摘要：

【摘要】 目的  分析近3年老年急性心肌梗死(AMI)发病是否具有时间变异性。方法  回顾性分析我院2009—2012年心脏科老年AMI入院病例908例。分别对入院例次逐日进行统计,结合患者一般临床资料分析老年AMI发病是否具有年、季节、月、昼夜变异性及"星期几"效应。结果  老年AMI发病逐年增加(P<0.01)。季节发病高峰为冬季,夏季为发病低谷。其中1月发病最高,6月发病最低。在有冠心病病史、心电图表现为ST段抬高及入院时心功能分级较差的患者中,AMI发病具有季节性差异(P<0.05)。AMI发病还具有昼夜变化规律(P<0.01),其中上午发病率最高,为(82.75±14.57)例次/月。结论  研究时段内AMI发病呈逐年上升趋势,且具有季节、月、昼夜的变化规律,应据此制定相应防治措施。

Abstract: Abstract   Objective   The purpose of this study was to determine whether a time variation could be observed in the occurance of acute myocardial infarction (AMI) in older patients in nearly three years. Methods    A retrospective analysis of patients diagnosed with AMI between 2009 and 2012 in the department of Cardiology of The Second Hospital of Tianjin Medical University (n=908 patients) was carried out. We calculated the number of AMI cases day by day. Combined with the general clinical data ,we analysis that whether a seasonal or monthly or weekly variation could be observed in the occurance of AMI in the elderly .Results    The occurance of AMI in older people increases year by year（p＜0.01）.A peak period of the incidence of AMI was recorded during winter, while minimum number of events were found during summer. Significant difference was observed between the number of events each season (p＜0.01).And the monthly occurrence of AMI was highest in January and lowest in June (p＜0.05). But the variation was only found in the patients which had coronary heart disease history or ST segment elevated in ECG or had poor heart function (P＜0.05). The cicadian rhythm of AMI morbidity was found, and the rhythm has no relation with seasons and months (p＜0.01) . The time peak period of AMI morbidity was found in the morning. Conclusion   Results of our study reveal that the incidence of AMI is on rise year by year and shows a characteristic rhythm with respect to seasons and months .Based on the results ,we can formulate prevention measures.
