| 摘 要： | 目的采用实时三维超声心动图(real time three-dimensional echocardiography,RT-3DE)评价缺血性二尖瓣反流(ischemic mitral regurgitation,IMR)的左室(left ventricle,LV)重构。方法选取30例IMR患者(IMR组),30例单纯冠心病(coronary arteray disease,CAD)患者(CAD组)及36例正常人(对照组),采集RT-3DE全容积图像,下线分析LV整体和17节段的容积及射血分数(ejection fraction,EF);测量LV舒张末期球形指数(sphericity index,SI),三组间比较并分析IMR的独立预测因子。结果对照组、CAD组和IMR组的LV整体容积,基底段、中间段和下后壁容积均依次增大;IMR组SI增大;IMR组的下后壁EF低于CAD组。LV舒张末期容积、下后壁容积和SI是IMR的独立预测因子。结论 RT-3DE可有效评价LV重构。IMR的LV整体重构和局部重构更加严重,形态趋于球形,并伴下后壁的功能异常。

| Abstract: | Objective The left ventricular(LV) global and regional volume and function were measured with real time three-dimensional echocardiography(RT-3DE) to evaluate left ventricular remodeling pattern in patients with ischemic mitral regurgitation(IMR).Methods RT-3DE was performed in 30 patients with significant IMR(IMR group),30 patients with coronary artery disease but no IMR(CAD group) and 36 healthy subjects(Control group).The LV global and regional(17 segments) volume and ejection fraction(EF) were analyzed ... |
