title: Multicenter study of perioperative evaluation for noncardiac surgeries in Brazil (EMAPO).
abstract: BACKGROUND
  The accuracy of perioperative evaluation methods available is better than chance, but their performance is not ideal.
  
  
  OBJECTIVE
  To compare a new evaluation method (EMAPO) to the American College of Physicians method for determining the risk of cardiovascular complications in noncardiac surgeries and to look for new influencing variables.
  
  
  METHODS
  Evaluations through EMAPO and the American College of Physicians method were employed for 700 patients. Cardiac events and deaths were recorded, the risk variables related to the occurrence of complications were verified, and the models were compared by analyzing the areas under the receiver operating characteristic curves.
  
  
  RESULTS
  Mortality rate was 3.4%, and the incidence of cardiovascular complications was 5.3%. Renal failure (P = 0.01), major surgery (P = 0.004), and emergency surgery (P = 0.003) were independently related to the occurrence of cardiovascular complications. The two methods produced similar results.
  
  
  CONCLUSIONS
  EMAPO is as good as the American College of Physicians method in determining the risk of cardiovascular complications in noncardiac surgeries. New variables related to surgical risk were identified.
