Introduction :Acute myocardial infarction (AMI) is the most common cause of death in many countries, and also one of the common causes of death in Iran. As the death rate due to AMI is not clear and the survival rate of these patients had not yet been studied in the city of Yazd, this study was undertaken. Methods and materials : This was a survival study performed in Yazd between the years 2000 and 2002. 210 patients with definite AMI (according to clinical findings, ECG and enzyme criteria) were enrolled in this study (case series). They were admitted to Shahid Rahnemoon Hospital of Yazd (A general hospital). Results : The population under study included 161 males with mean age of 5914 years and 59 females with mean age of 6610 years. Frequency of hypertension, diabetes mellitus, hypercholestrolemia, hypertriglyceridemia and smoking was 27%, 22%, 20%, 22% and 32%, respectively. All risk factors except smoking were more common in females than men. 83.3% of infarctions were Q-wave infarctions, 16.7% non- Q-wave infarctions. 53% inferior wall and 40% were anterior wall infarctions. Infusion of streptokinase was done for 62% of patients. Mean ejection fraction of left vantricle was 48% in males and 45% in females. In-hospital mortality rate was 12.4% and higher in patients older than 70 years, diabetics, and anterior wall infarction patients. It had no correlation with sex. Surprisingly, smoking was accompanied with a very low in-hospital mortality rate. Conclution : One – year mortality rate of the patients in this study was 16.7% . It was higher in females, diabetics, anterior wall infarction patients and those with an ejection fraction less than 45%. The one year mortality rate in smokers was comparitively lower than non smokers in this study.
