title: Validation of EuroSCORE for coronary artery bypass grafting at Siriraj Hospital.
abstract: OBJECTIVE
  To access the performance of the EuroSCORE when applied to CABG patients at Siriraj hospital.
  
  
  METHODS
  One thousand five hundred forty nine patients diagnosed with coronary artery disease (CAD) who underwent isolated CABG between January 2007 and December 2009 was prospectively studied.
  
  
  RESULTS
  The patients included 1,102 men and 447 women and had a mean age of 67 years old. The mean additive score in expired and survived groups were 9.65 +/- 5.14 and 3.87 +/- 3.06. In logistic, score were 25.43 +/- 26.31 and 4.88 +/- 7.88 respectively (p < 0.001). The best cut-off value of EuroSCORE for prediction of a death rate was 6 for additive score and 10 for logistic score. Area under the curve was 0.831 for the additive score and 0.823 for the logistic score. The observed overall mortality rate was 2.0% while the predict mortality was 5.27%. The difference between observed and predicted deaths was significant with additive score and logistic score (p < 0.001).
  
  
  CONCLUSIONS
  Our results suggest that EuroSCORE is not valid for CABG in Thai patient due to over prediction.
