心电图、核素心肌显象及冠脉造影诊断冠心病的结果对比分析

Comparative study between ECG,ECT and coronary angiography for diagnosing coronary heart disease

本文将３６例冠心病患者的心电图（ＥＣＧ）、核素心肌显象（ＥＣＴ）及冠脉造影结果进行了对比分析，结果显示诊断冠心病的敏感性和特异性ＥＣＧ为８６．９％和５３．９％，ＥＣＴ为９５．７％和６９．２％。对冠脉各主要分支病变检出率，ＥＣＴ也达９０％左右。提示ＥＣＴ对冠心病诊断具有较高敏感性；阴性的ＥＣＴ检查结果可以基本排除明显的心肌缺血。

Abstract Among 36.patients who had performed coronary arteriography, 23 patient,were diagnosed as coronary artery disease and 13 patients with normal coronary arteriogram. Their ECG and ECT were evaluated and compared with coronary angiography The results showed sensitivity and specificity of ECG were 86. 9% and 53.9%,and ECT were 95.7% and 69.2% respectively. In detecting the sites of coronary artery disease the sensitivity of ECT,which was more sensitive than ECG,was about 90%. This study indicates that ECT provides a better sensitivity than ECG for detecting coronary heart disease, and a negative ECT can nearly exclude apparent myocardial Ischemia.
