Prognostic models have been adopted in medical guidelines and are now widely used to assess risk and guide therapy.We applied STS scoring system to patients undergoing CABG to evaluate their predictive performance of early mortality and morbidities . Methods: In the period between septemper 2018and june 2020, we evaluated 100 patients who underwent CABG at the Kasr AL Ainy hospitals. STS values were calculated for the patients who were fall in the isolated CABG model of the STS risk models using the STS calculator v2.9 available online 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: STS model showed good discriminationpower and good calibration in Hosmer and Lemeshow Test in predicting mortality ,morbidity, renal failure,neurological complications, DSW infection and long length of stay. Also it showed bad calibration in predicting prolonged ventilation. However, it could not be assessed for reoperation and short length of stay because there was no events.Conclusion: STS scoring system is well calibrated to be used in the studied population that was submitted to CABG procedures, being able to detect mortality and the majority of the investigated outcomes specialized John Malaty Fouad Abdelmesseh ; Supervied Magued Abdelmesseh Zikri , Waleed Gamal Eldin Abosenna , Ahmed Salah Eldin Fouad Thesis (Ph.D.) - Cairo University - Faculty of Medicine - Department of Cardiothoracic Sugery Issued also as CD Coronary Artery Bypass Graft (CABG) Percutaneous Coronary Intervention (PCI) Society of Thoracic Surgeons (STS) http://172.23.153.220/th.pdf http://172.23.153.220/th.pdf EG-GiCUC 201025 20250223032619.0 eng
