Active clinical trials for "Hypertension"

The purpose of this study is to determine the timeline of progression from pre-pulmonary hypertension to diagnosable pulmonary hypertension based on right heart catheterization. Moreover, to determine the timeline for progression from diagnosable pulmonary hypertension to clinical worsening of disease as defined as death, hospitalization, or worsening of PHT symptoms.

An observational study to investigate the efficacy, safety, tolerability and the effect on quality of life of Telmisartan (Micardis) and Telmisartan with HCTZ (Micardis Plus) in patients with hypertension

The purpose of this study is to investigate the epidemiology of resistant hypertension, evaluate the efficacy and feasibility of a standardized drug treatment regimen (including the randomization of two doses of the diuretic used - chlorthalidone), study two interventions in the group of patients that is non-compliant, and study environmental and genetic variables of individuals with resistant hypertension in a family design.

The purpose of this study is to determine whether a noninvasive method of measuring certain aspects of blood circulation (e.g., blood pressure, cardiac output) is an accurate and reliable method to detect changes in pregnant patients. Specifically,the investigators are interested in patients diagnosed with high blood pressure during their pregnancy, as compared with normal pregnant patients. A noninvasive, accurate method of taking these measurements in pregnant patients is not currently available.

The home monitoring of automated measuring devices may improve the management of the chronic diseases, and may decrease the incidence of fatal disease. The investigators conducted a small sample and short observation time research to explore the feasibility to carry out later large-scale research.

The objective of this post-marketing surveillance study is to evaluate the incidence of adverse events in Japanese subjects with pulmonary arterial hypertension treated with ambrisentan basd on prescribing information under the conditions of general clinical practice and also to grasp the following items; Unknown adverse drug reactions (ADRs) Incidence of ADRs to medical products in actual clinical practice Factors influencing safety of ambrisentan Factors influencing efficacy of ambrisentan Prognosis of subjects as well as efficacy and safety of ambrisentan in long-term use (VOLIBRIS® is a trademark of Gilead Sciences, Inc,. that GSK uses under license.)

This is an observational study to monitor the continued effectiveness of Ventavis (inhaled iloprost) in the long-term. The study observes the effects and the safety of Ventavis inhalation therapy over at least 2 years and up to 4 years. A total of 54 patients from around 30 study sites in Europe will be included in the study. This observational study will collect information in patients receiving a medication that is already available on prescription in the participating countries. Ventavis is used to treat moderate cases of primary pulmonary hypertension.

Clinical trial of implementation of clinical practice guidelines for managing hypertension in primary care clinics.

To investigate the genetic determinants of hypertension in three populations of the African diaspora, with a major focus on clarifying the role of genes that code for the renin-angiotensin system (RAS).

To test the hypotheses that hypertensive emergency was associated with non-compliance with antihypertensive medication, low level of contact with the medical care system, and alcohol abuse and cigarette smoking. Also, to describe the clinical characteristics of patients hospitalized with hypertensive emergency including morbidity, mortality, and cost, and the extent to which hypertensive emergency occured among previously diagnosed and treated hypertensives.
