冠状动脉造影与体表心电图在冠心病诊断中的对比分析

COMPARATIVE ANALYSIS OF CORONARY ARTERIOGRAPHY AND BODY SURFACE ELECTROCARDIOGRAM IN THE DIAGNOSIS OF CORONARY HEART DISEASES

目的 了解冠状动脉造影与体表心电图在冠心病诊断中的价值。方法 根据临床症状、心电图、酶变化,选择初诊为冠心病的患者36例,采用Judkins法进行左、右冠状动脉造影,并与体表心电图对比。结果 36例患者中,冠状动脉造影异常者24例,占67%,正常者12例,占33%。结论 体表心电图简便、常用,能够帮助诊断大多数冠心病,但存在假阳性和假阴性。冠状动脉造影具有特异性,也有局限性和风险。必须全面分析患者的资料,选择性的实施冠状动脉造影,以减少冠心病的误诊及滥治现象。

Objective To understand the value of coronary arteriography and body surface electrocardiogram(ECG) in the diagnosis of coronary heart diseases.Methods According to clinical symptoms and changes of ECG and enzymes,we chose 36 patients who were first diagnosed as having coronary heart diseases.Then the arteriography of both left and right coronary arteries was done on them,using Judkins' method and compared with body surface ECG.Results Of all the 36 patients,24 cases were abnormal in coronary arteriography(67%),and 12 cases normal(33%).Conclusion The simple,frequently used body surface ECG can help diagnose most coronary heart diseases,but there can be false positive and false negative reactions.Coronary arteriography has its specificity and also has some limitations and risks.And therefore,the patients' data must be analysed thoroughly and selective coronary arteriography must be carried out so as to reduce the misdiagnosis and abusive treatment of the disease.
