Pulmonary arterial hypertension (PAH) is a chronic and progressive disorder, defined as a mean pulmonary arterial pressure > 20 mmHg and a pulmonary vascular resistance > 3.0 WU, with a normal capillary wedge pressure of < 15 mmHg. Stenosis of the pulmonary vasculature results in increased pulmonary vascular resistance, right heart failure, and if untreated, death. The World Health Organization (WHO) has divided pulmonary hypertension into five groups on the basis of etiologies. Identifying the underlying cause of pulmonary hypertension is essential for guiding management, limiting adverse events, and improving quality of life.
