Objective: To compare the feasibility of the EuroSCORE and The Society of Thoracic Surgeons risk scoring systems for predicting the surgical mortality of isolated coronary artery bypass surgery patients. Methods: The risk scoring of 148 patients who were operated on between April 2005 and March 2009 was performed prospectively according to the EuroSCORE and STS risk scoring systems. The predicted and observed mortality rates according to each scoring system were compared. Results: Hospital mortality was 13.2% (24 patients). The predicted mortality rate according to EuroSCORE was 4.71±4.9%, whereas it was 1.17±1.35% for STS. There were no significant differences between predicted and observed mortality rates according to either scoring system. The area under the ROC curve was 0.712 for EuroSCORE and was 0.727 for STS. Conclusion: Both scoring systems were efficient for predicting mortality rates for our study. It is an advantage of STS that it also gives valuable information about morbidity but for our not found satisfactory. In conclusion new risks scores for our country’s population are needed.
