超声心动图评价肺动脉高压患者左右心功能的应用价值

Echocardiographic evaluation of pulmonary arterial hypertension in patients with left ventricular functiona pplication value

目的:探讨超声心动图评价PAH患者左右心功能的应用价值,进一步观察PAH患者心功能变化。方法:选取我院诊治的PAH患者(PAH组)及门诊健康体检者各60例为研究对象(对照组),采用超声心动图测量患者左心室及右心室相关指标。结果:PAH组心肌做功指数(Tei指数)、右心室收缩末期面积(RVESA)、右心室舒张末期面积(RVEDA)明显高于正常对照组,右心室面积变化率(RVFCA)低于正常对照组,比较差异具有统计学意义(P<0.05);PAH组左心室舒张末期容积(LVEDV)、左心室收缩末期容积(LVESV)、收缩期峰值运动速度(Sm)、二尖瓣口舒张早期血流速度(Em)、舒张晚期峰值流速(Am)明显低于正常对照组,比较差异具有统计学意义(P<0.05);左心室射血指数(LVEF)、左心室输出量(CO),两组比较差异无统计学意义(P>0.05)。结论:PAH患者采用超声心动图对患者左右心功能能进行有效评价,患者心功能表现为左心室舒张功能及心肌收缩功能受损、右心舒张及收缩功能降低。

Objective：To investigate the echocardiographic evaluation of pulmonary arterial hyper- tension （PAH） in patients with left ventricular function application value, and to observe changes in cardi- ac function was observed in patients with PAH. Methods. Sixty PAH patients （PAH group） and 60 healthy volunteers （control group） were selected for the study, left ventricular and right ventricular relat- ed indicators were measured by echocardiography. Results： Tei index and right ventricular end-systolic area （RVESA） of the right ventricular end-diastolic area （RVEDA） was significantly higher than that of the healthy control group, but RVFCA was lower than the control group, the difference was statistically sig- nificant （P 〉 0. 05 ）; PAH group showed significant lower left ventricular end-diastolic volume （LVEDV） , left ventricular end-systolic volume （LVESV）, peak systolic velocity （Sm）, early diastolic mitral flow velocity （Em）, late diastolic peak velocity （Am） than the control group, the difference was statistically significant（P〈0.05）, LVEF and CO were not significant different between the two groups （P〈0. 05）. Conclusion. The performance of cardiac function can be effectively evaluated by echocardio- graphy, PHA patients showed systolic and diastolic ventricular dysfunction.
