Objectives - The aim of this study was comparing the prevalence of ST elevation myocardial infarction in 1997 with the prevalence in 2010 considering age groups in the hospitals of Ahvaz Jundishapur University of Medical Sciences.
Methods - We considered the patients admitted with acute coronary syndrome at hospitals of Ahvaz Jundishapur University of Medical Sciences and all the patients with ST elevation myocardial infarction were included. We categorized the patients into six groups according their ages.
Results - 400 patients in 1997 and 243 patients in 2010 were included in this study. The prevalence of myocardial infarction has increased in patients younger than 35 years. There were no significant changes in the group of 35-45 years and group of 65-75 years. The most important changes in age distribution of myocardial infarction during 2010 were prevalence increasing in age group of 46-55 years and decreasing in age group of 56-65 years. During 1997, 17% of patients were patients older than 75 years while 27% of patients were older than 75 years in 2010.
