Outcomes of Euroscore I at Operated Patients in Our Clinic

Abstract

Introduction: The aim of the study was to evaluate the suitability of Euroscore I as a risk stratification system at operated patients in our clinic. Patients and Methods: In this study totally 520 patients who underwent open heart surgery between September 2006 and May 2008. 356 were men, 164 were women, mean age was 65.03 ± 13.08 years. EuroSCORE I system was used as a risk stratification system. If the patients have taken 2 point or less it was evaluated as low risk, 3-5 points wereevaluated as medium, 6 points or higher was evaluated as high risk. The calculated values for these three different group and happened mortality ratios was compared with estimated mortality ratios. Results: In the low risk group there was 267 patients and estimated mortality was 1.38 ± 0.04%, happened mortality was 1.49 ± 0.32%. In the medium risk group there was 185 patients and estimated mortality was 3.24 ± 0.83%, happened mortality was 3.78 ± 0.23%. In the high risk group 68 patients the estimated mortality was 7.96 ± 2.34%, happened mortalitiy was 8.82 ± 2.12%. Conclusion: EuroSCORE I as a risk stratification system is an objective and secure system that was used for risk determination of cardiac surgery.
