【摘要】：目的研究T波峰末-间期老年心肌梗死患者跨壁复极离散度增大与室性心律失常、梗死程度及冠脉事件发生的关系,为老年心肌梗死预后评估提供指导意见。方法选取该院心内科老年急性心肌梗死(AMI)患者120例作为研究对象,其中男73例,女47例,平均年龄(62.37±11.34)岁。另选取其他心脏疾病的老年患者76例作为对照组,其中男42例,女34例,平均年龄(59.56±12.64)岁。分析不同分组患者T波峰末-间期及离散度和校正心率后T波峰末-间期及离散度。结果入院时对照组与AMI组间、AMI组内急性期患者与恢复期患者的T波峰末-间期、离散度及校正心率后T波峰末-间期、离散度方面比较,差异具有统计学意义(P0.01);AMI组不同室性心律失常患者校正心率前后T波峰末-间期、离散度比较,差异具有统计学意义(P0.01);AMI组前间壁、前壁、下壁、高侧壁与多支梗死患者之间的校正心率前后T波峰末-间期、离散度比较,差异具有统计学意义(P0.01);校正心率后不同T波峰末-间期患者死亡及入院时冠心病事件发生情况比较,差异具有统计学意义(P0.01)。结论 T波峰末-间期与恶性心律失常发生关系密切,对AMI老年患者的近期预后具有重要的预测价值。
[Abstract]:Objective to study the relationship between the increase of transmural repolarization dispersion and ventricular arrhythmia, infarction degree and coronary events in elderly patients with myocardial infarction at the end of T wave peak to interval, so as to provide guidance for the prognosis evaluation of myocardial infarction in the elderly. Methods 120 elderly patients with acute myocardial infarction (AMI) in Department of Cardiology were selected as subjects, including 73 males and 47 females, with an average age of (62.37 卤11.34) years. In addition, 76 elderly patients with other heart diseases were selected as the control group, including 42 males and 34 females, with an average age of (59.56 卤12.64) years. The end-to-peak interval and dispersion of T wave and the end-to-peak interval and dispersion of T wave after heart rate correction in different groups were analyzed. Results there were significant differences in T wave end-to-peak interval, dispersion degree and T wave end-to-peak interval and dispersion after corrected heart rate between control group and AMI group, AMI group and convalescent patients at admission (P 0.01). There was significant difference in T wave end-to-peak interval and dispersion before and after heart rate correction in AMI group (P 0.01). There were significant differences in T wave end-to-peak interval and dispersion between anterior interwall, anterior wall, inferior wall, high lateral wall and multi-vessel infarction patients before and after corrected heart rate in AMI group (P 0.01). After heart rate correction, there was significant difference between the death of patients at the end of peak and interval of T wave and the occurrence of coronary heart disease events on admission (P 0.01). Conclusion the end-to-end interval of T wave is closely related to the occurrence of malignant tachyarrhythmia, which is of great value in predicting the short-term prognosis of elderly patients with AMI.
