Abstract

Introduction: Regarding the association between climate, seasons and myocardial
infarction, a cross-sectional study was carried out in Shiraz and Bandar Abbas in Iran.
Methods: All patients with diagnosis of acute myocardial infarction living in Shiraz and
Bandar Abbas were included in the study during 2011-2013. Demographic data were
extracted from the patients’ hospital records. Data were analyzed using descriptive
statistics, student’s t-test, and Chi-square test with SPSS software.
Results: A total of 2626 patients were admitted with acute myocardial infarction of which
1546 were from Shiraz and 1080 from Bandar Abbas. Admission rate due to myocardial
infarction was 0.12 in Shiraz and 0.24 in Bandar Abbas. In Shiraz, 35.2% of the patients
were female and in Bandar Abbas 34% Mean age of female patients was 65.68 years in
Shiraz and 62.46 in Bandar Abbas while mean age of male patients in Shiraz was 60.39
years and 57.22 years in Bandar Abbas. Difference in admissions rates in 4 seasons was
statistically significant in Shiraz, but not significant in Bandar Abbas. Seasonal variation of
myocardial infarction had no correlation with gender or age of the patients.
Conclusion: Incidence of myocardial infarction in Shiraz was half of the incidence rate in
Bandar Abbas. During summer in low altitude humid areas, extra healthcare should be
provided to high risk patients with coronary artery diseases, whereas this caution should
be taken in high altitude areas with cold winter to minimize incident of myocardial
infarction.
