Active clinical trials for "Hypertension"

This study is aimed to assess the efficacy of combined treatment with two antihypertensive agents (telmisartan and nifedipine) in subjects with mild hypertension exposed to high altitude.

Preeclampsia (PE) is a common disorder of pregnancy that complicates 4-7% of all pregnancies. It is a serious condition with acute proteinuria and hypertension and varying degrees of edema after 20 weeks of gestation. PE leads to a severe risk of low birth weight because of prematurity with inherent complications. The pathogenesis is unknown but is assumed to involve placental ischemia.The primary placental disorder results in renal glomerular injury. Established PE is associated with paradoxical suppression of the renin-angiotensin-aldosterone system, RAAS. Despite suppressed RAAS, patients with PE retain NaCl(sodium chloride) after an intravenous isotonic NaCl overload compared to healthy pregnant women on a low NaCl diet. The investigators believe to have data that provide a possible explanation for the overall relationship between proteinuria, NaCl retension, suppression of RAAS, hypertension and underdevelopment of placenta. Earlier data, which the investigators have confirmed, shows abnormal glomerular loss of the enzyme plasmin/plasminogen from plasma to the urine in PE. Active plasmin in urine from patients with nephrotic syndrome and PE activates the epithelial sodium channel ( ENaC ) in renal collecting duct cells. The investigators hypothesize that loss of plasmin/plasminogen are shared for the diseases with proteinuria, including PE, and that plasmin- driven ENaC (epithelial sodium channel) activation is a causal factor in the pathophysiology of established PE. Hyperactive ENaC causes primary renal sodium retention with secondary suppression of the renin-angiotensin-aldosterone system. Aldosterone is recently established as a placental growth factor. Plasma-aldosterone levels are significant higher in normal pregnant women. PE is characterized by low aldosterone levels (a discovery the investigators have also confirmed) and by placental underdevelopment. Study Aim: To test specific hypothesis regarding established PE´s pathophysiological mechanisms. Study Hypothesis: Excretion of urine proteases (plasmin/plasminogen) in PE leads to an activation of ENaC and hence RAAS is less NaCl sensitive while the blood pressure is more NaCl sensitive compared to healthy pregnant women. The degree of aldosterone suppression in PE determines placental development

This efficacy and safety study will evaluate LUMIGAN® RC/ LUMIGAN® .01 (bimatoprost 0.01%) alone compared to TRAVATAN Z® (travoprost 0.004%) and TIMOLOL MALEATE-EX, 0.5%/TIMOLOL GFS 0.5% (timolol 0.5% ophthalmic gel forming solution) in patients who require IOP lowering therapy.

To compare the efficacy and safety of two dose adjustment regimens (i.e. weight-based and non-weight-based) for the treatment of Chinese hypertensive emergency patients.

The purpose of this study is to evaluate the efficacy and safety of DWJ1276

This is a randomized study with two treatment arms: 'initial Selective Laser Trabeculoplasty (SLT) followed by conventional medical therapy as required' ('Laser-1st') and 'medical therapy without laser ('Medicine-1st'). It compares quality of life in the two arms at three years, while also examining the incremental cost and cost-effectiveness of Laser-1st versus Medicine-1st.

To analyze the efficacy of beraprost and sildenafil for treatment of pulmonary hypertension in children with left to right shunt. analyze the efficacy and side effects.

This study of MK-5475 in participants with Group 1 pulmonary arterial hypertension (PAH) will assess the safety, tolerability and pharmacokinetics (PK) of inhaled MK-5475. There is no formal hypothesis to be tested.

American College of Cardiology/American Heart Association (ACC/AHA) hypertension guidelines recommend lifestyle modification for patients with elevated blood pressure. While eating a Dietary Approaches to Stop Hypertension (DASH)-type diet, increasing physical activity, and weight loss have been shown to reduce blood pressure, limited resources are available in the primary care setting to help patients make these changes. In this study, the investigators will compare the efficacy of a self-guided vs. dietitian-led approach using web-based lifestyle modification tools to reduce weight, improve dietary quality, and lower blood pressure in overweight/obese adults with elevated blood pressure.

PRECIOUS Study aims to evaluate the efficacy and safety of therapy with fixed-dose combination (FDC) of perindopril/amlodipine (Amlessa®) and FDC of perindopril/indapamide/amlodipine (Co-Amlessa®) on blood pressure reduction in both previously untreated patients and patients with previous antihypertensive therapy. Adult patients with AH who are treatment-naïve with systolic blood pressure (SBP) from 150 mmHg or higher AND/OR diastolic blood pressure (DBP) from 95 mmHg or higher (SBP ≥ 150 mm AND/OR DBP ≥ 90 mmHg for patients with type 2 diabetes mellitus ) and uncontrolled patients on mono, dual or triple antihypertensive therapy with systolic blood pressure (SBP) from 140 mmHg or higher AND/OR diastolic blood pressure (DBP) from 90 mmHg or higher (SBP ≥ 140 AND/OR DBP ≥ 85 mmHg for patients with type 2 diabetes mellitus) will be invited to participate in this study. During 16-week trial, seven study visits are planned. At first study visit physical examination, medical history, BP measurement, electrocardiogram (ECG), laboratory analysis and of Ambulatory Blood Pressure Measurement (ABPM) will be performed. Based on their previous antihypertensive therapy, patients will receive to treatment with either Amlessa® or Co-Amlessa® for the duration of 16 weeks and blood pressure measurements, laboratory investigations and patient interviews will be performed at study follow-up visits to assess the treatment efficacy (proportion of patients reaching normal office blood pressure after 16 weeks of treatment) and safety.
