摘要：Introduction: Myocardial infarction (MI) with 25- 30% mortality rate is one of the most common causes of death in most countries. According to recent data, MI is an increasing event in Iran. The aims of this study were to determine the 1-year survival rate and its correlates with MI among patients. Methods: This nonconcurrent cohort study was done on 113 patients with first acute MI who had been admitted in Imam Hossein hospital during the year 2004. Kaplan-Maier product limit and log rank test for survival analysis were used. Results: From 113 patients studied, there were 73(64.6%) males and their mean age was 63.9±13.1 (range 16-89). According to of the past history of these patients relived that 23.9% had been smokers. The most frequent risk factors were hypertensions (53.1%), history of previous ischemic heart disease (35.4%), diabetes mellitus (24.8%) and heart block (6.2%). Thirty six (31.9%) of them died in first one-year after admission. The 1-year survival rate was 69 percent. Significant predictors of 1-year survival in our study were administration of streptokinase and use of ß-blockers after discharge. Conclusion: We concluded that mortality in first year after MI has been significantly reduced because of therapies including thrombolysis and ß-blockers.
