[The role of European system for cardiac operative risk evaluation in the prediction of quality of life in patients after coronary artery bypass graft surgery].
OBJECTIVE
To assess the value of European system for cardiac operative risk evaluation (EuroSCORE) in predicting quality of life in patients post coronary artery bypass graft surgery (CABG).


METHODS
A total of 387 patients underwent CABG in our institute from December of 2002 to December of 2007 were assessed by EuroSCORE before operation. Health-related quality of life (QoL) was estimated postoperatively with Seattle angina questionnaire (SAQ), Nottingham healthy profile (NHP) and Duke activity status index (DASI) in order to evaluate the value of EuroSCORE for predicting quality of life in patients post CABG.


RESULTS
There were statistically significant but weak correlations between postoperative QoL score and preoperative EuroSCORE score (r: 0.010 - 0.276). Emotional and psychological experience subgroup analysis showed better predictive value of EuroSCORE score on postoperative QoL score in improved physical functioning subgroups (r > 0.2). Linear regression analysis showed that EuroSCORE score was significant but weakly (r(2) < 0.1) correlated with postoperative QoL score (P < 0.05).


CONCLUSIONS
Preoperative EuroSCORE score is weakly correlated with postoperative QoL score in patients post CABG.
