“PHA’s research program has yielded an explosion of understanding about PH that was not known before.” John Newman, MD, Vanderbilt University Medical Center

Thirty years ago, there were no pulmonary hypertension treatments available. Through focused research there are now 14 PH-specific treatments with more in development. But we know that your ultimate wish is for a cure, and that is why PHA will continue to support the work of researchers to extend and improve the lives of those with PH.

PHA’s Research Program

PHA’s Research Program has committed more than $8 million for PH research through the generous donations and fundraising events of the PH community, and by leveraging partnerships with the National Heart, Lung, and Blood Institute (NHLBI) and the American Thoracic Society (ATS). We have supported 70 promising researchers through five independently reviewed, cutting-edge research programs.

The Redefining Pulmonary Hypertension through Pulmonary Vascular Disease Phenomics (PVDOMICS) program is a network of seven clinical sites and a data coordinating center—funded by the National Heart, Lung, and Blood Institute of the National Institutes of Health with additional support from the Pulmonary Hypertension Association—that will perform comprehensive, deep phenotyping across all types of pulmonary hypertension (PH).
