健康体检人群行心电图与冠状动脉CTA筛查冠心病的对比分析
Comparison analysis of ECG and coronary CTA in diagnosis of coronary heart disease
目的 探讨健康体检人群行心电图与冠状动脉CTA筛查冠心病的对比分析。方法 选取2021-05在解放军总医院第三医学中心健康医学科参加体检的3293人为研究对象,剔除未接受冠脉CTA检查的97人,未行心电图检查的10人,入选3186人,对体检结果异常心电图及冠状动脉狭窄的判断进行分析。结果 3186人中通过冠状动脉狭窄判断结果,共检出冠心病237例;异常心电图表现:ST-T改变750例,心电轴左偏137例,左室高电压83例,完全性右束支传导阻滞42例,不完全性右束支传导阻滞41例。冠心病患者中ST-T改变33.3%,高于非冠心病组的22.8%,差异有统计学意义(χ2=13.642,P＜0.05)。结论 心电图操作简单方便,在大规模人群健康体检中对冠心病有提示作用,可配合动态心电图、心脏彩超等其他检查,进行冠心病筛查。
Objective To compare ECG and coronary CTA in the diagnosis of coronary heart disease among people of physical checkup.Methods A total of 3186 subjects were selected as the research objects from 3293 physical examinees in our health medical center in May 2021,excluding 97 subjects who did not receive coronary CTA and 10 subjects who did not implement ECG. Descriptive statistics and grouping chi square were used to analyze the physical examination Results.Results A total of 237 cases of coronary heart disease were found with the judgement of coronary stenosis. The abnormal electrocardiographic manifestations were as follows: 750 cases of ST-T segment change, 137 cases of left deviation of ECG axis, 83 cases of left ventricular high voltage, 42 cases of complete right bundle branch block and 41 cases of incomplete right bundle branch block. There was statistical difference in ECG between patients with coronary heart disease (33.3%)and patients without coronary heart disease (22.8%)(χ2=13.642,P＜0.05).Conclusions ECG which is simple and convenient can help to distinguish coronary heart disease in large-scale physical examination population with other check programs.
