REVEAL Registry™: Registry to Evaluate Early And Long-term PAH Disease Management

Pulmonary Hypertension

The REVEAL Registry™ is a multicenter, observational, U.S.-based study of the clinical course and disease management of pulmonary arterial hypertension (PAH) patients. All consecutive consenting patients diagnosed with WHO Group I PAH according to specific hemodynamic criteria at participating institutions will be enrolled. Participating patients will be followed for a minimum of five years from the time of enrollment.

Evaluation of Patients With Known or Suspected Heart Disease

Peripheral Artery DiseaseCoronary Disease5 more

In this study researchers will admit and evaluate patients with known or suspected heart disease referred to the Cardiology Branch of the National Heart, Lung, and Blood Institute (NHLBI). Patients participating in this study will undergo a general medical evaluation, including blood tests, urine, examination, chest x-ray and electrocardiogram (EKG). In addition, patients may be asked to have an echocardiogram (ultrasound scan of the heart) and to perform an exercise stress test. These tests are designed to assess the types and causes of patient's heart diseases and to determine if they can participate in other, specific research studies.

A Study to Understand the Treatment Patterns in Patients With Pulmonary Arterial Hypertension or...

HypertensionPulmonary

The aim of this study is to understand the treatment patterns in patients with Pulmonary Arterial Hypertension (PAH) or Chronic Thromboembolic Pulmonary Hypertension (CTEPH) during a switch of treatment to Adempas in real-life clinical practice. In addition, this study will describe patient demographics and reason for switching

U.S. CTEPH Registry

Chronic Thromboembolic Pulmonary Hypertension (CTEPH)Pulmonary Hypertension

The U.S. CTEPH Registry is a multicenter, observational, U.S.-based study of the clinical course and treatment of patients diagnosed with chronic thromboembolic pulmonary hypertension (CTEPH), WHO Group IV Classification for Pulmonary Hypertension. The mission of the Registry will be to promote a greater understanding of the prevalence, pathophysiology, evaluation, and treatment of patients with CTEPH through shared information, education, and collaborative investigation among pulmonary hypertension (PH) centers of excellence throughout the U.S.

Screening for Pulmonary Vascular Changes in Patients With Chronic Myeloproliferative Diseases

Myeloproliferative DisordersPulmonary Hypertension

Goal of the study is to assess the frequency of pulmonary hypertension in patients with chronic myeloproliferative diseases. In each patient an echocardiography at rest will be performed. In patients without musculoskeletal disease an exercise test (spiroergometry) will be performed. Patients with elevated SPAP at rest or with reduced exercise capacity (peak VO2 < 65%) a right heart catheterization (RHC) will be recommended. Also patients with advanced NYHA functional class (III or IV) or with typical PH findings in electrocardiogram will be advised to undergo a RHC. Additionally for the evaluation of exercise capacity a 6 MWD will be performed. This work- up of patients allows clinical and hemodynamic evaluation.

Neolifes Heart - Pulmonary Hypertension in Preterm Children

Pulmonary HypertensionBronchopulmonary Dysplasia

NeoLifeS is a cohort follow up study that prospectively collects data of regular care of children born preterm in the University Medical Center Groningen (UMCG) and aims to improve the quality of care for these children. NeoLifeS-Heart is a sub-study that focuses on the problem that a high proportion of preterm infants develop cardiovascular disorders. Related to the immaturity of their lungs, preterm infants are at risk to develop the condition Bronchopulmonary dysplasia (BPD). Also, the vasculature of the lungs is often not fully developed, making them more vulnerable for the development of Pulmonary Hypertension (PH), a high blood pressure in the lungs. 15-20% of the infants with extremely low birth weight are believed to develop PH, this proportion has been suggested to raise to 50% in infants with severe BPD. The presence of PH significantly worsens the prognosis and survival of these children. The condition PH is insufficiently characterized. Knowledge of incidence, prevalence, risk factors for the development of PH and survival, will be the first step in improving detection strategies, possible treatment options and thereby prognosis and survival of these children. Objective: To determine the incidence and prevalence of PH in preterm infants. In addition we aim to identify risk factors for the development of PH and determine the survival and prognosis of these preterm infants. Study design: A prospective cohort study. Study population: All preterm infants, admitted at the neonatology UMCG, born <30 weeks and/or birth weight < 1000 gram, who participate in NeoLifeS Primary parameters: The occurrence of PH (Incidence and Prevalence). Secondary parameters: Maternal and neonatal patient characteristics that are potential risk factors for the development of PH, Morbidity-score (quality of life and hospital admissions) and mortality.

Reversal of Right Ventricular Steatosis in Pulmonary Hypertension

Pulmonary; HypertensionSteatosis1 more

The goal of this study is to elucidate the relationship between myocardial right ventricular triglyceride content (steatosis) and right ventricular dysfunction in participants with pulmonary hypertension, and investigate reversibility of this phenotype with omega-3 fatty acid treatment.

Evaluation of Novel Lung Function Parameters in Patients With Pulmonary Hypertension (PH)

Pulmonary Hypertension

Little is known about affection of small airways in patients with pulmonary hypertension as well as the ideal diagnostic approach. The investigators therefore aimed to evaluate novel or not widely used lung function tests for the evaluation of airway function in patients with PH.
