Welcome to the National Biological Sample and Data Repository for Pulmonary Arterial Hypertension (PAH). Also known as the "PAH Biobank", we are a National Institutes of Health/National Heart, Lung & Blood Institute funded resource of biological samples, genetic data, and clinical data for the PAH research community. Our goal is to further PAH research by providing the largest cohort of WHO Group 1 PAH biological specimens and data for researchers to use in their studies.

We intend for our "power through numbers" to provide a robust study population for researchers to use in making new breakthroughs on the mechanisms and treatment of PAH. Whether you are interested in PAH, an enrolling center, a researcher or interested in enrolling you’ll find a collection of information on these pages that will help you learn more about the PAH Biobank.
