Panelists discuss how pulmonary arterial hypertension diagnosis requires comprehensive evaluation including right heart catheterization to confirm hemodynamic criteria, with normal mean PA pressure being ≤20 mmHg and the need to rule out other causes of pulmonary hypertension.

Panelists discuss how the pathophysiology of pulmonary arterial hypertension involves complex mechanisms across multiple genetic and treatment pathways, with over 20 identified genes and four major therapeutic targets including nitric oxide, endothelin, prostacyclin, and activin signaling inhibition.
