急性ST段抬高型心肌梗死发病时间节律特征的探讨

Acute ST-segment elevation acute myocardial infarction temporal rhythm characteristics

目的探讨急性ST段抬高型心肌梗死（STEMI）的发病时间规律及其机制,为STEMI防治提供依据。方法回顾性分析491例就诊于急诊科的急性ST段抬高型心肌梗死患者,以胸痛出现的时间为发病时间,统计患者发病的日、周和季时间分布。结果 STEMI患者一日内发病有两个高峰时段,依次为06：01-12：00和18：01-24：00,分别为137例占28%和130例占26.5%。STEMA患者一周内发病有两个高峰,周一80例占16.3%,周五82例占16.7%。STEMI患者一年内发病按季节分布以冬季最高,为140例占28.5%,发病数最低为夏季,为98例占20.0%。结论 STEMI发病具有时间节律特征,应依据其时间节律特征进行预防。

Objective To investigate the time of onset of acute ST-segment elevation myocardial infarction（STEMI） and its mechanism, provide the basis for prevention and treatment of STEMI.Methods The time of onset of 492 cases with STEMI was analyzed by mathematical statistics the peak time of onset in 24 hours,a week and a season were calculated.Results STEMI onset has two peak periods a day, 6：01 to 12：00 and 18：01 to 24： 00, respectively, 137 cases accounting for 28% and 130 cases accounted for 26.5%. There are two onset peaks in a week for patients.Monday 80 cases accounted for 16.3%, friday 82 cases accounted for 16.7%.STEMI onset patients a year according to the seasonal distribution in winter maximum, 140 cases accounted for 28.5%, the lowest incidence for the summer, 98 cases accounted for 20.0%.ConclusionSTEMI onset rhythm with a time characteristic, should be based on the characteristics of its time rhythm prevention.
