Comparison between Logistic EuroSCORE and EuroSCORE II: the ability to foresee in-hospital mortality in aged patients undergoing aortic valve replacement

摘要

Our study compares the EuroSCORE II (ESII) to the Logistic-EuroSCORE (LogES) concerning their ability to identify high mortality risk patients with aortic valve disease. 187 patients, 75+ years, who underwent isolated aortic valve replacement (AVR; n=98) or combined AVR and coronary surgery (AVR+CABG; n=89) were included. The analysis of the scores was made with the receiver operating characteristic curve (ROC), the area under the resulting curve (AUC) and the Hosmer-Lemeshow test. In every subgroup, ESII underestimated mortality risk, whereas LogES overestimated it. The model calibration was satisfying with both scores. The AUC for ESII was higher than AUC for LogES in every group. In conclusion, ESII slightly improves the LogES in elderly patients undergoing AVR. A cut-off value of 5.75 might be considered in order to identify high-risk patients.
