Filter by:The investigators are proposing that individuals with elevated levels of NT-proBNP are resistant to natriuretic peptides and are unable to handle sodium loads and maintain optimal blood pressure values.The investigators will test this hypothesis by comparing the blood pressure response to low and high salt diets in individuals with pre- or hypertension and who have normal or elevated levels of NT-proBNP. The investigators expect that blood pressure values in those with normal levels of NT-proBNP will not change with high salt diets, whereas, in those with elevated levels of NT-proBNP, blood pressure values will increase significantly when exposed to high salt diets.
The purpose of the study is to understand the origins of differential response to beta-blockers in African-Americans and may provide insight regarding racial differences in cardiovascular risk.
The purpose of this RCT which will be performed in 60 healthy adults is I. To assess the training effects of 8 weeks of isometric handgrip exercise on BP; and to test whether it yields at least similar effects on BP compared to current exercise recommendations. II. To assess whether isometric handgrip training yields larger BP reductions beyond the supervised training period at 6 months of follow-up. III. To determine whether changes in BP following acute exercise and chronic training can be explained by changes in important physiological mechanisms known to mediate or to be associated with BP?
This study will investigate the effect of a nitric oxide supplementation product, Neo40 Daily®, on blood pressure in pre-hypertensive and mildly hypertensive adults. Subjects will take 2 lozenges per day 12 hours apart for 8 weeks. Half of the subjects will receive Neo40 Daily® and the other half of the subjects will receive placebo.
This study is intended for inactive, middle-aged adults with untreated pre-hypertension who live in the Urbana-Champaign area, who are interested in a comprehensive program designed to enhance physical activity & reduce blood pressure. All participants will be asked to engage in a program developed in accordance with American Heart Association's recommendations. Specifically, the program will encourage and support lifestyle behavior changes such as quitting smoking, eating heart-healthy food, and reducing excessive alcohol, in addition to weekly exercise. The exercise program will involve a 14-week aerobic training program (3 weekly sessions, scheduled at study participants' convenience), and 2 pre- and 2-post-testing sessions.
Hypertension affects about 30% of the United Kingdom population and is causally implicated in the aetiology of renal disease, cardiovascular disease and stroke. Ageing, obesity, a poor diet and low levels of physical activity are all risk factors. Studies have shown that adherence to a Mediterranean diet is protective against hypertension and its associated morbidities; olive oil is believed to be a key beneficially bioactive component of that diet. As a source of lipids olive oil is an unremarkable blend of monounsaturated, polyunsaturated and saturated fatty acids; it is however rich in phenolic compounds, principally oleuropein and hydroxytyrosol, which may be of benefit to health. A recent randomised intervention trial in predominantly hypertensive volunteers showed that adherence to a Mediterranean diet supplemented with extra virgin olive oil, reduced blood pressure and other measures of cardiovascular disease risk. Olive phenolics can be extracted cheaply from the waste products of olive oil manufacture, such as the plant leaf and these are used as dietary supplements. In intervention studies in hypertensive or borderline hypertensive patients, olive leaf extract consumption has been shown to reduce blood pressure. Another intervention with established efficacy for improving blood pressure is to increase physical activity. The 'Start Active, Stay Active', Chief Medical Officers report on physical activity recommends that adults achieve 150 minutes of moderate intensity physical activity per week, while data in that report suggest that fewer than 40% of adult men and 30% of adult women achieve these targets. Adherence to the physical activity guidelines may in fact be much worse in sub-sections of the population at higher risk of hypertension. From a public health perspective, holistic guidelines for the prevention of hypertension, or its early diagnosis and management, based around a healthy diet and lifestyle are preferable to pharmaceutical intervention. Lifestyle interventions are economically favourable and they come with fewer side effects and perhaps wider health benefits than antihypertensive drugs. The aim of the study is to evidence the synergistic benefits of consuming plant (and specifically olive) phenolics alongside achieving the recommended guidelines for physical activity in individuals with elevated blood pressure.
In this study we will assess the effects of bioactive peptide rich wheat products on blood pressure and estimated cardiovascular disease risk. This will be a pilot, explorative, cross-over, randomized double-blind 2 groups x 2-arms controlled, clinical trial. The intervention will be based on commercially-packaged pasta, which will appear and taste the same; (i) low dose bioactive peptides vs. (ii) high dose bioactive peptides. Inclusion Criteria will be: Male and female non-diabetic adult volunteers at increased estimated CV risk (ESC/EAS SCORE) with SBP 130-139 mmHg and/or DBP 85-90 mmHg); Age included between 40 and 70 years old; Primary prevention for CVD but otherwise in good general health and have had no major illness in the previous 6-months; Volunteer providing their signed and dated informed consent form. Exclusion Criteria will be: Severe medical illness/chronic disease/gastrointestinal pathology (e.g. coeliac disease); Secondary prevention for CVD; Treatment with drugs potentially affecting BP (including antihypertensive drugs) or other related CV risk factors; Consumption of nutraceuticals, botanical extracts or other vitamin supplements; Volunteer diagnosed as being hypertensive A total of 60 participants will be recruited and following adherence to a standardized diet for a 4-week period, will be randomly assigned to complete one of 2 treatment sequences by consuming a prescribed quantity of pasta products for a 4-week period followed by a 4-week washout before random assignment to the 2nd treatment. The Primary Outcome will be the modification of office blood pressure (assessed by systolic and diastolic BP, pulse and mean pressure (mean of 3 standing & sitting measures) and 24-hour blood pressure. Additional outcomes include: Anthropometric parameters (Weight, WC, HC, WC/HC, ICO, BMI), Glucose and Lipid profile (TC, LDL-C, HDL-C, TG, non-HDL cholesterol, risk ratios), Estimated CVD risk changes (EAS/ESC SCORE Charts), Measures of vascular health (FMD, PWA, PWV, Aix), Liver and renal functionality biomarkers, 24-h urine collection at baseline of treatment phase 1 and endpoint of the final phase will be analysed to account for potential confounding of urinary sodium excretion (intake) As required by the GCPs and GLPs, all the SOPs have already been established and all the personnel to be involved in the study is continuously trained in trials with similar outcomes
The purpose of this research study is to evaluate the effects of intermittent fasting in subjects that are eating a Mediterranean diet or a Western diet. This study is part of ongoing research in the prevention and treatment of age-related diseases at Washington University School of Medicine.
Arterial dysfunction contributes to the development of cardiovascular disease (CVD), which is currently afflicting millions of individuals. The use of the amino acid L-citrulline has been suggested as a potential aid for the treatment of CVD by increasing endothelial production of Nitric Oxide (NO). Whole body vibration (WBV) is new and effective form of exercise that is feasible for clinical populations and has been proven to decrease blood pressure (BP) and arterial stiffness and increase muscle mass and strength. Therefore, the purpose of this study was to investigate if the combination of WBV training (WBVT) plus L-citrulline supplementation would induce positive additive effects and would be an effective means to ameliorate arterial stiffness, endothelial function, BP and muscle strength/mass in postmenopausal women.
We propose a novel intervention for reducing BP that could have a preferential impact in patients with hyperuricemia and gout. There is a great need for new anti-hypertensives, particularly among those with gout. The proposed study is novel in its plans to investigate the physiologic mechanisms through which urate contributes to vascular disease and by which ULT may contribute to BP reduction. Also innovative, we will: 1) determine to what extent the described benefit of lowering serum urate extends beyond the adolescent population previously studied into young adults, 2) test whether a urate-lowering approach will benefit individuals that do not yet meet the current definition of hyperuricemia and do not have gout, and 3) begin to explore potential mechanisms for the higher prevalence of hypertension among African-Americans. If successful, this work could translate to the standard of clinical care and to health care recommendations for the population as a whole.
