Active clinical trials for "Hypertension, Pulmonary"

The purpose of the study is is to determine the effect, on the lung circulation, of BQ-123, an investigational compound which is not approved by the FDA.

Heart failure is a major medical and socioeconomic problem in western industrial countries, especially with aging populations. Heart failure with normal left ventricle systolic function (heart failure with preserved ejection fraction, HFPEF, heart failure with normal ejection fraction, HFNEF) are common causes of hospitalization mainly in the elderly population and are frequently associated with pulmonary hypertension. It is commonly seen, that patients with left heart disease and pulmonary hypertension with right ventricle dysfunction have a worse prognosis. The investigators hypothesize, that an additional treatment with Bosentan in this patients will improve their exercise capacity, symptoms, hemodynamics and quality of life.

The aim of the study is to assess the efficacy and safety of different doses of BAY63-2521 given orally for 12 weeks, in patients with symptomatic Pulmonary Arterial Hypertension (PAH).

This study is an international, multi-center, randomized, double-blind, placebo-controlled study in subjects with PAH who are currently receiving approved therapy for their PAH (i.e., endothelin receptor antagonist and/or phosphodiesterase-5 inhibitor). Study visits will occur at 4 week intervals for 16 weeks with the key measure of efficacy being the 6-minute walk test. Study procedures include routine blood tests, medical history, physical exams, disease evaluation, and exercise tests. Patients who complete all assessments for 16-weeks will also be eligible to enter an open-label, extension phase study (FREEDOM - EXT).

The purpose of this study is to evaluate the efficacy and safety of vardenafil in the treatment of pulmonary arterial hypertension.

This study is to demonstrate the safety, tolerability, pharmakokinetic and pharmacodynamic effect of BAY63-2521 in patients with pulmonary hypertension and stable treatment of sildenafil 20 mg.

Study to determine the long term safety of tadalafil in patients with increased blood pressure in the blood vessel that carries blood from the right heart to the lungs and to see if it will keep the disease from getting worse.

The primary objective is to determine the effect of ambrisentan on exercise capacity in subjects with PAH.

Determination of the effects of sildenafil citrate and epoprostenol when used in combination in patients with pulmonary arterial hypertension

To determine whether peripheral low dose systemic thrombolysis (PLST) is non-inferior to catheter directed acoustic pulse thrombolysis (ACDT) in improving RV function and reducing pulmonary artery pressures in submassive pulmonary embolism (PE)
