比较十二导联动态心电图与冠脉造影检查在冠心病心肌缺血发作患者诊断中的临床意义

Clinical Significance of 12 Lead Dynamic Electrocardiogram and Coronary Angiography in the Diagnosis of Coronary Heart Disease with Myocardial Ischemic Attack

目的探究十二导联动态心电图与冠脉造影检查在冠心病心肌缺血发作患者诊断中的临床意义。方法选取安阳市人民医院2020年2月~2022年2月期间接诊的126例疑似冠心病患者开展研究,进行临床检查,对比诊断效果。结果经冠脉造影检查,心肌缺血发作比例88.89%;常规心电图检查阳性、阴性检出分别为70、56,12导Holter阳性、阴性检出分别为107、19,相较于前者,后者的敏感度(93.75%)、诊断符合率(92.86%)更佳,P<0.05;12导Holter诊断心肌缺血的平均发作频次、压低幅度较常规心电图检查高,ST段压低持续时间长于常规心电图(P<0.05)。结论对于冠心病心肌缺血病人,12导Holter和冠状动脉造影检查有着相一致的诊断效果,可确定心肌缺程度,以进行针对性救治。

Objective To explore the clinical significance of 12-lead dynamic electrocardiogram and coronary angiography in the diagnosis of myocardial ischemic attack patients with coronary heart disease.Methods A total of 126 suspected coronary heart disease patients admitted to Anyang People's Hospital from February 2020 to February 2022 were studied,and clinical examination was carried out to compare the diagnostic effect.Results:The proportion of myocardial ischemia attack by coronary angiography was 88.89%.The positive and negative detections of 12-lead Holter were 70,56 and 107,19 respectively.Compared with the former,the latter showed better sensitivity(93.75%)and diagnosis coincidence rate(92.86%),P<0.05.The average attack frequency and depression amplitude of 12-channel Holter in the diagnosis of myocardial ischemia were higher than that of conventional ECG,and the duration of ST-segment depression was longer than that of conventional ECG(P<0.05).Conclusion 12-channel Holter and coronary angiography have the same diagnostic effect for myocardial ischemia in patients with coronary heart disease,which can determine the degree of myocardial deficiency.For targeted treatment.
