Abstract:
ObjectiveTo investigate the influence of r egional wall motion abnormality(RWMA) on cardiac anatomic structure with coronary artery disease (CAD) and to recognize serious degree of the disease by echocardiography. MethodsA total of 125 cases was observed. There were 63 patients in CAD group (41 cases with general CAD,7 cases with acute myocardial infarction and 15 cases with old myocardial infarction). All the patients had undergone respectively CABG,PTCA and stent,coronary angiography or radionuclide scan for confirmation. There were 62 cases in normal control group. Using 2D echocardiography,stand short and long axis images of left ventricle(LV) were chosen. Displayed RWMA to compose the centripetal disharmonized motion with whole-wall of LV,and the discentripetal contradiction motion. M mode for continuous scan was to detect the typical characterisitic of RWMA. ResultsSingle-occurring RWMA from 43 cases ( 68.2 %) in 63 cases with CAD was displayed, while multiple-occurring RWMA from another 20 cases ( 31.8 %) was displayed(P
