摘要

Chronic thromboembolic pulmonary hypertension (CTEPH) is a life-threatening condition characterized by a pulmonary vascular bed that is obstructed or obliterated with the organized thrombi, promoting increased pulmonary vascular resistance (PVR), progressive pulmonary hypertension (PH) and right heart failure. In a prospective study following survivors of acute pulmonary embolism, 3.8% of patients developed CTEPH within 2 years. However, up to 40% of patients with CTEPH have not had a clinically apparent acute pulmonary embolic episode. Survival without intervention is poor and proportional to the degree of PH and right ventricular dysfunction at the time of diagnosis. In one study, the 5-year survival rate in patients with CTEPH was 30% when the mean pulmonary artery pressure (PAP) was greater than 40mmHg and 10% when it was greater than 50mmHg
