Perioperative care in patients with pulmonary hypertension after cardiac surgery: clinical management, outcome and future clinical research. Results from an expert meeting.

摘要

Pulmonary hypertension (PH) is defined as a haemo-dynamic and pathophysiological condition, characterized by an increase in mean pulmonary arterial pressure (mPAP) >=25 mm Hg at rest, as assessed by right heart catheterization. PH encompasses multiple disease subtypes. The 5 major groups, according to the updated WHO classification, are: (1) pulmonary arterial hypertension (PAH); (2) PH owing to left heart disease; (3) PH owing to lung diseases and/or hypoxaemia; (4) chronic thromboembolic PH, and (5) PH with unclear multifac-torial mechanisms [1].
