Aim: To determine the body mass index (BMI) and its various associations among patients who presented with ST segment elevation myocardial infarction (STEMI) at tertiary care hospital, Gujranwala, Pakistan Methods: In this cross-sectional study, acute STEMI patients were categorized according to their BMI (Kg/m2).Independent sample T test was used to compare the mean values of quantitative variables in two groups of a qualitative variable. The p value was taken statistically significant if < 0.05 Results: Amongst 668 patients, 1.2% were underweight, 34.1% normal weight, 43% overweight, 16.9% class 1 obese, 3.6% severe obese, and 1.2% morbid obese. The mean BMI of patients was 27.06±4.16 Kg/m2. The mean BMI was significantly higher among patients who had coexisting diabetes mellitus (p<0.001), hypertension (p<0.001), inferior wall MI (p<0.001), right ventricular involvement (p=0.002) and who died during hospitalization (p<0.001). The mean BMI was significantly lower among group of patients whose ST segment got settled >50% at first post-admission day (p=0.013). As compared to non-obese patients, obese patients reached hospital earlier (p=0.006), had more baseline maximum ST segment elevation (p=0.027) and significantly lower pulse rate per minute at 1st post-admission day (p=0.019) Conclusion: Majority patients who suffered STEMI were overweight. The higher BMI was predictive of inferior wall MI, right ventricular involvement, and death outcome of hospitalization while the lower BMI was significantly associated with more than 50% ST segment settlement at first post-admission day. As compared to non-obese patients, obese patients reached hospital earlier, perhaps being feared. They had more baseline maximum ST segment elevation and significantly lower pulse rate per minute at 1st post-admission day.
