Active clinical trials for "Hypertension"

Hypertension and dyslipidemia are very prevalent diseases in general population, and the prevalence is keep increasing especially on population with advanced age. Both diseases are major risk factor of cardiovascular disease, and many complication could be induced if not managed properly. Also, these diseases need consistent medication for long time, so the compliance to the treatment is an important issue for these diseases. Treatment effect of olmesartan to hypertension and rosuvastatin to dyslipidemia is already proven in previous studies, and these medication does not have interaction with each other. By using fixed-dose combination of these drugs, the investigators could improve the compliance to medication, and may have better treatment effect. In this single center, randomized, phase 4 clinical trial, the investigators divided patients into 2 groups, one with fixed-dose combination of 2 drugs, while another with 2 separated drugs. Each patient in this study was evaluated at first visit, and outcomes are evaluated at 26 weeks after the start point of medication. The primary outcome of this study was compliance of prescribe medication, and the secondary outcome was blood pressure (systolic, diastolic), cholesterol, and low density lipoprotein cholesterol.

Obesity is a major risk factor for premature arterial abnormalities including high blood pressure and increased stiffness. Previous studies have shown that weight loss via lifestyle modifications is associated with a decrease in large artery (aorta) stiffness. However, along with decreases in fat mass, hypocaloric diet reduces muscle mass. Low-intensity resistance exercise training (LIRET) results in similar increases in muscle mass and strength than those observed after high-intensity resistance exercise. The investigators hypothesis is that weight loss via diet combined with LIRET would additively reduce arterial stiffness and blood pressure (BP) in obese women. The investigators also hypothesize that the improved arterial function with weight loss would be associated with beneficial changes in the main mechanisms involved in BP regulation.

This is an intra-subject crossover comparative safety study to evaluate the effect of intravenous (IV) bolus injection of SonoVue on pulmonary hemodynamics.

The primary objective of the study is to assess the effect of financial incentives on the use of home health monitoring devices among high-risk patients. In addition, there are three secondary objectives: (1) obtain preliminary evidence regarding whether the monetary value of incentives has a differential effect on the use of home health monitoring devices; (2) identify potential barriers that prohibit regular use of home-based health devices using qualitative data; and (3) assess the usability of a newly developed web portal and its feasibility for future randomized clinical trials aimed at changing health-related behaviors.

High sodium intake causes hypertension. Various efforts for reducing salt consumption are proceeding all over the world. Solar salt contains reduced sodium and abundant mineral, such as calcium, potassium, and magnesium, comparing to ordinary salt. Use of solar salt, instead of ordinary salt, may have beneficial effects to blood pressure. The investigators are going to conduct a preliminary study that can support antihypertensive effect of solar salt intake.

The introduction of angiogenesis inhibitors has remarkably improved treatment of patients with several types of cancer. One of the most reported side effects of angiogenesis inhibitors is hypertension. In patients treated with bevacizumab, a monoclonal antibody against vascular endothelial growth factor, hypertension had an overall incidence up to 32%. The increase in blood pressure occurs early in treatment. The etiology of hypertension caused by treatment with angiogenesis inhibitors is unclear. Understanding the pathogenesis of this side effect is essential for optimal treatment with this class of drugs. The primary objective is to explore the effect of bevacizumab infusion on endothelium-dependent vasodilation of forearm resistance arteries.

Black men constitute the demographic group with the greatest burden of premature death and disability from hypertension (HTN) in the United States. But while the disproportionately high rate of hypertension-related morbidity and mortality is well documented, the epidemic of colorectal cancer (CRC) among black men is comparatively under-appreciated. For example, CRC is a leading cause of cancer death in black men with a death rate 50% higher than in white men. Low rates of screening for CRC in this population contribute significantly to this problem. The purpose of this randomized controlled trial (RCT) is to evaluate the effect of a lifestyle intervention delivered through telephone-based motivational interviewing (MINT) versus a patient navigation intervention on blood pressure reduction and CRC screening.

This is a multi-centered, randomized, parallel group, interventional & open label clinical trial accessing efficacy of intervention effect by smart care system over existing treatment group for lowering blood pressure of hypertension patients taking anti-hypertension drug.

The purpose of this study is to evaluate the effect of the antihypertensive drug, nebivolol (Bystolic), compared to metoprolol (Lopressor) and sildenafil (Viagra) on blood pressure in patients with autonomic failure and supine hypertension.

The objective of the project is a test-of-concept of an intervention to reduce the effects of the perception of discrimination on the care of patients with chronic illness. Perception of discrimination manifests itself as stereotype threat. We hypothesize that stereotype threat impairs communication between minority patients and their physicians because of increased stress and diminished trust, resulting in interactions that are less successful at enhancing patient self-efficacy, in turn resulting in lower rates of adherence with anti-hypertensive medication. The intervention is a self-affirmation exercise performed prior to a patient-physician visit. A similar intervention has been shown to reduce the racial gap in academic performance in middle school classrooms. We will explore the mechanistic effects of the intervention by analysis of audiotapes of patient-provider visits following the intervention. We will measure the effect of the intervention on minority hypertensive patients' adherence with antihypertensive medication and blood pressure. We will enroll 200 African American and Latino patients with hypertension and randomize 100 patients to perform the exercise and 100 patients to perform a null control exercise before the visit. We will assess change in patient's adherence with antihypertensive medications and in blood pressure over the six months following the index visit. In order to better understand the effects of the intervention we will measure subject's mood following the exercise, and self-reported stress levels, trust in the physician, and medication self-efficacy following the visit. We will also assess the quality of the patient-provider interaction from detailed analysis of audiotapes and from patient questionnaires. Following a subsequent patient-physician visit, we will conduct telephone interviews with patients to assess for persistence of any effects of the intervention.
