Coronary artery diseases are regarded as the main cause of mortality in most countries. The present study aims at evaluating variations and studying its complications in Iranian patients within past 20 years.This cross-sectional analytical-descriptive study retrospectively evaluated the files of 600 patients with acute myocardial infarction during a 20-year period. Basic data and laboratory information, chemotherapies and intervention treatments of patients were registered in special forms and compared regarding the mentioned time intervals.There were 440 (73.3%) male and 160 (26.7%) female patients and mean age of the patients was 60.03 آ± 11.61 years. Mean duration of hospitalization (p < 0.001) and prevalence of smoking (p < 0.001) had significantly decreased in the past two decades. There was no meaningful difference when considering mortality rate (p = 0.533) and cardiac insufficiency (p = 0.403).The results indicate prominent improvement in the management process of patients suffering from acute myocardial infarction within the past 20 years.
