目的:探讨急性心肌梗死(AMI)的发病时间规律及其机制,为AMI防治提供依据。方法:回顾性分析2856例ST段抬高型AMI患者,以胸痛出现的时间为发病时间,统计其发病的日、周和季时间分布,计算相应时段发病数及其占总发病数百分比,用X2检验对组间进行统计学检验。结果:日发病高峰出现在6:01~12:00,周发病高峰出现在周一,季发病高峰出现在冬季,并与各自相应的其他时段比较有显著性差异。结论:AMI发病具有日、周和季节律特征,应依据其时间节律特征进行预防。
Objective: To investigate the onset time and mechanism of acute myocardial infarction (AMI) and provide the basis for the prevention and treatment of AMI. Methods: A retrospective analysis of 2856 cases of ST-segment elevation AMI patients, the onset time of chest pain as the time of onset, statistics of the incidence of the week, week and seasonal distribution of the number of incidence of the corresponding period and the percentage of total incidence calculated by X2 test Statistical analysis of the groups. Results: The peak incidence of Japanese appeared at 6: 01 ~ 12: 00, the peak of the onset of the disease appeared on the Monday and the peak of the onset of the disease appeared in the winter, and compared with their corresponding other periods were significantly different. Conclusion: The onset of AMI has the characteristics of daily, weekly and seasonal rhythms, and should be prevented according to the characteristics of its time rhythm.
