摘要 目的:探讨实时三平面定量组织速度成像技术对评价冠心病患者左右心室壁收缩同步运动的临床价值。方法:同步实时采集行冠脉造影139例患者(分4组)心尖四腔观、心尖两腔观和心尖左室长轴观的组织速度动态图像,测量左右心室壁基底段收缩达峰时间(Ts)并计算室内及室间收缩不同步差量进行对比研究。结果:部分左室壁基底段Ts在组间比较中有统计学差异(P<0.01或P<0.05),室内及室间收缩不同步差量的组间比较无统计学差异(P>0.05),室间隔Ts对冠状动脉狭窄≥50%的诊断价值最高(P<0.01)。结论:实时三平面定量组织速度成像技术可较准确评价心室壁收缩同步运动,对诊断缺血心肌的敏感性高于常规超声心动图。

AbstractObjective: To investigate the clinical value of real-time 3-plane quantitative tissue velocity imaging in ventricular systolic synchrony of coronary heart disease(CHD). Methods: 139 cases proved by coronary angiography were selected for synchronous real-time dynamic image acquisition of tissue velocity imaging, including apical 4-chamber view, apical 2-chamber view and long axis of left ventricle(LV) view. Then parameters such as time of systolic velocity(Ts) in the left and right ventricular walls’ basal segments were measured, and intraventricular and interventricular systolic dyssynchrony was compared. Results: Ts show significant difference in several LV walls’ basal segments among different groups(P<0.01 or P<0.05). Intraventricular and interventricular systolic dyssynchrony had no significant difference(P>0.05). The ventricular septum Ts had the maximum diagnostic value on coronary artery stenosis when the stenosis was larger than 50%(P<0.01). Conclusion: The real-time 3-plane quantitative tissue velocity imaging used in evaluation of ventricular systolic synchrony has higher sensitivity than conventional echocardiography in the diagnosis of myocardial ischemia.
