三维超声评价心肌梗死患者左室收缩不同步性与整体收缩功能

目的应用三维超声心动图评价心肌梗死患者左室收缩不同步性和整体功能并探讨二者之间的关系。方法应用全容积三维超声心动图对47例心肌梗死患者进行左室16节段收缩同步性检测,同时测量左室整体收缩功能,并与正常对照组比较。结果心肌梗死患者左室16节段不同步参数均与对照组有显著差异,且与左室EF值呈负相关,相关系数为r=-0.659～0.736。结论全容积三维超声能够定量评价心肌梗死患者左室收缩同步性和整体收缩功能,且二者呈负相关。

Assessment of Left Ventricular Systolic Asynchrony and Global Function in Patients with Myocardial Infarction Using Three-dimensional Echocardiography

Objective To assess the left ventricular systolic asynchrony and global function in the patients with myocardial infarction using full volume three-dimensional echocardiography. Methods Myocardial infarctions in fourty-seven patients were studied on Full Volume three dimensional, and 22 normal subjects served as the control. The time-volumetric curves of 17 left ventricular segments and global systolic function were obtained respectively. Results There were significant differences in the asynchrony parameters between the two groups. The EF values were negative correlated with the asynchrony parameters, r=- 0. 659 to 0. 736. Conclusions Threedimensional echocardiography can assess left ventricular systolic asynchrony and global function in the patients with myocardial infarction with negative correlation between them.
