中老年人群中异常心电图的检出

Analysis of abnormal electrocardiography in a cohort of middle-aged and elderly people

目的探讨中老年人群心电图异常的相关因素。方法对1926例教职工体检的异常心电图发生率及危险因素进行分析。结果心电图异常检出率32.66%,以ST-T改变检出率最高,占62.80%,女性高于男性,心电图异常改变随年龄呈逐渐增加趋势,年龄分段比较,差异有统计学意义(p<0.05)。异常心电图人群中总胆固醇(TC)升高率49.92%,甘油三酯(TG)升高率36.41%,低密度脂蛋白(LDL-C)升高率50.24%,空腹血糖(FPG)升高率19.40%,高血压病25.44%,脂肪肝16.53%,较正常心电图人群比较,差异有统计学意义(p<0.05)。结论心电图异常改变与年龄、血脂异常、高血糖、高血压、脂肪肝密切相关。对上述多重危险因素进行强化干预很有必要。

Objective To study the electrocardiography（ECG） profile in middle-aged people in university and the clinical relevance.Methods ECG and blood biological analysis were performed in 1926 people working in Central University for Nationalities.Results Abnormal ECG was found in 32.66% of the population.The most common abnormality was the elevation of ST-T segment（62.80%）.This abnormality was seen more in female than in male.It also showed that the frequency of abnormal ECG was increased with age.In population with abnormal ECG,49.92% had increased blood cholesterol level.36.41% had increased triglycerin level.52.24% had increased low-density lipoprotein level.19.40% had increased blood glucose level.Hypertension Fatty liver were found in 25.44% and 16.53% of population respectively.All these abnormalities were found significantly higher than those with normal ECG（p0.05）.Conclusion Abnormal ECG was strongly associated with high blood pressure,elevated blood lipid level,high blood glucose level and fatty liver.Early intervention is necessary to prevent these people from developing heart diseases.
