摘　　要：目的　探讨多普勒组织声像图 (DTI)与解剖M型超声心动图对冠心病病变段诊断的异同。方法　本文对2 8例经冠脉造影 (CAG)确诊的冠心病用频谱勒组织声像图(DT PW )测定其室壁运动频谱 ,以收缩波S≤ 5cm/s为病变节段 ,用解剖M型法测定收缩期室壁增厚率 ,以 <30 %为病变节段 ,两种方法均和CAG证实的病变节段对比。结果　DTI法诊断冠心病病变段敏感性为 74 6 0 % ,解剖M型法39 6 8% ,病变段收缩波 (S)低平 ,时相延迟 ,方向相反或频谱紊乱 ,后两种情况多见于梗死节段 ;室壁增厚率降低 ,甚至为负数。结论　DTI法对冠心病的诊断较解剖M型法敏感 ,可成为诊断冠心病的一种辅助方法。Objectives The aim of this study is to asses the differences on the diagnosis of coronary disease (CAD) by Doppler tissue imaging (DTI) and Anatom M mode Echocardiograph in 28 confirmed CAD patients, The findings of regional wall motion abnormalities and regional ventricular wall thickening fractions less than 30% were compared with CAG. Results Susceptibility of pulsed DTI was 74.60% for diagnosis of ischemic segment of CAD, Anatom M mode Echocardiography is 39.68%; the velocity of systolic wave of ischemic segment was lower、delayed, with their direction opposite or disordered; the ventricular wall thickening fractions was reduce, hte values were negative number. Conclusions pulsed DTI is sensitive in comparison with Anatom M mode Echocardiography for diagnosis of coronary artery disease, It can be regarded as one of supplementary methods for diagnosis of coronary artery disease.
