摘　　要：目的:通过定量组织速度成像技术(quantitative tissue velocity imaging,QTVI)与冠状动脉造影术(se-lected coronary angiography,SCA)定位冠心病狭窄冠状动脉分支的对比研究,探讨定量组织速度成像技术诊断冠心病的临床价值。材料与方法:对122例拟行经皮冠状动脉介入术(Percutaneous coronary intervention,PCI)前常规行定量组织速度成像技术检查,节段性室壁运动异常(Regional wall motion abnor mality,RWMA)应用左室16节段分法定位并与冠状动脉造影进行比较。结果:①定量组织速度成像技术诊断室壁节段性运动异常准确性85.3%,敏感性85.7%,特异性80%。②检出冠状动脉狭窄敏感性左前降支74.4%,左回旋支51.7%,右冠状动75.0%,左前降支和右冠状动脉的敏感性高于左回旋支(P<0.05)。③检出单支、双支、三支狭窄的敏感性分别为71.8%,76.3%,82.1%,QTVI与SCA检出冠脉单支、双支及多支病变无统计学意义(P<0.05)。结论:定量组织速度成像技术检测节段性室壁运动异常可以准确诊断狭窄冠状动脉分支,是临床评价心肌缺血和(或)心肌梗死的可靠而敏感方法。Purpose：Contrast research positioning coronary artery heart disease different branch coronary angiography with quantitative tissue velocity imaging and quantitative tissue velocity imaging,Study on quantitative tissue velocity imaging diagnosis coronary artery heart disease.Materials and Methods：Regular check with quantitative tissue velocity imaging 122 cases before percutaneous coronary intervention,Orientation regional wall motion abnor mality with Left room 16 segment model,contrastwith Quantitative tissue velocity imaging.Results：Quantitative tissue velocity imaging diagnosis Regional wall motion abnormality Accuracy 85.3%,Sensitivity 85.7%,Specificity 80%.Detection narrow coronary accuracy Left anterior descending artery74.4%,Left circumflex 51.7%,Right coronary artery75.0%,Left anterior descending artery and Right coronary artery higher than Left circumflex.Sensitivity of one Branch.two Branch.three Branch are71.8%,76.3%,82.1%,Detection Coronary Lesions of one Branch.two Branch.three Branch was no statistically significant,with quantitative tissue velocity imaging and myocardial infarction.Conclusion：Quantitative tissue velocity imaging can detect regional wall motion abnormality and accurate diagnosis of coronary angiography stenosis,Assessment of myocardial ischemia in clinical and（or） myocardial infarction reliable and sensitive method.
