Pulmonary Arterial Hypertension
📋Overview
Pulmonary arterial hypertension (PAH) is a progressive condition characterized by elevated blood pressure in the pulmonary arteries, leading to increased resistance to blood flow from the right side of the heart to the lungs. It is a specific subgroup of pulmonary hypertension involving the small pulmonary arterioles and is distinct from other forms caused by left heart disease or lung diseases. PAH can be idiopathic, heritable, or associated with other medical conditions.
