Active clinical trials for "Familial Primary Pulmonary Hypertension"

In this prospective study, the investigators will implement a systematic screening program and 3-year follow-up in a cohort of asymptomatic BMPR2 mutation carriers. This study is designed to: determine predictive factors (biological, functional, radiological and hemodynamic) of development of PAH monitor these subjects' clinical, functional, biological, echocardiographic and hemodynamic characteristics assess the risk of occurrence of PAH screen patients with PAH at an early stage of disease and offer them an early management constitute a collection of biological samples (0, 12, 24 months follow-up) of asymptomatic BMPR2 mutation carriers.

This prospective, non-interventional, multi-center study documents observational data on subjects under routine treatment of Pulmonary Arterial Hypertension, functional class III with inhaled Iloprost administered with I-Neb AAD (Adaptive Aerosol Delivery) device. The observation period for each subject covers a one year treatment period with inhaled Ventavis. For each subject, the investigator or a delegate collects data as defined in the case report form at an initial visit, routine follow-up visit at 6 months and final visit at 12 months.

The purpose of this study is to use non-invasive imaging to determine the metabolic phenotype of the right ventricle in patients with pulmonary arterial hypertension across a spectrum of disease severity.

To identify epigenetic-sensitive modifications and novel biomarkers linked to pathogenesis of pulmonary arterial hypertension (PAH), we will perform the first study analyzing differentially-methylated regions (DMRs) in circulating T cells (CD04+ and CD08+) isolated from peripheral blood of patients undergoing right heart catheterization. Moreover, we will perform RNA deep sequencing on lung tissue biopsies to validate if DNA methylation signatures in circulating T cells could reflect perturbations of gene expression in lung tissues.

Patients with scleroderma can develop heart failure due to high blood pressure in the lungs (a condition called pulmonary arterial hypertension). It is important to find pulmonary arterial hypertension early, so that it can be treated before heart failure develops. However, the tests that we now use to find the earliest form of this disease in scleroderma patients are not good enough. This study will examine whether tests performed during exercise can improve our ability to find early pulmonary arterial hypertension. The study will also try to identify genes that are responsible for the development of pulmonary arterial hypertension.

It is not always known what causes PAH or what the best treatment is. The doctors doing this study would like to understand more about why some people develop PAH and other do not. They also would like to learn more about which treatments might help PAH and which people might respond better to treatments. Doctors think that testing certain substances found in blood cells might help answer these questions. These substances are normally released by our bodies to protect us from infection and to tell the difference between normal and foreign substances in our body. Finally, a new test will study very small molecules called microRNA that control how our genes are expressed. This study is being done to see if blood samples can be tested to determine who might develop PAH, how well drugs will work to treat PAH and to learn more about the development of PAH.

This is an observational, multicenter, single-day, Phase 2 study. This study will include a 14-day Screening Period and Study Day 1 clinic visit. Participants will be required to perform an activity to induce symptoms of PAH, and participants' severity of self-reported symptoms of PAH will be measured from pre-activity, immediately after the activity, and through the 30-minute recovery. Participants will be asked about their PAH symptoms using 3 PGI-S questions that address their overall PAH symptoms, shortness of breath, and physical fatigue.

In this study researchers want to learn more about Pulmonary Arterial Hypertension, a type of high blood pressure in the lungs related to the narrowing of the small blood vessels in the lungs (group 1 according to WHO classification). Goal of the study is to describe the signs and risk factors of the illness at study start and the chances of survival.

Aim of the study is to compare novel parameters of right ventricle (RV) function from right heart catheterization (RHC) and magnetic resonance imaging (MRI) with PET-derived RV FDG uptake.

Assessment of the prognostic value of the estimation of plasma volume or its variation in patients with pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH) after acute right heart failure.
