Objectives Beneficial effects of overweight and obesity on mortality after acute myocardial infarction (AMI) have been described as "Body Mass Index (BMI) paradox". However, the effects of BMI is still on debate. We analyzed the association between BMI and 1-year clinical outcomes after AMI. Methods Among 13,104 AMI patients registered in Korea Acute Myocardial Infarction Registry- National Institute of Health (KAMIR-NIH) between November 2011 and December 2015, 10,568 patients who eligible for this study were classified into 3 groups according to BMI (Group 1; < 22 kg/m2, 22 . Group 2 < 26 kg/m2, Group 3; . 26 kg/m2). The primary end point was all cause death at 1 year. Results Over the median follow-up of 12 months, the event of primary end point occurred more frequently in the Group 1 patients than in the Group 3 patients (primary endpoint: adjusted hazard ratio [aHR], 1.537; 95% confidence interval [CI] 1.177 to 2.007, p = 0.002). Especially, cardiac death played a major role in this effect (aHR, 1.548; 95% confidence interval [CI] 1.128 to 2.124, p = 0.007). Conclusions Higher BMI appeared to be good prognostic factor on 1-year all cause death after AMI. This result suggests that higher BMI or obesity might confer a protective advantage over the lifequality after AMI.
