What is Pulmonary Hypertension?
Pulmonary Hypertension (PAH) begins when tiny arteries in your lungs become narrow or blocked. This causes increased resistance to the flow of blood in the lungs, which in turn raises pressure within the blood vessels or what could be termed "high blood pressure of the lungs." As a result, the right side of the heart, which pumps blood into the lungs, has to pump against a higher resistance to blood flow. This makes it more difficult to pump the blood through the lungs, eventually causing the heart muscle to weaken and sometimes fail completely.

We are not currently enrolling for pulmonary hypertension trials, but we are constantly reviewing new studies for future enrollment.
