OBJECTIVE: To compare the Cleveland Clinical Score and EuroSCORE when evaluating patients submitted to CABGS electively in Rio Grande do Sul. METHODS: Cohort study with 202 patients submitted to CABGS between January 2006 and March 2007. Surgical risks were categorized by the Cleveland Clinic and EuroSCORE as low, medium and high risks. The incidence of deaths was measured in a 60 days interval. RESULTS: The average age of patients was 62±10 years and 134(66%) were men. A correlation was observed between both scores to classify patients at different levels of risk. Patients were categorized using the Cleveland Clinic and EuroSCORE respectively: 142(70.3%) and 155(76.7%) as low, 56(27.7%) and 43(21,3) as medium and 4(2%) and 4(2%) as high risks, with a Kaplan correlation coefficient of 0.432; p0.001. In the first sixty days after surgery, 13(6.4%) patients had died. A correlation between the higher incidences of death with increased category of risk was observed in the Cleveland Clinic and EuroSCORE. Deaths occurred respectively in the Cleveland and EuroSCORE: 6(4.4%) and 7(4.5%) in the low; 5(8.9%) and 5(11.6%) in the medium and 2(50%) 3 1(25%) in the high risks. Noted sensitivity in surgical mortality forecast was of 72.5% and 66.5% Cleveland and EuroSCORE respectively. CONCLUSION: The Cleveland Clinic and EuroSCORE risk scores have proven effective to evaluate risk of death in patients electively submitted to CABGS.
