目的应用实时三维超声心动图(RT-3DE)定量评价冠心病患者的左室收缩功能改变。方法应用RT-3DE测量34例冠心病患者左室舒张末期容积(LVEDV)、收缩末期容积(LVESV)、每搏量(SV)和射血分数(LVEF),并与34例正常人对照。结果冠心病患者的LVEDV、LVESV和SV测值明显大于正常对照组(P<0.001),LVEF明显小于正常对照组(P<0.001);LVEF的减小与LVEDV的增大呈负相关(r=-0.758)。结论应用实时三维超声心动图能准确测量左心室容积和LVEF,能有效评价冠心病左室重构后左室收缩功能状况。
Objective To evaluate the changes of left ventricular systolic function in patients with coronary heart disease by real-time three-dimensional echocardiography (RT-3DE). Methods The left ventricular end-diastolic volume (LVEDV), end-systolic volume (LVESV), stroke volume (SV) and ejection fraction (LVEF) were measured in 34 patients with coronary heart disease by RT- Results The values of LVEDV, LVESV and SV in patients with coronary heart disease were significantly higher than those in normal controls (P <0.001), and LVEF was significantly lower in patients with coronary heart disease than in controls (P <0.001). The decrease of LVEF was negatively correlated with the increase of LVEDV (r = -0.758). Conclusion Real-time three-dimensional echocardiography can accurately measure left ventricular volume and LVEF, and can effectively evaluate left ventricular systolic function after left ventricular remodeling in patients with coronary heart disease.
