A member asked:

Is there a difference between pulmonary artery disease and pulmonary artery hypertension?

A doctor has provided 1 answer

Terminology: pulmonary artery disease is a vague term that may relate to any abnormal process in the pulmonary arterial system, however, pulmonary arterial hypertension is a very specific disorder that is defined by an elevated mean pulmonary arterial pressure, a normal wedge pressure, and an elevated pulmonary vascular resistance. these are measured by doing a right heart catherization.
