The prevalence of Acute Myocardial Infarction (AMI) varies from region to region caused by seasonal climate changes and temperature variation. This study aimed to assess the relationship between changing meteorological conditions and incidence of AMI in Iran.
This retrospective prevalence study was based on medical records of the heart center of Mazandaran Province on all patients diagnosed with AMI in Mazandaran, northern Iran between 2013 and 2015. Patients' sex and the day, month, year and time of hospital admission were extracted from patients' records. Moreover, the meteorological reports were gathered.
A statistically significant difference was found between the distributions of AMI cases across 12 months of the year ( < 0.01). Fuzzy clustering analysis using 16 different climatic variables showed that March, April, and May were in the same cluster together. The other 9 months were in different clusters.
Significant increase in AMI was seen in March, April and May (cold to hot weather).
急性心肌梗死（AMI）的患病率因季节气候变化和温度差异而在不同地区有所不同。本研究旨在评估伊朗气象条件变化与AMI发病率之间的关系。
这项回顾性患病率研究基于伊朗北部马赞德兰省心脏中心2013年至2015年期间所有被诊断为AMI的患者的病历。从患者记录中提取患者的性别以及住院日期、月份、年份和时间。此外，收集了气象报告。
发现一年中12个月的AMI病例分布存在统计学显著差异（<0.01）。使用16个不同气候变量的模糊聚类分析表明，3月、4月和5月属于同一聚类。其他9个月属于不同聚类。
3月、4月和5月（天气从寒冷到炎热）的AMI显著增加。
