Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Medicine - Department of Cardiothoracic Surgery Summary: Objectives: This study was carried out to analyze patient data both in retrospective and prospective design to compare the european system for cardiac operative risk evaluation (Euro SCORE II) and society of thoracic surgeons (STS) risk models in Egyptian cardiac surgical patients. Methods: A computerized registry of all patients having cardiac surgical procedures at NASSER institute Hospital will be used to identify patients{u2019} data, a total of 1238 patients were evaluated. Euro SCORE II and STS values had been calculated. The area under a receiver operating characteristic (ROC) curve, was used to represent the discriminative power of the scoring system and The Hosmer-Lemeshow statistic was used to assess calibration. Results: In hospital observed mortality in our study was 21 (1.7 %). The area under curve (AUC) for STS in predicting mortality was 0.652, while AUC for euro SCORE II was 0.639. Both showed good calibration. And the AUC for STS in predicting morbidity was 0.589, While AUC for euro SCORE II was 0.603. STS showed good calibration. But unfortunately, Euro score II showed failed calibration P. value =0.004. Liver dysfunction prevalence was 8.2% (101 patients) with child-turcotte-pugh (CP) classes A, B and C was 61 (60.4 %), 39 (38.6%) and 1(1%) respectively. The in-hospital mortality of patients with CP class A, B or C was 0, 7.7 and 100%, respectively. And the incidence of morbidity of patients with CP class A, B or C was 36, 28.2 and 100%, respectively. We proved the significant relation between liver dysfunction and occurrence of morbidity P value 0.013, but we failed to prove this relation to mortality
