Pulmonary Arterial Hypertension in the Southern Hemisphere Results From a Registry of Incident Brazilian Cases

摘要

BACKGROUND: Pulmonary arterial hypertension (PAH) is a rare and ultimately fatal disorder of the pulmonary vasculature. There is increasing interest in the worldwide characteristics of patients with PAH, although data coming from the Southern Hemisphere remain scarce. The objective of this study was to describe a cohort of incident patients with PAH from a large reference center in Brazil.
