摘要
应用脉冲式或连续式多普勤超声技术,对18例海拔3200m高原正常人及25例高原性心脏病(HAHD)患者测定其肺动脉压。正常组及HAHD无瓣膜返流组10例(40%)应用Haham回归方程,PAMP分别为2.84±0.4及3.73±0.57(lkPa=7.5mmHg);HAHD有三尖瓣返流组8例(32%)用TRPG法测得PASP为6.13±1.73kPa;HAHD有肺动脉瓣返流组7例(28%)用PRPG法测得PADP为4.0±0.73kPa。表明多普勒超声技术的不同方法可用于不同病理状态上高原低氧性肺动脉高压的测定,并揭示了出现瓣膜返流改变时高原低氧性肺动脉高压的程度。
he pulmonary artery pressure was evaluated by Doppler echocardiography in l8 healthy native su5jects at high altitude and 25 cases of high altitude heart disease(HAHD).Wifh Haham’s regressive formula,PAMP=(79-0.45×AT),PAMP was 2.84±0.lkPa in healthy subjectsand 3. 73±0.57in l0 cases of HAHD without valve reguritation(40%); PASP was 6.13±1.73kPa in 8 cases of HAHD with tricusPid regurgitation(32%)by TRPG method; PADP was 4.0±0.73kPa in 7 cases of HAHD with pulmonary regurgitation(28%)by PRPG method. The con-clusion was that the different methods of Doppler echocardiography can be used for cvaluating hy-poxic pulmonary hypertension at various pathologic stages,and the exrent of high altitudc hypoxicpulmonary hypertension which caused valve rcgurgitation was shown.
