The aim of the present study is to validate the applicability of EuroSCOREas a preoperative predictive scoring system of mortality and morbidity for Egyptian patients undergoing coronary artery bypass grafting surgery. This can help to identify the preoperative risk factors that can precipitate the incidence of several postoperative complications. Indeed, this valuable information can provide the surgical team with additional information to evaluate the quality of care of Egyptian patients as well as achieving the desired improvement of medical service.
