- Abstract
Introduction: Location and type of MI are prognostic significant factors for predicting mortality after MI. This study was designed to prediction short and long-term survival rate in patient with MI in Iran. Methods: This is a Retrospective cohort study which its data were collected on 21181 cases of myocardial infarction recorded by the Iranian Myocardial Infarction Registry in 2013-2014. The follow up of these patients began after hospitalization, and Patients who died before received by the hospital were not included in the study .The last point was the time of death for all cause. In this study, Time-dependent event (survival) rates were estimated by Kaplan-Meier method and P values were determined by use of log-rank statistics. Continuous variables are presented as mean ± standard deviation (SD).Categorical variables were summarized as frequencies and percentages Results: This study evaluated 21181 patient with the first attack of MI. There were 15328 (72.37 %) men and 5853 (27.63 %) women. the most common symptoms were pain left arm(46.60 %), Sweating (40.37 %) and Dyspnea (32.07 %). During the first year after AMI, the most frequent complication was heart failure (7.90 %). The most common location of MI was acute transmural myocardial infarction of anterior wall (31.86 %). Overall, the 28 day, 6 month and 1 year survival rates were 0.95 (0.95-0.96), 0.90 (0.90-0.91) and 0.88(0.88-0.89). Conclusion: One year after MI, 2479(11.72 %) patient had died and 18681 (88.28 %) had survived (right-censored). Hypertension, diabetes and chronic heart disease was most common risk factors. The short and long-term survival rates in male were higher than female. Short and long-term survival rates were the lowest in patient with acute transmural myocardial infarction of anterior wall, inferior wall and other sites and patient with acute transmural myocardial infarction of inferior wall had the highest short and long-term survival rate.
