据报道，急性心肌梗死（AMI）的发病与天气条件有关。本研究的目的是调查天气条件对急性心肌梗死发病的影响。我们的研究人群包括274例在2012年6月至2013年5月期间因AMI入院的大分AMI登记研究患者。我们把一年的365天分为四个季节：春天（3月、4月、5月）、夏天（6月、7月、8月）、秋天（9月、10月、11月）和冬天（12月、1月、2月）。我们将每一天分为AMI发病日（发病日）或AMI非发病日（非发病日）。最高温度、最低温度、平均湿度和平均气压的信息来自日本气象厅。夏季发病日气温和日内温差均明显低于非发病日。受试者操作特征分析显示，夏季发病前2d最高气温的曲线下面积最大（AUC= 0.72，p =0.0005）。我们的分析表明，在大分县，每个季节都存在影响AMI发病的特定天气条件。夏季发病与发病前2d最高气温有显著相关性。
The onset of acute myocardial infarction (AMI) has been reportedly related to weather conditions. The aim of this study was to investigate the impact of weather conditions on AMI onset. Our study population consisted of 274 patients enrolled in the Oita AMI Registry who were admitted with AMI between June 2012 and May 2013. We divided the 365days of the year into the four seasons: spring (March, April, May), summer (June, July, August), autumn (September, October, November), and winter (December, January, February). We classified each day as a day of onset of AMI (onset day) or a day of non-onset of AMI (non-onset day). Information on maximum temperature, minimum temperature, mean humidity, and mean atmospheric pressure was obtained from the Japan Meteorological Agency. In summer, the temperatures and intraday temperature differences were significantly lower on onset days than on non-onset days. Receiver operating characteristic analysis for predicting AMI onset in each season showed that the maximum temperature 2days before AMI onset in summer had the largest area under the curve (AUC=0.72, p=0.0005). Our analysis demonstrated that there exist specific weather conditions that influence AMI onset in each season in Oita prefecture. AMI onset in summer was particularly associated with the maximum temperature 2days before AMI onset.
