title: Patient and spouse perceived quality of life five years after coronary artery bypass graft surgery.
abstract: Health-related quality of life (HRQoL) was examined in patients' and their respective spouses' perspectives five years after cardiac bypass surgery. Participants completed the Short-Form 36 (SF-36) which consists of eight domains and two component summary scores measuring physical and mental HRQoL (PCS and MCS respectively). Paired t tests were used to compare couples responses (n=56 pairs) with spouses recording higher (i.e. better scores) in the physical-related domains although differences were not significant. Statistically significant results were found between patients and spouses in emotional role, mental health, social functioning, energy/vitality and general health perceptions (p< 0.001). The PCS were very similar for both the patient and spouses sample (45.9 v. 45.8 respectively, p = .829) and the MCS was significantly higher in the patients compared to the spouses (54.8 v. 47.7, p < .001). The results demonstrated that spouses could accurately report the physical aspects of HRQoL but not the mental health of their partner.
