Abstract |
|---|
302 patients were evaluated for the EuroSCORE risk and health-related quality of life (HRQoL) during 3 years after CABG as assessed by the 15D instrument. Both additive and logistic EuroSCORE correlated significantly with the 15D score at 6, 18 and 36 months. A clinically important increase 
0.03 in the 15D score was achieved by 50.6% of patients at 6 months, 40.0% at 18 months and 35.9% at 36 months. The rates were similar among patients with increasing EuroSCORE at 6 and 18 months, but tended to decrease at 36 months in the highest EuroSCORE group (EuroSCORE 0-2: 46.8%; 3-5: 34.8%; and 6-14: 33.3% respectively, P=0.13). Both additive (area under the receiver operating characteristic curve, AUC: 0.582, P=0.024) and logistic EuroSCORE (AUC: 0.575, P=0.039) were predictors of a significant increase of the 15D score. The best cut-off value of the additive EuroSCORE for prediction of a clinically important improvement of the 15D score during 3-year follow-up was 3, as 46.7% of patients with EuroSCORE 0-3 and 30.1% of patients with a score >3 (P=0.006) improved clinically. The present study showed that the EuroSCORE also predicts long-term HRQoL after CABG. Keywords: EuroSCORE; Myocardial revascularization; Quality of life
