目的应用心脏磁共振（CMR）技术评价肺动脉高压（PH）患者的右心室功能障碍，设计对192例已知或疑似PH患者行右心导管插入术和CMR的回顾性队列研究。PH定义为平均肺动脉压>= 25 mm Hg。RV射血分数（RVEF）异常定义为：
Objective To evaluate segmental right ventricular (RV) dysfunction in pulmonary hypertension (PH) using cardiac magnetic resonance (CMR).Design Cross-sectional analysis in a retrospective cohort of consecutive adult patients.Setting Mount Sinai Hospital in New York.Patients 192 patients with known or suspected PH undergoing right heart catheterisation and CMR. PH was defined as mean pulmonary artery pressure >= 25 mm Hg. Abnormal RV ejection fraction (RVEF) was defined as
