Smoking as a risk factor constitute 70.4%(164 pt.) and Diabetes mellitus 62.3% (43pt.) among males and females respectively. Anterior wall MI reports to be 62.20%(145 pt.) and 82.10%(55 pt.) among males and females followed by other types of STEMI. Conclusion: Smoking is identified as an independent risk factor that can lead to STEMI in young males while Diabetes Mellitus and hypertension identified as a risk factor for progression to STEMI in females. Among non-modifiable factors male sex, old adults and family history identified as factors that can lead to STEMI.
