Welcome! KnowYourPH.org is a dedicated source of vital information for
patients with pulmonary hypertension (PH), as well as for families and
friends of those who are facing PH. The goal of this site is to give
you accessible, relevant information that will help you understand the
diagnosis, evaluation, and treatment of PH. We know that PH can be a
complex and at times frightening condition, so we’ve organized the site
around patients’ most frequently asked questions. To guide you in
better visualizing the underlying mechanisms (pathophysiology) of
related medical problems and symptoms, we offer a series of
interactive, animated diagrams. We hope you will find KnowYourPH.org to
be useful, and we welcome your feedback.
