Active clinical trials for "Hypertension"

Mounting preclinical and clinical evidences have proved the causal role of gut microbiota on the pathogenesis of primary hypertension. Restoration of gut microbiota ameliorated high BP in rodents and/or human cases.A hypothesis is thus raised that gut microbiome restoration can be a potential approach to ameliorate hypertension. This study will perform intense fecal microbiota transplantation (FMT) intervention via oral capsules, in comparison with placebo capsules, to investigate the effect, safety and underlying mechanisms of gut microbiome intervention on primary hypertension.

The purpose of this study is to understand how the nervous system communicates to blood vessels to increase blood pressure during stress. The study will also investigate how hypertension and obesity influence the nervous system and vascular function. The study will involve measuring sympathetic nervous system activity and blood flow during common laboratory physiological stress protocols (e.g. hypoxia, exercise), and in response to infusion of drugs that cause vasodilation or vasoconstriction.

Uptake of a community-based evidence-supported interventions for hypertension control in Ghana are urgently needed to address the cardiovascular disease epidemic and resulting illness, deaths, and societal costs. This study will evaluate the effect of Practice Facilitation on the uptake and maintenance of the evidence-based task-shifting strategies for hypertension control (TASSH) protocol across 70 Community-based Health Planning and Services (CHPS) zones delivered by trained community health officers. Findings from this study will provide policy makers and other stakeholders the "how to do it" empirical literature on the uptake of evidence-based interventions in Ghana, which may be applicable to other low-income countries.

This study will be the first to distinguish the relative contributions of sleep, circadian and behavioral mechanisms to the non-dipping BP profile in Black adults and will lay the groundwork for optimizing therapies dependent on mechanisms, such as targeting sleep, targeting circadian rhythmicity, or targeting behaviors, and raising the possibility that ideal therapy for hypertension (HTN) may differ by race. This research will ultimately help to improve health and survival in black populations with HTN.

Cicletanine, which has been approved and launched for hypertension in France and Germany, has promise beyond hypertension in critically-unmet needs such as diabetes. It is evident from in vitro, animal and human studies that cicletanine's optimal dose in diabetes and other challenging, critically-unmet needs is likely to be higher than that for hypertension. Cicletanine's maximum tolerated dosage is not known, but the drug's dose-limiting effects are documented to be potassium loss and sodium loss from thiazide-type activity (one of the therapeutic mechanisms the drug is known to have); such thiazide-type losses are known to be reversed safely by magnesium. This trial explores the ability of magnesium to enhance cicletanine safety at higher doses in a trial involving patients with hypertension complicated by diabetes.

The VITamin D and OmegA-3 TriaL (VITAL; NCT 01169259) is an ongoing randomized clinical trial in 25,875 U.S. men and women investigating whether taking daily dietary supplements of vitamin D3 (2000 IU) or omega-3 fatty acids (Omacor® fish oil, 1 gram) reduces the risk of developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses. The VITAL Hypertension ancillary study is being conducted among participants in VITAL and will examine whether vitamin D or omega-3 fatty acids are related to changes in blood pressure and hypertension.

The purpose of this study is to investigate the influence of physical training on exercise capacity, quality of life, functional class, oxygen consumption and right ventricular function in patients with severe associated pulmonary arterial hypertension (APAH) as part of a congenital heart defect with / without Eisenmenger's Syndrome

It has been shown in a pilot randomised controlled study [SNAP-HT [4]; REC 14/SC/1316] that blood pressure self-management during the post-partum period after hypertensive pregnancies, results in lower blood pressure after six months; even when medication has been stopped. The team now want to assess whether this blood pressure reduction can be reproduced in a larger, randomised, study (data analysis blinded) and whether the blood pressure lowering has additional benefits in terms of other cardiovascular and cerebrovascular changes known to occur in women who have had a hypertensive pregnancy. The investigators therefore plan to run a trial of self-management in the post-partum period, using updated Blue-tooth® enabled blood pressure monitoring coupled to physician-assisted dose titration to further advance the self-management aspect of the intervention. The physicians will be specialist clinicians who form part of the research team. The investigators will measure additional structural and functional end organ differences, using magnetic resonance imaging of the brain and heart as well as echocardiography and retinal imaging. This will provide insight into the impact of post-partum blood pressure control on the maternal cardiovascular system and how this associates with blood pressure changes. Together, these studies will help refine future intervention strategies in this cohort of patients.

Post-marketing surveillance of Twotopsplus.

This study will test the preliminary efficacy of adding a very low carbohydrate dietary intervention to the evidence-based DPP-GLB on blood pressure reductions for lower-income AA men and women in a community-based clinic.
