[Body mass index in the prognosis of first myocardial infarction].
OBJECTIVE
The value of body mass index in the prognosis of patients with ischemic heart disease is not well defined. The objective of our study was to determine the association of body mass index with classic and emergent cardiovascular risk factors and with intra-hospital and 6-months mortality.


METHODS
We conducted a prospective, multicenter study with a 6-months follow-up. We included 1063 patients between the ages of 25-75 years old who were consecutively admitted to the hospital within the first 24 hours of the onset of symptoms between years 2001 and 2003. We determined demographic and anthropometric variables, as well as classic and emergent factors of risk, clinical variables and the treatment administered. We carried out a univariate and multivariate analysis.


RESULTS
The percentage of patients with overweight or obesity in this population was 73.56%. Overweight and obesity were associated with classical risk factors, except for smoking, and emergent risk factors. Body mass index was not associated with short-or mid-term prognosis.


CONCLUSIONS
Body mass index is not a useful anthropometric measure to determine the prognosis of patients after a first myocardial infarction.
