Pulmonary hypertension (PH) is high blood pressure in the lungs. In PH, the right side of the heart must work so hard to push blood through the lungs that it can cause heart failure and death. There is no cure, but there's hope. The Pulmonary Hypertension Association is PHighting back.

What You Support

The Pulmonary Hypertension Association is the world's oldest and largest organization in the world that serves people living with pulmonary hypertension. PHA is a 501(c)(3) nonprofit that relies on the support of people like you to serve people with PH, families, caregivers, health care professionals and researchers.



Your support funds our advocacy efforts to raise awareness among the public, health care professionals, policy makers, influencers and elected officials about what kids and adults with PH face every day. We work with payers, policy makers, regulators and state and federal agencies on behalf of PH patients to reduce barriers to care and we partner with other organizations to achieve our goals.



We provide grants for innovative research at institutions nationwide. We support the next generation of physician-researchers and scientists focusing on adult and pediatric PH through fellowships, young investigators’ awards and early career grants. By collaborating with PH and associated disease communities, we advise and gather new knowledge and information to share with the PHA community.



We provide support and resources to help and empower adults and kids with PH and the many caregivers and families affected by this disease. We host in-person, telephone and online support to help people with PH at different stages of their journey. Through our international conference, regional meetings and online education, we offer networking and support and reliable information.



We promote quality patient care through clinically relevant educational content and CME/CE opportunities for health care professionals. Through the Pulmonary Hypertension Care Center (PHCC) accreditation program, we increase access to quality care by ensuring that a network of centers and programs are using the best consensus-based practices to diagnosis and treat people with PH.
