摘要
目的 探讨肺心病患者左心室功能损害程度与肺动脉高压水平的相关性。方法 用彩色多普勒超声心动图测量 4 5例肺心病患者心脏结构和功能参数 ,并进行直线相关分析。结果 右心室、左心室收缩末期面积比与肺动脉收缩压呈显著正相关 (r =0 .6 3,P <0 .0 5 ) ,二尖瓣E峰、A峰积分比与肺动脉收缩压呈显著负相关 (r =- 0 .5 6 ,P <0 .0 5 ) ,左心室收缩期偏心指数与肺动脉收缩压呈显著负相关 (r =- 0 .6 0 ,P <0 .0 5 )。
Objective To explore the correlation between the pulmonary arterial systolic pressure in patients with cor pulmonale and the left ventricular functional impairment.Methods Cardiac structures and functional parameters of 45 cases were detected with color Doppler echocardiograph and the results underwent linear correlation analyses.Results Obvious positive correlation (r=0.63,P<0.05) was found between the pulmonary arterial systolic pressure and the ratio of left and right ventricular end systolic areas.Obvious negative correlation existed between the pulmonary arterial systolic pressure and the ratio of mitral Peak A and Peak E areas(r=-0.60,P<0.05).Conclusion Obvious correlation exsits between the pulmonary arterial systolic pressure and the left ventricular functional impairment.
