Acute myocardial infarction (AMI) is one of the main causes of morbidity and mortality in Brazil and worldwide. Seasonality and climate change seem to be associated with hospitalization for AMI.
to analyze the effect that seasonality and temperature have on the number of hospitalizations and deaths due to AMI, stratified by gender and age group, from 2009 to 2018 in a region of southern Brazil.
An Ecological study, composed of cases of hospitalizations and deaths by AMI in the Association of Municipalities of the Laguna Region (AMUREL), SC, Brazil. Data on AMI were collected by the Department of Informatics of the Unified Health System (DATASUS) and data on average monthly temperature (degrees Celsius) of the Laguna region (SC, Brazil) were provided by the National Institute of Meteorology (INMET). The data analysis was performed through linear regression and ANOVA test with Tukey post-hoc.
2947 hospitalizations were analyzed. The monthly average hospitalization per AMI was 24.6±8.1 cases (7.0±2.2/100,000 inhabitants) with a lethality of 14.4±6.8%. The results showed that there is no difference in AMI hospitalization between the months of the year, but showed a significant negative correlation between temperature and AMI hospitalizations (r=-0.219; P=0.022; β=-0.165). It was also shown that men and elderly had more cases of AMI hospitalization, but women and elderly had more lethality. When the lethality rate was analyzed during the study period, there was a significant negative correlation, indicating the reduction of AMI deaths with time.
There was an association between temperature reduction and AMI hospitalization, where each 6°C reduction in temperature was related to an increase of 1 hospitalization per AMI/100,000 inhabitants. It is hoped that the results may assist in the formulation of public environmental policies for the prevention of risk factors for AMI.
急性心肌梗死（AMI）是巴西乃至全球发病和死亡的主要原因之一。季节性和气候变化似乎与AMI住院治疗有关。
分析2009年至2018年巴西南部某地区季节性和温度对按性别和年龄组分层的AMI住院人数和死亡人数的影响。
一项生态学研究，由巴西圣卡塔琳娜州拉古纳地区市际协会（AMUREL）中AMI住院和死亡病例组成。AMI数据由统一卫生系统信息部（DATASUS）收集，巴西圣卡塔琳娜州拉古纳地区的月平均温度（摄氏度）数据由国家气象研究所（INMET）提供。数据分析通过线性回归和带有Tukey事后检验的方差分析进行。
分析了2947例住院病例。每例AMI的月平均住院人数为24.6±8.1例（7.0±2.2/10万居民），致死率为14.4±6.8%。结果表明，一年中各月份的AMI住院情况无差异，但温度与AMI住院人数之间存在显著负相关（r=-0.219；P=0.022；β=-0.165）。还表明，男性和老年人的AMI住院病例较多，但女性和老年人的致死率较高。在研究期间分析致死率时，存在显著负相关，表明AMI死亡人数随时间减少。
温度降低与AMI住院之间存在关联，温度每降低6°C，每10万居民中每例AMI的住院人数增加1例。希望这些结果有助于制定预防AMI危险因素的公共环境政策。
