The Performance of the EuroSCORE and the Society of Thoracic Surgeons Mortality Risk Score: The Gender Factor.
The purpose of this study was to explore potential differences in the performance of the EuroSCORE and the STS mortality risk score in the prediction of operative mortality following cardiac surgery with special focus on the impact of gender. We retrospectively reviewed 3125 consecutive cases of coronary artery bypass surgery performed at our institution between 2001 and 2004. STS and EuroSCORE (logistic [E-log] and additive [E-add]) operative mortality risk scores were calculated for each patient and stratified by gender (female: n=692; male: n=2433). Mortality risk scores were compared between the STS and EuroSCORE using C-statistics and likelihood ratios (LR). Stratified by gender, the E-log and E-add correlated well with the STS (female: r=0.77, 0.78, P
