Active clinical trials for "Hypertension"

This study is designed to explore the feasibility of providing 24-hour ambulatory blood pressure monitoring in community pharmacies. The investigators hypothesize it will be feasible for community pharmacies to provide the service to assist medical providers in the diagnosing and management of high blood pressure. The investigators will also survey participants regarding their experience with the service as well as conduct interviews with participating pharmacists and medical providers to understand their views and opinions on the feasibility of the service.

The purpose of this study was to examine the impacts of a 12-week resistance band exercise program on body composition, aging-related hormones, and blood pressure in postmenopausal women with stage 1 hypertension. Twenty postmenopausal women with hypertension participated in this study. Participants were randomly allocated into the resistance band training group (EX, n = 10) or the control group (CON, n = 10). The EX group performed a resistance band exercise training program at jump rope training program at 40-70% of their heart rate reserve (HRR) 5 days/week for 12 weeks (sessions 60 minutes in duration). The CON group did not participate in any exercise, dietary, or behavioral intervention. Body composition, aging-related hormones (growth hormone, insulin-like growth factor 1, dehydroepiandrosterone, and estradiol), and blood pressure were measured before and after the 12-weeks study.

Assessment of the possible difference in masked hypertension prevalence when it is evaluated by automated office blood pressure measurement (AOBPM) instead of office blood pressure measurement (OBPM) in patients with obstructive sleep apnoea.

The purpose of the present clinical trial is to study the effect of somatostatin in the regulation of velocity and blood flow of the hepatic circulation in patients undergoing liver resection. The patients will be randomized in two groups: the study group will receive somatostatin and the control group will receive the placebo. In both groups, patients will undergo hepatectomy and directly postoperatively they will receive either somatostatin or placebo, depending on their randomization. The primary endpoint will be the increase or decrease of the velocity and the flow of the hepatic circulation estimated by ultrasonography compared to the same parameters when measured preoperatively.

The development of portal hypertension is a vital event in the natural progression of cirrhosis and is associated with severe complications including gastroesophageal varices bleeding. Cirrhotic patients with hemorrhagic shock and/or liver failure caused by variceal bleeding face a mortality of 5-20%. Hepatic venous pressure gradient (HVPG) is the recommended golden standard for portal pressure assessment globally with favorable consistency and repeatability. Reducing the HVPG to levels of 12mmHg or below is associated with protection of variceal hemorrhage. An HVPG> 16mmHg indicates a higher risk of death and HVPG ≥ 20mmHg predicts failure to control bleeding, early rebleeding, and death during acute variceal hemorrhage. The management of portal hypertension has showed a trend of diversification with the development of medication, endoscopy, radiological intervention and liver transplantation. Although medication and endoscopic therapy have achieved preferable effects and are recommended as standard of care for the prevention of variceal rebleeding, patients with HVPG≥ 16mmHg still have a high risk of treatment failure and a high rate of rebleeding. Recent years, early TIPS is recommended as the first-line therapy for the prevention of rebleeding in cirrhotic patients with HVPG≥ 20mmHg. However, for those with HVPG values between 16 to 20mmHg, there is still lack of strong evidence to demonstrate the best practice for the management. With the rapid advancement of laparoscopic device and technique, the utility of laparoscopic splenectomy and pericardial devascularization showed less surgical trauma, bleeding and complications while retaining dependable effects compared to traditional open surgery, especially for portal hypertension with hypersplenism. In the study, the investigators aim to conduct a multicenter randomized controlled trial to compare the safety and effectiveness of HVPG-guided (16 to 20mmHg) laparoscopic versus endoscopic therapy for variceal rebleeding in patients with portal hypertension.

Pulmonary arterial hypertension (PAH) is progressive life limiting disease with a median survival of less than 3 years without treatment. Current drug trials in PAH commonly use simple tests for example the 6-minute walk test, blood tests such as N-terminal pro-brain-type natriuretic peptide (NT-pro-BNP) and BNP, and haemodynamic measures such as PAP and PVR obtained by RHC as endpoints. These tests are surrogate markers of disease severity in patients with pulmonary hypertension. There is now evidence suggesting that magnetic resonance imaging (MRI) may be helpful in the follow up of patients with PAH with high accuracy for the detection of treatment failure, this is because MRI can track changes occurring in the heart by direct visualisation of cardiopulmonary morphology and function, an advantage over existing methods. However, the reproducible of MRI measurements in patients with PAH is not known, and the comparative repeatability of MRI in relation to traditional candidate endpoints such as walk tests and blood tests used in drug trials is not known.

The recent hypertension clinical practice guidelines published by American College of Cardiology (ACC) and American Heart Association (AHA) reduced the target BP to 130/80 mmHg, indicating the needs for more aggressive efforts in hypertension treatment. However, studies in Koreans must be preceded before applying such new overseas guidelines; thus, this study has been designed to establish clinical materials reflecting treatment setting in Korea. In this study, patients with uncontrolled hypertension whose antihypertensive regimens are changed to ARB-based therapy (ARB monotherapy or ARB-containing combination therapy) will be followed to assess the treatment trend, treatment effect, and risk of cardiovascular disease.

Patients with interstitial lung disease (ILD) and scleroderma who develop pulmonary hypertension (PH) do not fit well into the current classification system and treatments for pulmonary hypertension. This study aims to better understand patients with ILD-PH and scleroderma and to determine if treatment with Macitentan is beneficial.

The use of TRIple fixed-dose COmbination in the treatment of arteriaL hypertension: opportunity for effective BP control with cOmbined antihypertensive therapy. The main aim of this study to assess the antihypertensive effectiveness effect on the 24-hour BP profile, as well as tolerability of and compliance to the treatment with a triple FDC of amlodipine / indapamide / perindopril arginine in hypertensive patients in the real clinical practice. Type of program: Multicenter, observational, non-controlled, open-label program. Investigators: Cardiologists and outpatient (primary care) physicians (general practitioners). Number of patients: 1,300 hypertensive patients.

This study will test the feasibility of a home blood pressure telemonitoring (HBPTM) system in patients with minor stroke or TIA in the past year. The telemonitoring system will consist of a blood pressure machine and an online survey to submit blood pressure measurements. The investigators want to test whether patients can persistently use the telemonitoring system with ease and whether telephone instructions for blood pressure medications from the research nurse can be correctly understood. A secondary purpose of this study is to look at the effects of telemonitoring in blood pressure and stroke recurrence.
