How Patient Data Supports PVDOMICS

The PVDOMICS study (Redefining Pulmonary Hypertension through Pulmonary Vascular Disease Phenomics) is a partnership between PHA and the National Heart, Lung and Blood Institute at the National Institutes of Health. PVDOMICS uses clinical and biological “omics” data from all PH (Groups 1 through 5) classifications. Learn more about PVDOMICS and participating PH clinical centers.

PHA Conference Research Room

Each biennial meeting of the PHA International PH Conference and Scientific Sessions provides an opportunity for PH patients to participate in research studies. The PHA Conference Research Room enables patients to answer questions or provide biological data (i.e. cheek swabs and blood samples). At the 2018 Conference in Orlando, Florida, more than 200 Conference attendees participated in Research Room studies. Learn more about the PHA Conference Research Room.
