EuroSCORE or regional system for cardiac operative risk evaluation

Background During the last decade many authors find that European Systems for Cardiac Operative Risk Evaluation (EuroSCORE), additive and logistic models, overestimate risk in cardiac surgery. The new EuroSCORE II has been recently introduced as an update to previous versions. The aim of the study: to investigate the prognostic value and discriminatory power of the additive and logistic EuroSCORE, and the EuroSCORE II.
