摘要
目的 分析12导联动态心电图联合CT血管造影对无症状心肌缺血的诊断价值.方法 纳入 2020 年6 月至 2022 年 5 月本院诊治的 88 例疑似无症状心肌缺血患者为研究对象,均行 12 导联动态心电图、CT血管造影及冠状动脉造影检查.比较冠状动脉造影阳性组和阴性组的12 导联动态心电图结果、CT血管造影结果;以冠状动脉造影诊断结果为"金标准",比较12 导联动态心电图、CT血管造影单独及联合检查对无症状心肌缺血的诊断价值;分析 12 导联动态心电图、CT血管造影单独及联合检查与冠状动脉造影诊断结果的一致性.结果 冠状动脉造影检出阳性58 例,阴性 30 例;阳性组的QT间期、QTc间期显著长于阴性组(P<0.05).阳性组的斑块数、总斑块体积、总斑块负荷、血管狭窄程度和重建指数均大于阴性组(P＜0.05).12导联动态心电图、CT血管造影联合检查对无症状心肌缺血的诊断准确度高于单独检查(P＜0.05).12导联动态心电图、CT血管造影联合检查与冠状动脉造影诊断一致性良好(Kappa=0.806).结论 12 导联动态心电图联合CT血管造影对无症状心肌缺血的诊断效果良好,具有重要应用价值.
Abstract
Objective To analyze the diagnostic value of 12-lead dynamic electrocardiogram combined with CT angiography in asymptomatic myocardial ischemia.Methods A total of 88 patients with suspected asymptomatic myocardial ischemia diagnosed and treated in our hospital from June 2020 to May 2022 were included as the study objects.All patients underwent 12-lead dynamic electrocardiogram,CT angiography and coronary angiography examination.The results of 12-lead dynamic electrocardiogram and CT angiography were compared between the positive and negative groups of coronary angiography;with diagnostic results of coronary angiography as the"gold standard",the diagnostic value of 12-lead dynamic electrocardiogram,CT angiography alone and combined examination for asymptomatic myocardial ischemia was compared;the consistency of 12-lead dynamic electrocardiogram,CT angiography alone and combined examination with coronary angiography were analyzed.Results A total of 58 cases were positive and 30 cases were negative detected by coronary angiography;the QT interval and QTc interval in the positive group were significantly longer than those in the negative group(P<0.05).The number of plaques,total plaque volume,total plaque load,degree of vascular stenosis and reconstruction index in the positive group were higher than those in the negative group(P<0.05).The accuracy of combined examination of 12-lead dynamic electrocardiogram and CT angiography in the diagnosis of asymptomatic myocardial ischemia was higher than that of single examination(P<0.05).The combined examination of 12-lead dynamic electrocardiogram and CT angiography had good consistency with coronary angiography(Kappa=0.806).Conclusion 12-lead dynamic electrocardiogram combined with CT angiography has a good effect in the diagnosis of asymptomatic myocardial ischemia,and has important application value.
