对象和方法:Ⅰ组MI40例,Ⅲ组冠心病(CAD)心绞痛45例、Ⅲ组无心脏病者40例,性别年龄三组匹配。应用77020 AC彩超仪,常规检查后按九段划分法规察左室壁运动,用ME测量室壁运动幅度,取呼气末3个心动周期的均值,将9段归为左室前壁及后壁,检查前3天停药治疗。结果:RWMA三组检出率分别为100％,93.3％和0;临床诊断有无CAD和UCG检测有无RWMA,97.6％吻合、2.4％不吻合;左室壁运动幅度(MM),有RWMA的前壁和后壁Ⅰ、Ⅱ组分别为3.0±1.9、4.4±1.0(p<0.01)和6.8±1.9、
Subjects and Methods: Group Ⅰ MI 40 cases, Ⅲ group 45 cases of coronary heart disease (CAD), Ⅲ group 40 cases without heart disease, gender age three groups match. Application of 77020 AC color Doppler ultrasound, routine examination according to nine sections of law to observe the left ventricular wall motion measurement with ME chamber wall amplitude, taking end-expiratory mean of three cardiac cycles, the 9-segment left ventricular anterior wall and posterior wall , Check the first 3 days before stopping treatment. Results: The detection rates of three groups of RWMA were 100%, 93.3% and 0 respectively. The clinical diagnosis of CAD and UCG with and without RWMA were 97.6% and 2.4%, respectively. The amplitude of left ventricular wall motion (MM) The anterior wall and posterior wall in group Ⅰ and Ⅱ were 3.0 ± 1.9, 4.4 ± 1.0 (p <0.01) and 6.8 ± 1.9 respectively,
