| 摘 要： | 目的：探讨实时三维超声心动图评价冠心病患者左心室收缩同步性的临床价值。方法：对32例冠心病患者和30例健康体检者进行实时三维超声心动图（RT-3DE）检查，获得左心室收缩同步性指标：Tmsv 16-SD，Tmsv 12-SD，Tmsv 6-SD，Tmsv 16-Dif，Tmsv 12-Dif，Tmsv 6-7Dif。结果：冠心病组左心室收缩同步性指标均大于正常对照组（P〈0．01）。结论：实时三维超声心动图能够评价冠心病左心收缩同步性，为临床提供简便、直观、无创的新方法。

| Abstract: | Objective:To quantitatively evaluate the left ventricular systolic synchronicity in patients with coronary artery disease(CAD) by real-time three-dimensional echocardiography(RT-3DE).Methods:A total of 32 CAD patients and 30 healthy volunteers were enrolled in this study.Full-volume RT-3DE data was acquired.The global and 16-segmental time-volume curves were obtained by the QLAB software(version 4.2).The time to minimal systolic volume in each segment(Tmsv) was taken to derive the following indexes of systolic asynchrony: Tmsv 16-SD,Tmsv 16-Dif,Tmsv 12-SD,Tmsv 12-Dif,Tmsv 6-SD and Tmsv 6-Dif,which meant the standard deviation or the maximal difference of Tmsv among the 16,12 and 6 segments of the left ventricle respectively.Results:Tmsv 16-SD,Tmsv 12-SD,Tmsv 6-SD,Tmsv 16-Dif,Tmsv 12-Dif,Tmsv 6-Dif were all significantly larger in CAD group than those of control group(P<0.01).Conclusion:Left ventricular systolic synchronicity in CAD patients can be accurately determined by RT-3DE. |
