United States Pulmonary Hypertension Scientific Registry: Baseline Characteristics.

Background: The treatment, genotyping, and phenotyping of patients with World Health Organization Group 1 pulmonary arterial hypertension (PAH) have evolved dramatically in the last decade.

Research Question: The United States Pulmonary Hypertension Scientific Registry was established as the first US PAH patient registry to investigate genetic information, reproductive histories, and environmental exposure data in a contemporary patient population.

Study Design And Methods: Investigators at 15 US centers enrolled consecutively screened adults diagnosed with Group 1 PAH who had enrolled in the National Biological Sample and Data Repository for PAH (PAH Biobank) within 5 years of a cardiac catheterization demonstrating qualifying hemodynamic criteria.

United States Pulmonary Hypertension Scientific Registry (USPHSR): rationale, design, and clinical implications.

Diagnostic World Health Organization (WHO) Group 1 pulmonary arterial hypertension (PAH) and Diagnostic Group 1' pulmonary veno-occlusive disease (PVOD) and/or pulmonary capillary hemangiomatosis (PCH) are progressive and fatal disorders. Past registries provided important insights into these disorders, but did not include hormonal exposures or genomic data. The United States Pulmonary Hypertension Scientific Registry (USPHSR) will provide demographic, physiologic, anorexigen and hormone exposure, genomic, and survival data in the current therapeutic era for 499 patients diagnosed with PAH, PVOD, or PCH.

Delay in recognition of pulmonary arterial hypertension: factors identified from the REVEAL Registry.

Background: Pulmonary arterial hypertension (PAH) is a progressive and fatal disorder. Despite the emergence of effective therapy, PAH is commonly at an advanced stage when recognized. Factors associated with a prolonged symptomatic period before the recognition of PAH have not been fully evaluated.

The changing picture of patients with pulmonary arterial hypertension in the United States: how REVEAL differs from historic and non-US Contemporary Registries.

Background: REVEAL (The Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management) provides current demographics of patients with group 1 pulmonary arterial hypertension (PAH) in the United States.

Methods: A total of 2,967 patients with PAH diagnosed based on right-sided heart catheterization were enrolled in REVEAL between March 2006 and September 2007. Demographics from the REVEAL patient cohort and REVEAL subpopulations (matched by inclusion criteria to other registries) were compared with historic US registry data and other contemporary US and non-US national PAH registries by inclusion criteria, including the National Institutes of Health (NIH) PAH registry and the French PAH registry.

Pulmonary arterial hypertension: baseline characteristics from the REVEAL Registry.

Background: The Registry to EValuate Early And Long-term pulmonary arterial hypertension disease management (REVEAL Registry) was established to provide updated characteristics of patients with pulmonary arterial hypertension (PAH) and to improve diagnosis, treatment, and management.

Methods: Fifty-four US centers enrolled consecutively screened patients with World Health Organization group I PAH who met expanded hemodynamic criteria of mean pulmonary arterial pressure (PAP) > 25 mm Hg at rest (30 mm Hg with exercise), pulmonary capillary wedge pressure (PCWP) or= 240 dynes x s x cm(-5).
