[摘要] 目的 探讨急性心肌梗死(AMI)发病与时间、季节变化的关系。 方法 以我院近2年冠心病监护病房收治的AMI患者446例为研究对象，记录并计算1～12月中发病患者数及百分比，根据年龄分为<65岁组与≥65岁组，比较两组不同季节发病患者数及百分比。统计分析采用χ2检验。 结果 患者平均年龄(64.20±12.87)岁。男女之比为2.3∶1，男女患者发病的平均年龄分别是(60.87±12.85)岁与(71.80±9.19)岁。两组患者发病季节差异比较无统计学意义。 结论 心肌梗死的发病时间特征较以往有所变化，AMI发病与年龄相关，与季节无关。

[Abstract] Objective To investigate the incidence and seasonal variation of acute myocardial infarction (AMI). Methods The date of 446 patients with AMI were collected. These patients were divided into two groups according to age(< 65 years old and≥65 years old). The monthly and the seasonal variations were evaluated. Statistical analysis was conducted by χ2 test. Results The mean age of AMI patients was (64.20±12.87) years old. The ratio of male to female was 2.3：1. The male patients were younger than the females (60.87±12.85) and (71.80±9.19) years old， respectively. No significant differences were observed between 2 groups in incidence season. Conclusion Characteristics of the onset of myocardial infarction than in the past changes， AMI incidence with age—related， and the season was no significant difference.

急性心肌梗死(acute myocardial infarction，AMI)是严重威胁人类健康的常见疾病之一，其发病具有一定流行病学特征，既往研究资料多提示我国AMI发病有一定时间、季节分布特点，以寒冷季节多发，关注疾病的发病特点有利于发现发病规律，进而采取有效的防范措施。但随着经济建设的快速发展、人们生活水平的不断提高以及社会压力的增加 ......
