United States Pulmonary Hypertension Scientific Registry (USPHSR)


About this study

The purpose of the United States Pulmonary Hypertension Scientific Registry (USPHSR) will be to promote a greater understanding of PAH in an era of genetic discoveries, the study of the physical make up of individual people, and new treatments through education and collaborative assessment of information among pulmonary hypertension (PH) centers throughout the U.S. The development of a national USPHSR Registry will be an important element for advancement of the understanding of PAH and improvement of the care of patients who suffer from this life threatening disorder.

Participation eligibility
