Excess weight and life expectancy after acute myocardial infarction: The obesity paradox reexamined.

ABSTRACT:

Background

An "obesity paradox" has been described in patients with acute myocardial infarction (AMI), whereby obese and overweight patients have a lower risk of short-term mortality after AMI than normal-weight patients. However, the long-term association of obesity with mortality after AMI remains unknown.

Methods

We used data from the Cooperative Cardiovascular Project, a prospective medical record study of Medicare beneficiaries hospitalized with AMI with 17 years of follow-up (N = 124,981), to evaluate the association of higher body mass index (BMI) with short- and long-term survival after AMI. Cox proportional hazards models were used to estimate life expectancy after AMI and the years of potential life lost or gained attributable to excess weight.
