Objective. Determination of trigger factors, incidence time, delay time and delaying factors in patients with acute myocardial infarction referred to selected military hospitals in Tehran city in year 2005. Material and Methods: This was a cross-sectional research which included 200 patients of acute myocardial infarction. These patients were gathered by convenience sampling method in military hospitals in Tehran city in 2005. Results. 73.5% of patients was male. Mean age was 56 years old. The most common risk factors were hypoactivity 79%, stress 66.5%, hyperlipidemia 43.5%, and smoking 42%. The most frequent week day of heart attack was Saturday (the first work day in Iran) (24%). The most frequent time of heart attack was 8 am – 12 Noon (32%). Trigger factors of disease in order of frequency were tension 40.5%, anger 31.5%, smoking 30.5%, waking up 29% and heavy activity 28.5%. After heart attack occurrence, the mean time of delay to take the patient to hospital was about 4 hours and 54 minutes and the most frequent reasons in order of frequency were self–treatment 51.5%, expectation of natural recovery 50% and unawareness 49%. Conclusion. Delaying factors reveals a need of comprehensive public training and providing enough transmission facilities for patients.
