140/90 mmHg, and LDL-C < 100 mg/dL and Japan Diabetes Society (JDS guidelines (HbA1c < 7.0%, BP < 130/80 mmHg, and LDL-C < 120 mg/dL. Logistic regression models were used to explore correlates of poor glycemic control (defined as HbA1c ≥ 8.0%.The percentages of participants who met ADA (and JDS targets were 44.9% (44.9% for HbA1c, 76.6% (36.3% for BP, 27.1% (56.2% for LDL-C, and 11.2% (10.8% for simultaneous control of all three risk factors. Younger age, obesity, smoking, and uncontrolled dyslipidemia were associated with poor glycemic control. The adjusted odds ratio of poor glycemic control was 0.58 (95% confidence interval, 0.46-0.73 for participants with treated but uncontrolled hypertension, and 0.47 (0.33-0.66 for participants with treated and controlled hypertension, as compared with participants without hypertension. There was no significant difference in HbA1c levels between participants with treated but uncontrolled hypertension and those with treated and

    Background The plasma levels of cell-free DNA (cfDNA) are known to be elevated under inflammatory or apoptotic conditions. Increased cfDNA levels have been reported in hemodialysis (HD) patients. The aim of this study was to investigate the clinical significance of cfDNA in HD patients. Methods A total of 95 patients on HD were enrolled. We measured their predialysis cfDNA levels using real-time EIF2C1 gene sequence amplification and analyzed its association with certain clinical parameters. Results The mean plasma cfDNA level in the HD patients was 3,884 ± 407 GE/mL, and the mean plasma cfDNA level in the control group was 1,420 ± 121 GE/mL (P < 0.05). Diabetic patients showed higher plasma cfDNA levels compared with nondiabetic patients (P < 0.01). Patients with cardiovascular complications also showed higher plasma cfDNA levels compared with those without cardiovascular complication (P < 0.05). In univariable analysis, the cfDNA level was associated with 3-month mean systolic blood pressure (SBP), white blood cell, serum albumin, creatinine (Cr), normalized protein catabolic rate in HD patients. In diabetic patients, it was significantly correlated with SBP, hemoglobin A1c, and serum albumin. In multivariate analysis, SBP was the independent determinant for the cfDNA level. In diabetic patients, cfDNA level was independently associated with hemoglobin A1c and SBP. Conclusions In patients with HD, cfDNA is elevated in diabetic patients and patients with cardiovascular diseases. Uncontrolled hypertension and poor glycemic control are independent determinants for the elevated cfDNA. Our data suggest that cfDNA might be a marker of vascular injury rather than proinflammatory condition in HD patients. PMID:26779422

    Full Text Available BACKGROUND: The Mediterranean diet is a healthy diet with positive scientific evidence of preventing chronic diseases. Bioactive components support the healthy properties of the Mediterranean diet. Antioxidants and fiber, two components of the Mediterranean diet, are key functional nutrients for healthy eating and nutrition. Wine grape pomace is a rich source of these dietary constituents and may be beneficial for human health. Our hypothesis was that the intake of red wine grape pomace flour (WGPF prepared from red wine grapes (Cabernet Sauvignon variety reduced the metabolic syndrome in humans. To evaluate the effect of WGPF on components of metabolic syndrome we design a 16-week longitudinal intervention study. Thirty-eight males, 30-65 years of age, with at least one component of metabolic syndrome, were randomly assigned to either the intervention group (n = 25 or the control group (n = 13. At lunch, the intervention group was given 20 g of WGPF per day, which contained 10 g of dietary fiber, 822 mg of polyphenols and an antioxidant capacity of 7258 ORAC units. Both groups were asked to maintain their regular eating habits and lifestyles. Clinical evaluation, anthropometric measurements and biochemical blood analyses were done at the beginning and the end of the study. RESULTS: WGPF intake significantly decreased systolic and diastolic blood pressure as well as fasting glucose levels. Plasma γ-tocopherol and δ-tocopherol increased and carbonyl group in plasma protein decreased in WGPT group, significantly. No significant effect was observed for waist circumference, HDL cholesterol, triglycerides, total antioxidant capacity and vitamin C in and between groups. The group-dependent magnitude of the differences between the baseline and final postprandial insulin values and γ-tocopherol concentrations was statistically significant. CONCLUSIONS: The consumption of WGPF-rich in fiber and polyphenol antioxidants, as a food supplement in a

    Duc Anh Ha

    Full Text Available Cardiovascular disease (CVD is one of the leading causes of morbidity and mortality in Vietnam and hypertension (HTN is an important and prevalent risk factor for CVD in the adult Vietnamese population. Despite an increasing prevalence of HTN in this country, information about the awareness, treatment, and control of HTN is limited. The objectives of this study were to describe the prevalence, awareness, treatment, and control of HTN, and factors associated with these endpoints, in residents of a mountainous province in Vietnam.Data from 2,368 adults (age≥25 years participating in a population-based survey conducted in 2011 in Thai Nguyen province were analyzed. All eligible participants completed a structured questionnaire and were examined by community health workers using a standardized protocol.The overall prevalence of HTN in this population was 23%. Older age, male sex, and being overweight were associated with a higher odds of having HTN, while higher educational level was associated with a lower odds of having HTN. Among those with HTN, only 34% were aware of their condition, 43% of those who were aware they had HTN received treatment and, of these, 39% had their HTN controlled.Nearly one in four adults in Thai Nguyen is hypertensive, but far fewer are aware of this condition and even fewer have their blood pressure adequately controlled. Public health strategies increasing awareness of HTN in the community, as well as improvements in the treatment and control of HTN, remain needed to reduce the prevalence of HTN and related morbidity and mortality.

    2002-01-01

    Full Text Available A double-blind, randomized, placebo-controlled study was carried out on 44 hypertensive type 2 diabetic subjects previously treated by diet associated or not with sulfonylurea to assess the effects of acarbose-induced glycemic control on blood pressure (BP and hormonal parameters. Before randomization and after a 22-week treatment period (100 to 300 mg/day, the subjects were submitted to a standard meal test and to 24-h ambulatory BP monitoring (ABPM and had plasma glucose, glycosylated hemoglobin, lipid profile, insulin, proinsulin and leptin levels determined. Weight loss was found only in the acarbose-treated group (75.1 ± 11.6 to 73.1 ± 11.6 kg, P<0.01. Glycosylated hemoglobin decreased only in the acarbose group (6.4 ± 1.7 to 5.6 ± 1.9%, P<0.05. Fasting proinsulin decreased only in the acarbose group (23.4 ± 19.3 to 14.3 ± 13.6 pmol/l, P<0.05, while leptin decreased in both (placebo group: 26.3 ± 6.1 to 23.3 ± 9.4 and acarbose group: 25.0 ± 5.5 to 22.7 ± 7.9 ng/ml, P<0.05. When the subset of acarbose-treated patients who improved glycemic control was considered, significant reductions in diurnal systolic, diastolic and mean BP (102.3 ± 6.0 to 99.0 ± 6.6 mmHg, P<0.05 were found. Acarbose monotherapy or combined with sulfonylurea was effective in improving glycemic control in hypertensive diabetic patients. Acarbose-induced improvement in metabolic control may reduce BP in these patients. Our data did not suggest a direct action of acarbose on insulin resistance or leptin levels.

  15. Personal Continuity of Care in a University-Based Primary Care Practice: Impact on Blood Pressure Control.

    Directory of Open Access Journals (Sweden)

    Nik Sherina Hanafi

    Full Text Available Continuity of care is an important quality outcome of patient care. This study aimed to investigate the relationship between personal continuity and blood pressure (BP control among the patients with hypertension in an academic primary care centre. Between January and May 2012, we conducted a retrospective review of medical records of patients with hypertension who had been followed up for at least 1 year in the Primary Care Clinic, University of Malaya Medical Centre, Malaysia. In this setting, doctors who provided care for hypertension included postgraduate family medicine trainees, non-trainee doctors and academic staff. Systematic random sampling (1:4 was used for patient selection. BP control was defined as less than 130/80 mm Hg for patients with diabetes mellitus, proteinuria and chronic kidney disease and less than 140/90 mm Hg for all other patients. Continuity of care was assessed using the usual provider continuity index (UPCI, which is the ratio of patient visits to the usual provider to the total number of visits to all providers in 1 year. A UPC index of zero denotes no continuity while an index of one reflects perfect continuity with only the usual provider. We reviewed a total of 1060 medical records. The patients' mean age was 62.0 years (SD 10.4. The majority was women (59.2% and married (85.7%. The mean number of visits in a year was 3.85 (SD 1.36. A total of 72 doctors had provided consultations (55 postgraduate family medicine trainees, 8 non-trainee doctors and 9 academic staff. The mean UPCI was 0.43 (SD 0.34. Target BP was achieved in 42% of the patients. There was no significant relationship between BP control and personal continuity after adjustment for total number of visits. Continuity of care was not associated with BP control in our centre. Further studies are needed to explore the reasons for this.

    Hypertension is a major risk factor for developing cardiovascular disease, stroke, and kidney disease. To lower blood pressure (BP), several lifestyle changes are recommended such as weight loss, exercise, and following a healthy diet. Investigating the effect of single nutrients may have positive results, but food is consumed as part of a whole diet, resulting in nutrient interactions. The aim of this systematic review and meta-analysis was to assess the effect of dietary patterns on BP in adults. Studies that were published between January 1999 and June 2014 were retrieved using Scopus, Web of Science, and the MEDLINE database. Seventeen randomized controlled trials were included in the meta-analysis. The results suggest that healthy dietary patterns such as the Dietary Approaches to Stop Hypertension diet, Nordic diet, and Mediterranean diet significantly lowered systolic BP and diastolic BP by 4.26 mm Hg and 2.38 mm Hg, respectively. These diets are rich in fruit, vegetables, whole grains, legumes, seeds, nuts, fish, and dairy and low in meat, sweets, and alcohol. Lifestyle factors such as exercise and weight loss in combination with dietary changes may also reduce BP. Further research is needed to establish the effect of dietary patterns on BP in different cultures other than those identified in this review. The review was registered on PROSPERO (International prospective register of systematic reviews) as CRD42015016272. PMID:26773016

    Full Text Available Systemic arterial blood pressures were measured in 30 dogs with acute babesiosis, 10 each with mild uncomplicated, severe uncomplicated and complicated disease. Ten healthy dogs were used as controls. Hypotension was defined as more than 3 standard deviations below the control mean. Normal mean pressures (±SD were: systolic arterial pressure 151 (±11 mm Hg, diastolic arterial pressure 89 (±8 mm Hg and mean arterial pressure 107 (±10 mmHg. Hypotension was the most frequent abnormality, and increased strikingly in incidence as disease severity increased, with 5/10 dogs in the complicated group being hypotensive for systolic, diastolic and mean arterial pressures, compared with 2/10 in the severe uncomplicated group and 0/10 in the mild uncomplicated group. Systolic, diastolic and mean arterial pressures in the complicated group and severe uncomplicated group, and systolic pressure in the mild uncomplicated group, were significantly lower than in the controls. There were no significant relationships between arterial pressures and age, pulse rate, respiratory rate, temperature, mucous membrane colour or haematocrit. There was a significant negative correlation between arterial pressures and white cell and immature neutrophil counts. Arterial pressures differed significantly between dogs that were clinically collapsed and those that were not, but not between survivors and non-survivors. Pulse pressure (systolic - diastolic was low in 7/10 complicated, 1/10 mild uncomplicated, and 1/10 severe uncomplicated cases, and differed significantly between the complicated and control groups. The high incidence of hypotension in clinically severe babesiosis has important implications for therapy.

    Full Text Available Background: More attention is being paid lately to polycystic ovary syndrome (PCOS not only in the aspect of fertility but also according to long-term metabolic and cardiovascular abnormalities. Observations of women with PCOS show that the occurrence of blood hypertension is more frequent after the menopause. There are few articles concerning the predictable symptoms of blood hypertension. It seems that twenty-four hour blood pressure monitoring and assessment of changes of diurnal rhythm could be useful in this group of patients.Aim of the study: The purpose of this study was to assess diurnal changes of blood pressure in women with polycystic ovary syndrome.Material and methods: 26 women with PCOS diagnosed according to Rotterdam consensus criteria and Androgen Excess Society (AES criteria were included in our study. The mean age of the examined women was 29.5 years and the mean BMI (body mass index was 24.7 kg/m2. The control group consisted of 12 age-matched women, without PCOS. Twenty-four hour Holter monitoring of ambulatory blood pressure was performed during normal daily activity in all patients. Halberg’s cosinor method was used to analyse daily biorhythm.Results: Results show the diurnal changes of systolic blood pressure in the preclinical phase in 30% and diastolic in 15% of PCOS women. In this group no physiological decrease of blood pressure at night time was observed.

    Full Text Available Abstract Background Prediabetes (PreDM in asymptomatic adults is associated with abnormal circadian blood pressure variability (abnormal CBPV. Hypothesis Systemic inflammation and glycemia influence circadian blood pressure variability. Methods Dahl salt-sensitive (S rats (n = 19 after weaning were fed either an American (AD or a standard (SD diet. The AD (high-glycemic-index, high-fat simulated customary human diet, provided daily overabundant calories which over time lead to body weight gain. The SD (low-glycemic-index, low-fat mirrored desirable balanced human diet for maintaining body weight. Body weight and serum concentrations for fasting glucose (FG, adipokines (leptin and adiponectin, and proinflammatory cytokines [monocyte chemoattractant protein-1 (MCP-1 and tumor necrosis factor-α (TNF-α] were measured. Rats were surgically implanted with C40 transmitters and blood pressure (BP-both systolic; SBP and diastolic; DBP and heart rate (HR were recorded by telemetry every 5 minutes during both sleep (day and active (night periods. Pulse pressure (PP was calculated (PP = SBP-DBP. Results [mean(SEM]: The AD fed group displayed significant increase in body weight (after 90 days; p Conclusion These data validate our stated hypothesis that systemic inflammation and glycemia influence circadian blood pressure variability. This study, for the first time, demonstrates a cause and effect relationship between caloric excess, enhanced systemic inflammation, dysglycemia, loss of blood pressure control and abnormal CBPV. Our results provide the fundamental basis for examining the relationship between dysglycemia and perturbation of the underlying mechanisms (adipose tissue dysfunction induced local and systemic inflammation, insulin resistance and alteration of adipose tissue precursors for the renin-aldosterone-angiotensin system which generate abnormal CBPV.

    2007-01-01

    Full Text Available Abstract Background Dietary calcium intake and the renin angiotensin system (RAS regulate blood pressure (BP by modulating calcium homeostasis. Despite similar BP regulatory effects, the influence of dietary calcium intake alone and combined with RAS polymorphisms on the BP response following acute aerobic exercise (i.e., postexercise hypotension has not been studied. Thus, we examined the effect of dietary calcium intake and selected RAS polymorphisms on postexercise hypotension. Methods Subjects were men (n = 50, 43.8 ± 1.3 yr with high BP (145.3 ± 1.5/85.9 ± 1.1 mm Hg. They completed three experiments: non-exercise control and two cycle bouts at 40% and 60% of maximal oxygen consumption (VO2max. Subjects provided 3 d food records on five protocol-specific occasions. Dietary calcium intake was averaged and categorized as low (1R A/C were analyzed with molecular methods. Genotypes were reduced from three to two: ACE II/ID and ACE DD; or AT1R AA and AT1R CC/AC. Repeated measure ANCOVA tested if BP differed among experiments, dietary calcium intake level and RAS polymorphisms. Results Systolic BP (SBP decreased 6 mm Hg after 40% and 60% VO2max compared to non-exercise control for 10 h with LowCa (p 2max versus non-exercise control for 10 h among ACE II/ID (6 mm Hg and AT1R AA (8 mm Hg; and by 8 mm Hg after 40% VO2max among ACE DD and AT1R CC/CA (p 2max compared to non-exercise control for 10 h (p 2max (p ≥ 0.05. Conclusion SBP decreased after exercise compared to non-exercise control among men with low but not high dietary calcium intake. Dietary calcium intake interacted with the ACE I/D and AT1R A/C polymorphisms to further modulate postexercise hypotension. Interactions among dietary calcium intake, exercise intensity and RAS polymorphisms account for some of the variability in the BP response to exercise.

    2016-04-01

    Previous studies have shown beneficial effects of individual dietary approaches for blood pressure (BP) control, but their relative effectiveness is not well established. We performed a systematic review of published dietary pattern interventions and estimated the aggregate BP effects through meta-analysis. PubMed, EMBASE, and Web of Science databases were searched to identify studies published between January 1, 1990 and March 1, 2015. Studies meeting specific inclusion and exclusion criteria were selected. Data were pooled using random effects meta-analysis models. Twenty-four trials with 23 858 total participants were included. The overall pooled net effect of dietary intervention on systolic BP and diastolic BP was -3.07 mm Hg (95% confidence interval, -3.85 to -2.30) and -1.81 mm Hg (95% confidence interval, -2.24 to -1.38), respectively. The Dietary Approaches to Stop Hypertension diet had the largest net effect (systolic BP, -7.62 mm Hg [95% confidence interval, -9.95 to -5.29] and diastolic BP, -4.22 mm Hg [95% confidence interval, -5.87 to -2.57]). Low-sodium; low-sodium, high-potassium; low-sodium, low-calorie; and low-calorie diets also led to significant systolic and diastolic BP reductions, whereas Mediterranean diet participants experienced a significant incremental reduction in diastolic but not systolic BP. Subgroup analysis also showed important variations in effectiveness based on duration, size, and participant demographics. In conclusion, dietary modifications are associated with clinically meaningful, though variable, reductions in BP. Some diets are more effective than others and under different circumstances, which has important implications from both clinical and public health perspectives. PMID:26902492

    Full Text Available Abstract Background Milk derived peptides have been identified as potential antihypertensive agents. The primary objective was to investigate the effectiveness of IPP-rich milk protein hydrolysates (MPH on reducing blood pressure (BP as well as to investigate safety parameters and tolerability. The secondary objective was to confirm or falsify ACE inhibition as the mechanism underlying BP reductions by measuring plasma renin activity and angiotensin I and II. Methods We conducted a randomized, placebo-controlled, double blind, crossover study including 70 Caucasian subjects with prehypertension or stage 1 hypertension. Study treatments consisted of daily consumption of two capsules MPH1 (each containing 7.5 mg Isoleucine-Proline-Proline; IPP, MPH2 (each containing 6.6 mg Methionine-Alanine-Proline, 2.3 mg Leucine-Proline-Proline, 1.8 mg IPP, or placebo (containing cellulose for 4 weeks. Results In subjects with stage 1 hypertension, MPH1 lowered systolic BP by 3.8 mm Hg (P = 0.0080 and diastolic BP by 2.3 mm Hg (P = 0.0065 compared with placebo. In prehypertensive subjects, the differences in BP between MPH1 and placebo were not significant. MPH2 did not change BP significantly compared with placebo in stage I hypertensive or prehypertensive subjects. Intake of MPHs was well tolerated and safe. No treatment differences in hematology, clinical laboratory parameters or adverse effects were observed. No significant differences between MPHs and placebo were found in plasma renin activity, or angiotensin I and II. Conclusions MPH1, containing IPP and no minerals, exerts clinically relevant BP lowering effects in subjects with stage 1 hypertension. It may be included in lifestyle changes aiming to prevent or reduce high BP. Trial registration ClinicalTrials.gov NCT00471263

    Background Mobile health, or mHealth, has increasingly been signaled as an effective means to expedite communication and improve medical regimen adherence, especially for patients with chronic health conditions such as stroke. However, there is a lack of data on attitudes of stroke patients toward mHealth. Such information will aid in identifying key indicators for feasibility and optimal implementation of mHealth to prevent and/or decrease rates of secondary stroke. Our objective was to ascertain stroke patients’ attitudes toward using mobile phone enabled blood pressure (BP) monitoring and medication adherence and identify factors that modulate these attitudes. Methods Sixty stroke patients received a brief demonstration of mHealth devices to assist with BP control and medication adherence and a survey to evaluate willingness to use this technology. Results The 60 participants had a mean age of 57 years, were 43.3% male, and 53.3% were White. With respect to telecommunication prevalence, 93.3% owned a cellular device and 25% owned a smartphone. About 70% owned a working computer. Regarding attitudes, 85% felt comfortable with a doctor or nurse using mHealth technologies to monitor personal health information, 78.3% believed mHealth would help remind them to follow doctor’s directions, and 83.3% were confident that technology could effectively be used to communicate with health care providers for medical needs. Conclusions Mobile device use is high in stroke patients and they are amenable to mHealth for communication and assistance in adhering to their medical regimens. More research is needed to explore usefulness of this technology in larger stroke populations.

    Blood pressure measurement is the cornerstone for the diagnosis, the treatment and the research on arterial hypertension, and all of the decisions about one of these single aspects may be dramatically influenced by the accuracy of the measurement. Over the past 20 years or so, the accuracy of the conventional Riva-Rocci/Korotkoff technique of blood pressure measurement has been questioned and efforts have been made to improve the technique with automated devices. In the same period, recognition of the phenomenon of white coat hypertension, whereby some individuals with an apparent increase in blood pressure have normal, or reduced, blood pressures when measurement is repeated away from the medical environment, has focused attention on methods of measurement that provide profiles of blood pressure behavior rather than relying on isolated measurements under circumstances that may in themselves influence the level of blood pressure recorded. These methodologies have included repeated measurements of blood pressure using the traditional technique, self-measurement of blood pressure in the home or work place, and ambulatory blood pressure measurement using innovative automated devices. The purpose of this review to serve as a source of practical information about the commonly used methods for blood pressure measurement: the traditional Riva-Rocci method and the automated methods.

    The present study investigated the effects of repeated administration of Korodin(®), a combination of camphor and crataegus berry extract, on blood pressure and attentional functioning. This study was conducted based on a randomized, placebo-controlled, double-blind design. 54 persons participated (33 female, 21 male) with a mean age of 24.3 years. Blood pressure and body mass index were in the normal range. Participants received 20 drops of either Korodin(®) or a placebo for four times with interjacent time intervals of about 10 min. Blood pressure was measured sphygmomanometrically before and after each administration. Attentional performance was quantified by using two paper-and-pencil tests, the d2 Test of Attention and Digit Symbol Test. Greater increases in blood pressure occurred after the four Korodin(®) administrations in comparison to the four placebo administrations. The performance in two parameters of d2 Test of Attention was consistently superior after the intake of Korodin(®). The excellent tolerability and safety of Korodin(®), even after a total consumption of 80 drops, was confirmed. PMID:25172798

    Traditional Thai massage (TTM) has been applied widely to promote relaxation. However, there is little evidence to support its efficacy on academic stress. A randomised controlled trial was performed to examine the acute effects of TTM on cortisol level, blood pressure, heart rate and stress perception in academic stress. This prospective trial included 36 physiotherapy students with a self perceived stress score of between 3 and 5. They were randomly allocated into the TTM (18 people) group or the control group (18 people). Saliva cortisol level, blood pressure, heart rate and stress perception rating were measured before and after the intervention. Both groups showed a significant reduction in cortisol level and heart rate when compared with baseline (p < 0.001). There were no significant differences in cortisol level between the two groups. The results suggest the need for further study into other possible physiological effects on stress of TTM. PMID:27210845

    Many of the flavonoids found in grapes and grape products such as juice or wine have been known to exert antioxidant, anti-inflammatory, platelet inhibitory and arterial relaxing effects either in vitro, in animal studies and in human trials. This study was designed to test the effect of Concord grape juice consumption on altering blood pressure in hypertensive patients. Forty subjects were given 5.5 ml/kg body weight/day of either Concord grape juice (CGJ) or a calorie-matched placebo drink every day for 8 weeks. Blood pressure (BP) was measured on weeks 0, 4 and 8. Compared to baseline, in the CGJ group systolic BP was reduced on average by 7.2 mm Hg (p = 0.005) and diastolic BP was reduced on average by 6.2 mm Hg (p = 0.001) at the end of 8 weeks. Comparable changes in the group getting the placebo product were -3.5 mm Hg (NS) and -3.2 mm Hg (p = 0.05) Consuming Concord grape juice, which is high in polyphenolic compounds, may favorably affect BP in hypertensive individuals.

The nighttime blood pressures...... were almost similar in the two groups (108 vs. 110; 65 vs. 67; 78 vs. 82 mm Hg, NS). Conversely, HR was significantly higher in the patients both in the daytime (86 vs. 72/min, P < .0001) and at night (80 vs. 64/min, P < .0001). Consequently, the reduction in blood pressure and HR from daytime to...

    Indirect arterial blood pressure measurement has not changed substantially since its introduction by Riva-Rocci in 1986, Korotkoff in 1905 and Recklinghausen in 1906. Random measurements in the clinic or practice reflect only incompletely the dynamic nature of the blood pressure. Blood pressure recordings by patients themselves have provided more information through better temporal resolution, however, exact characterization of the pressure response throughout the entire day and, in particular, during physical exertion are not enabled; the latter are especially important with regard to diagnosis and treatment of hypertension. In 1966, therefore, radiotelemetric transmission of direct, continuously-measured arterial blood pressure was developed which enabled beat-to-beat registration of blood pressure, outside the laboratory, during normal daily life and sport activities. The initial results showed a marked variability of the blood pressure during the course of the day (Figure 1). Excessive blood pressure increases were observed during exposure to cold, static and dynamic exercise and to a lesser degree during automobile driving and exposure to heat (Figure 3). Recording of the pressure curves via transmission by radiotelemetry shows a high degree of accuracy and temporal resolution, spatial and situational freedom but is invasive and costly in terms of personnel. The same holds true for direct continuous blood pressure registration and storage on a portable tape recorder. Portable, automatic blood pressure measuring units for ambulatory monitoring employ indirect auscultatory or oscillometric recording with a cuff. As compared with the radiotelemetric direct continuous blood pressure measuring method, the indirect method has subordinate temporal resolution, that is, the measurements are only intermittent.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2676813

Altered characteristics to the circadian rhythm of blood pressure, which may result in adverse health outcomes, have been observed in both prediabetes and diabetes. We have investigated the circadian variability of blood pressure in patients with type 1 and type 2 diabetes. Chronobiologically interpreted ambulator...

    AIMS: To assess the effects of weight gain on metabolic control, plasma lipids and blood pressure in patients with Type 1 diabetes. METHODS: Patients in the EURODIAB Prospective Complications Study (n = 3250) were examined at baseline and 1800 (55%) were re-examined a mean of 7.3 years later. Patients had Type 1 diabetes, defined as a diagnosis made before age 36 years and with a need for continuous insulin therapy within a year of diagnosis. Patients were aged 15-60 years at baseline and were stratified for age, sex and duration of diabetes. RESULTS: The change in HbA(1c) from baseline to follow-up examination was significantly more favourable in those who gained 5 kg or more during follow-up (\\'marked weight gain\\') than in patients who gained less or no weight or lost weight (\\'less or no weight gain\\'). In those with marked weight gain, there was a significantly greater rise in plasma triglycerides and total cholesterol and significantly less favourable changes in low-density lipoprotein and high-density lipoprotein cholesterol compared with those with less or no weight gain, with or without adjustment for HbA(1c). Systolic and diastolic blood pressure also rose significantly more in the group with marked weight gain. CONCLUSION: Weight gain in patients with Type 1 diabetes has adverse effects on plasma lipids and blood pressure, despite a small improvement in glycaemic control.

    Full Text Available As our understanding of the underlying aetiology of hypertension is far from adequate, over 90% of patients with hypertension receive a diagnosis of essential hypertension. This non-specific diagnosis leads to suboptimal therapeutics and a major problem with non-compliance. Understanding the normal control of blood pressure (BP is, hence, important for a better understanding of the disease.This review attempts to unravel the present understanding of BP control. The local mechanisms of BP control, the neural mechanisms, renal-endocrine mechanisms, and a variety of other hormones that have a bearing in normal BP control are discussed and the possible role in the pathophysiology is alluded to.

    We have previously shown that hyperhomocysteinaemia is common in elderly heart failure patients, and is associated with endothelial dysfunction, impaired vasodilatory capacity and a low-grade inflammation. In the present study we examined if supplementation with B6, B12 and folate could normalize the hyperhomocysteinaemia and if so, in turn, would improve the associated parameters. This was an open study without placebo control on heart failure patients with plasma homocysteine > 15 microM. Measurements of cutaneous vascular reactivity, blood pressure, inflammatory activity and endothelial function were performed before and after intervention with intra-individual comparisons. The treatment reduced homocysteine to near normal values and enhanced the hyperaemic response to acetylcholine related to the response to heat. The mean arterial blood pressure and pulse rate was reduced. There was no effect on inflammatory activity, plasma levels of von Willebrand factor, subjective health quality or the hyperaemic responses to sodium nitroprusside or local warming. Hyperhomocysteinaemia in heart failure patients is multifactorial in origin. Folate deficiency, inflammatory activity and reduced renal function could be contributing. It is suggested that supplementation with B-vitamins can improve the vasodilatory capacity and reduce the blood pressure but additional studies are required to confirm this. PMID:16236143

Despite compelling evidence supporting the beneficial effects of therapeutic lifestyle changes (TLC for blood pressure (BP reduction, the effectiveness of these approaches in primary care practices remains untested, especially among African Americans, who share a disproportionately greater burden of HTN-related outcomes. Methods/Design This randomized controlled trial tests the effectiveness of a practice-based comprehensive therapeutic lifestyle intervention, delivered through group-based counseling and motivational interviewing (MINT-TLC versus Usual Care (UC in 200 low-income, African Americans with uncontrolled hypertension. MINT-TLC is designed to help patients make appropriate lifestyle changes and develop skills to maintain these changes long-term. Patients in the MINT-TLC group attend 10 weekly group classes focused on healthy lifestyle changes (intensive phase; followed by 3 monthly individual motivational interviewing (MINT sessions (maintenance phase. The intervention is delivered by trained research personnel with appropriate treatment fidelity procedures. Patients in the UC condition receive a single individual counseling session on healthy lifestyle changes and print versions of the intervention materials. The primary outcome is within-patient change in both systolic and diastolic BP from baseline to 6 months. In addition to BP control at 6 months, other secondary outcomes include changes in the following lifestyle behaviors from baseline to 6 months: a physical activity, b weight loss, c number of daily servings of fruits and vegetables and d 24-hour urinary sodium excretion.

    Full Text Available Better understanding is needed for antihypertensive medication initiation and lifestyle modification among younger populations with elevated blood pressure. This study aimed to assess health behavior change after receiving a report of elevated blood pressure among African Americans and Caucasians younger than 50 years old. We used the Coronary Artery Risk Development in Young Adults (CARDIA repository dataset. By examination year twenty, 424 out of 2,478 Caucasian and 2,637 African American participants had received feedback from the CARDIA study due to elevated blood pressure readings. Blood pressure was measured by trained CARDIA researchers at the participant's home and was repeatedly recorded at seven examinations over twenty years. A feedback/referral letter was sent to participants with an elevated blood pressure reading. On average, participants first had an elevated blood pressure reading at the age of 34. After receiving the feedback letter, 44% of the previously undiagnosed participants received a formal diagnosis. In addition, 23% initiated the use of antihypertensive medication if they had not received medication treatment before. Among the participants with at-risk lifestyle behaviors, 40% reduced alcohol consumption, 14% increased exercise level, 11% stopped smoking, and 8% reached normal weight. While none of the studied patient factors were associated with lifestyle modification, age had a positive impact on antihypertensive medication initiation (p<0.05.

    2013-12-01

    Blood pressure measurement in the diagnosis and management of hypertension, including the technique required for ambulatory blood pressure monitoring and home blood pressure monitoring, will be reviewed in this article. Home and ambulatory measurements are widely used, both to confirm the diagnosis and to improve adherence to therapy. The major advantage of out-of-office blood pressure monitoring is that it provides a large number of blood pressure measurements away from the medical environment, which represents a more reliable assessment of actual blood pressure than office blood pressure. The advantage of ambulatory blood pressure monitoring is its unique ability to measure nocturnal blood pressure. Although not fully validated in large-scale clinical trials, ambulatory blood pressure monitoring appears to correlate best with prognosis. Ambulatory blood pressure monitoring and home blood pressure monitoring provide somewhat different information on the subject's blood pressure status, and the two methods should thus be regarded as complementary, rather than competitive or alternative.

  4. What Blood Pressure Goal in Type-2 Diabetes?

    Directory of Open Access Journals (Sweden)

    Nilsson PM

    2011-01-01

    Full Text Available Hypertension in diabetes is a wellknown risk factor for cardiovascular diseases that should be taken seriously. Observational studies have shown a more or less linear relationship between systolic blood pressure levels and risk, but this does not correspond with the outcome results of intervention trials to lower blood pressure. In fact, tight blood pressure control has only been shown to be of general benefit in the range of 130–135 mmHg systolic blood pressure, but not below except for stroke prevention. On the other hand, there might even exist an increased risk for coronary heart disease events and cardiovascular mortality at lower ranges based on data from observational studies. This fact, in combination with the increased costs and risk of serious adverse events, cautions clinicians not to lower systolic blood pressure too much in susceptible patients with longer diabetes duration, more comorbidities, and in older age groups. However, we should not lose sight of the challenge that still around half of all patients with type-2 diabetes are not even below the desired minimum goal of 140 mmHg systolic blood pressure. This calls for improved actions to control blood pressure as part of a general strategy to counteract all cardiovascular risk factors in patients with type-2 diabetes. The higher the risk, the more ambitious should be the approach to screen, detect, treat, and monitor these risk factors.

If the pressure in the cuff is relieved, blood starts coming through the compressed arterial segment during systole and causes auscultatory sound and, the first sound, which, in Korotkoff’s opinion, is a measurement of systolic blood pressure. In the same BP measurement, when normal blood flow is fully restored, the auscultatory sounds disappear and, the last sound, which, in Korotkoff's opinion is a measurement of diastolic blood pressure. Listening to Korotkoff sounds (K-sounds to determine systolic and diastolic blood pressure (BP has been the standard for noninvasive BP measurement in medical practices for nearly 100 years and it is the essential tool used for evaluation and assessment of patients with hypertension and risks of cardiovascular diseases (CVD by physicians and nurses despite limited understanding of the nature of K-sounds. This article focuses particularly on the cardiovascular biomechanics of the first and last auscultatory sound and suggests two new terminologies; Highest systolic blood pressure and Baseline systolic blood pressure to represent the systolic pressure and diastolic pressure, respectively. Experimenting blood pressures on the basis of these two new suggested terminologies may reveal various additional undiscovered aspects of normal BP and abnormal BP.

    2016-06-01

    In orthognathic surgery, maxillary (CNV2) and mandibular (CNV3) divisions of the trigeminal nerve can be blocked successfully prior to surgery. In this study, it was hypothesized that regional blocks (nerve block over a particular region: bilateral CNV2 and CNV3 divisions of the trigeminal nerve) would decrease the total requirement for intraoperative anaesthetic agents and facilitate the process of hypotensive anaesthesia. Local anaesthesia containing 1/100,000 epinephrine and 10ml 0.5% levobupivacaine was injected into the planned incisions in 50 patients. Twenty-five patients (group A) underwent orthognathic surgery without regional blocks and another 25 patients (group B) underwent surgery with regional blocks. The anaesthetic protocol was the same in both groups and administered by a single anaesthesiologist. The mean arterial pressure was recorded at several points throughout the operation, as well as all the medications used. The blood loss and the amounts of medications administered were lower in group B than in group A. In patients receiving regional blocks, the amounts of fentanyl and nicardipine required were significantly lower. The use of pre-emptive anaesthesia in orthognathic surgery may reduce the overall amounts of medications required for hypotensive anaesthesia, facilitate the intraoperative control of blood pressure, and decrease intraoperative blood loss.

    To examine the effect of genetic variance on blood pressure, sodium homeostasis, and its regulatory determinants, we studied 37 pairs of monozygotic twins and 18 pairs of dizygotic twins under conditions of volume expansion and contraction. We found that, in addition to blood pressure and body size, sodium excretion in response to provocative maneuvers, glomerular filtration rate, the renin-angiotensin system, and the sympathetic nervous system are influenced by genetic variance. To elucidate the interaction of genetic factors and an environmental influence, namely, salt intake, we restricted dietary sodium in 44 families of twin children. In addition to a modest decrease in blood pressure, we found heterogeneous responses in blood pressure indicative of sodium sensitivity and resistance which were normally distributed. Strong parent-offspring resemblances were found in baseline blood pressures which persisted when adjustments were made for age and weight. Further, mother-offspring resemblances were observed in the change in blood pressure with sodium restriction. We conclude that the control of sodium homeostasis is heritable and that the change in blood pressure with sodium restriction is familial as well. These data speak to the interaction between the genetic susceptibility to hypertension and environmental influences which may result in its expression. PMID:3553721

    Fifty-nine healthy omnivores volunteered for a randomized crossover trial with a lacto-ovo-vegetarian (L-O-V) diet. Twenty-one 1-day diet records were kept throughout the project as a means of assessing food and nutrient intakes, and samples of serum and urine were assayed to evaluate change in prostanoid metabolism. While on the L-O-V diet subjects ate more vegetable protein, wholegrain cereals, polyunsaturated oils, fruits and vegetables, and avoided eating meat, fish or poultry. The L-O-V diet contained significantly more polyunsaturated fatty acids, fibre, vitamin C, vitamin E, magnesium, calcium and potassium, and less total protein, saturated fat, monounsaturated fat and vitamin B12 than the control omnivore diet. Changes in nutrient intakes were subjected to principal components analysis to identify dimensions of change in nutrient intakes. Three Factors accounted for 83% of the total variation in dietary intake. Blood pressure changes were significantly and negatively (F = 17.4, P less than 0.001 for systolic; F = 6.09, P = 0.02 for diastolic pressure) related to individual scores for only one Factor--that representing an increase in intake of polyunsaturated fat, fibre, vitamin C, vitamin E, calcium and magnesium, and a fall in intake of protein and vitamin B12. Blood pressure changes were unrelated to change in body weight or sodium intake. Serum and urinary prostanoids were not affected by eating the L-O-V diet. PMID:3011891

    Objectives The aim of this study was to investigate the effects of aroma foot massage on blood pressure, anxiety, and health-related quality of life (QOL) in Japanese community-dwelling men and women using a crossover randomized controlled trial. Methods Fifty-seven eligible participants (5 men and 52 women) aged 27 to 72 were randomly divided into 2 intervention groups (group A: n = 29; group B: n = 28) to participate in aroma foot massages 12 times during the 4-week intervention period. Systolic and diastolic blood pressure (SBP and DBP, respectively), heart rate, state anxiety, and health-related QOL were measured at the baseline, 4-week follow-up, and 8-week follow-up. The effects of the aroma foot massage intervention on these factors and the proportion of participants with anxiety were analyzed using a linear mixed-effect model for a crossover design adjusted for participant and period effects. Furthermore, the relationship between the changes in SBP and state anxiety among participants with relieved anxiety was assessed using a linear regression model. Results Aroma foot massage significantly decreased the mean SBP (p = 0.02), DBP (p = 0.006), and state anxiety (p = 0.003) as well as the proportion of participants with anxiety (p = 0.003). Although it was not statistically significant (p = 0.088), aroma foot massage also increased the score of mental health-related QOL. The change in SBP had a significant and positive correlation with the change in state anxiety (p = 0.01) among participants with relieved anxiety. Conclusion The self-administered aroma foot massage intervention significantly decreased the mean SBP and DBP as well as the state anxiety score, and tended to increase the mental health-related QOL scores. The results suggest that aroma foot massage may be an easy and effective way to improve mental health and blood pressure.

    This device provides non-invasive beat-to-beat blood pressure measurements and can be worn over the upper arm for prolonged durations. Phase and waveform analyses are performed on filtered proximal and distal photoplethysmographic (PPG) waveforms obtained from the brachial artery. The phase analysis is used primarily for the computation of the mean arterial pressure, while the waveform analysis is used primarily to obtain the pulse pressure. Real-time compliance estimate is used to refine both the mean arterial and pulse pressures to provide the beat-to-beat blood pressure measurement. This wearable physiological monitor can be used to continuously observe the beat-to-beat blood pressure (B3P). It can be used to monitor the effect of prolonged exposures to reduced gravitational environments and the effectiveness of various countermeasures. A number of researchers have used pulse wave velocity (PWV) of blood in the arteries to infer the beat-to-beat blood pressure. There has been documentation of relative success, but a device that is able to provide the required accuracy and repeatability has not yet been developed. It has been demonstrated that an accurate and repeatable blood pressure measurement can be obtained by measuring the phase change (e.g., phase velocity), amplitude change, and distortion of the PPG waveforms along the brachial artery. The approach is based on comparing the full PPG waveform between two points along the artery rather than measuring the time-of-flight. Minimizing the measurement separation and confining the measurement area to a single, well-defined artery allows the waveform to retain the general shape between the two measurement points. This allows signal processing of waveforms to determine the phase and amplitude changes.

    Recently, the adverse effects of long working hours on the cardiovascular systems of workers in Japan, including "Karoshi" (death from overwork), have been the focus of social concern. However, conventional methods of health checkups are often unable to detect the early signs of such adverse effects. To evaluate the influence of overtime work on the cardiovascular system, we compared 24-hour blood pressure measurements among several groups of male white-collar workers. As a result, for those with normal blood pressure and those with mild hypertension, the 24-hour average blood pressure of the overtime groups was higher than that of the control groups; for those who periodically did overtime work, the 24-hour average blood pressure and heart rate during the busy period increased. These results indicate that the burden on the cardiovascular system of white-collar workers increases with overtime work. PMID:8899576

Diet is an important factor that can be modified to prevent hypertension. According to the US Department of Health and Human Services, dietary patterns are defined as the quantities, proportions, and variety or combinations of different foods and beverages in diets and the frequency with which they are habitually consumed. In this review, the vegetarian dietary pattern is introduced with a focus on the effect on blood pressure (BP. Although the available evidence is limited, according to a previous meta-analysis of controlled trials, vegetarian dietary patterns significantly reduced systolic and diastolic BPs. One of the common features of a vegetarian diet is weight loss, which might, at least partially, explain the effect on BP. Other possible factors such as sodium, potassium, protein, amino acids, vitamin B-12, antioxidants, fiber, and the microbiome are introduced as possible mechanisms. Further studies are needed with non-Western populations to determine the most effective vegetarian dietary pattern and to explore the exact mechanisms by which these dietary patterns affect BP.

  11. Noninvasive blood pressure measurement in large vessels

    International Nuclear Information System (INIS)

    Pulse pressure in the aorta was evaluated by the measurement of pulse wave velocity (PWV) and blood flow velocity (BFV). PWV reflects the elasticity of the vessel and was determined by a time-of-flight method. BFV was measured by analyzing the change of magnetization decay due to flow in multiecho experiments. If one neglects pulse wave reflections at vascular branch points and flow resistance due to blood viscosity, pulse pressure is proportional to PWV and BFV. Noninvasive MR imaging measurements were obtained in 12 patients, all of whom underwent correlative arterial catheterization. Values varied between 35 and 100 mm Hg. The results demonstrated a high correlation between the two methods

    Objective To determine the statistical characteristics of blood pressure (BP) readings from a large number of head‐injured patients. Methods The BrainIT group has collected high time‐resolution physiological and clinical data from head‐injured patients who require intracranial pressure (ICP) monitoring. The statistical features of this dataset of BP measurements with time resolution of 1 min from 200 patients is examined. The distributions of BP measurements and their relationship with simultaneous ICP measurements are described. Results The distributions of mean, systolic and diastolic readings are close to normal with modest skewing towards higher values. There is a trend towards an increase in blood pressure with advancing age, but this is not significant. Simultaneous blood pressure and ICP values suggest a triphasic relationship with a BP rising at 0.28 mm Hg/mm Hg of ICP, for ICP up to 32 mm Hg, and 0.9 mm Hg/mm Hg of ICP for ICP from 33 to 55 mm Hg, and falling sharply with rising ICP for ICP >55 mm Hg. Conclusions Patients with head injury appear to have a near normal distribution of blood pressure readings that are skewed towards higher values. The relationship between BP and ICP may be triphasic.

    The aim of this study was to investigate the short-term blood pressure (BP) variability (BPV) derived from ambulatory blood pressure monitoring (ABPM) in patients with primary aldosteronism (PA), either idiopathic hyperaldosteronism (IHA) or aldosterone-producing adenoma (APA), in comparison with patients with essential hypertension (EH) and normotensive (NT) controls. Thirty patients with PA (16 with IHA and 14 with APA), 30 patients with EH, and 30 NT controls, matched for sex, age, body mass index, and antihypertensive therapy, were studied. The standard deviation (SD) of 24-hour, daytime, and nighttime BP; 24-hour weighted SD of BP; and 24-hour BP average real variability were not different between patients with PA and those with EH (P=not significant). All BPV indices were higher in patients with PA, either IHA or APA subtypes, and patients with EH, compared with NT controls (P<.001 to P<.05). ABPM-derived short-term BPV is increased in patients with PA, and it may represent an additional cardiovascular risk factor in this disease. The role of aldosterone excess in BPV has to be clarified.

    1 We studied the effects of verapamil on sudden elevation in blood pressure, microcirculation and arterial baroreflex sensitivity (BRS). 2 Thirty experiments (10 controls and 20 with verapamil) were performed in rabbits sedated using pentobarbital infusion (5 mg kg(-1) h(-1)). 3 BRS, mean femoral artery blood pressure (MAP), heart rate (HR) and ear lobe skin microcirculatory blood flow, estimated using microphotoelectric plethysmography (MPPG), were simultaneously measured during 30 min of verapamil infusion (20 mug kg(-1) min(-1)). BRS was assessed from HR and MAP responses to intravenous phenylephrine (Ph) and by power spectral analysis using transfer function (TF) from MAP to the HR (BRS(Ph,TF)). 4 Verapamil significantly increased microcirculatory blood flow, and decreased BRS(Ph,TF) and phenylephrine-induced abrupt elevation in MAP (MAP(AE)). 5 A significant inverse correlation was found between verapamil-induced changes in MAP(AE), BRS and in microcirculatory blood flow, measured before phenylephrine blood pressure ramps (DeltaMAP(AE) with DeltaBRS(TF), r = -0.47, P < 0.036; DeltaMAP(AE) with DeltaMPPG, r = -0.49, P < 0.025). 6 These results suggest involvement of the arterial baroreflex and vascular blood pressure-buffering mechanisms, their enhancement by verapamil, and thus a potential benefit of verapamil in cardiovascular conditions where patients present with abrupt high elevations in blood pressure.

    Aim:To test the effects of atenolol and amlodipine,either alone or in combination,on blood pressure,blood pressure variability (BPV),baroreflex sensitivity (BRS),and the prevalence of stroke in stroke-prone spontaneously hypertensive rats (SHR-SP). Methods:In the first set of the study,24 8-month-old,female SHR-SP rats were randomly divided into 3 groups. Blood pressure,heart period,and BRS were determined before and after the intragastric administration of atenolol (10 mg/kg) and amlodipine (1.0 mg/kg),either alone or in combination. In the second set of the study,40 male and 40 female rats were randomly assigned to 1 of the and both (10 male and 10 female in each group). The stroke incident and survival time were recorded. Results:Atenolol and amlodipine,either alone or in combination,significantly decreased blood pressure,with the exception of the amlodipine-induced effect on diastolic blood pressure. Meanwhile,only the combination treatment significantly decreased the BPV levels for the same period.The q-values calculated by the probability sum analysis were 1.17 and 2.67 for systolic and diastolic blood pressure,respectively,and were 2.48 and 2.10 for systolic and diastolic BPV,respectively,following administration. Neither drug exhibited any significant effect on BRS. Atenolol and amlodipine,either alone or in combination,significantly increased the lifespan of SHR-SP,with the best effeet elicited by the combination therapy. Conclusion:A significant synergism exists between atenolol and amlodipine in lowering and stabilizing blood pressure in SHR-SP. Combination therapy may be an optimal strategy for the prevention of stroke in hypertension.

    Full Text Available Abstract Background Dark chocolate and flavanol-rich cocoa products have attracted interest as an alternative treatment option for hypertension, a known risk factor for cardiovascular disease. Previous meta-analyses concluded that cocoa-rich foods may reduce blood pressure. Recently, several additional trials have been conducted with conflicting results. Our study summarises current evidence on the effect of flavanol-rich cocoa products on blood pressure in hypertensive and normotensive individuals. Methods We searched Medline, Cochrane and international trial registries between 1955 and 2009 for randomised controlled trials investigating the effect of cocoa as food or drink compared with placebo on systolic and diastolic blood pressure (SBP/DBP for a minimum duration of 2 weeks. We conducted random effects meta-analysis of all studies fitting the inclusion criteria, as well as subgroup analysis by baseline blood pressure (hypertensive/normotensive. Meta-regression analysis explored the association between type of treatment, dosage, duration or baseline blood pressure and blood pressure outcome. Statistical significance was set at P Results Fifteen trial arms of 13 assessed studies met the inclusion criteria. Pooled meta-analysis of all trials revealed a significant blood pressure-reducing effect of cocoa-chocolate compared with control (mean BP change ± SE: SBP: -3.2 ± 1.9 mmHg, P = 0.001; DBP: -2.0 ± 1.3 mmHg, P = 0.003. However, subgroup meta-analysis was significant only for the hypertensive or prehypertensive subgroups (SBP: -5.0 ± 3.0 mmHg; P = 0.0009; DBP: -2.7 ± 2.2 mm Hg, P = 0.01, while BP was not significantly reduced in the normotensive subgroups (SBP: -1.6 ± 2.3 mmHg, P = 0.17; DBP: -1.3 ± 1.6 mmHg, P = 0.12. Nine trials used chocolate containing 50% to 70% cocoa compared with white chocolate or other cocoa-free controls, while six trials compared high- with low-flavanol cocoa products. Daily flavanol dosages ranged from 30

    Organ blood flow is determined by perfusion pressure and vasomotor tone in the resistance vessels of the organ. Local factors that regulate vasomotor tone include myogenic and metabolic autoregulation, flow-mediated and conducted responses, and vasoactive substances released from red blood cells. The relative importance of each of these factors…

    2010-07-01

    In this paper, the oscillometric waveform measured by automatic non-invasive blood pressure meters (NIBP) is analyzed by transforming the data from the time domain to the frequency domain. The signal's spectrum of the oscillometric waveform is in current literature badly understood or explored. The only known link between the oscillometric waveform and the blood pressure is the maximum of the oscillometry's envelope equalling the mean arterial pressure (MAP). This link is established under the assumption that the oscillometry is an AM-signal. Unfortunately, computing the MAP is difficult in practice due to the non-sinusoidal nature of the actual measured signals. In this paper, we construct the best AM-signal approximation of the oscillometry and explore its use to compute the MAP.

    The current definition of drug-resistant hypertension includes patients with uncontrolled (URH) (taking ≥3 antihypertensive medications) and controlled hypertension (CRH; blood pressure [BP] ≤140/90 mm Hg) (taking ≥4 medications). The authors hypothesized that all-cause mortality is reduced when URH is controlled. Qualified patients followed at the Washington DC VA Medical Center were included. BPs were averaged for each year of follow-up. In 2006, among 2906 patients who met the criteria for drug-resistant hypertension, 628 had URH. During follow-up, 234 patients were controlled (group 1) and 394 patients remained uncontrolled (group 2). The mortality rate among patients with URH was 28% (110 of 394) and among patients with CRH was 13% (30 of 234), a 54% reduction (P<.01). Multivariate analysis identified independent predictors of mortality as uncontrolled HTN (hazard ratio, 2.5; 95% confidence interval, 1.67-3.75; P<.01), age (hazard ratio, 1.03; 95% confidence interval, 1.01-1.04; P<.01), and diabetes (hazard ratio, 1.46; 95% confidence interval, 1.04-2.05; P<.027). The authors conclude that controlling drug-resistant hypertension markedly reduces all-cause mortality. PMID:26440866

  8. Blood pressure modifies retinal susceptibility to intraocular pressure elevation.

    Zheng He

    Full Text Available Primary open angle glaucoma affects more than 67 million people. Elevated intraocular pressure (IOP is a risk factor for glaucoma and may reduce nutrient availability by decreasing ocular perfusion pressure (OPP. An interaction between arterial blood pressure and IOP determines OPP; but the exact contribution that these factors have for retinal function is not fully understood. Here we sought to determine how acute modifications of arterial pressure will affect the susceptibility of neuronal function and blood flow to IOP challenge. Anaesthetized (ketamine:xylazine Long-Evan rats with low (∼60 mmHg, sodium nitroprusside infusion, moderate (∼100 mmHg, saline, or high levels (∼160 mmHg, angiotensin II of mean arterial pressure (MAP, n = 5-10 per group were subjected to IOP challenge (10-120 mmHg, 5 mmHg steps every 3 minutes. Electroretinograms were measured at each IOP step to assess bipolar cell (b-wave and inner retinal function (scotopic threshold response or STR. Ocular blood flow was measured using laser-Doppler flowmetry in groups with similar MAP level and the same IOP challenge protocol. Both b-wave and STR amplitudes decreased with IOP elevation. Retinal function was less susceptible to IOP challenge when MAP was high, whereas the converse was true for low MAP. Consistent with the effects on retinal function, higher IOP was needed to attenuated ocular blood flow in animals with higher MAP. The susceptibility of retinal function to IOP challenge can be ameliorated by acute high BP, and exacerbated by low BP. This is partially mediated by modifications in ocular blood flow.

  9. Blood-Pressure Measuring System Gives Accurate Graphic Output

    Science.gov (United States)

    1965-01-01

    The problem: To develop an instrument that will provide an external (indirect) measurement of arterial blood pressure in the form of an easily interpreted graphic trace that can be correlated with standard clinical blood-pressure measurements. From sphygmograms produced by conventional sphygmographs, it is very difficult to differentiate the systolic and diastolic blood-pressure pulses and to correlate these indices with the standard clinical values. It is nearly impossible to determine these indices when the subject is under physical or emotional stress. The solution: An electronic blood-pressure system, basically similar to conventional ausculatory sphygmomanometers, employing a standard occluding cuff, a gas-pressure source, and a gas-pressure regulator and valve. An electrical output transducer senses cuff pressure, and a microphone positioned on the brachial artery under the occluding cuff monitors the Korotkoff sounds from this artery. The output signals present the conventional systolic and diastolic indices in a clear, graphical display. The complete system also includes an electronic timer and cycle-control circuit.

    Full Text Available Diabetes mellitus (DM is now considered as the major cause of end-stage kidney failure, and hypertension (HTN is one of the main determinants of progression of renal disease. The aim of this study was to assess the role of blood pressure (BP by ambulatory blood pressure monitoring (ABPM in children and adolescents with type-1 DM and its correlation with micro-albuminuria (MA and diabetic control. Eighty-one patients with type-1 DM (mean age 13 ± 4 years, whose duration of DM was at least two years, were enrolled in this study. The prevalence of HTN based on ABPM was 28.4%, while by casual method it was 32.1%. The pattern of HTN was as follows: mean systolic HTN 27.2%, mean diastolic HTN 11.2%, daytime systolic HTN 17.3%, daytime diastolic HTN 6.2%, night systolic HTN 30.9%, and night diastolic HTN 29.7%. The systolic and diastolic BP loads were 33.4 and 27.2%, respectively. About 70.4% of the patients were non-dippers, 12.4% had masked HTN, and 3.7% had white coat HTN. The pre-valence of MA was 34.6% and that of abnormal HbA 1 c was 82.7%. There was no correlation bet-ween HTN and both MA and HbA 1 c; also, no correlation was found between the duration of dia-betes and HbA 1 c. Moreover, no significant correlation was found between the duration of diabetes and MA (P = 0.080. Despite the high prevalence of abnormal BP profile among diabetic children, prospective longitudinal studies considering the other major risk factors, particularly genetic factors, which have an impact on the progression to diabetic nephropathy, are recommended.

    Full Text Available Background: As the case detection rates of hypertension increase in adult Nigerians, achieving target blood pressure (BP control has become an important management challenge.Objectives: To describe medication adherence and BP control amongst adult Nigerians with primary hypertension attending a primary care clinic of a tertiary hospital in a resource-poor environment in Eastern Nigeria.Methods: A cross-sectional study was carried out in 140 adult patients with primary hypertension who have been on treatment for at least 6 months at the primary care clinic of Federal Medical Centre, Umuahia. A patient was said to have achieved goal BP control if the BP was < 140 per 90 mmHg. Adherence was assessed in the previous 30 days using a pretested researcher-administered questionnaire on 30 days of self-reported therapy. Adherence was graded using an ordinal scoring system of 0–4; an adherent patient was one who scored 4 points in the previous 30 days. Reasons for non-adherence were documented.Results: Adherence to medication and BP control rates were 42.9% and 35.0% respectively. BP control was significantly associated with medication adherence (p = 0.03, antihypertensive medication duration ≥3 years (p = 0.042, and taking ≥ one form of antihypertensive medication (p = 0.04. BP at the recruitment visit was significantly higher than at the end of the study (p = 0.036. The most common reason for non-adherence was forgetfulness (p = 0.046. Conclusion: The rate of BP control amongst the study population was low, which may be connected with low medication adherence. This study urges consideration of factors relating to adherence alongside other factors driving goal BP control.

  13. Relationship between blood manganese and blood pressure in the Korean general population according to KNHANES 2008

    International Nuclear Information System (INIS)

    Introduction: We present data on the association of manganese (Mn) level with hypertension in a representative sample of the adult Korean population who participated in the Korean National Health and Nutrition Examination Survey (KNHANES) 2008. Methods: This study was based on the data obtained by KNHANES 2008, which was conducted for three years (2007-2009) using a rolling sampling design involving a complex, stratified, multistage, probability-cluster survey of a representative sample of the noninstitutionalized civilian population of South Korea. Results: Multiple regression analysis after controlling for covariates, including gender, age, regional area, education level, smoking, drinking status, hemoglobin, and serum creatinine, showed that the beta coefficients of log blood Mn were 3.514, 1.878, and 2.517 for diastolic blood pressure, and 3.593, 2.449, and 2.440 for systolic blood pressure in female, male, and all participants, respectively. Multiple regression analysis including three other blood metals, lead, mercury, and cadmium, revealed no significant effects of the three metals on blood pressure and showed no effect on the association between blood Mn and blood pressure. In addition, doubling the blood Mn increased the risk of hypertension 1.828, 1.573, and 1.567 fold in women, men, and all participants, respectively, after adjustment for covariates. The addition of blood lead, mercury, and cadmium as covariates did not affect the association between blood Mn and the prevalence of hypertension. Conclusion: Blood Mn level was associated with an increased risk of hypertension in a representative sample of the Korean adult population. - Highlights: → We showed the association of manganese with hypertension in Korean population. → This study was based on the data obtained by KNHANES 2008. → Blood manganese level was associated with an increased risk of hypertension.

    This article looks at the association of maternal blood pressure with the blood pressure of the offspring from birth to childhood. The Barker hypothesis states that maternal and "in utero" attributes during pregnancy affect a child's cardiovascular health throughout life. We present an analysis of a unique dataset that consists of three distinct developmental processes: maternal cardiovascular health during pregnancy; fetal development; and child's cardiovascular health from birth to 14 years. This study explored whether a mother's blood pressure reading in pregnancy predicts fetal development and determines if this in turn is related to the future cardiovascular health of the child. This article uses data that have been collected prospectively from a Jamaican cohort which involves the following three developmental processes: (1) maternal cardiovascular health during pregnancy which is the blood pressure and anthropometric measurements at seven time-points on the mother during pregnancy; (2) fetal development which consists of ultrasound measurements of the fetus taken at six time-points during pregnancy; and (3) child's cardiovascular health which consists of the child's blood pressure measurements at 24 time-points from birth to 14 years. The inter-relationship of these three processes was examined using linear mixed effects models. Our analyses indicated that attributes later in childhood development, such as child's weight, child's baseline systolic blood pressure (SBP), age and sex, predict the future cardiovascular health of children. The results also indicated that maternal attributes in pregnancy, such as mother's baseline SBP and SBP change, predicted significantly child's SBP over time. PMID:25178900

    In this paper, a simulation model based on the partially pressurized collapsible tube model for reproducing noninvasive blood pressure measurement is presented. The model consists of a collapsible tube, which models the pressurized part of the artery, rigid pipes connected to the collapsible tube, which model proximal and distal region far from the pressurized part, and the Windkessel model, which represents the capacitance and the resistance of the distal part of the circulation. The blood flow is simplified to a one-dimensional system. Collapse and expansion of the tube is represented by the change in the cross-sectional area of the tube considering the force balance acting on the tube membrane in the direction normal to the tube axis. They are solved using the Runge-Kutta method. This simple model can easily reproduce the oscillation of inner fluid and corresponding tube collapse typical for the Korotkoff sounds generated by the cuff pressure. The numerical result is compared with the experiment and shows good agreement. PMID:16995754

    A fall in systolic blood pressure without other symptoms of anaphylactic shock has been described following the administration of drugs containing dipyrone. This adverse reaction was first observed in 4 patients by the same team in 1972-1973. Ten further cases with a fall in systolic blood pressure by at least 20 mm Hg occurring within minutes to 6 hours after intravenous administration of dipyrone are presented in this paper. In each of them this adverse reaction was considered to be probable or even definite. During the years 1976-1981 drug exposure was registered for all 15 678 patients of the two medical divisions of Comprehensive Hospital Drug Monitoring Berne. This adverse reaction was found in 7, representing 0.34% of the 2053 patients who received intravenous treatment with a dipyrone preparation. PMID:6658424

    Background Active engagement in the management of hypertension is important in improving self-management behaviors and clinical outcomes. Mobile phone technology using wireless monitoring tools are now widely available to help individuals monitor their blood pressure, but little is known about the conditions under which such technology can effect positive behavior changes or clinical outcomes. Objective To study the influence of wireless self-monitoring program and patient activation measures on health behaviors, medication adherence, and blood pressure levels as well as control of blood pressure in hypertensive patients. Methods We examined a subset of 95 hypertensive participants from a 6-month randomized controlled trial designed to determine the utility of a wireless self-monitoring program (n=52 monitoring program, n=43 control), which consisted of a blood pressure monitoring device connected with a mobile phone, reminders for self-monitoring, a Web-based disease management program, and a mobile app for monitoring and education, compared with the control group receiving a standard disease management program. Study participants provided measures of patient activation, health behaviors including smoking, drinking, and exercise, medication adherence, and blood pressure levels. We assessed the influence of wireless self-monitoring as a moderator of the relationship between patient activation and health behaviors, medication adherence, and control of blood pressure. Results Improvements in patient activation were associated with improvements in cigarette smoking (beta=−0.46, Pimprove their health management with an added benefit above and beyond that of motivation alone.

  8. The effect of ventricular assist devices on cerebral blood flow and blood pressure fractality

    International Nuclear Information System (INIS)

    Biological signals often exhibit self-similar or fractal scaling characteristics which may reflect intrinsic adaptability to their underlying physiological system. This study analysed fractal dynamics of cerebral blood flow in patients supported with ventricular assist devices (VAD) to ascertain if sustained modifications of blood pressure waveform affect cerebral blood flow fractality. Simultaneous recordings of arterial blood pressure and cerebral blood flow velocity using transcranial Doppler were obtained from five cardiogenic shock patients supported by VAD, five matched control patients and five healthy subjects. Computation of a fractal scaling exponent (α) at the low-frequency time scale by detrended fluctuation analysis showed that cerebral blood flow velocity exhibited 1/f fractal scaling in both patient groups (α = 0.95 ± 0.09 and 0.97 ± 0.12, respectively) as well as in the healthy subjects (α = 0.86 ± 0.07). In contrast, fluctuation in blood pressure was similar to non-fractal white noise in both patient groups (α = 0.53 ± 0.11 and 0.52 ± 0.09, respectively) but exhibited 1/f scaling in the healthy subjects (α = 0.87 ± 0.04, P < 0.05 compared with the patient groups). The preservation of fractality in cerebral blood flow of VAD patients suggests that normal cardiac pulsation and central perfusion pressure changes are not the integral sources of cerebral blood flow fractality and that intrinsic vascular properties such as cerebral autoregulation may be involved. However, there is a clear difference in the fractal scaling properties of arterial blood pressure between the cardiogenic shock patients and the healthy subjects

    Although the vascular volume response of hypertensive men during exercise has been rather well characterized, the effect of resting heat exposure in this patient population has not been examined. This was done in the present report in seven men with high blood pressure (BP) (i.e., diastolic pressure greater than 12 kPa (90 mmHg) upon initial interview) and 5 normotensive control subjects. 50 min after each subject had consumed an amount of water equal to 1% of his body weight, he reclined on a cot. 10 min later the subject was carried into an environmental chamber equilibrated at Tdb = 45 degrees C, Twb = 28 degrees C. Free-flowing venous blood samples were obtained from a cubital vein, and BP and heart rate were measured, before the heat exposure and at 15 min intervals during the experiment. Within 30 min systolic, diastolic and mean BP of the high BP subjects had decreased to normal levels; no BP changes were detected in normotensive subjects. Accompanying this depressor response was an exaggerated elevation in plasma glucose concentration. No alterations were found with haematocrit, plasma osmolality or electrolytes, or total protein and albumin. The data suggest that heat exposure may have been more stressful for the subjects with high BP than for their controls. This finding implies that phasic depressor responses may be as important as phasic pressor episodes in the aetiology of established essential hypertension.

    2010-08-21

    The incidence and severity of hypertension are affected by nutritional status and intake of many nutrients. Excessive energy intake and obesity are major causes of hypertension. Obesity is associated with increased activity of the renin-angiotensin-aldosterone and sympathetic nervous systems, possibly other mineralcorticoid activity, insulin resistance, salt-sensitive hypertension and excess salt intake, and reduced kidney function. High sodium chloride intake strongly predisposes to hypertension. Increased alcohol consumption may acutely elevate blood pressure. High intakes of potassium, polyunsaturated fatty acids, and protein, along with exercise and possibly vitamin D, may reduce blood pressure. Less-conclusive studies suggest that amino acids, tea, green coffee bean extract, dark chocolate, and foods high in nitrates may reduce blood pressure. Short-term studies indicate that specialized diets may prevent or ameliorate mild hypertension; most notable are the Dietary Approaches to Stop Hypertension (DASH) diet, which is high in fruits, vegetables, and low-fat dairy products, and the DASH low-sodium diet. Long-term compliance to these diets remains a major concern. PMID:20645853

    Full Text Available Abstract Background Despite the impact of hypertension and widely accepted target values for blood pressure (BP, interventions to improve BP control have had limited success. Objectives We describe the design of a 'translational' study that examines the implementation, impact, sustainability, and cost of an evidence-based nurse-delivered tailored behavioral self-management intervention to improve BP control as it moves from a research context to healthcare delivery. The study addresses four specific aims: assess the implementation of an evidence-based behavioral self-management intervention to improve BP levels; evaluate the clinical impact of the intervention as it is implemented; assess organizational factors associated with the sustainability of the intervention; and assess the cost of implementing and sustaining the intervention. Methods The project involves three geographically diverse VA intervention facilities and nine control sites. We first conduct an evaluation of barriers and facilitators for implementing the intervention at intervention sites. We examine the impact of the intervention by comparing 12-month pre/post changes in BP control between patients in intervention sites versus patients in the matched control sites. Next, we examine the sustainability of the intervention and organizational factors facilitating or hindering the sustained implementation. Finally, we examine the costs of intervention implementation. Key outcomes are acceptability and costs of the program, as well as changes in BP. Outcomes will be assessed using mixed methods (e.g., qualitative analyses--pattern matching; quantitative methods--linear mixed models. Discussion The study results will provide information about the challenges and costs to implement and sustain the intervention, and what clinical impact can be expected.

    2013-11-01

    Full Text Available The human voice is remarkable, complex and delicate. All parts of the body play some role in voice production and may be responsible for voice dysfunction. The larynx contains muscles that are surrounded by blood vessels connected to circulatory system. The pressure of blood in these vessels should be related with dynamic variation of vocal cord parameters. These parameters are directly related with acoustic properties of speech. Acoustic voice analysis can be used to characterize the pathological voices. This paper presents the classification of high blood pressure and normal with the aid of voice signal recorded from the patients. Various features have been extracted from the voice signal of healthy persons and persons suffering from high blood pressure. Simulation results show differences in the parameter values of healthy and pathological persons. Then an optimum feature vector is prepared and kmean classification algorithm was implemented for data classification. The 79% classification efficiency was obtained.

  20. Ambulatory Blood Pressure Monitoring in Clinical Practice: A Review

    Science.gov (United States)

    Viera, Anthony J.; Shimbo, Daichi

    2016-01-01

    Ambulatory blood pressure monitoring offers the ability to collect blood pressure readings several times an hour across a 24-hour period. Ambulatory blood pressure monitoring facilitates the identification of white-coat hypertension, the phenomenon whereby certain individuals who are not on antihypertensive medication show elevated blood pressure in a clinical setting but show non-elevated blood pressure averages when assessed by ambulatory blood pressure monitoring. Additionally, readings can be segmented into time windows of particular interest, e.g., mean daytime and nighttime values. During sleep, blood pressure typically decreases, or dips, such that mean sleep blood pressure is lower than mean awake blood pressure. A non-dipping pattern and nocturnal hypertension are strongly associated with increased cardiovascular morbidity and mortality. Approximately 70% of individuals dip ≥10% at night, while 30% have non-dipping patterns, when blood pressure remains similar to daytime average, or occasionally rises above daytime average. The various blood pressure categorizations afforded by ambulatory blood pressure monitoring are valuable for clinical management of high blood pressure since they increase accuracy for diagnosis and the prediction of cardiovascular risk.

    2007-10-01

    Full Text Available Many hypertensive patients affected by endogenous Cushing's syndrome (CS persist with high blood pressure (HBP despite good control of cortisol excess. We assessed the effect of preoperative ketoconazole administration and of definitive treatment of CS on arterial hypertension and analysed the factors involved in the persistence of hypertension. We assessed retrospectively 71 patients with CS and HBP (60 women, 11 men; 50 pituitary, 21 adrenal successfully treated by surgery and/or radiotherapy; 19 of them received ketoconazole (KNZ before surgery. After treatment, patients were divided into those with persistent high blood pressure (PHBP and those with normal blood pressure (NBP. As possible predictive factors for PHBP we analysed age, duration and family history of HBP, pre-treatment 24 hour urinary free cortisol (24h-UFC and body mass index (BMI. HBP normalized in 53 out of 71 patients (74.6%, regardless of the origin of Cushing's syndrome. PHBP patients were older (p=0.003, had longer duration (p=0.007 and higher systolic blood pressure before treatment (p=0.046 than NBP patients. Thirteen out of 19 patients (68.4% treated with ketoconazole, normalized their hypertension and remained normotensive after successful surgery. Five patients became normotensive only after surgery. In conclusion: a blood pressure levels normalized in most patients after remission of CS; b ketoconazole was effective for the control of HBP, and seems to be a good indicator of post-surgical outcome, and c higher age at presentation, longer duration of hypertension and higher systolic blood pressure figures before treatment negatively influence normalization of blood pressure after resolution of Cushing's syndrome.Muchos pacientes con síndrome de Cushing (SC permanecen hipertensos a pesar del control del exceso glucocorticoideo.

    Full Text Available A Alex Ilechie, Sandra TettehDepartment of Optometry, University of Cape Coast, GhanaBackground: Energy drinks contain a wide variety of ingredients including caffeine, for which there have been conflicting reports regarding its effects on intraocular pressure (IOP and blood pressure. The aim of this study was to investigate the acute effects of an energy drink (Red Bull® on the IOP and blood pressure of healthy young adults.Methods: Thirty healthy university students of either gender, aged 18–30 (mean 23.20 ± 2.81 years were randomly selected to participate in this study. The subjects were randomly divided into two groups (experimental and control and were asked to abstain from caffeine for 48 hours prior to and during the study. Baseline IOP and blood pressure were measured. The experimental group (n = 15 consumed one can of the energy drink (containing 85 mg of caffeine in 250 mL and measurements were repeated at 30, 60, and 90 minutes, while the control group drank 250 mL of water and were tested over the same time period.Results: When compared with baseline, a significant decrease (P < 0.05 in mean IOP at 60 and 90 minutes was observed in the experimental group. There was no corresponding change in systolic or diastolic blood pressure.Conclusion: Our results suggest that energy drinks (ie, Red Bull produce a significant reduction in IOP but have no effect on blood pressure. These findings may be interpreted as reflecting the effect of the combination of caffeine and taurine in the Red Bull energy drink. This effect may result from the known hypotensive effect of taurine, and warrants further study.Keywords: acute effect, intraocular pressure, blood pressure, glaucoma, caffeine, taurine

  9. Microcirculation impairment and blood pressure in sepsis

    Full Text Available Blood pressure is crucial for the tissue perfusion, oxygenation andelimination of metabolites in normal tissue. In septic patients itmay be altered by several mechanisms. Endothelial lesions andimpaired vasoregulation resulting from bacteriemia may producevasodilatation, hypotension, tissue hypoxia and decrease in theblood velocity. These events may favour disseminated intravascularcoagulation in septic patients, and thus pronounce perfusionmisdistribution. Since hypotension is commonly treated byvasoactive drugs to increase vascular tone toward normal values,more pronounced peripheral tissue ischemia may result. Duringthe process of blood pressure regulation in septic patients a diversityof physiological parameters should be encountered, i.e. age,body weight, core temperature, overall patients’ cardiovascularperformance, anemia, and protein status. In a healthy, adult person,in the absence of other causes of hypotension systolic bloodpressure of > 90 mmHg or mean arterial pressure ≥ 70 mmHgshould maintain adequate tissue perfusion. Together with specificantibiotics, therapeutic procedures like haemodilution, use of vasoconstrictors,vasopressin and its analogue terlipressin, corticosteroidsare currently used to improve outcome of hypotensive septicpatients. Numerous studies were undertaken to point the valuesof the biochemical tests suggesting a need for prompt intervention.The arterial lactate, cortisol response, TNF, interleukin (IL6, IL-12p70 and IL-12p40 production, together with submucosal(gastric intramucosal or sublingual CO2 values were proven as indicative.These may suggest whether microcirculatory impairmentis reversible or not, and which therapeutic maneuver should beappropriate.

    Full Text Available Abstract The development of non-pharmacological approaches to hypertension (HA is critical for both prevention and treatment. This study examined the hemodynamic and biochemical responses of medicated hypertensive women to resistance exercise with blood flow restriction (vascular occlusion. Twenty-three women were randomly assigned to one of three groups: High intensity strength training (n = 8; low-intensity resistance exercise with occlusion (n = 8; and control (n = 7. The first two groups underwent eight weeks of training performed twice a week, including three series of wrist flexion exercises with or without vascular occlusion. The exercised with occlusion group showed pre- to post-test reduction in systolic and diastolic blood pressure, mean arterial pressure, and double product, whereas the other groups showed no significant hemodynamic changes. In conclusion, resistance exercise during 8 weeks was effective in lowering blood pressure in medicated hypertensive subjects.

    Yaling Zhao

    Full Text Available OBJECTIVES: To assess trends in average blood pressure levels and prevalence, awareness, treatment, and control of hypertension among adults in a rural area of Northwest China, and to determine associated risk factors. METHODS: Four cross-sectional population-based surveys were conducted between 1982 and 2010 among randomly selected adults in rural areas of Hanzhong, in Northwest China. Data on blood pressure, body mass index, family history of hypertension, and socio-demographic and lifestyle characteristics were collected in similar way by trained investigators in four surveys. Data of 8575 participants aged 35-64 years was analyzed. Averages and proportions were adjusted for age and sex. RESULTS: Average blood pressure in the population has increased since 1982 from 76.9 mm Hg to 79.6 mm Hg in 2010 (diastolic and from 120.9 to 129.7 mm Hg (systolic. Prevalence of hypertension increased from 18.4% in 1982 to 30.5% in 2010, and awareness of hypertension increased from 16.8% to 38.4% in 2010. Treatment of hypertension increased from 1.0% in 1982 to 17.4% in 2010, and control of hypertension increased from 0.1% in 1982 to 3.5% in 2010. All these gradients were statistically significant (P<0.01 for trend. Population blood pressure and prevalence, awareness and treatment of hypertension were positively associated with increasing age, body mass index and having family history of hypertension. CONCLUSIONS: Average blood pressure levels and the prevalence, awareness, treatment and control of hypertension among adults in rural areas of Hanzhong have increased since 1982. However, awareness, treatment and control rates remain low. Public health programs and practical strategies are required to improve prevention and control of hypertension in rural Northwest China. In particular, attention should be given to the elderly and obese, and to those with a family history of hypertension, while raising awareness and treatment among younger adults.

    Objective: As glucagon-like peptide-1 receptor agonists lower blood pressure (BP) in type 2 diabetes mellitus (T2DM), we examined BP control in relation to targets set by international bodies prior to randomization in the Liraglutide Effect and Action in Diabetes: Evaluation of cardiovascular outcome Results (LEADER) trial. Methods: We analyzed baseline data from LEADER (NCT01179048), an ongoing phase 3B, randomized, double-blind, placebo-controlled cardiovascular outcomes trial examining the cardiovascular safety of the glucagon-like peptide-1 receptor agonist liraglutide in 9340 people with T2DM from 32 countries [age (all mean ± SD) 64 ± 7.2 years, BMI 32.5 ± 6.3 kg/m2, duration of diabetes 12.7 ± 8.0 years], all of whom were at high risk for cardiovascular disease (CVD). Results: A total of 81% (n = 7592) of participants had prior CVD and 90% (n = 8408) had a prior history of hypertension. Despite prescription of multiple antihypertensive agents at baseline, only 51% were treated to a target BP of less than 140/85 mmHg and only 26% to the recommended baseline BP target of less than 130/80 mmHg. In univariate analyses, those with prior CVD were prescribed more agents (P < 0.001) and had lower BP than those without (137 ± 18.8/78 ± 10.6 mmHg versus 140 ± 17.7/80 ± 9.9 mmHg; P < 0.001). In logistic regression analyses, residency in North America (64% treated to <140/85 mmHg; 38% treated to <130/80 mmHg) was the strongest predictor of BP control. Conclusion: These contemporary data confirm that BP remains insufficiently controlled in a large proportion of individuals with T2DM at high cardiovascular risk, particularly outside North America. Longitudinal data from the LEADER trial may provide further insights into BP control in relation to cardiovascular outcomes in this condition. PMID:26855018

    Full Text Available Previous studies showed that soy bean has the potential to improve many aspects of diabetes state and provide metabolic benefits that aid in weight management. We aimed to determine the effects of soy bean flour enriched bread on anthropometric indices and blood pressure among type 2 diabetic patients. This randomized, crossover, clinical trial was performed in 30 type 2 diabetic women. There were two trial periods for 6 weeks and a wash-out period for 4 weeks. In the soy bread diet period, 120 g of soy bean flour enriched bread was consumed each day instead of the same amount of their usual bread or other cereal products. After a 4-week wash-out period, participants were crossed over for another 6 weeks. Mean (±SD age of study participants was 45.7 ± 3.8 years. The results of our study showed no significant effects of soy bean flour enriched bread on anthropometric indices and blood pressure among diabetic patients. Despite the slight reduction in BMI, waist circumference, and percent of body fat, there were no significant differences in changes of these values between two groups. No significant changes in waist to hip ratio and blood pressure were seen.

    Summary Objectives To assess whether the effects of community-based educational interventions to improve blood pressure, weight and health behaviours benefit participants with lower educational levels more than those with higher educational levels. Design Secondary data analysis. Setting Two 12-month community-based educational interventions, one led by trained peers and one delivered by health professionals. Participants A total of 403 hypertensive individuals, grouped by education (high school or less; 1–3 years college; 4 + years college). Main outcome measures Blood pressure, weight, physical activity and fruit and vegetable intake. Results We found that changes in blood pressure, weight and physical activity were similar across education levels; college graduates consumed more daily servings of fruits and vegetables at baseline (3.7 versus 3.6 for those with 12–15 years and 3.1 for those with < 12 years, p = 0.0112), and increased intake more after the intervention (+0.4 versus −0.1 and −0.1, p = 0.0142). The two methods of delivery – peer-led versus professional – had similar effects on all measures. Conclusions We conclude that educational interventions, whether delivered by peers or professionals, may improve chronic disease self-management among participants but do not confer greater benefits on participants with lower educational levels.

    We examined the hypothesis that lowered cognitive performance plays a role in the relation between elevated blood pressure and physical disability in performing basic physical tasks. A community-based sample (N=1025) free from stroke and dementia (mean age: 61.1 years; SD: 13.0 years; 59.8% women) was used. Using path analysis, systolic and diastolic blood pressures (predictor variable) measured over multiple longitudinal examinations were averaged and related to multiple measures of cognition (intermediate variable) and physical ability (PA; outcome variable) measured at wave 6 of the Maine-Syracuse Study. PA was indexed by time required to execute standing, walking, and turning tests. A best-fit path model including blood pressure and multiple demographic and cardiovascular disease covariates was used. Paths from systolic blood pressure to global performance, verbal memory, and abstract reasoning (Similarities test) were significant (Pspatial organization/memory, verbal memory, working memory, and abstract reasoning. Regardless of the blood pressure predictor, lower cognitive performance (intermediate variable) was related to lower PA (outcome) in the path from blood pressure to PA. The direct path from blood pressure to PA was significant only for systolic blood pressure. Cognitive performance mediates between blood pressure and PA. As compared with systolic blood pressure, more domains of cognitive functioning intervene between diastolic blood pressure and PA. PMID:20404216

    Full Text Available Background: Blood pressure varies between populations due to ethnic and environmental factors. Therefore, normal blood pressure values should be determined for different populations. Aims: The aim of this survey was to produce blood pressure nomograms for Lebanese children in order to establish distribution curves of blood pressure by age and sex. Subjects and Methods: We conducted a survey of blood pressure in 5710 Lebanese schoolchildren aged 5 to 15 years (2918 boys and 2792 girls, and studied the distribution of systolic and diastolic blood pressure in these children and adolescents. Blood pressure was measured with a mercury sphygmomanometer using a standardized technique. Results: Both systolic and diastolic blood pressure had a positive correlation with weight, height, age, and body mass index (r= 0.648, 0.643, 0.582, and 0.44, respectively (P < .001. There was no significant difference in the systolic and diastolic blood pressure in boys compared to girls of corresponding ages. However, the average annual increase in systolic blood pressure was 2.86 mm Hg in boys and 2.63 mm Hg in girls, whereas the annual increase in diastolic blood pressure was 1.72 mm Hg in boys and 1.48 mm Hg in girls. The prevalence of high and high-normal blood pressure at the upper limit of normal (between the 90th and 95th percentile, at risk of future hypertension if not managed adequately, was 10.5% in boys and 6.9% in girls, with similar distributions among the two sexes. Conclusions: We present the first age-specific reference values for blood pressure of Lebanese children aged 5 to 15 years based on a good representative sample. The use of these reference values should help pediatricians identify children with normal, high-normal and high blood pressure.

    Aim: To investigate the possible synergism of hydrochlorothiazide and nitrendipine on reducing both blood pressure (BP) and blood pressure variability (BPV) in spontaneously hypertensive rats (SHR). Methods: Seventy animals were randomly divided into seven groups. The doses were 5 and 10 nig/kg for nitrendipine, 10 and 20 mg/kg for hydrochlorothiazide and 10+5, 20+10 mg/kg, respectively, for the combination of these two drugs and 0.8% carboxym-ethylcellulose as control. The drugs were given via a catheter of gastric fistula. BP was then continuously recorded for 5 h from 1 h before drug administration to the end of 4th hour after drug administration, in conscious and freely moving rats. Results: The effects on both BP and BPV reduction of the combination of hydrochlorothiazide and nitrendipine were greater than the single drug in SHR. The two drugs possessed an obvious synergism on both systolic blood pressure (q=1.79 with small dose and q=1.23 with large dose) and systolic blood pressure variability reduction (q=1.79 with small dose and q=1.39 with large dose) in SHR.Conclusion: The present work clearly demonstrated that there was a synergistic effect between hydrochlorothiazide and nitrendipine in lowering and stabilizing BP in SHR.

    The mechanisms by which heat stress impairs the control of blood pressure leading to compromised orthostatic tolerance are not thoroughly understood. A possible mechanism may be an attenuated blood pressure response to a given increase in sympathetic activity. This study tested the hypothesis that whole body heating attenuates the blood pressure response to a non-baroreflex-mediated sympathoexcitatory stimulus.

  12. Neuroendocrine humoral and vascular components in the pressor pathway for brain angiotensin II: a new axis in long term blood pressure control.

    Directory of Open Access Journals (Sweden)

    John M Hamlyn

    Full Text Available Central nervous system (CNS administration of angiotensin II (Ang II raises blood pressure (BP. The rise in BP reflects increased sympathetic outflow and a slower neuromodulatory pressor mechanism mediated by CNS mineralocorticoid receptors (MR. We investigated the hypothesis that the sustained phase of hypertension is associated also with elevated circulating levels of endogenous ouabain (EO, and chronic stimulation of arterial calcium transport proteins including the sodium-calcium exchanger (NCX1, the type 6 canonical transient receptor potential protein (TRPC6, and the sarcoplasmic reticulum calcium ATPase (SERCA2. Wistar rats received a chronic intra-cerebroventricular infusion of vehicle (C or Ang II (A, 2.5 ng/min, for 14 days alone or combined with the MR blocker, eplerenone (A+E, 5 µg/day, or the aldosterone synthase inhibitor, FAD286 (A+F, 25 µg/day. Conscious mean BP increased (P50-fold in the A+F group. Central Ang II increased arterial expression of NCX1, TRPC6 and SERCA2 (2.6, 1.75 and 3.7-fold, respectively; P<0.01 but not when co-infused with E or F. Adrenal and pituitary EO were unchanged. We conclude that brain Ang II activates a CNS-humoral axis involving plasma EO. The elevated EO reprograms peripheral ion transport pathways known to control arterial Na(+ and Ca(2+ homeostasis; this increases contractility and augments sympathetic effects. The new axis likely contributes to the chronic pressor effect of brain Ang II.

    Full Text Available Background Informatics tools may help support hypertension management.Objective To design, implement and evaluate a web-based system for patient anti-hypertensive medication self-titration.Methods Study stages included: six focus groups (50 patients to identify barriers/facilitators to patient medication self-titration, software design informed by qualitative analysis of focus group responses and a six-month single-arm pilot study (20 patients to assess implementation feasibility.Results Focus groups emphasised patient need to feel confident that their own primary care providers were directly involved and approved of the titration protocol. Physicians required 3.3 ± 2.8 minutes/patient to create individualised six-step medication pathways for once-monthly blood pressure evaluations. Pilot participants (mean age of 51.5 ± 11 years, 45% women, mean baseline blood pressure 139/84 ± 12.2/7.5 mmHg had five medication increases, two non-adherence self-reports, 52months not requiring medication changes, 24 skipped months and 17 months with no evaluations due to technical issues. Four pilot patients dropped out before study completion. From baseline to study completion, blood pressure decreased among the 16 patients remaining in the study (8.0/4.7 mmHg, p = 0.03 for both systolic and diastolic pressures.Conclusions Lessons learned included the benefit of qualitative patient analysis prior to system development and the feasibility of physicians designing individual treatment pathways. Any potential clinical benefits were offset by technical problems, the tendency for patients to skip their monthly self-evaluations and drop outs. To be more widely adopted such systems must effectively generalise to a wider range of patients and be integrated into clinical workflow.

  14. Longitudinal analysis of arterial blood pressure and heart rate response to acute behavioral stress in rats with type 1 diabetes mellitus and in age-matched controls

    2011-08-01

    Full Text Available We recorded via telemetry the arterial blood pressure (BP and heart rate (HR response to classical conditioning following the spontaneous onset of autoimmune diabetes in BBDP/Wor rats versus age-matched, diabetes resistant control (BBDR/Wor rats. Our purpose was to evaluate the autonomic regulatory responses to an acute stress in a diabetic state of up to 12 months duration. The stress was a 15 sec. pulsed tone (CS+ followed by a 0.5 sec. tail shock. The initial, transient increase in BP (i.e., the ‘first component’, or C1, known to be derived from an orienting response and produced by a sympathetic increase in peripheral resistance, was similar in diabetic and control rats through ~9 months of diabetes; it was smaller in diabetic rats 10 months after diabetes onset. Weakening of the C1 BP increase in rats that were diabetic for > 10 months is consistent with the effects of sympathetic neuropathy. A longer-latency, smaller, but sustained ‘second component’ (C2 conditional increase in BP, that is acquired as a rat learns the association between CS+ and the shock, and which results from an increase in cardiac output, was smaller in the diabetic vs. control rats starting from the first month of diabetes. A concomitant HR slowing was also smaller in diabetic rats. The difference in the C2 BP increase, as observed already during the first month of diabetes, is probably secondary to the effects of hyperglycemia upon myocardial metabolism and contractile function, but it may also result from effects on cognition. The small HR slowing concomitant with the C2 pressor event is probably secondary to differences in baroreflex activation or function, though parasympathetic dysfunction may contribute later in the duration of diabetes. The nearly immediate deficit after disease onset in the C2 response indicates that diabetes alters BP and HR responses to external challenges prior to the development of structural changes in the vasculature or autonomic

    We evaluated the performance of continuous non-invasive finger arterial pressure measurement using the volume-clamp technique (Finapres). This study was designed to compare finger arterial pressure with brachial blood pressure estimated by the auscultatory method in 217 children (90 boys and 127 girls) aged 4-16 years and in 38 adults (aged 18-45 years). Finger and brachial artery pressure readings were obtained consecutively from the ipsilateral side in the supine position. Finger arterial pressure waveforms were recorded in all children except 4 with small and thin fingers. There was good agreement for systolic pressure with only a slight underestimation of 1.9 mmHg and 5.1 mmHg lower for diastolic pressure. This difference most probably reflects inaccuracy of the auscultatory cuff method rather than an error in the Finapres. There was large inter-individual variability in Finapres recordings which might be due to differences in vasomotor tone, as demonstrated by systolic amplification in 5 patients with anorexia. However, Finapres showed a small within-subject variability (3.8 mmHg for systolic and 4.1 mmHg for diastolic pressure) determined in 5 patients during phenylephrine infusion, and as good reproducibility as the auscultatory method. These results suggest that finger arterial pressure measurement in children older than 6 years of age has similar accuracy as that in adults, and that this method is useful for clinical applications in children, especially for the non-invasive evaluation of autonomic control and cardiovascular reflexes involving transient and rapid blood pressure changes.

    There is growing concern about elevated blood pressure (BP) in children. The evidence for familial aggregation of childhood BP is substantial. Twin studies have shown that a large part of the familial aggregation of childhood BP is due to genes. The first part of this review provides the latest progress in gene finding for childhood BP, focusing on the combined effects of multiple loci identified from the genome-wide association studies on adult BP. We further review the evidence on the contribution of the genetic components of other family risk factors to the familial aggregation of childhood BP including obesity, birth weight, sleep quality, sodium intake, parental smoking, and socioeconomic status. At the end, we emphasize the promise of using genomic-relatedness-matrix restricted maximum likelihood (GREML) analysis, a method that uses genome-wide data from unrelated individuals, in answering a number of unsolved questions in the familial aggregation of childhood BP.

    @@ Over the past few years, the research team of Professor Ding-feng SU has reported an impressive quantity of experimental data about the relationships between blood pressure variability (BPV) and end-organ damage, a topic of obvious clinical interest. This research work has been summarized in a paper that appeared in the August issue of the renowned journal Trends in Pharmacological Sciences[1]. The studies by Su et al provide convincing evidence that BPV is an independent cardiovascular risk factor that should be considered as such and, therefore, might become an important target for therapeutic interventions. Besides these exciting perspectives in the prevention and treatment of cardiovasculardiseases, the work by Su et al raises a series of physiological questions.

    Full Text Available The aim of this study is to evaluate the efficacy of a Unani formulation in hypertension. A total of 90 patients with total cholesterol level of more than 220 mg/dl with associated conditions were included in this study. A total of 30 patients having a mean systolic blood pressure (BP of 133.86 mmHg comprising Group A received Unani formulation Safoof-e-Muhazzil (SM in its classical powder form in the dose of 5 g twice a day orally. Group B comprising of 30 patients with a mean systolic BP of 133.13 mmHg received same drug, but in compressed tablet form in the same dosage, whereas, 30 patients comprising Group C with a mean systolic BP of 129.45 mmHg, received Atorvastatin 10 mg as a standard control. Patients were evaluated on each follow-up at 2 nd , 4 th and 6 th week. The mean systolic BP in Group A and B before treatment was 133.86 ± 3.028 mmHg and 133.13 ± 2.852 mmHg, which significantly decreased to 119.33 ± 1.922 mmHg (P < 0.001 and 119 ± 1.760 mmHg (P < 0.001 respectively. In the control Group C before treatment BP was 129.45 ± 2.499 mmHg and after treatment it significantly decreased to 124.34 ± 1.794 mmHg (P < 0.01. The percentage change after treatment was 10.85%, 10.61% and 3.94% respectively in each group. Mean diastolic BP in Group A and B before treatment was 85.06 ± 2.11 mmHg and 84.56 ± 1.5 mmHg, which significantly decreased to 79.06 ± 1.56 mmHg (P < 0.001 and 79.96 ± 1.15 mmHg (P < 0.001 respectively, BP before treatment in Group C was 83.23 ± 1.588 mmHg, which was decreased to 124.34 ± 1.794 mmHg (P < 0.01. The study results indicate that the test drug was quite effective in reducing both systolic as well as diastolic BP.

    Full Text Available BACKGROUND: Blood pressure (BP measurement is a routine procedure but errors are frequently committed during BP recording. AIMS AND SETTINGS: The aim of the study was to look at the prevalent practices in the institute regarding BP recording. The study was conducted in the Medicine Department at Government Medical College, Chandigarh, a teaching institute for MBBS students. METHODS: A prospective, observational study was performed amongst the 80 doctors in a tertiary care hospital. All of them were observed by a single observer during the act of BP recording. The observer was well versed with the guidelines issued by British Hypertension Society (BHS and the deviations from the standard set of guidelines issued by BHS were noted. The errors were defined as deviations from these guidelines. STATISTICAL METHODS: The results were recorded as percentage of doctors committing these errors. RESULTS: In our study, 90% used mercury type sphygmomanometer. Zero error of the apparatus, hand dominance was not noted by any one. Every one used the standard BP cuff for recording BP. 70% of them did not let the patient rest before recording BP. 80% did not remove the clothing from the arm. None of them recorded BP in both arms. In out patient setting, 80% recorded blood pressure in sitting position and 14% in supine position. In all the patients where BP was recorded in sitting position BP apparatus was below the level of heart and 20% did not have their arm supported. 60% did not use palpatory method for noticing systolic BP and 70% did not raise pressure 30-40 mm Hg above the systolic level before checking the BP by auscultation. 80% lowered the BP at a rate of more than 2 mm/s and 60% rounded off the BP to nearest 5-10 mm Hg. 70% recorded BP only once and 90% of the rest re inflated the cuff without completely deflating and allowing rest before a second reading was obtained. CONCLUSION: The practice of recording BP in our hospital varies from the standard

    AIM: To investigate the effect of low central venous pressure (LCVP) on blood loss during hepatectomy for hepatocellular carcinoma (HCC).METHODS: By the method of sealed envelope,50 HCC patients were randomized into LCVP group (n = 25) and control group (n = 25). In LCVP group,CVP was maintained at 2-4 mmHg and systolic blood pressure (SBP) above 90 mmHg by manipulation of the patient's posture and administration of drugs during hepatectomy, while in control group hepatectomy was performed routinely without lowering CVP. The patients'preoperative conditions, volume of blood loss during hepatectomy, volume of blood transfusion, length of hospital stay, changes in hepatic and renal functions were compared between the two groups.RESULTS: There were no significant differences in patients' preoperative conditions, maximal tumor dimension, pattern of hepatectomy, duration of vascular occlusion, operationtime, weight of resected liver tissues, incidence of post-operative complications, hepatic and renal functions between the two groups. LCVP group had a markedly lower volume of total intraoperative blood loss and blood loss during hepatectomy than the control group, being 903.9±180.8 mL vs 2 329.4±2 538.4(W=495.5, P<0.01) and 672.4±429.9 mL vs1 662.6± 1932.1 (W=543.5, P<0.01). There were no remarkable differences in the pre-resection and post-resection blood losses between the two groups. The length of hospital stay was significantly shortened in LCVP group as compared with the control group, being 16.3±6.8 d vs21.5 ± 8.6 d (W= 532.5, P<0.05).CONCLUSION: LCVP is easily achievable in technique.Maintenance of CVP≤4 mmHg can help reduce blood loss during hepatectomy, shorten the length of hospital stay, and has no detrimental effects on hepatic or renal function.

    Blood pressure reflects a person's health.It is proposed here that the method of detecting blood pressure may be the key to improving the precision of blood pressure measurements. The oscillometric blood pressure measurement technique is widely used in automatic blood pressure measurement instruments correctly. A method of blood pressure measurement by oscillometric method is first presented. In the oscillometric method, the basic principle of the "feature point" method and the "amplitude characteristic ratios" method is also explained and discussed here. A new method of blood pressure measurement, namely the coefficient difference comparative method, is proposed here,which is based on the feature point method and amplitude characteristic ratios method. The method is proved both effective and reliable through the analysis of many cases and clinical tests. Utilizing Visual C++, software for this new and novel method was developed and passed criterion simulation apparatus test. When applied in hospital situation, its error was +/-5%. It is concluded that the oscillometric blood pressure measurement method can provide better means of blood pressure measurements reference for doctors.

    This study was designed to evaluate whether primary care physicians in Spain accurately diagnose the metabolic syndrome in hypertensive patients, to define the profile and management of these patients in clinical practice, and to ascertain the level of blood pressure and low-density lipoprotein cholesterol control. Data were analyzed from a cross-sectional survey involving 12,954 patients with hypertension (Prevención Cardiovascular en España en Atención Primaria: Intervención Sobre el Colesterol en Hipertensión [PRESCOT] study), wherein 52% of the cohort fulfilled the National Cholesterol Education Program-Adult Treatment Panel criteria for the metabolic syndrome. The majority of patients (54.6%) had 3 risk factors, 32.4% had 4, and 13% had 5 risk factors. Physician diagnosis of the metabolic syndrome was poor, with 43.7% of physicians missing the diagnosis and 12.9% wrongly diagnosing the metabolic syndrome. Blood pressure and low-density lipoprotein cholesterol control rates were very low, with only 4.7% of metabolic syndrome patients achieving control for both blood pressure and low-density lipoprotein cholesterol vs 13.5% for non-metabolic syndrome patients (P<.0001). These findings demonstrate that the metabolic syndrome is common in patients with hypertension and that it is generally poorly diagnosed and treated by primary care physicians. PMID:17684454

    Aim: To investigate the ouabain's effects on cardiac remodeling in rats. Methods:Male Sprague-Dawley rats were treated with ouabain. Systolic blood pressure(SBP) was recorded weekly. After 4 and 6 weeks, echocardiography were performed,hemodynamic parameters were measured by invasive cardiac catheterization,changes in cardiac ultrastructure were analyzed using transmission electron microscopy, the collagen fraction of the left ventricle was assessed with Picrosirius red stain, and RT-PCR was applied to evaluate the mRNA level of myosin heavy chain-α and-β in the left ventricle. Results: Having been treated with ouabain for 4 weeks, there was no significant difference in the mean SBP of the two groups.However, left ventricular hypertrophy, myocardial ultrastructure deterioration,and extracellular matrix remodeling were induced by ouabain treatment; meanwhile,cardiac systolic and diastolic performance were both worsened. Moreover, the cardiac MHC-β mRNA was upregulated by ouabain treatment, whereas MHC-αmRNA was downregulated. After 4 weeks, the mean SBP in the ouabain group began to increase and was significantly higher than that in control group after 6 weeks (P<0.01); the rats' cardiac structure and function were worsened.Conclusion: These results suggested that ouabain induces alterations in cardiac structure and function, and the effects happened before the increase of blood pressure. The results indicated that ouabain induced cardiac remodeling in rats independent of blood pressure.

    Objectives To observe the characteristic of ambulatory blood pressure monitoring in normotensive diabetic subjects with normoalbuminuria or microalbuminuria. Methods Fifty-two normotensive patients with type 2 diabetes received ambulatory blood pressure monitoring were divided into normoalbuminuric and microalbuminuric groups according to their albumin excretion rate, the other 28 normotensive subjects without diabetes were contributed as control group. Ambulatory blood pressure monitoring was performed on a working day and measurement of blood pressure circadian rhythm was analyzed. Results Normotensive microalbuminuric diabetic patients had higher night-time systolic blood pressure and more blood pressure burden than normotensive normoalbuminuric diabetic patients. Additionally, the microalbuminuric patients had a higher frequency of non-dippers than normoalbuminuric ones, although they were all normotensive. Compared to the normotensive non-diabetic control subjects, the nighttime systolic blood pressure and frequency of nondippers of the normoalbuminuric diabetic patients were significantly higher. Conclusions Intensive attention should be paid in control of blood pressure in diabetic patients to prevent and limit damage of target organ including kidney, even in those normotensive subjects.

    Full Text Available Abstract Background In an elderly, community based population we aimed at investigating antihypertensive and lipid lowering medication use in relation to own and familiar cardiovascular morbidity and diabetes mellitus, as well as to lifestyle factors and general health. We also examined levels of blood pressure in untreated and treated residents, to investigate factors correlating with blood pressure control. Methods A health survey carried out in 1997-9 in the county of Hordaland, Norway included a self-administered questionnaire mailed to 4 338 persons born in 1925-7. Drug use the day prior to filling in the questionnaire was reported. A health check-up was carried out, where their systolic and diastolic blood pressure (SBP and DBP, body mass index (BMI, and serum-cholesterol level were recorded. Results One third of respondents used one or more antihypertensive drugs, while 13% of men and women were treated with a statin. Diabetes mellitus, own or relatives'cardiovascular disease, having quit smoking, physical inactivity, and overweight correlated with antihypertensive treatment. Mean blood pressure was lower in respondents not on treatment. Among those on treatment, 38% of men and 29% of women had reached a target BP-level of lower than 140/90 mm Hg. Own cardiovascular disease and a low BMI correlated with good BP-control. Conclusion One third of 70–74 year old individuals living in the community used one or more antihypertensive drugs. Only around one third of those treated had reached a target BP-level of less than 140/90 mm Hg. Own cardiovascular disease and a low BMI correlated with good BP-control.

Data were collected from 400 college students (56.3% women from 16 to 63 years old. Fifteen trees were calculated in the training group for each sex, using different numbers and combinations of predictors. The result shows that for women BMI, WC, and WHR are the combination that produces the best prediction, since it has the lowest deviance (87.42, misclassification (.19, and the higher pseudo R2 (.43. This model presented a sensitivity of 80.86% and specificity of 81.22% in the training set and, respectively, 45.65% and 65.15% in the test sample. For men BMI, WC, HC, and WHC showed the best prediction with the lowest deviance (57.25, misclassification (.16, and the higher pseudo R2 (.46. This model had a sensitivity of 72% and specificity of 86.25% in the training set and, respectively, 58.38% and 69.70% in the test set. Finally, the result from the classification tree analysis was compared with traditional logistic regression, indicating that the former outperformed the latter in terms of predictive power.

    2004-03-01

    Full Text Available Abstract Background In most western countries 20% of adults have hypertension. Reports in the literature suggest that from 31 to 86% of treated patients are not at recommended target levels. However it is important to consider how we are determining whether targets are unmet and the degree to which they are unmet. Our underlying hypothesis is that white coat effect is partially responsible for the reported low rates of control of hypertension by primary care practitioners. Methods The study population consists of 1142 patients who are being assessed for enrolment in two community-based randomized controlled trials. Patients must have essential hypertension, be on antihypertensive medication, and must not have met their blood pressure targets. We are reporting on the proportion of patients who have not achieved target, and the degree to which they have not achieved their target. We also report on the mean daytime blood pressures on 24 hour ABPM and compare these to mean blood pressures found on the patients' charts. Results We identified 3284 patient charts of patients with hypertension. Of these, 1142 were determined to be "out of control" (did not achieve target and 436 agreed to undergo 24 hour ABPM for final determination of eligibility. Overwhelmingly (95.8% of the time it was the systolic blood pressure that was not under control. However, most of the patients who had not achieved target according to our criteria were within 10 mmHg of the recommended targets. Isolated systolic blood pressure was the best predictor of elevated mean daytime blood pressure on 24 hour ABPM. Conclusions At least 35% of patients had not achieved target blood pressure levels and this is primarily due to lack of control of systolic blood pressure. The best predictor of continuing hypertension on 24 hour ABPM was the mean systolic blood pressure on the patients chart. However, only 69% of patients who were uncontrolled according blood pressures recorded in the

    Blood pressure monitoring is an essential component of neonatal intensive care. We compared invasive and noninvasive (Dinamap, Marquette, and Dash) recordings in newborns and also noninvasive values obtained from upper and lower limbs. Infants\\' blood pressure was recorded every 6 hours for 72 hours using three noninvasive devices and compared with invasive readings taken simultaneously. Twenty-five babies were enrolled in the study, with birth weights of 560 to 4500 g and gestation 24 + 1 to 40 + 5 weeks. Three hundred thirty-two recordings were obtained. Comparison between invasive and noninvasive readings revealed that all three noninvasive monitors overread mean blood pressure. There was no significant difference between the cuff recordings obtained from the upper or lower limbs. All three noninvasive devices overestimated mean blood pressure values compared with invasive monitoring. Clinicians may be falsely reassured by noninvasive monitoring. Mean blood pressure values obtained from the upper and lower limb are similar.

For each session, the subjects were evaluated before and after intervention. In the pre-intervention period, blood pressure, forearm blood flow, and forearm vascular resistance were measured after 10 minutes of rest in the supine position. Thereafter, the subjects were taken to the gym to perform their exercise sessions or remained at rest during the same time period. Both S1 and S3 comprised a set of ten repetitions of ten exercises, with an interval of 90 seconds between exercises. Subsequently, the measurements were again performed at 10, 30, 50, 70, and 90 minutes of recovery (post-intervention in the supine position.Results: Post-exercise hypotension was greater in S3 than in S1 (systolic blood pressure, −26.5±4.2 mmHg versus −17.9±4.7 mmHg; diastolic blood pressure, −13.8±4.9 mmHg versus −7.7±5 mmHg, P<0.05. Similarly, forearm blood flow and forearm vascular resistance changed significantly in both sessions with an increase and decrease, respectively, that was more evident in S3 than in S1 (P<0.05.Conclusion: Resistance exercises with higher volume were more effective in causing post-exercise hypotension, being accompanied by an increase in forearm blood flow and a reduction of forearm vascular

    This paper discusses two kinds of regulation essential to the circulatory system: namely the regulation of blood flow and that of (systemic) arterial blood pressure. It is pointed out that blood flow requirements sub-serve the nutritional needs of the tissues, adequately catered for by keeping blood flow sufficient for the individual oxygen needs. Individual tissue oxygen requirements vary between tissue types, while highly specific for a given individual tissue. Hence, blood flows are distributed between multiple tissues, each with a specific optimum relationship between the rate of oxygen delivery (DO2) and oxygen consumption (VO2). Previous work has illustrated that the individual tissue blood flows are adjusted proportionately, where there are variations in metabolic rate and where arterial oxygen content (CaO2) varies. While arterial blood pressure is essential for the provision of a sufficient pressure gradient to drive blood flow, it is applicable throughout the arterial system at any one time. Furthermore, It is regulated independently of the input resistance to individual tissues (local arterioles), since they are regulated locally, that being the means by which the highly specific adequate local requirement for DO2 is ensured. Since total blood flow is the summation of all the individually regulated tissue blood flows cardiac inflow (venous return) amounts to total tissue blood flow and as the heart puts out what it receives cardiac output is therefore determined at the tissues. Hence, regulation of arterial blood pressure is independent of the distributed independent regulation of individual tissues. It is proposed here that mechanical features of arterial blood pressure regulation will depend rather on the balance between blood volume and venous wall tension, determinants of venous pressure. The potential for this explanation is treated in some detail. PMID:26782204

    Systolic blood pressure and heart rate measured at rest and during a standardized exercise test were analyzed in the cohort of middle-aged male employees followed-up an average of 17 years in the Paris Prospective Study I. The population sample selected for the analysis included 4,907 men who completed at least 5 minutes of bicycle ergometry, who had no heart disease at entry, and whose resting blood pressure was less than or equal to 180/105 mm Hg. Exercise-induced increase in systolic blood pressure was positively correlated with resting systolic blood pressure (r = 0.104, p less than 0.0001), whereas the correlation of exercise-induced heart rate increase with resting heart rate was negative (r = -0.169, p less than 0.001). Using Cox regression analysis with the inclusion of resting systolic blood pressure and heart rate; exercise-induced elevations of systolic blood pressure and heart rate; and controlling for age, smoking, total cholesterol, body mass index, electrical left ventricular hypertrophy, and sports activities, cardiovascular mortality was found to be associated with the systolic blood pressure increase (p less than 0.05), whereas no association with resting systolic blood pressure was found. Total mortality was predicted by resting systolic blood pressure and its elevation (p less than 0.01 for both) and by resting heart rate (p less than 0.0001). The heart rate increase did not contribute to death prediction. In conclusion, the magnitude of the exercise-induced increase of systolic blood pressure, but not of heart rate, may represent a risk factor for death from cardiovascular as well as noncardiovascular causes, independently of resting blood pressure and heart rate.

    Although epidemiological studies suggest that offspring of women with preeclampsia are at increased risk to higher blood pressures and cardiovascular disease, little is known about the nature of blood pressures between the mother and her offspring. As blood pressures comprise of both pulsatile (systolic blood pressure [SBP] and pulse pressure [PP]) and stable (diastolic blood pressure [DBP]) components, and they differ between central and peripheral sites, we sought to examine maternal peripheral and central blood pressure components in relation to offspring early childhood blood pressures. A prospective birth cohort of 567 Chinese, Malay, and Indian mother-offspring with complete blood pressure information were studied. Maternal brachial artery SBP, DBP, and PP were measured at 26 to 28 weeks gestation; and central SBP and PP were estimated from radial artery waveforms. Offspring brachial artery SBP, DBP, and PP were measured at 3 years of age. Associations between continuous variables of maternal blood pressures (peripheral SBP, DBP, PP, central SBP, and PP) and offspring blood pressures (peripheral SBP, DBP, and PP) were examined using multiple linear regression with adjustment for maternal characteristics (age, education level, parity, smoking status, alcohol consumption and physical activity during pregnancy, and pre-pregnancy BMI) and offspring characteristics (sex, ethnicity, BMI, and height at 3 years of age). In the multivariate models, offspring peripheral SBP increased by 0.08 (95% confidence interval 0.00-0.17, P = 0.06) mmHg with every 1-mmHg increase in maternal central SBP, and offspring peripheral PP increased by 0.10 (0.01-0.18, P = 0.03) mmHg for every 1-mmHg increase in maternal central PP. The relations of maternal-offspring peripheral blood pressures (SBP, DBP, and PP) were positive but not statistically significant, and the corresponding values were 0.05 (-0.03 to 0.13; P = 0.21), 0.03 (-0.04 to 0.10; P = 0.35), and 0.05 (-0

    In diagnostics and therapy control of cardiovascular diseases, detailed knowledge about the patient-specific behavior of blood flow and pressure can be essential. The only method capable of measuring complete time-resolved three-dimensional vector fields of the blood flow velocities is velocity-encoded magnetic resonance imaging (MRI), often denoted as 4D flow MRI. Furthermore, relative pressure maps can be computed from this data source, as presented by different groups in recent years. Hence, analysis of blood flow and pressure using 4D flow MRI can be a valuable technique in management of cardiovascular diseases. In order to perform these tasks, all necessary steps in the corresponding process chain can be carried out in our in-house developed software framework MEDIFRAME. In this article, we apply MEDIFRAME for a study of hemodynamics in the pulmonary arteries of five healthy volunteers. The study included measuring vector fields of blood flow velocities by phase-contrast MRI and subsequently computing relative blood pressure maps. We visualized blood flow by streamline depictions and computed characteristic values for the left and the right pulmonary artery (LPA and RPA). In all volunteers, we observed a lower amount of blood flow in the LPA compared to the RPA. Furthermore, we visualized blood pressure maps using volume rendering and generated graphs of pressure differences between the LPA, the RPA and the main pulmonary artery. In most volunteers, blood pressure was increased near to the bifurcation and in the proximal LPA, leading to higher average pressure values in the LPA compared to the RPA.

    Noninvasive 24-hour ambulatory blood pressure monitoring was performed in 17 normotensive and 19 preeclamptic pregnant women. The normotensive women showed a significant nightly decline in their systolic and diastolic blood pressure. In contrast, the preeclamptic women demonstrated either an attenuated circadian rhythm or no circadian rhythm at all. This result was even more pronounced in patients with severe hypertension, some of whom had a nocturnal increase in blood pressure in spite of being treated with antihypertensive drugs in an evening dose. The lack of nocturnal blood pressure decrease was also found 24 hours post partum. In summary, these results suggest that preeclamptic women are endangered by hypertensive emergencies mostly during the night. Therefore blood pressure controls should be extended into the night, and antihypertensive drugs should also be given in a sufficient evening dose. PMID:2214601

    Previous studies demonstrated that overexpression of angiotensinogen (AGT) in adipose tissue increased blood pressure. However, the contribution of endogenous AGT in adipocytes to the systemic renin-angiotensin system (RAS) and blood pressure control is undefined.

    Full Text Available Abstract Background Automatic measurement of arterial blood pressure is important, but the available commercial automatic blood pressure meters, mostly based on oscillometry, are of low accuracy. Methods In this study, we present a cuff-based technique for automatic measurement of systolic blood pressure, based on photoplethysmographic signals measured simultaneously in fingers of both hands. After inflating the pressure cuff to a level above systolic blood pressure in a relatively slow rate, it is slowly deflated. The cuff pressure for which the photoplethysmographic signal reappeared during the deflation of the pressure-cuff was taken as the systolic blood pressure. The algorithm for the detection of the photoplethysmographic signal involves: (1 determination of the time-segments in which the photoplethysmographic signal distal to the cuff is expected to appear, utilizing the photoplethysmographic signal in the free hand, and (2 discrimination between random fluctuations and photoplethysmographic pattern. The detected pulses in the time-segments were identified as photoplethysmographic pulses if they met two criteria, based on the pulse waveform and on the correlation between the signal in each segment and the signal in the two neighboring segments. Results Comparison of the photoplethysmographic-based automatic technique to sphygmomanometry, the reference standard, shows that the standard deviation of their differences was 3.7 mmHg. For subjects with systolic blood pressure above 130 mmHg the standard deviation was even lower, 2.9 mmHg. These values are much lower than the 8 mmHg value imposed by AAMI standard for automatic blood pressure meters. Conclusion The photoplethysmographic-based technique for automatic measurement of systolic blood pressure, and the algorithm which was presented in this study, seems to be accurate.

    Full Text Available Background: Worldwide prevalence of overweight and obesity is increasing and its consequences prompted the WHO to designate obesity as a global epidemic in 2002. Being overweight is a risk factor for significant illness, especially diabetes and hypertension in adult life. Objectives : To study the blood pressure and blood sugar levels and lifestyle parameters in adolescence and comparison with body mass index. Materials and Methods: In a prospective case control study, out of the 1000 screened, a total of 200 adolescents were considered out of which 100 were with high body mass index (BMI and the other 100 were with normal BMI. Height, weight, BMI, waist hip ratio (WHR, blood pressure (BP, BSL, and associated risk factors like physical activity, fast food consumption, and computer/television watching were measured and screened. Results and Observations: 109 (54.5% males and 91 (45.5% females were included. Maximum number [90 (45%] of adolescents screened were in the age group of 17-19 years, while 54 (27% and 56 (28% adolescents were in the age group of 10-13 years and 14-16 years, respectively. According to CDC charts 2000, prevalence of overweight was 24% which was double when compared to WHO charts 2007. There was significant difference in prevalence of obesity; according to CDC chart it was 26%, whereas according to WHO chart it was 39%. The difference in blood pressures between cases and controls as per both CDC and WHO charts was found to be statistically significant (P 0.05 with BMI. Conclusion: The adolescents seem to have become heavier owing to environmental influences on growth patterns. So, a consideration should be given to shift the cut-offs for overweight and obesity to higher BMI percentiles if recent growth charts are to be followed. Adolescents with a BMI above the 95 >th percentile (obese are most likely to have obesity-related health risks.

    1989-01-01

    In order to evaluate the antihypertensive effectiveness and interaction with ciclosporin A (CS-A) nitrendipine, a dihydropyridine derivative calcium entry blocking agent, was used in 16 (13 men, 3 women) hypertensive renal posttransplant patients followed by the Nephrology Department of Hacettepe University Hospital. The patients did not receive any antihypertensive drug for a 7-day period. They were then given 20 mg/day nitrendipine for 3 weeks. At the end of this period, mean (+/- SE) supine blood pressure fell from 163/108 +/- 3.6/1.87 to 141/87 +/- 3.8/2.2 mm Hg (p less than 0.01), while the heart rate was unchanged. 14 of 16 patients achieved full control of blood pressure levels with 20 mg/day nitrendipine, and only 2 patients needed a higher dosage of 30 mg/day (20 + 10 mg). After 3 weeks of treatment no significant variations in blood chemistry or renal functional parameters were noticed. There was also no difference between blood CS-A levels before and after treatment with nitrendipine (218.06 +/- 33 vs. 222.68 +/- 26 ng/ml, p greater than 0.05). We conclude that short-term therapy with nitrendipine in renal post-transplant patients does not appear to be harmful and longer term studies are needed to fully evaluate safety and efficacy of this drug. Because it influences neither blood chemistry nor renal functional parameters and blood CS-A level, it may be preferable to other calcium channel blocking agents in this group of patients.

    This study tested the hypothesis that limb venous responses to baroreceptor unloading are altered in individuals with high blood pressure (HBP) compared with normotensive (NT) controls. Calf venous compliance was assessed in 20 subjects with prehypertension and stage-1 hypertension (mean arterial pressure, MAP: 104±1 mm Hg) and 13 NT controls (MAP: 86±2 mm Hg) at baseline and during lower body negative pressure (LBNP), using venous occlusion plethysmography. Baroreflex sensitivity (BRS) was measured using the sequence technique and total peripheral resistance (TPR) was estimated from finger plethysmography. Baseline venous compliance was not different between groups, but the HBP group had lower baseline lnBRS (2.22±0.14 vs 2.7±0.18 ms mm Hg(-1)) and greater baseline TPR (3828±138 vs 3250±111 dyn sec(-1) cm(-5) m(2), Pcompliance was reduced in response to LBNP only in the NT group (Psec(-1) cm(-5) m(2), P<0.05). In conclusion, the early stages of hypertension are characterized by an attenuated venoconstrictor response to baroreceptor unloading, which may compensate for an exaggerated vasoconstrictor response and protect against further increases in blood pressure.

    Results of a study in which six supine resting subjects, wearing water-perfused suits, had body skin temperature controlled at 35 C for 30 min (control period), then rapidly increased to 40.5 C for 43 to 50 min (heating period) in a two-part experiment. In the first part of the experiment arterial mean pressure (MP) in three men was increased back to, or above control levels at the 30 to 35th min of heating by total occlusion of both legs for 8 to 10 min. Splanchnic blood flow (SBF), which had fallen from 1.4 to 0.9 L/min at occlusion, rose only 0.05 L/min during occlusion. Splanchnic vascular resistance (SVR) rose throughout heating and occlusion. In the second part of the experiment (three men) SBF fell despite a spontaneous rise in MP and aortic pulse pressure prior to leg occlusion. Cardiac output (CO) was measured just before, during and after occlusion. Occlusion raised MP 10 to 15 mm Hg and reduced CO only slightly. It is concluded that falling MP or aortic pulse pressure are not major causes of the splanchnic vasoconstriction in response to heating man.

    2003-01-01

    AIMS: In chronic renal failure, the clearance of most ACE inhibitors including enalapril is reduced. Hence, with conventional dosage, plasma enalaprilat may be markedly elevated. It is unclear whether this excess of drug exposure affords an improved control of blood pressure. The aim of the present...... study was to evaluate short-term blood pressure response to two different plasma levels of enalaprilat. METHODS: As part of an open, randomized, controlled trial of the effect of high and low dosage of enalapril on the progression of renal failure, short-term blood pressure response was evaluated. Data...... potassium concentrations at day 90 and patients in the low group experienced a slight increase in GFR. CONCLUSIONS: In moderate to severe chronic renal insufficiency the same degree of blood pressure control was achieved on low as well as moderate daily doses of enalapril. This was irrespective of...

    Watching television and playing video game being seated represent sedentary behaviours and increase the risk of weight gain and hypertension. We investigated the acute effects of violent and non-violent video-game playing on blood pressure (BP), appetite perception and food preferences. Forty-eight young, normal-weight men (age: 23.1±1.9 years; body mass index: 22.5±1.9 kg/m(2)) participated in a three-arm, randomized trial. Subjects played a violent video game, a competitive, non-violent video game or watched TV for 1 h. Measurements of BP, stress and appetite perception were recorded before a standardized meal (∼300 kcal) and then repeated every 15 min throughout the intervention. Violent video-game playing was associated with a significant increase in diastolic BP (Δ±s.d.=+7.5±5.8 mm Hg; P=0.04) compared with the other two groups. Subjects playing violent video games felt less full (P=0.02) and reported a tendency towards sweet food consumption. Video games involving violence appear to be associated with significant effects on BP and appetite perceptions compared with non-violent gaming or watching TV. PMID:24084510

    Diabetic nephropathy represents a condition frequently detected in current clinical practice characterized by a very high cardiovascular risk profile. Blood pressure reduction via antihypertension drug treatment represents a therapeutic approach capable of exerting favorable effects on renal and cardiovascular outcomes. The purpose of this article is to review the current literature and results of key clinical trials pertaining to blood pressure goals of antihypertension treatment in these patients. The pros and cons of a less or a more intensive blood pressure goal in diabetic nephropathy will be discussed, with particular emphasis on the cardiovascular and renal effects of each therapeutic strategy.

    Indirectly measured blood pressure at the wrist or upper arm was compared with directly measured values in the aortic arch during routinely performed diagnostic cardiac catheterization in 100 patients (31-80 years, mean 59.3 years, 60% males). The noninvasive measurements were carried out by oscillometric devices, NAiS Blood Pressure Watch for measurements at the wrist, and Hestia OZ80 at the upper arm. Systolic blood pressure measured at the wrist was 4.3 +/- 14.1 mm Hg, and the diastolic value 6.0 +/- 8.9 mm Hg higher than when measured at the aortic arch; the difference was significant in both cases. Correlation coefficients were 0.85 for systolic and 0.71 for diastolic blood pressure. In 16% of the patients the systolic blood pressure at the wrist differed more than +/- 20 mm Hg. The diastolic blood pressure at the wrist measured more than +/- 20 mm Hg higher than in the aorta in 5% of the patients. At the upper arm mean systolic values were not different to the aorta. The diastolic pressure was 9.3 +/- 9.8 mm Hg higher in the aorta than at the upper arm. To verify the accuracy of values measured with the NAiS Blood Pressure Watch compared with the standard technique at the upper arm, sequential measurements were made at wrist and ipsilateral upper arm in the same group of 100 patients. The systolic blood pressure at the left wrist was 3.4 +/- 13.3 mm Hg higher and the diastolic pressure 3.8 +/- 9.5 mm Hg lower than at the upper arm. Only 53% of systolic values lay within a range of +/- 10 mm Hg. The correspondence between wrist and upper arm values was better for diastolic blood pressure, the values differing by less than +/- 10 mm Hg in two-thirds of patients. Self-measurement of arterial blood pressure with an oscillometric device at the wrist can be recommended only in individual cases with a difference of simultaneously measured values at the upper arm of less than +/- 10 mm Hg for systolic and diastolic blood pressures.

    In normal pregnancy the circadian blood pressure rhythm is similar to that in the non-pregnant state, with the highest blood pressure values in the morning and the lowest at midnight. This rhythm is lost in patients with pre-eclampsia. Women with severe pre-eclampsia show a reversed circadian rhythm, with a nocturnal increase in blood pressure during the sleeping phase. Although the reasons for this nocturnal hypertension in severe pre-eclampsia are poorly understood, the results suggest that pre-eclamptic women are endangered by hypertensive emergencies, mostly at night. Therefore blood pressure measurement should be extended to the night, and antihypertensive treatment must be adapted to the demands of a reversed circadian rhythm in relevant subgroups of patients.

    Full Text Available Blood pressure checking and its theoretical knowledge are crucial to obtain reliable data in clinical examination. Although it is considered a simple technique to be learned and applied, it is not fully dealt with at physiotherapy university courses. Therefore, a wide range of mistakes and misinterpretations are likely to threaten treatment quality. This work aims to evaluate the theory background of physiotherapists for blood pressure measurement. From June to October 2002, 55 physiotherapists answered a 20- question multiple-choice questionnaire on general knowledge related to concepts, anatomy and physiology, suitable equipment, indirect measurement, blood pressure values, mistakes and misinterpretation factors related to blood pressure measurement. The results disclose faulty theory concepts in the sample studied, indicating the need of deeper approach to this complex theme during course and ongoing updating of professionals.

    Full Text Available BACKGROUND: Diurnal variations in the incidence of events such as heart attack and stroke suggest a role for circadian rhythms in the etiology of cardiovascular disease. The aim of this study was to assess the influence of the suprachiasmatic nucleus (SCN circadian clock on cardiovascular function. METHODOLOGY/PRINCIPAL FINDINGS: Heart rate (HR, blood pressure (BP and locomotor activity (LA were measured in circadian mutant (Vipr2(-/- mice and wild type littermates, using implanted radio-telemetry devices. Sleep and wakefulness were studied in similar mice implanted with electroencephalograph (EEG electrodes. There was less diurnal variation in the frequency and duration of bouts of rest/activity and sleep/wake in Vipr2(-/- mice than in wild type (WT and short "ultradian" episodes of arousal were more prominent, especially in constant conditions (DD. Activity was an important determinant of circadian variation in BP and HR in animals of both genotypes; altered timing of episodes of activity and rest (as well as sleep and wakefulness across the day accounted for most of the difference between Vipr2(-/- mice and WT. However, there was also a modest circadian rhythm of resting HR and BP that was independent of LA. CONCLUSIONS/SIGNIFICANCE: If appropriate methods of analysis are used that take into account sleep and locomotor activity level, mice are a good model for understanding the contribution of circadian timing to cardiovascular function. Future studies of the influence of sleep and wakefulness on cardiovascular physiology may help to explain accumulating evidence linking disrupted sleep with cardiovascular disease in man.

    Background Liquorice ingestion often elevates blood pressure, but the detailed haemodynamic alterations are unknown. We studied haemodynamic changes induced by liquorice consumption in 20 subjects versus 30 controls with average blood pressures of 120/68 and 116/64 mmHg, respectively. Methods Haemodynamic variables were measured in supine position before and after two weeks of liquorice consumption (daily glycyrrhizin dose 290–370 mg) with tonometric recording of radial blood pressure, pulse wave analysis, and whole-body impedance cardiography. Thirty age-matched healthy subjects maintaining their normal diet were studied as controls. Results Two weeks of liquorice ingestion elevated peripheral and central systolic and diastolic blood pressure (by 7/4 and 8/4 mmHg, 95% confidence intervals [CI] 2-11/1-8 and 3-13/1-8, respectively, P ClinicalTrials.gov NCT01742702 PMID:25153328

  9. Buffering blood pressure fluctuations by respiratory sinus arrhythmia may in fact enhance them: a theoretical analysis

    Buchner, Teodor; Gielerak, Grzegorz

    2010-01-01

    Using a three-compartment model of blood pressure dynamics, we analyze theoretically the short term cardiovascular variability: how the respiratory-related blood pressure fluctuations are buffered by appropriate heart rate changes: i.e. the respiratory sinus arrhythmia. The buffering is shown to be crucially dependent on the time delay between the stimulus (such as e.g. the inspiration onset) and the application of the control (the moment in time when the efferent response is delivered to the heart). This theoretical analysis shows that the buffering mechanism is effective only in the upright position of the body. It explains a paradoxical effect of enhancement of the blood pressure fluctuations by an ineffective control. Such a phenomenon was observed experimentally. Using the basis of the model, we discuss the blood pressure variability and heart rate variability under such clinical conditions as the states of expressed adrenergic drive and the tilt-test during the parasympathetic blockade or fixed rate atr...

    A high blood pressure level in adults is considered the single most important modifiable risk factor for global disease burden, especially those of cardiovascular (CV) origin such as stroke and ischemic heart disease. Because blood pressure levels have been shown to persist from childhood to adulthood, elevations in pediatric levels have been hypothesized to lead to increased CV burden in adulthood and, as such, might provide a window in the life course where primordial and primary prevention...

    High blood pressure is the major risk factor for cardiovascular disease. Low blood pressure control rates in Latin American populations emphasize the need for gathering evidence on effective therapies. To evaluate the effects of dietary interventions on blood pressure in Latin American populations. Systematic review. Electronic databases (MEDLINE/PubMed, Embase, Cochrane Library, CINAHL, Web of Science, Scopus, SciELO, LILACS and VHL) were searched and manual search for studies published up to April 2013 was performed. Parallel studies about dietary interventions in Latin American adult populations assessing arterial blood pressure (mm Hg) before and after intervention were included. Of the 405 studies identified, 10 randomized controlled trials were included and divided into 3 subgroups according to the proposed dietary intervention. There was a non-significant reduction in systolic blood pressure in the subgroups of mineral replacement (-4.82; 95% CI: -11.36 to 1.73) and complex pattern diets (-3.17; 95% CI: -7.62 to 1.28). Regarding diastolic blood pressure, except for the hyperproteic diet subgroup, all subgroups showed a significant reduction in blood pressure: -4.66 mmHg (95% CI: -9.21 to -0.12) and -4.55 mmHg (95% CI: -7.04 to -2.06) for mineral replacement and complex pattern diets, respectively. Available evidence on the effects of dietary changes on blood pressure in Latin American populations indicates a homogeneous effect of those interventions, although not significant for systolic blood pressure. Samples were small and the quality of the studies was generally low. Larger studies are required to build robust evidence.

    Background. Recent studies suggest that the daily intake of lemon (Citrus limon) has a good effect on health, but this has not been confirmed in humans. In our previous studies, it was observed that people who are conscious of their health performed more lemon intake and exercise. An analysis that took this into account was required. Methodology. For 101 middle-aged women in an island area in Hiroshima, Japan, a record of lemon ingestion efforts and the number of steps walked was carried out for five months. The change rates (Δ%) of the physical measurements, blood test, blood pressure, and pulse wave measured value during the observation period were calculated, and correlations with lemon intake and the number of steps walked were considered. As a result, it was suggested that daily lemon intake and walking are effective for high blood pressure because both showed significant negative correlation to systolic blood pressure Δ%. Conclusions. As a result of multiple linear regression analysis, it was possible that lemon ingestion is involved more greatly with the blood citric acid concentration Δ% and the number of steps with blood pressure Δ%, and it was surmised that the number of steps and lemon ingestion are related to blood pressure improvement by different action mechanisms.

    It is important to know about a sudden blood pressure change that occurs in everyday life and may pose a danger to human health. However, monitoring the blood pressure variation in daily life is difficult because a bulky and expensive sensor is needed to measure the blood pressure continuously. In this study, a new non-contact method is proposed to estimate the blood pressure variation using video images. In this method, the pulse propagation time difference or instantaneous phase difference is calculated between two pulse waves obtained from different parts of a subject's body captured by a video camera. The forehead, left cheek, and right hand are selected as regions to obtain pulse waves. Both the pulse propagation time difference and instantaneous phase difference were calculated from the video images of 20 healthy subjects performing the Valsalva maneuver. These indices are considered to have a negative correlation with the blood pressure variation because they approximate the pulse transit time obtained from a photoplethysmograph. However, the experimental results showed that the correlation coefficients between the blood pressure and the proposed indices were approximately 0.6 for the pulse wave obtained from the right hand. This result is considered to be due to the difference in the transmission depth into the skin between the green and infrared light used as light sources for the video image and conventional photoplethysmogram, respectively. In addition, the difference in the innervation of the face and hand may be related to the results. PMID:26737225

    Full Text Available Studies have shown that resistance exercise reduces 24-hour blood pressure to levels below resting values, although this is not a universal finding. The number of repetitions has been shown to influence this response. Thus, the aim of the study was to analyze the effects of resistance exercise performed until failure (UF on 24-hour blood pressure in hypertensive women. Thirteen hypertensive women underwent three experimental sessions in random order: UF, resistance exercise with repetitions before concentric failure (BF and control (C. Prior to and up to 24 hours after the sessions, cardiovascular variables, as well as the nocturnal fall in blood pressure, the morning surge, and the presence or absence of a blood pressure dip pattern were established using an ambulatory blood pressure monitor. In both wakefulness and sleep there was no significant difference among the three groups. However, after UF and C fewer patients presented a dip in blood pressure (46% and 38%, respectively compared BF (77%, p=0.047. In conclusion, the UF attenuated blood pressure dips at night in hypertensive patients.

    Full Text Available Abstract Background Disparities in health and healthcare are extensively documented across clinical conditions, settings, and dimensions of healthcare quality. In particular, studies show that ethnic minorities and persons with low socioeconomic status receive poorer quality of interpersonal or patient-centered care than whites and persons with higher socioeconomic status. Strong evidence links patient-centered care to improvements in patient adherence and health outcomes; therefore, interventions that enhance this dimension of care are promising strategies to improve adherence and overcome disparities in outcomes for ethnic minorities and poor persons. Objective This paper describes the design of the Patient-Physician Partnership (Triple P Study. The goal of the study is to compare the relative effectiveness of the patient and physician intensive interventions, separately, and in combination with one another, with the effectiveness of minimal interventions. The main hypothesis is that patients in the intensive intervention groups will have better adherence to appointments, medication, and lifestyle recommendations at three and twelve months than patients in minimal intervention groups. The study also examines other process and outcome measures, including patient-physician communication behaviors, patient ratings of care, health service utilization, and blood pressure control. Methods A total of 50 primary care physicians and 279 of their ethnic minority or poor patients with hypertension were recruited into a randomized controlled trial with a two by two factorial design. The study used a patient-centered, culturally tailored, education and activation intervention for patients with active follow-up delivered by a community health worker in the clinic. It also included a computerized, self-study communication skills training program for physicians, delivered via an interactive CD-ROM, with tailored feedback to address their individual

    2012-02-01

    Full Text Available Abstract Background Depression is known to be a risk factor for cardiovascular diseases but the underlying mechanisms remain unclear. Since recent preclinical evidence suggests that endogenous agonists of cannabinoid receptors (endocannabinoids are involved in both cardiovascular function and depression, we asked whether endocannabinoids correlated with either in humans. Results Resting blood pressure and serum content of endocannabinoids in ambulatory, medication-free, female volunteers with depression (n = 28 and their age- and ethnicity-matched controls (n = 27 were measured. In females with depression, both diastolic and mean arterial blood pressures were positively correlated with serum contents of the endocannabinoids, N-arachidonylethanolamine (anandamide and 2-arachidonoylglycerol. There was no correlation between blood pressure and endocannabinoids in control subjects. Furthermore, depressed women had significantly higher systolic blood pressure than control subjects. A larger body mass index was also found in depressed women, however, it was not significantly correlated with serum endocannabinoid contents. Conclusions This preliminary study raises the possibility that endocannabinoids play a role in blood pressure regulation in depressives with higher blood pressure, and suggests an interrelationship among endocannabinoids, depression and cardiovascular risk factors in women.

    Full Text Available Abstract Hypertension has a major associated risk for organ damage and mortality, which is further heightened in patients with prior cardiovascular (CV events, comorbid diabetes mellitus, microalbuminuria and renal impairment. Given that most patients with hypertension require at least two antihypertensives to achieve blood pressure (BP goals, identifying the most appropriate combination regimen based on individual risk factors and comorbidities is important for risk management. Single-pill combinations (SPCs containing two or more antihypertensive agents with complementary mechanisms of action offer potential advantages over free-drug combinations, including simplification of treatment regimens, convenience and reduced costs. The improved adherence and convenience resulting from SPC use is recognised in updated hypertension guidelines. Despite a wide choice of SPCs for hypertension treatment, clinical evidence from direct head-to-head comparisons to guide selection for individual patients is lacking. However, in patients with evidence of renal disease or at greater risk of developing renal disease, such as those with diabetes mellitus, microalbuminura and high-normal BP or overt hypertension, guidelines recommend renin-angiotensin system (RAS blocker-based combination therapy due to superior renoprotective effects compared with other antihypertensive classes. Furthermore, RAS inhibitors attenuate the oedema and renal hyperfiltration associated with calcium channel blocker (CCB monotherapy, making them a good choice for combination therapy. The occurrence of angiotensin-converting enzyme (ACE inhibitor-induced cough supports the use of angiotensin II receptor blockers (ARBs for RAS blockade rather than ACE inhibitors. In this regard, ARB-based SPCs are available in combination with the diuretic, hydrochlorothiazide (HCTZ or the calcium CCB, amlodipine.

    Full Text Available To compare the 24-hour (24h effects on intraocular pressure (IOP and cardiovascular parameters of timolol 0.5% and bimatoprost 0.01% in open angle glaucoma and ocular hypertensive subjects.In this prospective, randomized, double masked, crossover, clinical trial, after washout from previous medications enrolled subjects underwent 24h IOP, blood pressure (BP and heart rate (HR measurements and were randomized to either topical bimatoprost 0.01% at night plus placebo in the morning or to timolol 0.5% bid. After 8 weeks of treatment a second 24h assessment of IOP, BP and HR was performed and then subjects switched to the opposite treatment for additional 8 weeks when a third 24h assessment was performed. The primary endpoint was the comparison of the mean 24h IOP after each treatment. Secondary endpoints included the comparisons of IOP at each timepoint of the 24h curve and the comparison of BP, HR, ocular perfusion pressure and tolerability.Mean untreated 24h IOP was 20.3 mmHg (95%CI 19.0 to 21.6. Mean 24h IOP was significantly lower after 8 weeks of treatment with bimatoprost 0.01% than after 8 weeks of treatment with timolol 0.5% bid (15.7 vs 16.8 mmHg, p = 0.0003. Mean IOP during the day hours was significantly reduced from baseline by both drugs while mean IOP during the night hours was reduced by -2.3 mmHg (p = 0.0002 by bimatoprost 0.01% plus placebo and by -1.1 mmHg by timolol 0.5% bid (p = 0.06. Timolol 0.5% significantly reduced the mean 24h systolic BP from baseline, the diastolic BP during the day hours, the HR during the night hours, and the mean 24h systolic ocular perfusion pressure.Both Bimatoprost 0.01% and Timolol 0.5% are effective in reducing the mean 24h IOP from an untreated baseline but Bimatoprost 0.01% is more effective than timolol 0.5% throughout the 24h.

    Objective To observe blood pressure change with age in salt-sensitive teenagers whose salt sensitivity were determined by repeated testing.Methods Salt sensitivity was determined through intravenous infusion of normal saline combined with volume-depletion by oral diuretic furosemide in 55 teenagers. After five years, salt sensitivity was re-examined and subject blood pressure was followed up. Blood pressure changes in salt-sensitive teenagers were compared to that of non-salt sensitive teenagers over five years.Results After 5 years, the repetition rate of salt sensitivity determined by intravenous saline loading is 92.7%. In teenagers with salt sensitivity on the baseline, both the systolic blood pressure increments and increment rates were much higher than non-salt sensitive teenagers (12.7±12.1 mmHg vs. 2.8±5.2 mmHg, P< 0.01; 12.2%± 12.0% vs. 2.5% ±4.4%, P< 0.001,respectively). There was a similar trend for diastolic blood pressure (8.4 ± 6.4 mmHg vs. 3.7 ± 6.4 mmHg, P = 0.052; 13.2% ±10.6 % vs. 6.8%± 10.1%, P = 0.053, respectively).Conclusions Salt sensitivity determined by intravenous saline loading showed good reproducibility. Blood pressure increments with age were much higher in salt-sensitive teenagers than non-salt sensitive teenagers, especially in terms of systolic blood pressure.

  2. Blood pressure standards for Saudi children and adolescents

    International Nuclear Information System (INIS)

    Blood pressure levels may vary in children because of genetic, ethnic and socioeconomic factors. To date, there have been no large national studies in Saudi Arabia on blood pressure in children. Therefore, we sought to establish representative blood pressure reference centiles for Saudi Arabian children and adolescents. We selected a sample of children and adolescents aged from birth to 18 years by multi-stage probability sampling of the Saudi population. The selected sample represented Saudi children from the whole country. Data were collected through a house-to-house survey of all selected households in all 13 regions in the country. Data were analyzed to study the distribution pattern of systolic (SBP) and diastolic blood pressure (DBP) and to develop reference values. The 90th percentile of SBP and DBP values for each age were compared with values from a Turkish and an American study. A total of 16 226 Saudi children and adolescents from birth to 18 years were studied. Blood pressure rose steadily with age in both boys and girls. The average annual increase in SBP was 1.66 mm Hg for boys and1.44 mm Hg for girls. The average annual increase in DBP was 0.83 mm Hg for boys and 0.77 mm Hg for girls. DBP rose sharply in boys at the age of 18 years. Values for the 90th percentile of both SBP and DBP varied in Saudi children from their Turkish and American counterparts for all age groups. Blood pressure values in this study differed from those from other studies in developing countries and in the United States, indicating that comparison across studies is difficult and from that every population should use their own normal standards to define measured blood pressure levels in children.

    This study examined the role of ethnicity on the aerobic fitness, blood pressure, and selected blood chemistry values of women. One hundred twenty-four females (mean age 41.37 +/- 9.0) were medically Examined at the NASA/Johnson Space Center occupational health clinic. Ethnic groups consisted of 23 Black (B), 18 Hispanic (H) and 83 Non-minority (NM). Each woman had a maximum Bruce treadmill stress test (RER greater than or = 1.1) and a negative ECG. Indirect calorimetry, skinfolds, self-report physical activity (NASA activity scale), seated blood pressure, and blood chemistry panel determined VO2max, percent fat, level of physical activity, blood pressure and blood chemistry values. ANOVA revealed that the groups did not differ (p greater than 0.05) in age, VO2 max, weight, percent fat, level of physical activity, total cholesterol, or HDL-C. However, significant differences (p greater than 0.05) were noted in BMI, diastolic blood pressure, and blood chemistries. BMI was 3.17 higher in H than in NM; resting diastolic pressures were 5.69 and 8.05 mmHg. lower in NM and H than in B; triglycerides were 48.07 and 37.21 mg/dl higher in H than in B and NM; hemoglobin was .814 gm/dl higher in NM than B; fasting blood sugar was 15.41 mg/dl higher in H than NM; The results of this study showed that ethnic groups differed in blood pressure and blood chemistry values but not aerobic fitness or physical activity. There was an ethnic difference in BMI but not percent fat.

    We investigated the relationship between workplace supervisory social interactions and blood pressure outcomes using hourly diary entries and ambulatory blood pressure data from an experience sampling study of 55 long-term care employees. After accounting for relevant cardiovascular controls, significant effects of supervisory interactions on cardiovascular reactivity and recovery were found. Multilevel analyses revealed that negatively perceived supervisory interactions predicted higher systolic blood pressure at work (B = -1.59, p < .05, N observations = 422). Using time-lagged hierarchical regression analyses, the average perceived valence of supervisory interactions at work predicted average systolic blood pressure recovery after work (B = -14.52, p < .05, N = 33). Specifically, negatively perceived supervisory interactions at work predicted poorer cardiovascular recovery after work. Suggestions for improving practices in organizations and in experience sampling research are discussed. PMID:26641481

    Full Text Available Several epidemiologic studies have reported that exposure to noise is associated with cardiovascular disease. The increased body weight is often associated with metabolic as well as increased blood pressure. The aim of this study is to investigate the correlation between the elevation of blood pressure and serum leptin hormones due to the effects of noise in the work place. A total of 80 volunteer males where included in this study with an age range between of 20 and 45 years, they were divided in two groups equally, the 1 st group were exposed to noise in the workplace while the 2 nd group were not. The individual noise exposure was determined by using a sound level meter. The range of noise was 80-100 dBA. Body Mass Index was also taken for each individual by a standard measure, blood pressure was measured by OMRON sphygmomanometer and serum leptin was measured through venous blood sample analysis enzyme linked immunosorbent assay. Spearman rank order correlation was used to examine the correlations between Blood pressure value (Systolic, Diastolic and Leptin. All the relationships between parameters showed a positive correlation. Systolic and diastolic blood pressure values had a significant correlation to leptin hormone level in comparison to the control. There was a significant relation between leptin and blood pressure. leptin effects on the sympathetic nervous system may provide a partial explanation. Therefore, Leptin might have diverse cardiovascular actions.

    As the central pacemaker, the suprachiasmatic nucleus (SCN) has long been considered the primary regulator of blood pressure circadian rhythm; however, this dogma has been challenged by the discovery that each of the clock genes present in the SCN is also expressed and functions in peripheral tissues. The involvement and contribution of these peripheral clock genes in the circadian rhythm of blood pressure remains uncertain. Here, we demonstrate that selective deletion of the circadian clock transcriptional activator aryl hydrocarbon receptor nuclear translocator-like (Bmal1) from smooth muscle, but not from cardiomyocytes, compromised blood pressure circadian rhythm and decreased blood pressure without affecting SCN-controlled locomotor activity in murine models. In mesenteric arteries, BMAL1 bound to the promoter of and activated the transcription of Rho-kinase 2 (Rock2), and Bmal1 deletion abolished the time-of-day variations in response to agonist-induced vasoconstriction, myosin phosphorylation, and ROCK2 activation. Together, these data indicate that peripheral inputs contribute to the daily control of vasoconstriction and blood pressure and suggest that clock gene expression outside of the SCN should be further evaluated to elucidate pathogenic mechanisms of diseases involving blood pressure circadian rhythm disruption.

  11. Pathology influences blood pressure change following vagal stimulation in an animal intubation model.

    Directory of Open Access Journals (Sweden)

    Peter Jones

    Full Text Available PURPOSE: The haemodynamic response to critical care intubation is influenced by the use of sedation and relaxant drugs and the activation of the vagal reflex. It has been hypothesized that different disease states may have a contrasting effect on the cardiovascular response to vagal stimulation. Our objective was to determine whether the blood pressure response to vagal stimulation was modified by endotoxaemia or hypovolaemia. METHODS: New Zealand White rabbits were anaesthetised with urethane before tracheotomy. The exposed left Vagus nerve of randomised groups of control (n = 11, endotoxin (n = 11, 1 mg/kg, hypovolaemia 40% (n = 8 and hypovolaemia 20% (n = 8 rabbits were subjected to 10 Hz pulsed electrical stimulations of 25 s duration every 15 min. Haemodynamic parameters were recorded from a catheter in the right carotid artery connected to an iWorx monitor. Serum catecholamines were measured every 30 min using reverse-phase ion-pairing liquid chromatography. The change in blood pressure after vagal stimulation was compared to controls for one hour after the first death in the experimental groups. RESULTS: 29% of the rabbits died in the hypovolaemia 40% group and 27% in the endotoxin group. One rabbit died in the hypovolaemia 40% group before vagal stimulation and was excluded. Following electrical stimulation of the Vagus nerve there was a fall in blood pressure in control rabbits. Blood pressure was conserved in the hypovolaemic rabbits compared to controls (p<0.01. For the endotoxaemic rabbits, there was a non-significant trend for the mean blood pressure to decrease more than the controls. Serum catecholamines were significantly raised in both the hypovolaemic and endotoxaemic rabbits. CONCLUSIONS: Pathology may contribute to modifications in blood pressure when vagal activation occurs. Patients who are either already vasoconstricted, or not vasoplegic, may be less at risk from intubation-related vagally mediated

    Full Text Available Liquorice ingestion often elevates blood pressure, but the detailed haemodynamic alterations are unknown. We studied haemodynamic changes induced by liquorice consumption in 20 subjects versus 30 controls with average blood pressures of 120/68 and 116/64 mmHg, respectively.Haemodynamic variables were measured in supine position before and after two weeks of liquorice consumption (daily glycyrrhizin dose 290-370 mg with tonometric recording of radial blood pressure, pulse wave analysis, and whole-body impedance cardiography. Thirty age-matched healthy subjects maintaining their normal diet were studied as controls.Two weeks of liquorice ingestion elevated peripheral and central systolic and diastolic blood pressure (by 7/4 and 8/4 mmHg, 95% confidence intervals [CI] 2-11/1-8 and 3-13/1-8, respectively, P<0.05, and increased extracellular volume by 0.5 litres (P<0.05 versus controls. Also augmentation index adjusted to heart rate 75/min (from 7% to 11%, 95% CI for change 0.3-7.5, P<0.05 and aortic pulse pressure (by 4 mmHg, 95% CI 1-7, P<0.05 were elevated indicating increased wave reflection from the periphery. In contrast, peripheral (-3/-0.3 mmHg and central blood pressure (-2/-0.5 mmHg, aortic pulse pressure (-1 mmHg, and augmentation index adjusted to heart rate 75/min (from 9% to 7% decreased numerically but not statistically significantly without changes in extracellular volume in the control group. Heart rate, systemic vascular resistance, cardiac output, and pulse wave velocity did not differ between the groups.Two weeks of daily liquorice consumption increased extracellular volume, amplified pressure wave reflection from the periphery, and elevated central systolic and diastolic blood pressure.EU Clinical Trials Register EudraCT 2006-002065-39 ClinicalTrials.gov NCT01742702.

  14. Effect of antioxidant rich diets on lipid profile and blood pressure in cardiovascular patients

    International Nuclear Information System (INIS)

    A sample of 200 patients was randomly selected and interviewed. Various data related to their food consumption in previous weeks and other behavioral attitudes were recorded. Their blood pressure was measured and blood was analyzed for total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and triglycerides (TG). Spearman's correlation coefficient was worked out between blood pressure, serum lipid parameters and tea, vitamin C and fibre intake. Tea showed significant correlation with diastolic blood pressure (DBP) (-0.2373; P<0.02), systolic blood pressure (SBP) (-0.2299; P<0.02) and TC (-0.3454; P<0.01). Vitamin C showed a negatively significant correlation with TC (-0.4676; P<0.01), and LDL-C (-2661; P<0.01) and significant positive correlation with HDL-C (+0.2227; P < 0.05). The tea intake was found strongly correlated with blood pressure as compared to vitamin C, while vitamin C had stronger correlation with TC as compared to tea intake. Fibre was not found significantly correlated with any of the studied parameters. A 30-day control trial on 50 subjects revealed that antioxidant therapy during fat-restricted diet period significantly affected blood pressure and serum lipids. Comparative effect showed that lemon juice showed best results. Lemon juice decreased DBP, SBP, TC, TG and increased HDL-C, while tea added with lemon only significantly decreased DBP, SBP and TC. Salad, especially onion, only improved HDL-C and LDLC levels. Vitamin C supplement also significantly lowered DBP, SBP, TC, LDL-C and TG. Tea had negative correlation with blood pressure and TC, while vitamin C has showed relationship with TC, LDL-C and positive with HDL-C. It is conceivable, therefore, that dietary antioxidants cause a significant improvement in blood pressure and serum lipids than vitamin C supplement and simple fat-restricted diets. (author)

    Full Text Available Elevated blood pressure (BP is one of the most important risk factors for cardiovascular (CV morbidity and mortality, and BP lowering is associated with reduction of coronary events. Despite this, less than one-third of hypertensive patients in Europe have adequate BP control. Improvement of the rates of adequate BP control and thereby a reduction of CV morbidity and mortality, currently represent a major challenge in the daily clinical practice. Many patients require two or more antihypertensives to achieve guideline-recommended BP targets. Findings from different studies have demonstrated that the fixed-dose combination (FDC perindopril/amlodipine is an effective and well tolerated treatment in patients uncontrolled with monotherapy, and in patients inadequately managed on another combination therapy. The perindopril/amlodipine FDC provides good rates of BP control in daily clinical practice. These good rates of BP control could be ex- plained by the synergistic mode of action of the two components, leading to enhanced BP lowering and reduced side effects, which may have a positive impact on treatment adherence. Krka’s perindopril/amlodipine FDC is available in the full range of doses, providing a flexible and effective treatment of hypertension.

    Recently, the Action to Control Cardiovascular Risk in Diabetes (ACCORD) blood pressure (BP) trial enrolled 4733 participants with type 2 diabetes and randomized them to a target systolic blood pressure (SBP) of less than 120 mm Hg or 140 mm Hg. Despite the significant difference in the achieved SBP, there was no significant difference in the incidence of primary outcomes. Based on this evidence, the target SBP for diabetics has been revised in the majority of major guidelines. However, there is a steeper association between SBP and stroke in Asians than other ethnicities, with stroke being the leading cause of cardiovascular mortality. This suggests that target BP in the Asian region should be tailored towards prevention of stroke. In the ACCORD study, the intensive BP treatment was associated with significant reductions in both total stroke and non-fatal stroke. The results from the ACCORD study are supported by a subgroup analysis from the ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial (ONTARGET) study, which showed that, in diabetic patients, the risk of stroke continues to decrease to a SBP value of 115 mm Hg with no evidence of J curve. As diabetes is highly associated with underlying coronary artery disease, there is a justified concern for adverse effects resulting from too much lowering of BP. In a post hoc analysis of 6400 diabetic subjects enrolled in the International Verapamil SR-Trandolapril (INVEST) study, subjects with SBP of less than 110 mm Hg were associated with a significant increase in all-cause mortality. In the ONTARGET study, at any levels of achieved SBP, diastolic blood pressure (DBP) below 67 mm Hg was associated with increased risk for cardiovascular outcomes. As such, a prudent approach would be to target a SBP of 130-140 mm Hg and DBP of above 60 mm Hg in diabetics with coronary artery disease. In conclusion, hypertension, in association with diabetes, has been found to be significantly correlated

    Arterial volume clamping uses external compression of an artery to provide continuous non-invasive measurement of arterial blood pressure. It has been assumed that mean arterial pressure (MAP) corresponds to the point where unloading leads to the maximum oscillation of the arterial wall as reflected by photoplethysmogram (PPG), an assumption that has been challenged. Five subjects were recruited for the study (three males, mean age (SD) = 32 (15) years). The PPG waveform was analysed to identify the relationship between the external compressing pressure, PPG pulse amplitude and MAP. Two separate tests were carried out at compression step intervals of 10 mmHg and 2 mmHg, respectively. No significant differences were found between the two tests. The bias between the compressing pressure and the MAP was -4.7 ± 5.63 mmHg (p < 0.001) showing a normal distribution. Further research is needed to identify optimal algorithms for estimation of MAP using PPG associated with arterial compression. PMID:25429784
