妊娠合并肺动脉高压(pulmonary arterial hypertension,PAH)是一种严重的产科合并症,因孕期心脏负荷增加,孕产妇病死率高。WHO将静息状态下肺动脉平均压>25mmHg和(或)肺动脉收缩压>30mmHg或运动时肺动脉平均压>30mmHg作为诊断标准,最常以肺动脉收缩压≥30mmHg作为标准~([1])。根据肺动脉压力,PAH分为轻、中、重度,轻度指
Pregnancy complicated pulmonary arterial hypertension (PAH) is a serious obstetric complication, due to increased cardiac load during pregnancy, high maternal mortality. The WHO standard resting pulmonary hypertension> 25mmHg and / or pulmonary artery systolic blood pressure> 30mmHg or exercise average pulmonary artery pressure> 30mmHg as the diagnostic criteria, the most common pulmonary artery systolic blood pressure ≥ 30mmHg as the standard ~ ([1]). According to pulmonary artery pressure, PAH is divided into mild, moderate, severe, mild refers to
