摘　　要：目的分析平板运动试验与12导联动态心电图联合检查用于冠心病的诊断价值。方法选择本院2023年6月至2024年5月110例疑似冠心病患者为研究对象,所有患者均行平板运动试验及12导联动态心电图检查,以冠状动脉造影检查结果为“金标准”,比较2种方式单独检查及联合检查冠心病的诊断效能。结果“金标准”诊断结果显示,110例疑似患者中,阳性85例,阴性25例;平板运动试验显示,阳性89例,阴性21例;12导联动态心电图显示,阳性87例,阴性23例;二者联合检查显示,阳性84例,阴性26例;二者联合检查诊断冠心病的特异度96.00%、准确度97.27%、阳性预测值98.81%高于平板运动实验64.00%、87.27%、89.89%,高于12导联动态心电图72.00%、80.00%、91.95%(P<0.05);二者联合检查诊断冠心病误诊率4.00%低于平板运动实验36.00%,低于12导联动态心电图28.00%(P<0.05);冠状动脉造影结果显示,85例冠心病患者中单支病变20例,多支病变65例;平板运动实验、12导联动态心电图多支病变检出率98.5%、96.9%高于单支病变检出率80.0%、85.0%(P<0.05)。结论平板运动试验与12导联动态心电图联合检查诊断冠心病的价值高于单一检查,二者对冠心病的检出率随血管病变支数增加而增加。Objective To analyze the diagnostic value of treadmill exercise tests and 12-lead dynamic electrocardiogram in the diagnosis of coronary heart disease.Methods One hundred and ten patients with suspected coronary artery disease were selected from June 2023 to May 2024,all of them underwent treadmill exercise testsand 12-lead dynamic electrocardiogram,and the results of coronary angiography were used as the"gold standard"to compare the diagnostic efficacy of coronary artery disease between the two modes of examination alone and in combination.Results The diagnostic results of the"gold standard"showed that among 110 suspected patients,85 cases were positive,and 25 cases were negative;the treadmill exercise tests showed that 89 cases were positive,and 21 cases were negative,the 12-lead dynamic electrocardiogram showed that 87 cases were positive,and 23 cases of negative,the combined examination of the two showed 84 cases of positive and 26 cases of negative the specificity of the combined examination of the two for the diagnosis of coronary artery disease was 96.00%,the accuracy was 97.27%,and the predictive value of positivity was 98.81%higher than that of the treadmill exercise tests test of 64.00%,87.27%,89.89%,higher than 12-lead dynamic electrocardiogram 72.00%,80.00%,91.95%(P<0.05);the misdiagnosis rate of the two combined examinations for the diagnosis of coronary artery disease was 4.00%,lower than that of treadmill exercise tests 36.00%,lower than that of 12-lead dynamic electrocardiogram 28.00%(P<0.05);the results of coronary arteriogram showed that 85 cases of coronary artery disease.Coronary angiography results showed that among 85 cases of coronary artery disease,there were 20 cases of single-branch lesions and 65 cases of multi-branch lesions;the detection rate of multi-branch lesions of treadmill exercise tests and 12-lead ambulatory electrocardiogram was higher than the detection rate of single-branch lesions of 98.5%and 96.9%,which was higher than the detection rate of single-branch lesions of 80.0%a
