Updated clinical classification of pulmonary hypertension

• Jung HO

Abstract

Pulmonary hypertension is a hemodynamic and pathophysiological condition defined as an increase in mean pulmonary arterial pressure > or =25 mmHg at rest as assessed by right heart catheterization. Clinical conditions of pulmonary hypertension are classified into 6 clinical groups with different pathological, pathophysiological, prognostic and therapeutic features. The treatment strategy is remarkably different among 6 clinical groups. Group 1 (pulmonary arterial hypertension) is the only clinical group with specific drug therapy and an evidence-based treatment algorithm is provided. Following descriptions are about the clinical classification of pulmonary hypertension updated at 4th World symposium of pulmonary hypertension held in 2008.
