急性心肌梗死患者发病季节规律

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。

A analysis on epidemic characteristics of acute myocardial infarction

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 X2 test. Results The mean age of AMI patients was （6420±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 ob served 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.
