目的对比心电图和冠状动脉造影在冠心病不稳定型心绞痛中的诊断结果。方法 156例拟诊冠心病不稳定型心绞痛的患者为研究对象,使用心电图机检查,记录心电图结果,并行冠状动脉造影检查,对两种方式的诊断结果进行对比。结果 156例患者中,心电图检查正常28例,异常128例;冠状动脉造影诊断正常36例,异常120例;两种检查方法诊断结果比较,差异无统计学意义(P>0.05)。心电图检查同冠状动脉造影的符合率为88.5%(138/156),冠状动脉造影中心电图检查正常符合23例,异常符合115例。结论心电图检查操作简便,适合作为该病的初步检查手段,异常时仍需要通过冠状动脉造影来确诊结果,以减少误诊、漏诊的发生。
Objective To compare the diagnostic results of electrocardiogram and coronary angiography in patients with unstable angina pectoris. Methods One hundred and sixty-five patients with unstable angina pectoris diagnosed as CHD were enrolled in this study. The electrocardiogram (ECG) test, ECG and coronary angiography were performed to compare the diagnostic results of the two methods. Results Among the 156 patients, electrocardiogram was normal in 28 cases and abnormal in 128 cases. Coronary angiography was normal in 36 cases and abnormal in 120 cases. There was no significant difference between the two methods in diagnosis (P> 0.05). The coincidence rate of electrocardiogram and coronary angiography was 88.5% (138/156). Electrocardiographic examination of coronary artery was normal in 23 cases and abnormal in 115 cases. Conclusions ECG examination is simple and convenient, suitable as a preliminary examination of the disease, the abnormal still need to confirm the results by coronary angiography to reduce the misdiagnosis and missed diagnosis.
