目的 运用实时三维超声心动图(RT3DE)研究冠心病三支冠状动脉病变患者左室收缩功能(LVEF)与同步性的关系.方法 应用实时三维超声心动图将40例经选择性冠状动脉造影证实的三支冠状动脉病变患者分为陈旧性心肌梗死组(OMI,n=20)和非心肌梗死组(nMI,n=20),对其左室舒张末期容积(LV-EDV)、左室射血分数(LVEF)、16节段达峰时间标准差(Tmsv 16-SD)及其最大差值(Tmsv16-Dif)进行研究,并与20例正常人进行比较.结果 与对照组相比,冠心病患者LVEDV、Tmsv 16-SD、Tmsv16-Dif增加,LVEF降低,差异均有统计学意义(P＜0.01)；与非心肌梗死组对比,OMI组LVEDV、Tmsv16-SD、Tmsv16-Dif增加,LVEF降低,差异有统计学意义(P＜ 0.01)；冠心病患者Tmsv16-SD、Tmsv16-Dif与LVEF显著负相关(分别为r=-0.594,r=-0.498,P＜0.01).结论 冠心病三支病变引起左心室重构,陈旧性心肌梗死左心室重构甚重于非心肌梗死患者；冠心病左室收缩同步性指标一定程度上能够反映左室收缩功能.

Objective To study the relations between left ventricular ejection fraction (LVEF) and contractive synchronism in patients with three-vessels coronary artery disease by real-time three-dimensional echocardiography (RT3DE).Methods Forty patients with three-vessel disease coronary artery disease (CAD) and 20 patients without CAD confirmed by selective coronary angiography were choosed.CAD patients were divided into old myocardial infarction group (OMI,n =20) and non-myocardial infarction group(nMI,n =20).The left ventricle end-diastole volume(LVEDV),ejection fraction (LVEF),the 16 segments and those standard deviation (Tmsv16-SD),the maximal difference of time among all 16 segments (Tmsv16-Dif) were measured by RT3DE.Results Compared with control group:LVEDV,Tmsv16-SD and Tmsv16-Dif were significantly increased,LVEF was significantly decreased in CAD patients (P ＜0.01).Compared with nMI group,the same change happened in OMI group (P ＜ 0.05).In CAD patients group,LVEF was negatively correlated with Tmsv16-SD (r =-0.594,P ＜ 0.01)and Tmsv16-Dif (r =-0.498,P ＜ 0.01).Conclusions Left ventricular remodeling is resulted in three-vessel disease.The left ventricular remodeling in OMI outweights nMI.Left ventricular contractive synchronism index can reflect left ventricular systolic function in certain degree.
