摘　　要：目的观察冠状动脉三支病变和(或)左主干病变患者心脏超声三维斑点整体应变指标与SYNTAX评分及左室射血分数(LVEF)的相关性。方法纳入28例冠状动脉三支病变和(或)左主干病变的冠状动脉粥样硬化性心脏病(冠心病)患者,采用心脏超声三维斑点追踪技术进行心肌运动分析,超声仪自动计算左室整体短轴(GRS)、长轴(GLS)、圆周(GCS)与面积(GAS)应变,采用Simpon法计算LVEF。根据SYNTAX评分标准对纳入患者进行评分。分析三维斑点整体应变指标与SYNTAX评分及LVEF的相关性。结果心脏超声三维斑点整体短轴应变与SYNTAX评分呈负相关(r=-0.508,P<0.05),整体面积应变与SYNTAX评分呈正相关(r=0.569,P<0.05),整体长轴及圆周应变与SYNTAX无相关性(P>0.05)。左心室整体短轴、长轴、圆周与面积应变值均与LVEF具有相关性,相关系数分别为:-0.742、-0.747、0.739、-0.689,P均<0.01。结论心脏超声三维斑点整体应变指标与LVEF及短轴应变、圆周应变与SYNTAX评分具有相关性。Objective To observe the correlation between cardiac three-dimension global strain-speckle tracking imaging （3D-STI） and SYNTAX scores or left ventricular ejection fraction （LVEF） in patients with coronary 3-vessel lesion and/or left main coronary lesion. Methods The patients （n=28） were chosen and given myocardial motion analysis by using 3D-STI. The global radial strain （GRS）, global longitudinal strain （GLS）, global circumferential strain （GCS） and global area strain （GAS） were calculated, and LVEF was calculated by using Simpon method. All patients were given scoring according to SYNTAX score standard. The correlation between 3D-STI indexes and SYNTAX scores or LVEF was analyzed. Results 3D-STI was negatively correlated to SYNTAX scores （r=-0.508, P〈0.05）, GAS was positively correlated to SYNTAX scores （r=0.569, P〈0.05）, and GLS and GCS was not correlated to SYNTAX scores （P〉0.05）. GRS, GLS, GCS and GAS were all correlated to LVEF （r=-0.742, r=-0.747, r=0.739 and r=-0.689, all P〈0.01）. Conclusion 3D-STI indexes and LVEF are correlated to GRS, GCS and SYNTAX scores.
