EuroSCORE predicts immediate and late outcome after coronary artery bypass surgery.

Background: The European system for cardiac operative risk evaluation score (EuroSCORE) has been shown to be of value in identifying patients at high risk for adverse immediate postoperative outcome after adult cardiac surgery. The aim of the present study was to evaluate EuroSCORE in predicting the 12-year outcome of patients who underwent on-pump coronary artery bypass surgery (CABG).

Methods: We calculated the EuroSCORE in 917 patients who underwent CABG. The median follow-up was 11.7 years.

Results: Both additive and logistic EuroSCORE had an area under the receiver operating characteristic curve of 0.856 for prediction of 30-day postoperative death. Among 912 operative survivors, the 10-year survival rates according to quintiles of additive EuroSCORE were 87.9%, 83.9%, 85.2%, 76.0%, and 51.3% (p < 0.0001). The 10-year survival rates according to quintiles of logistic EuroSCORE were 87.9%, 85.4%, 86.5%, 76.9%, and 58.9% (p < 0.0001).

Conclusions: EuroSCORE is a relevant predictor of immediate and late outcome after on-pump CABG.
