RESUMEN
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). CONCLUSION: Preoperative EuroSCORE score is weakly correlated with postoperative QoL score in patients post CABG.

OBJECTIVE: The quality of life (QOL) 5 years after coronary artery bypass grafting (CABG) was evaluated by NHP, SAQ and DASI questionnaires. METHODS: NHP, SAQ and DASI questionnaires were mailed to 287 patients who received CABG in our department between Jan 2001 and Jan 2002. The reliability and construct validity of the questionnaires and the influence factor of QOL were analyzed. RESULTS: Two hundred and seventy-three patients (95%) responded to the questionnaires. The reliability of three questionnaires about QOL was 0.81, 0.75 and 0.78, respectively. QOL at 5 years post CABG was significantly better in CCS I/II patients than CCS III/IV patients' according to SAQ. Exertional scale and disease perception scale according to SAQ, social isolation and physical abilities to NHP also significantly related to QOL 5 years post CABG. CONCLUSIONS: All 3 questionnaires had high reliability and statistical validity for evaluating QOL. CCS angina degree affect the quality of life in patients 5 years post CABG.
