摘要
目的分析同步12导联动态心电图(dynamic electrocardiogram,DCG)对老年冠心病心肌缺血的诊断价值。方法采用回顾性研究,收集2023年8月~2024年12月于阜阳市第二人民医院就诊的80例老年冠心病患者的临床资料,患者均接受同步12导联DCG及冠状动脉造影检查。根据冠状动脉造影检查结果分为心肌缺血组(36例)与非心肌缺血组(44例),比较两组患者同步12导联DCG参数及相关资料差异,重点分析同步12导联DCG参数对老年冠心病心肌缺血的诊断价值。结果经冠状动脉造影检查,80例老年冠心病患者中有36例患者检出心肌缺血,检出率为45.00%。心肌缺血组患者同步12导联DCG参数(ST段压低持续时间、ST段压低振幅、P波离散度、T波峰-末间期)均高于非心肌缺血组(t=6.054、5.564、3.156、3.504,P<0.05)。绘制受试者工作特征(ROC)曲线,结果显示,ST段压低持续时间、ST段压低振幅、P波离散度、T波峰-末间期单项及联合诊断老年冠心病心肌缺血的曲线下面积(AUC)均>0.7,均具有一定诊断价值,且联合诊断价值高于各单项诊断(Z=2.270、2.078、3.893、3.841,P<0.05)。结论同步12导联DCG对诊断老年冠心病心肌缺血具有一定的价值,可为临床诊治提供重要的参考信息。
Objective To evaluate the diagnostic value of synchronous 12 lead dynamic electrocardiogram(DCG)for myocardial ischemia in elderly patients with coronary heart disease.Methods Clinical data of 80 elderly patients with coronary heart disease who visited the hospital from August 2023 to December 2024 were collected.All patients underwent synchronous 12 lead DCG and coronary angiography examinations.According to the results of coronary angiography examination,patients were divided into myocardial ischemia group and non-myocardial ischemia group.The differences in synchronous 12 lead DCG parameters and related data between myocardial ischemia and non-myocardial ischemia patients were compared,with a focus on analyzing the diagnostic value of synchronous 12 lead DCG parameters for myocardial ischemia in elderly coronary heart disease.Results Through coronary angiography examination,myocardial ischemia was detected in 36 of 80 elderly patients with coronary heart disease,with a detection rate of 45.00%.The synchronous 12 lead DCG parameters(duration of ST segment depression,amplitude of ST segment depression,P-wave dispersion,and T-peak to terminal interval)in the myocardial ischemia group were higher than those in the non-myocardial ischemia group(t=6.054、5.564、3.156、3.504,P<0.05).Receiver operating characteristic(ROC)curve was drawn for the subjects,and the results showed that the duration of ST segment depression,amplitude of ST segment depression,P-wave dispersion,and the area under the curve(AUC)of single and combined diagnosis of myocardial ischemia in elderly coronary heart disease were all greater than 0.7,indicating certain diagnostic value.Moreover,the combined diagnostic value was higher than the single diagnostic value of the above indicators(Z=2.270、2.078、3.893、3.841,P<0.05).Conclusion Synchronous 12 lead DCG has certain value in diagnosing myocardial ischemia in elderly coronary heart disease and can provide important reference information for clinical diagnosis and treatment.
