1 023例急性心肌梗死患者发病时间特点分析

目的探讨急性心肌梗死患者发病的时间特点。方法收集首都医科大学宣武医院1994年～2004年共1023例初发急性ST段抬高心肌梗死患者资料,统计患者月、周和昼夜发病的规律,计算各段发病人数及百分比,统计分析采用一致性χ2检验。结果1)夏季发病人数明显少于其他季节,其中6月份最低(P<0.05)。2)周二、周五和周六为发病高峰,中青年组和老年组之间差异无统计学意义。3)24h中,0:00～1:00、6:00～7:00、9:00～10:00、13:00～14:00、17:00～18:00时的心肌梗死患者所占比例最高(P<0.05);24h内6:00～9:00、13:00～17:00和21:00～24:00为心肌梗死高发时段。结论心肌梗死的发病在时间上存在一定规律,与性别和年龄无关,是人体生理周期和环境变化的反映。

Characteristics of Onset Timing in 1023 Patients with ST Segment Elevation Myocardial Infarction

Objective To analyze characteristics of onset time in patients with ST segment elevation myocardial infarction.Methods One thousand and twenty-three patients with STEMI were divided into different groups according to the timing of day,week and year when AMI occurred.The number and percentage of patients were observed in various subgroups.Uniformity was tested by a chi square test.Results 1) Onset was less in summer than that in other seasons.It was minimal in June(P<0.05).2) Three peaks of onset of AMI were...
