摘　　要：目的:探讨动态心电图(DCG)联合核素心肌灌注显像(MPI)对冠心病无症状性心肌缺血的诊断价值。方法:严格按照纳入及排除标准,选取2022年1月~2023年1月于天津市第四中心医院心血管内科住院的考虑冠心病无症状心肌缺血患者96例作为研究对象,均行DCG及MPI检查,同时以冠状动脉造影结果为金标准,即冠状动脉造影证实至少有1支冠状动脉局部狭窄≥50%,比较DCG、MPI和二者联合应用诊断冠心病无症状性心肌缺血的准确性、灵敏度及特异性。结果:MPI诊断的灵敏度及准确度均高于DCG,P<0.05;二者联合诊断的灵敏度、特异度均高于单独应用DCG或MPI,P<0.05。结论:DCG联合MPI均能实现冠心病无症状性心肌缺血诊断,但是将两种方式进行联合,其诊断效能更高,诊断结果更加精确,降低漏诊以及误诊率。Objective:To explore the diagnostic efficacy of dynamic electrocardiography combined with myocardial perfusion imaging in silent myocardial ischemia in coronary heart disease.Methods:96 patients with suspected coronary heart disease silent myocardial ischemia admitted in Tianjin Fourth Central hospital from January 2022 to January 2023 were enrolled in this study as the research subjects according to the entry criteria and exclusion criteria.All patients undergo DCG and MPI,based on the results of coronary angiography(CAG),coronary angiography confirms that at least one coronary artery has local stenosis≥50%,the accuracy,sensitivity,and specificity of DCG,MPI and the combination of two methods are compared.Results:The sensitivity and accuracy of MPI are significantly higher than that DCG(P<0.05).The sensitivity and specificity of the combined examination are more significantly than those of DCG or MPI(P<0.05).Conclusion:DCG and MPI can be used to diagnose silent myocardial ischemia in coronary heart disease,but the combination of two methods has higher diagnostic efficacy,more accurate diagnostic results,and less missed diagnosis and misdiagnosis.
