多普勒超声心动图估测的收缩压评估肺高血压

Detection of pulmonary hypertension with systolic pressure estimated by Doppler echocardiography

Int Heart J,2019,60(4):836-844.肺高血压定义为右心导管检查(right heart catheterization,RHC)评估的静息时平均肺动脉压≥25 mm Hg(1 mm Hg=0.133 kPa)。多普勒超声心电图推导的肺动脉收缩压(Doppler echocardiography-derived pulmonary arterial systolic pressure,sPAPECHO)或三尖瓣反流压力梯度(tricuspid regurgitation pressure gradient,TRPG)广泛用于筛查肺高血压。
