title: [Quality of life five years after coronary artery bypass grafting].
abstract: 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.
