<Editors' Choice> Pulmonary Hypertension: Diagnosis, Management, and Treatment
Overview
Affiliations
Pulmonary hypertension (PH) is a hemodynamic state that is characterized by a resting mean pulmonary artery pressure ≧ 25 mmHg. The common forms of PH are pulmonary arterial hypertension (PAH), chronic thromboembolic pulmonary hypertension (CTEPH), PH caused by left-heart disease, and PH due to lung disease. Previously regarded as untreatable, the treatment of PAH has dramatically advanced since the introduction of the drug epoprostenol in 1999, with three-year survival rates improving from 30%-40% to over 85%. Drugs available for the specific treatment of PAH include endothelin-receptor antagonists, phosphodiesterase type 5 inhibitors, soluble guanylate cyclase stimulators, prostacyclin analogs, and prostacyclin-receptor agonists. In the past decade, management and treatment of CTEPH have also improved. While pulmonary endarterectomy used to be the only option for the treatment of CTEPH, newer treatments include a soluble guanylate cyclase stimulator, which has proven to be an efficacious targeted therapy. Other cases benefit from balloon pulmonary angioplasty.
