Active clinical trials for "Hypertension"

Hypertension is a progressive cardiovascular syndrome caused by multiple causes, which can lead to changes in the function and structure of the heart and blood vessels. It is the leading risk factor of cardiovascular disease. Berberine (BBR) hydrochloride is an isoquinoline alkaloid (chemical formula: C20H18NO4) extracted from traditional Chinese herb Coptis chinensis. It has been widely used to treat diarrhea and enteritis for hundreds of years in China. BBR has extremely high clinical application value. It is an over-the-counter drug with low price, good safety and few adverse reactions in China. We found that Berberine (BBR) hydrochloride tablets have a hypotensive effect in clinical practice. However, there are few clinical studies on the treatment of hypertensive patients with BBR tablets. In addition, the clinical dosage of BBR tablets is not uniform, and its molecular mechanism is still unclear. In order to further evaluate the clinical efficacy of BBR in reducing blood pressure and improving vascular endothelial injury, we carried out this clinical trial of drug intervention for hypertensive population. After signed the informed consent, the subjects are assigned to the lifestyle intervention group (CON) and berberine hydrochloride group (BBR). The berberine hydrochloride group (BBR) take berberine hydrochloride tablets (0.4g, 3 times/day, 3 months) . We will follow up blood pressure and vascular endothelial function in 1 month and 3 months after taking the medicine.

This study aims to evaluate the efficiency of EUS-guided combination therapy (EUS-guided PSE + EUS-guided treatment of varices) to EUS-guided treatment of varices alone in cirrhotic patients with portal hypertension who have developed gastroesophageal variceal hemorrhage and accompanied with hypersplenism.

This is a randomized controlled clinical trial with three parallel arms. This trial aims to evaluate the effectiveness of electroacupuncture on P6 acupoint for patients with hypertension,with respect to decreasing their blood pressure, safety of acupuncture ,and improving their quality of life as well.

This randomized controlled trial aimed to determine the subacute blood pressure effects of pharmacologically-treated elderly hypertensive patients after a single session of water aerobic exercise.

Studies have demonstrated that the early initiation of ACEI/ARB to patients with acute myocardial infarction is beneficial, especially in patients combined with reduced LVEF or mild-moderate heart failure. Therefore, ACEI/ARB is a traditional treatment for patients post-infarction. Recent clinical trials have demonstrated that Sacubitril/Valsartan is more beneficial than Ramipril to patients post-PCI.Besides, Sacubitril/Valsartan is also effective for essential hypertension.This study aims to assess the effect of Sacubitril/Valsartan on short-term prognosis in hypertensive patients with acute myocardial infarction compared against Valsartan.

Evaluation of the Efficacy and Safety of S-amlodipine+Chlorthalidone Combination Therapy and S-amlodipine+Telmisartan Combination Therapy in Hypertensive Patients Inadequately Controlled With CCB(Calcium Channel Blocker) Monotherapy

This is a retrospective chart review of women who labored and delivered in a single health care center. From that large group the investigators will evaluate women who were re-admitted in the post partum period for a hypertensive disorder. The study will also look at "Controls," a group of women with similar risk factors but did not require readmission.

Cardiovascular disease (CVD) is considered the main cause of mortality in the western world. There are many factors that contribute to the onset and progression of cardiovascular disease, including hypertension. Hypertension is a multi-factorial condition that includes nutritional disorders in its causality line. It is believed that advanced glycation end-products (AGEs) is one of the pathophysiological causes that explain the occurrence of high blood pressure in diabetic patients. This study has the role of describing the protocol of a randomized clinical trial aiming to evaluate changes in serum levels of end products of advanced glycation after an intervention for eating habit changes in hypertensive individuals. The investigators designed a randomized clinical trial, with non-blinded assessment of outcomes. Participants will be recruited from the outpatient clinic for hypertension of a public hospital in Porto Alegre, aged from 40 to 80 years old and without diabetes. Hypertension is defined as systolic blood pressure ≥ 140 mmHg, diastolic blood pressure ≥ 90 mmHg, or antihypertensive medication use. Participants will be assigned to one of two groups. The intervention group will receive monthly educational intervention sessions for low salt diet, high in fruits and vegetables, and low in processed foods for a period of 6 months. Besides these, the intervention group will receive a standard telephone interview every two weeks to motivate them to follow the diet. The control group will receive the usual counseling for low sodium diet in monthly appointment with a dietitian, following the hypertension care clinic protocol. This study aims to investigate if there are significant changes in serum levels of advanced glycation end products, after the nutritional intervention with diet guidance in fruits, vegetables, low in sodium and processed foods in hypertensive patients because several studies have shown that less processed food rich in antioxidants with low sodium content, play an important role in reducing levels of AGEs which are precursors of vascular inflammation and progression of cardiovascular diseases.

The purpose of this study is to evaluate the efficacy and safety of mirabegron (a B3 adrenergic receptor agonist) in patients with pulmonary hypertension secondary to heart failure by conducting a randomized multicenter phase II placebo-controlled clinical trial.

This is a randomized clinical trial with blinded, multi-center, involving the Federal University of in Rio de Janeiro(UFRJ), through the School of Nursing Anna Nery, as a proponent and research coordinator; and as a collaborative educational institutions, the Federal University of in Espirito Santo, represented by the Department of Nursing; and the Higher School of Sciences of the Santa Casa de Misericordia of Vitoria, developed by building doctorate thesis as a final product of the research.
