| 摘 要： | 目的观察采用二维斑点追踪超声心动图(2D-STE)评估冠状动脉病变对收缩早期左心室心肌运动影响的可行性。方法将179例接受冠状动脉造影检查的可疑冠心病患者的左心室心肌节段按供血冠状动脉狭窄程度分为对照组(无狭窄)、轻度组(狭窄程度≤50%)、中度组(50%<狭窄程度<75%)和重度组(狭窄程度≥75%)。采用2D-STE分析各组左心室心肌节段纵向预拉伸峰值应变(LPSS)和圆周预拉伸峰值应变(CPSS)的差异。结果左心室各层心肌LPSS和CPSS峰值于收缩早期出现,轻度组均最高(P均<0.05),中度组最低(P均<0.05);冠状动脉轻度狭窄时收缩早期左心室心肌拉伸运动加强,随着冠状动脉病变加重而逐渐减弱。结论2D-STE可无创评估冠状动脉病变对收缩早期左心室心肌运动的影响。

| Abstract: | Objective To explore the feasibility of two-dimensional speckle tracking imaging echocardiography(2D-STE)in evaluation of the impact of coronary artery lesions on left ventricular myocardial movement in early systolic stage.Methods A total of 179 patients with suspected coronary heart disease who underwent coronary angiography were collected,and left ventricular heart sarcomeres of all patients were divided into control group(no stenosis),mild group(stenosis≤50%),moderate group(50%
