Active clinical trials for "Hypertension, Pulmonary"

This study is collecting post-marketing information on the safety and effectiveness of Ventavis under the routine clinical practice for patients with PAH

The study will recruit and follow up patients for six months patients newly diagnosed with pulmonary hypertension from twelve centers across four countries; South Africa, Mozambique, Cameroon, Nigeria. The main aim of the study is to describe the aetiology, natural history and management practices of pulmonary hypertension in Africa.

Clinical improvement has been demonstrated after cardiorespiratory rehabilitation in patients with pulmonary hypertension. Rehabilitation is therefore now part of the recommendations for good practice. However, no data is available to elucidate the mechanism of this improvement: an improvement in myocardial reserve or an improvement in peripheral muscular capacity? The main objective of this study is to evaluate the difference in right ventricular contractile reserve before and after cardiorespiratory rehabilitation during stress ultrasound in pulmonary hypertension in 10 patients with pulmonary hypertension.

The linear or nonlinear relationship of pulmonary systolic pressure and cardiovascular and kidney outcome after non-cardiac surgery is unknown. This study is to explore the relationship of the two and try to identify the possible threshold of pulmonary systolic pressure for major cardio-vascular events after non-cardiac surgery.

This study plans to learn more about activity levels in children with pulmonary hypertension. Pulmonary hypertension is a condition where the pressure in the lungs is higher than normal. This can affect the person's heart. The purpose of this study is to see if measuring activity in children with pulmonary hypertension and comparing it to activity in children without pulmonary hypertension can give their doctor helpful information on how they are feeling and how their treatment is working.

Neonatal pulmonary hypertension is a rare but serious condition resulting from a lack of adaptation to extra-uterine life in some newborns. In the short term, the risk of death requires rapid and appropriate management of this transient pathology. In the long term, these newborns present a greater brain vulnerability, a consequence of the pathology itself with cerebral hypoxia but also invasive and aggressive therapies. Although current scientific evidence indicates a correlation with the existence of neurological developmental disorders, the understanding of the long-term neurological outcome of these babies remains poorly documented.

Pulmonary hypertension (PH) is a condition in which high blood pressure develops in the lungs and right side of the heart. People with PH suffer from shortness of breath, chest pain, heart failure, heart rhythm problems, and fainting. PH is diagnosed using a test called a cardiac catheterization where blood pressure is measured directly using a tube placed in the right side of the heart and lung arteries. Because a cardiac catheterization is invasive, researchers are investigating ways to diagnose PH using imaging tests that are not invasive. The study will evaluate whether or not a magnetic resonance image (MRI) of the heart, and blood tests can detect PH.

The study seeks to analyze the patient reported effects of pulmonary hypertension medications and compare these with the side effects described on the package inserts. Side effects for these PH medications have been described in the adult population, but have never been described in the pediatric population. This information can better improve patient care and be used to characterize the side effects resultant from these medications.

Pulmonary hypertension is a progressive and life threatening condition. It is characterized by severe remodeling of the pulmonary vessel wall, obstructive plexiform lesions, multi-focal thrombosis, and enhanced vasoconstriction. All of these characteristics contribute to increased pulmonary vascular resistance. Circulating endothelial microparticles (EMPs) play an integral role in the pathogenesis and perpetuation of pulmonary hypertension. Levels of EMPs are considered a reliable biological parameter of endothelial injury. We propose to assess the evolution of both circulating and pulmonary venous EMPs in patients with PH. Assessments will be made before and after initiation of Endothelin-1 (ET-1) Receptor blocker therapy, and correlated to their patterns with the changes in mean PAP, the 6 Minutes Walking Distance test, and circulating Endothelin-1 values. Measurements of the endothelial microparticle circulating levels (assessed by flow cytometry methods) will be made before, 1 month and 3 months after initiation of therapy.

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.)
