老年冠心病患者心电图与冠状动脉造影对照的临床分析

Analysis of the electrocardiogram and coronary ateriography in elderly patients

目的探讨静息心电图对老年冠心病的诊断价值。方法将224例老年患者的静息心电图与其冠状动脉造影结果进行对比分析。结果冠脉造影阳性180例患者中其心电图阳性157例,阴性23例,敏感性为87.2%;冠脉造影阴性44例患者中其心电图阳性25例,阴性19例,特异性为45.3%。随着冠状动脉病变支数的增加,心电图诊断冠心病的阳性率也越高(P<0.05)。心肌梗死心电图所表现的梗死部位与梗死相关冠状动脉的关系密切。结论静息心电图在老年冠心病诊断中具有一定价值。

Objectives To explore the valve of the resting electrocardiogram（ECG） in diagnosing coronary heart disease（CHD） in elderly patients. Methods 224 elderly patients with CHD were examined by ECG and coronary ateriography（CAG）, and the results were analyzed. Results CAG results were positive in 180 patients and ECG data results were positive in157 and negative in 23 patients.The sensibility was 87.2%. CAG results were negative in 44 patients and ECG data results were positive in 25 of them and negative in 19 patients of them.The specificity was 45.3%. The positive rate of ECG in diagnosing CHD increased with more vessel lesion of coronary artery（P〈 0.05）. ECG of myocardial infarction area closely associated with infarction related coronary artery. Conclusion The valve of the resting electrocardiogram（ECG） is useful in diagnosing coronary heart disease（CHD） in elderly patients.
