NCT04085562
Hypertension is highly prevalent in hemodialysis (HD) patients and leads to increased morbidity and mortality due to cardiovascular disease(CVD). Left ventricular hypertrophy (LVH) is both a manifestation of hypertension caused end-organ damage and an independent risk factor for CVD. Evidence shows that Beta-blockers, especially of low dialyzability decrease risk of CVD and mortality. Calcium channel blockers (CCBs) were also shown to effectively control BP in the volume expanded state and reduce cardiovascular disease risk. Asymmetric dimethyl arginine (ADMA) is a uremic toxin that decreases NO synthesis and is correlated to LVH, carotid intimal thickness (CIT), CVD, and mortality. Amlodipine is shown in one study to significantly reduce ADMA level in HD patients. The purpose of this study is to determine the effect of calcium channel blocker Amlodipine compared to Beta-blocker Bisoprolol on regression of LVH, reduction of ADMA plasma level and on BP control among hypertensive patients on HD.
NCT00005143
To conduct a large-scale demonstration and education project designed to evaluate the feasibility and effectiveness of long-term community health education directed toward lowering cardiovascular disease risk, morbidity, and mortality. Targeted risk factors included general lifestyle, smoking, blood pressure, nutrition and weight, and exercise. The program was evaluated by biennial cross-sectional independent surveys, longitudinal studies, and morbidity and mortality surveillance.
NCT00979732
In this research study, the investigators are interested in learning how extracts from grape seeds can help those individuals with high blood pressure. The investigators also hope to learn how grape seed extract effects your blood and cell functions. The grape seed extract the investigators will use in the study will be provided either in a beverage or a capsule form and is currently available on the market. This study is also using a placebo; therefore the treatment subjects receive may or may not contain the grape seed extract. The purpose of this study is to determine if the grape seed extract (GSE) will lower blood pressure in people with slightly high blood pressure (Pre-Hypertension).
NCT00412113
The purpose of this study is to investigate whether an aggressive multi-risk factor management strategy (Caduet plus therapeutic lifestyle changes (TLC) regimen) will result in greater percentage of patients achieving blood pressure and low density lipoprotein cholesterol (LDL-C) goals compared with a Joint National Committee 7/ National Cholesterol Education Program Adult Treatment Panel III (JNC 7/NCEP ATP III) guideline-based approach (Norvasc plus TLC regimen) after 6 weeks of treatment in primary prevention subjects with hypertension and additional risk factors, including dyslipidemia.
NCT00415623
The changes in the trough systolic blood pressure from the baseline were assessed after 8 weeks of double-blind treatment with amlodipine 10 mg or amlodipine 5 mg
NCT03947996
High blood pressure is a leading risk factor for cardiovascular disease. Traditionally, one of the ways to treat or prevent high blood pressure is to prescribe aerobic exercise training (i.e.brisk walking). Previous studies have shown that stretching is also very effective for reducing blood pressure. This is an exciting possibility because if stretching is more effective, it would change the way exercise is prescribed to people with elevated blood pressure. This study will now assess 20 individuals in a supervised stretching or walking program five days per week for 8 weeks to determine for certain whether stretching is superior for reducing blood pressure. This research will contribute to recommendations about the most effective exercise programs for reducing blood pressure and risk of cardiovascular disease.
NCT04682015
WeChat is the largest and most popular social media platform in China, In this study, investigators will evaluate the use of management program delivered via WeChat platform in patients with hypertension.
NCT04746118
The purpose of this study is to evaluate the effectiveness of diet change and other non-pharmacological treatments which includes physical activity and integrative therapies oriented to reduce the blood pressure in hypertensive patients.
NCT04585555
The Accuryn Registry Study is an open-ended, global, multi-center, retrospective and prospective, single-arm data collection study with an FDA cleared device. The target population are cardiovascular surgery patients. Physiologic data measurements will be collected from enrolled subjects using electronic medical records and data streams via the Accuryn Monitoring System.
NCT04463745
Patients with end stage liver disease have varying degrees of intra-abdominal hypertension (IAH) due to the presence of ascites. The perioperative events may either relieve or aggravate the intra-abdominal pressures. Intra-abdominal hypertension has damaging effect on various organ systems. There is an increase in intracranial pressures and a decrease in cerebral perfusion pressures associated with IAH . In the heart, there is an increase of right atrial pressures, increase in systemic vascular resistance and decrease in cardiac output . Pulmonary complications include increase in the peak, mean and plateau airway pressures, with decreased compliance . Renal dysfunction is an early effect of raised intra-abdominal pressure, resulting from decreased renal blood flow, shunting of blood to the medulla, mechanical compression of the kidneys and increased pressures in the renal veins . We would study the intra-abdominal pressures in liver transplant recipients and record hemodynamic, respiratory, cardiac and renal function prospectively. Follow up data for 6 days for neurological, respiratory, cardiac and renal complications will be collected, along with hospital stay, ICU stay and mortality. The association between intra-abdominal pressures and these outcomes will be analysed.
NCT02342808
This study will examine the effects of lifestyle intervention on fitness, dietary habits, and body weight in patients with resistant hypertension (RH). Patients will be randomized to either a 4-month adjunctive lifestyle intervention designed to lower BP that will be delivered in a center-based CR program (C-LIFE), or to standardized education and physician advice (SEPA) designed to promote the same healthy behaviors and reflecting the current highest possible standard of care for promoting a healthy lifestyle in RH.
NCT03726710
The recently published LA Barbershop in the New England Journal of Medicine (Victor et al. N Engl J Med 2018; 378: 1291-301) solid evidence of the efficacy of a pharmacist-led medication management intervention to reduce blood pressure in black men that patronize barbershops. One of the most significant logistical inefficiencies of the LA Barbershop Study was the amount of time the pharmacists spent driving for face-to-face visits with participants. On average, each round trip was 40 miles and pharmacists drove 2 hours per day. By using telemedicine, the study team can minimize the number of face-to-face in-person visits and increase pharmacist efficiency by 25%. the study team aim to increase the scalability of our novel, evidence-based barbershop model by addressing this inefficiency with the pilot study. In the LA Barbershop trial, each participant averaged 7 in-person visits in 6 months. the study team found that the initial in-person visits between the pharmacist, barber, and patron were essential for establishing trust as well as obtaining baseline electrolyte and serum creatinine levels (with our validated point-of-care device, iSTAT). However, once rapport has been established and blood pressure control achieved, the study team postulate that the effect can be maintained remotely with telemedicine. Our data indicate that most patients' can achieve their blood pressure goal in 3 months or less. the study team propose replacing additional in-person visits with telemonitoring (via Skype or FaceTime) at this juncture, provided blood chemistries are stable. the study team plan to pilot this in 20 patients from 2 to 3 barbershops for 12 months.

NCT02723552
TEPHRA investigates the effect of exercise on blood pressure and other cardiovascular factors in young adults with different birth histories. TEPHRA will recruit 200 participants from 18-35 years old with elevated blood pressure (100 participants pre-term born and 100 full-term born). Half of the participants from each birth group will be randomised into a 16 week supervised aerobic exercise intervention trial and the other half will be controls. Participants will complete 3 main study visits: * Visit 1: Baseline visit conducted at beginning of study * Visit 2: 16 weeks into study (upon completion of structured exercise intervention for the exercise group) * Visit 3: End of study (52 weeks) Each visit will repeat the same set of cardiovascular measures including CPET, echo, blood pressure, vascular stiffness, and other measures. 50 participants from each group will complete an MRI sub-study of the heart, brain, and liver.
