Direct comparison of EuroScore 2 and LES. The LES shows a wide numeric range. The cut-off value of 20% as recommended by actual guidelines is marked. Of the deceased patients in both subgroups, all but one exceeded this threshold and were preoperatively identified as high risk patients. The retrospective evaluation with the EuroScore 2 shows a poor correlation to its predecessor (τ = 0.524; p < 0.01). Only very few patients exceed a risk score of 10%.
