Chronic thromboembolic pulmonary hypertension (CTEPH) is a life-threatening complication after acute pulmonary embolism (APE) and is associated with substantial morbidity and mortality. This study aimed to investigate the incidence of CTEPH after APE in Korea and to determine echocardiographic predictors of CTEPH.Among 381 patients with APE confirmed by chest computed tomography (CT) between January 2007 and July 2013, 246 consecutive patients with available echocardiographic data were enrolled in this study. CTEPH was defined as a persistent right ventricular systolic pressure (RVSP) greater than 35 mmHg on echocardiography during follow-up and persistent pulmonary embolism on the follow-up CT.Fifteen patients (6.1
