| 摘 要： | 目的 应用实时三维超声心动图(RT-3DE)评价陈旧性心肌梗死患者左心室收缩同步性与收缩功能,并探讨左心室收缩同步性对左心室整体及局部收缩功能的影响.方法 对陈旧性心肌梗死组30例(心梗组,其中陈旧性前壁心梗14例)及20名正常人(正常组)行RT-3DE检查,通过脱机软件分析整体及节段容积-时间曲线,获取左心室整体及节段收缩功能参数、左心室收缩同步性参数.结果 心梗组左心室ESV、EDV显著大于正常组(P＜0.01),LVEF显著小于正常组(P＜0.001).心梗组左心室16及12节段收缩同步性参数显著大于正常组(P＜0.001),且均与LVEF呈负相关,其中Tmsv-16-SD%、Tmsv-16-Dif%相关性最高,r值分别为-0.755、-0.747.前壁心梗组梗死节段及邻近节段rEF、rgEF显著减低(P＜0.05),Tmsv%明显延长(P＜0.05),部分未梗死节段Tmsv%出现不同程度缩短,但差异无统计学意义,且前壁心梗组Tmsv% 明显延长的节段与rEF、rg-EF明显减低的节段基本呈对应关系.结论 RT-3DE能定量评价心肌梗死患者左心室收缩同步性及收缩功能,左心室不同步运动可影响左心室收缩功能.

| Abstract: | Objective To assess left ventricular systolic synchrony and systolic function,as well as the relationship between left ventricular systolic synchrony and systolic function in patients with myocardial infarction with real-time three-dimensional echocardiography(RT-3DE).Methods Thirty patients with myocardial infarction and 20 healthy subjects underwent RT-3DE.Full-volume imaging was performed and the data was analyzed.A series of global and regional left ventricular volume curves were plotted.The parameters ... |
