Incremental value of anemia in cardiac surgical risk prediction with the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II model.

Background: Anemia is a risk factor for adverse events after cardiac operations. We evaluated the incremental value of preoperative anemia over the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II to predict hospital death after cardiac operations.

Methods: Data for 4,594 consecutive adults (1,548 women [33.
