Background and objective: Acute myocardial infarction (AMI) is the most prevalent cause of mortality in the world today. Sometimes before an acute phase of AMI there are certain prodromal symptoms. Since there are some social and cultural differences in Iranian population, this study was deigned to investigate the prodromal symptoms in patients with AMI in city of Birjand. Methods: In this analytic-descriptive research, 165 patients with first AMI who were hospitalized in the CCU and cardiac ward of the Valiassr Hospital in Birjand from the 2006-2007 were studied. A valid questionnaire which was designed by expert cardiologists was used. The T-test and ANOVA were used for data analysis, and p<0.05 was considered as the significant level. Results: Among 165 subjects, there was 118 (71.5%) males and 102 patients (61.8%) had Anterior MI. 61 patients (37%) reported cardiac prodromal symptoms and 43 patients (26.1%) reported systemic prodromal symptoms. The most common cardiac prodromal symptom 2 days before AMI was chest pain in the right and left hemithorax (24.2%), and the most common systemic prodromal symptom was loss of appetite (12.7%). Women reported more cardiac (p=0.04) and systemic (p=0.00) prodromal symptoms than men. This difference was statistically significant (p <0.05). Conclusion: Careful attention to history and prodromal symptoms in patients with cardiac risk factors may be caused early diagnosis, efficient treatment plan and better prognosis of AMI in patients.
