Impact of body mass index on short-term outcome after acute myocardial infarction: does excess body weight have a paradoxical protective role?

Background: Obesity is a risk factor for acute myocardial infarction (AMI), due in part to obesity-related conditions. However, the relation between BMI (body mass index) and outcome in patients with AMI has not been completely clarified. The aim of our study was to assess the impact of BMI on short-term outcome after AMI.
