摘　　要：目的探讨实时三维超声心动图(RT-3DE)技术评价心肌梗死患者左室17节段局部收缩功能变化与冠状动脉病变相关供血区域的关系。方法 24例健康查体者为正常对照组;26例心肌梗死患者为病变组,经冠状动脉造影(coronary angiography,CAG)检查分为3个亚组:左前降支病变组、左回旋支病变组、右冠状动脉病变组。所有研究对象均行RT-3DE检查,应用QLAB定量分析软件对三维数据库进行定量分析,评价节段射血分数(regional ejection fraction,REF)的异常与梗死相关动脉(infarct relatedartery,IRA)的相关性。结果与对照组相比,心肌梗死部位相应节段局部收缩功能显著下降,而未梗死部位相应节段局部收缩功能代偿性增强,差异有统计学意义(P<0.05)。结论心肌梗死后相关节段REF降低与IRA供血区域高度一致。Objective To explore the relationship between systolic regional fraction （REF） for myocardial infarction（MI） and coronary artery supply blood regions using RT-3DE. Methods RT-3DE was performed in 24 normal subjects and 26 patients with myocardial infarction. REF was obtained by Qlab software from seventeen segmental volume-time curve. Results The REF of MI segments decreased significantly compared with corresponding segments in the normal subjects,and the regional function of non-MI segments increased comparatively. Conclusions The REF of infarct related segments correlate significantly with the supply blood regions determined by IRA.
