Abstract

Background: Cardiovascular disease is the first cause of mortality and hospital admission in elderly patients. The purpose of this study was to determine the short-term survival rates of acute myocardial infarction among elderly patients by age and sex. Methods: This was cohort-hospital study based on hospital admission in a 10-years period, that contained all elderly patients with acute myocardial infarction (AMI) aged equivalent or more than 65 years in Isfahan and Najaf Abad, Iran. To determine and compare the mean age, we used t-test and for survival rate Kaplan-Meier method and log-rank test were used. Findings: The overall 28-day survival rate for patients aged 65 years and more was 85.5%, against a 86.7% rate for men and 83.5% for women (P < 0.001). Survival rate in the age groups of 65 to 74, 75 to 84 and 85 and more years were 88.7%, 81.3%, 75.6%, respectively, with statistically significant difference (P < 0.001). Conclusion: Short-term survival rates of acute myocardial infarction is lower in elderly women than men; and in two genders, with increasing age, the rate continuously decreases. So, paying attention to women, especially older, due to higher risk of death, could be effective in improving outcomes. © 2014, Isfahan University of Medical Sciences(IUMS). All rights reserved.
