RESUMO
Nowadays, obesity is developing as an epidemy and it is one of major risk factors of coronary artery disease, therefore this study determinated the effect of obesity on age of occurrence of MI and It's mortality. In this prospective study we studied on 212 hospitalized patients because of MI in CCU[s] from May 2001 to October 2002 and they followed for one year, questionnaires for all patients were completed and data analyzed with SPSS ver.11.00.. 34.9% of patients were overweight and 16.5% were obese. Average BMI was 25.87 +/- 4.38. Obese patients were younger than overweight and normal weight patients significantly. [P=0.039] there was a linear relationship between BMI and age of occurrence of MI. [P=0.005]. Obesity and overweight status didn't affect on hospital and late [1 year] mortality. According to our results, obesity associated with premature occurrence of AMI because obesity accelerated coronary atherosclerosis but obesity didn't associate with increased incidence of inhopsital or one year mortality. Thus we suggest to long term follow up in later studies
