According to the types of myocardial infarction, Acute anterior wall MI was in 25.0%, Acute inferior MI was in 20.0%, EXT ANT WALL MI was in 16.0% and Acute inferior +RV MI was in 15.0% of patients. Elevated age in 70.0% and male gender in 69% of cases were found to be most common non-modifiable risk factors, while frequently seen Modifiable risk factors were smoking, type II diabetes, hypercholesteremia, hypertension, and physical activities.

Conclusion: It was observed that elevated age, male gender, smoking, diabetes and hypertension are frequent risk factors for ST elevation myocardial infarction.
