超声心动图对冠状动脉硬化性心脏病的诊断价值--与冠状动脉造影对比

目的：通过对冠心病（ＣＡＤ）的超声心动图（ＥＣＨＯ）与冠状动脉造影对比，来探讨ＥＣＨＯ对ＣＡＤ诊断的价值。方法对７１例ＣＡＤ进行ＥＣＨＯ检查，并与造影进行对比，结果ＥＣＨＯ对ＣＡＤ诊断的敏感性较低，单枝、多枝病变和总的阳性率分别为３５．７％，６５．１％和５３．５％；ＥＣＨＯ阳性患的ＣＡＤ病变程度较为严重，且多为多枝病变，其狭窄程度〉９０．０％；如果为单枝病变，则冠状动脉（ＣＡ）的狭窄程度已接近团

Value of echocardiography in the diagnosis of coronary artery disease compared with coronary arteriography

AIM To investigate the value of echocardiography (ECHO) in the diagnosis of coronary artery disease (CAD) in comparison with coronary arteriography (CAG). METHODS ECHO was performed in 71 cases of patients with CAD and compared with CAG. RESULTS ECHO had a considerably low sensitivity for CAD in the diagnosis, 35.7% for 1 vessel CAD and 65.1% for multiple vessel CAD. The total sensitivity of ECHO for CAD diagnosis was 53.5%. When ECHO was positive, the CAD diagnosed tended to be multiple vessel and the degree of stenosis was usually over 90 0%. The CAD diagnosed was a 1 vessel case, the main coronary artery might have been completely or almost completely occluded. Moreover, the patients with positive ECHO had a higher Gensini's scores than subjects with negative ECHO (53.5 vs 13.3, P <0.01): the WMS was significantly positively correlated with Log (1+Gensini's scores). ECHO was always found to be negative if the atherosclerosis was mainly involved in right coronary artery. CONCLUSION Although sensitivity of ECHO in the diagnosis for CAD is considerably low, its value in evaluating the severe degree of CAD has to be paid more attention to.
