摘　　要：目的探讨定量组织速度成像(QTVI)对冠心病患者的左室心肌的局部功能评价价值。方法 53例患者根据冠脉造影结果将其分为:冠状动脉无狭窄病变对照组(n=14)及单支病变组(n=12)、双支病变组(n=16)和三支病变组(n=11)。所有患者在冠状动脉造影术前在心肌组织多普勒曲线上测量最大收缩期峰值速度和峰值位移。结果在左室长轴、心尖四腔、心尖两腔不同切面上,双支、三支病变左室不同节段的收缩峰速度和峰值位移均低于无狭窄病变对照组(P<0.01),而单支组与无狭窄病变对照组之间比较无统计学差异。结论定量组织速度成像可以敏感地评价冠心病患者左室心肌的局部功能。Objective To assess the value of quantitative tissue velocity imaging（QTVI） in evaluating regional systolic function in different degrees of coronary artery stenosis.Methods Fifty-three patients were divided into control group and signal vessel involved group,double vessel involved group,triple vessel involved group according to angiocardiography.The peak systolic velocity and the peak displacement of basal segment,middle segment of left ventricular wall motion were obtained by QTVI.Results The peak systolic velocity and the peak displacement of basal segment,middle segment of patients with double,triple coronary artery lesion were lower than those of patients without coronary artery stenosis（P0.01）.No significant difference of the peak systolic velocity and the peak displacement of basal segment,middle segment was found between the control group and the signal vessel involved group.Conclusion QTVI can sensitively evaluate left ventricular local systolic function in patients with coronary heart disease.
