Gp. Miralda et al., ASSESSMENT OF HEALTH-RELATED QUALITY-OF-L IFE 2 YEARS AFTER CORONARY-ARTERY BYPASS-SURGERY, Medicina Clinica, 108(12), 1997, pp. 446-451
BACKGROUND: The determinants of quality of lire after coronary artery
surgery in well defined health care populations are still incompletely
understood. The aim of the present study was to assess the health rel
ated quality of life associated with coronary artery bypass surgery as
performed in a tertiary public hospital, and also to investigate its
association with clinical variables. PATIENTS AND METHODS: All survivo
rs of a first coronary artery bypass grafting operation performed duri
ng a calendar year in a single center (100 patients) were included for
assessment two years after surgery, Assessment included a review of t
he clinical records, a structured clinical interview and the administr
ation of three questionnaires of perceived health (Nottingham Health P
rofile, Duke Activity Status Index and SF-36 Health Survey). RESULTS:
The mean scores of the administered questionnaires corresponded to a m
oderate overall impairment of perceived health, with wide individual v
ariations. Chronic stable postoperative angina pectoris (28% of patien
ts), worse clinical functional grade (either due to angina or to other
s causes), comorbidity (51% of patients) and female sex were significa
ntly associated with worse scores. CONCLUSIONS: in the study populatio
n, postoperative angina, impairment of the clinical functional grade (
due to angina or to other conditions), and female gender were the majo
r determinants of impaired health related quality of life after corona
ry artery bypass surgery. As such determinants are associated with ana
tomoclinical variables in the population undergoing coronary bypass su
rgery and also with perioperative variables, appropriate effectivity s
tudies appear to be indicated for the assessment of this surgical proc
edure.
