摘要
目的比较心电图(Electrocardiogram,ECG)及冠状动脉造影(Coronary Angiography,CAG)诊断冠心病的临床价值。方法选取我院2018年5月至2019年5月行ECG及CAG诊断的冠心病患者共92例,对比ECG与CAG的诊断结果,分析两种方法诊断冠心病的应用价值。结果ECG、CAG诊断冠心病的阳性率分别为80.4%和78.3%,比较差异无统计学意义(P>0.05);以CAG诊断为标准,ECG诊断冠心病的灵敏度、特异度为83.8%和38.9%。ECG诊断冠心病轻度狭窄、中度狭窄、重度狭窄的灵敏度分别为63.2%、92.0%、96.4%;诊断单支病变、双支病变、三支病变的灵敏度分别为94.1%、85.7%、70.6%。结论ECG与CAG诊断冠心病的阳性率相当,但ECG对冠脉轻度狭窄或三支病变诊断的灵敏度较低。
Objective To compare the clinical value of electrocardiogram(ECG)and coronary angiography(CAG)in the diagnosis of coronary heart disease.Methods From May 2018 to May 2019,92 patients with coronary heart disease diagnosed by ECG and CAG in our hospital were selected.The diagnosis results of ECG and CAG were compared,and the value of two methods in the diagnosis of coronary heart disease was analyzed.Results The positive rates of ECG and CAG in the diagnosis of coronary heart disease were 80.4%and 78.3%,respectively,and there was no statistically significant difference(P>0.05).Based on the diagnosis of CAG,the sensitivity and specificity of ECG in the diagnosis of coronary heart disease were 83.8%and 38.9%;the sensitivity of ECG in the diagnosis of mild,moderate,and severe stenosis of coronary heart disease was 63.2%,92.0%,and 96.4%,respectively;the sensitivity of ECG in the diagnosis of single-vessel disease,double-vessel disease,and triple-vessel disease was 94.1%,85.7%,and 70.6%,respectively.Conclusion The positive rates of ECG and CAG in the diagnosis of coronary heart disease are comparable,but the sensitivity of ECG to the diagnosis of mild coronary stenosis or three-vessel disease is low.
