title: Abdominal circumference as a predictor of 30-day outcome in acute coronary syndrome.
abstract: BACKGROUND
  Abdominal circumference (WC) is the measure that correlates most closely with the risk factors and death from cardiovascular disease. However, the impact of obesity on the prognosis of patients with cardiovascular disease remains controversial and requires further clarification.
  
  
  OBJECTIVE
  To evaluate WA as a predictor of 30-day outcome in patients who were hospitalized with acute coronary syndrome (ACS), in a referral hospital for the treatment of cardiovascular diseases.
  
  
  METHODS
  Contemporary cohort 267 patients who were hospitalized for ACS and who were followed for 30 days after discharge, taking into account the major cardiovascular events - MACE - (death, reinfarction, rehospitalization for coronary artery bypass grafting procedures). In the first 24 hours of admission, patients answered a questionnaire and were subsequently measured for WC. The statistical analysis was performed with SPSS 17.0, using the chi-square test for categorical variables and Student t test for numerical variables, with significance level of p < 0.05. The variables that had p < 0.10 in the bivariate analysis were included in a logistic regression model to evaluate the WC role as an independent predictor of MACE.
  
  
  RESULTS
  After multivariate analysis, only the female gender (OR = 8.86; 95% CI: 4.55-17. 10, p < 0.00), hypertension (OR = 2.06; 95% CI: 1.10-3.87; p = 0.02) and family history of ischemic heart disease (OR = 2.10; 95% CI: 1.17-3.74; p = 0.01) remained associated with the MACE.
  
  
  CONCLUSIONS
  In our study, the modified AC was not associated with increased incidence of MACE over the 30 days of follow-up.
