Introduction. The European System for Cardiac Operative Risk Evaluation
(EuroSCORE) was developed in order to predict operative risk in cardiac
surgery and to assess the quality of the cardio-surgical care. Introduction
of the uniform terminology in result evaluation process leads to the
significant improvement in measuring and evaluation of surgical treatment
quality. Objective. The aim of the study was to evaluate our results in
isolated coronary surgery using the EuroSCORE. Methods. The study was done
respectively by analyzing predicted mortality according to the EuroSCORE
model and observed operative risk in 4,675 coronary patients operated at our
Clinic during the period 2001-2008. For statistical analyses, the Pearson,
Chisquare and ANOVA tests were used. Results. The total postoperative
mortality predicted by the EuroSCORE was 2.9±2.25, while the observed one was
2.2%. When the scoring system and observed results were compared over the
years, a considerably lower observed mortality was found during the last 4
years. Overall average number of distal anastomoses was 2.62±0.84. During the
period 2004-2008, the average number of coronary anastomoses increased over
the years reaching the value of 2.77±0.88. The difference is at the level of
statistical significance with the trend of further increase. Percentage of
the patients with single or double graft myocardial revascularization
decreases, while the number of the patients with triple or more bypasses
increases. Conclusion. During the last years, the results in isolated
coronary surgery have considerably improved. The EuroSCORE overestimates
operative risk. In order to improve its predictive value, the model should be
recalibrated.
