动态心电图检查与常规心电图检查在冠心病诊断中的价值比较

Comparison of value of dynamic electrocardiogram examination and routine electrocardiogram examination in diagnosis of coronary heart disease

目的:比较动态心电图检查与常规心电图检查在冠心病诊断中的价值。方法:回顾性分析2021年6月至2024年5月于该院就诊的60例疑似冠心病患者的临床资料。患者均行动态心电图检查、常规心电图检查以及冠状动脉造影检查,以冠状动脉造影检查为金标准,比较动态心电图检查与常规心电图检查诊断冠心病的效能(准确度、灵敏度、特异度);采用Kappa一致性检验,比较动态心电图检查、常规心电图检查与冠状动脉造影检查诊断结果的一致性。结果:冠状动脉造影检查结果显示,60例疑似冠心病患者确诊为冠心病44例,非冠心病16例;动态心电图检查诊断冠心病的准确度为93.33%,高于常规心电图检查的78.33%,差异有统计学意义(P<0.05);动态心电图检查诊断冠心病的灵敏度为95.45%,高于常规心电图检查的81.82%,差异有统计学意义(P<0.05);Kappa一致性检验结果显示,动态心电图检查与冠状动脉造影检查诊断冠心病结果的一致性(Kappa值=0.830,P<0.05),高于常规心电图检查与冠状动脉造影检查诊断结果的一致性(Kappa值=0.477,P<0.05)。结论:动态心电图检查诊断冠心病的准确度和灵敏度以及与冠状动脉造影检查诊断结果的一致性均高于常规心电图检查。

Objective:To compare value of dynamic electrocardiogram examination and routine electrocardiogram examination in diagnosis of coronary heart disease.Methods:The clinical data of 60 patients with suspected coronary heart disease who were treated in this hospital from June 2021 to May 2024 were retrospectively analyzed.All patients underwent dynamic electrocardiogram examination,routine electrocardiogram examination and coronary angiography.Using the coronary angiography as the gold standard,the efficiencies(accuracy,sensitivity and specificity)of dynamic electrocardiogram examination and routine electrocardiogram examination in the diagnosis of coronary heart disease were compared.Kappa consistency test was used to compare the consistencies of the results of dynamic electrocardiogram examination and routine electrocardiogram examination in the diagnosis of coronary heart disease with the results of coronary angiography.Results:The coronary angiography showed that 60 patients with suspected coronary heart disease were diagnosed as coronary heart disease in 44 cases and non-coronary heart disease in 16 cases.The accuracy of dynamic electrocardiogram examination in the diagnosis of coronary heart disease was 93.33%,which was higher than 78.33%of routine electrocardiogram examination,and the difference was statistically significant(P<0.05).The sensitivity of dynamic electrocardiogram examination in the diagnosis of coronary heart disease was 95.45%,which was higher than that of routine electrocardiogram examination(81.82%),and the difference was statistically significant(P<0.05).Kappa consistency test results showed that the consistency of dynamic electrocardiogram examination and coronary angiography in the diagnosis of coronary heart disease(Kappa value=0.830,P<0.05)was higher than that of conventional electrocardiogram examination and coronary angiography(Kappa value=0.477,P<0.05).Conclusions:The accuracy and the sensitivity of dynamic electrocardiogram examination in the diagnosis of coronary heart disease and the consistency with the results of coronary angiography are higher than those of routine electrocardiogram examination.
