Pulmonary Arterial Hypertension - PAH

Pulmonary arterial hypertension (PAH) is defined as a mean pulmonary artery pressure (mPAP) >25 mm Hg in the setting of normal or reduced cardiac output and a normal pulmonary capillary wedge pressure. Most commonly, PAH is secondary and associated with other disorders such as left heart disease, lung disease, or chronic thromboembolic disease. PAH can also be a primary process, either inherited or idiopathic.
