- OBJECTIVE—To identify determinants of an inferior quality of life (QoL) five years after coronary artery bypass grafting (CABG). SETTING—University hospital. PARTICIPANTS—Patients from western Sweden who underwent CABG between 1988 and 1991. MAIN OUTCOME MEASURES—Questionnaires for evaluating QoL before CABG and five years after operation. Three different instruments were used: the Nottingham health profile (NHP), the psychological general wellbeing index (PGWI), and the physical activity score (PAS). RESULTS—2121 patients underwent CABG, of whom 310 died during five years' follow up. Information on QoL after five years was available in 1431 survivors (79%). There were three independent predictors for an inferior QoL with all three instruments: female sex, a history of diabetes mellitus, and a history of chronic obstructive pulmonary disease. Multivariate analysis showed that a poor preoperative QoL was a strong independent predictor for an impaired QoL five years after CABG. An impaired QoL was also predicted by previous disease. CONCLUSIONS—Female sex, an impaired QoL before surgery, and other diseases such as diabetes mellitus are independent predictors for an impaired QoL after CABG in survivors five years after operation.

- AIM: To describe the improvement in various aspects of quality of life (QoL) after coronary artery bypass grafting (CABG), in relation to a previous history of diabetes mellitus. PATIENTS: All patients from western Sweden who underwent CABG between 1988 and 1991 without simultaneous valve surgery. METHODS: Patients were approached with three questionnaires: The Physical Activity Score, the Nottingham Health Profile and the Psychological General Well-being Index prior to surgery and 3 months, 1 and 2 years thereafter. RESULTS: All three questionnaires already showed a significant improvement in QoL after 3 months, remaining at a similar level 1 and 2 years after the operation. In terms of Physical Activity Score improvement was of similar magnitude in diabetic and non-diabetic patients. In terms of the Psychological General Well-Being Index significant and similar improvements were found in diabetic and non-diabetic patients at each evaluation. In terms of the Nottingham Health Profile there was a significant improvement both in diabetic and non-diabetic patients 3 months, 1 and 2 years after the operation. However, improvement was more marked in diabetic than in non-diabetic patients at each evaluation. CONCLUSION: For 3 months, 1 and 2 years after CABG various aspects of QoL as estimated with three different instruments, improved significantly both in diabetic and in non-diabetic patients compared with the situation prior to the operation. However, the three instruments differed somewhat. Thus, whereas in the Physical Activity Score, diabetic patients tended to improve less markedly than non-diabetic patients, the opposite was found in the Nottingham Health Profile.

- To describe the impact of a history of diabetes mellitus on the improvement of symptoms and various aspects of quality of life (QoL) during 5 years after coronary artery bypass grafting (CABG). Patients who underwent CABG between 1988 and 1991 in western Sweden were approached with an inquiry prior to surgery and 5 years after the operation. QoL was estimated with three different instruments: Physical Activity Score (PAS), Nottingham Health Profile (NHP) and Psychological General Well-Being (PGWB) index. 876 patients participated in the evaluation, of whom 87 (10%) had a history of diabetes. Symptoms of dyspnea and chest pain improved both in diabetic and non-diabetic patients. Diabetic patients scored worse than non-diabetic patients both prior to and 5 years after CABG, but without any major difference in improvement between the two groups with all three measures of QoL. PAS tended to improve more in non-diabetic than in diabetic patients, whereas improvement in NHP and PGWB was similar regardless of a history of diabetes. Diabetic patients differ from non-diabetic patients having an inferior QoL both prior to and 5 years after CABG. Both diabetic and non-diabetic patients improve in symptoms and QoL after the operation. In some aspects improvement tended to be less marked in the diabetic patients but on the whole improvement was similar compared to non-diabetic patients.

- AIM: To describe symptoms and other aspects of health-related quality of life (QoL) prior to and 5 years after coronary artery bypass grafting (CABG) in relation to a history of hypertension. METHODS: Patients who underwent CABG in western Sweden were approached prior to surgery and 5 years after the operation. Health-related QoL was estimated with the Physical Activity Score, the Nottingham Health Profile and the Psychological General Well-Being Index. RESULTS: In patients with a history of hypertension (n = 740) the 5-year mortality was 16.9% versus 12.4% among patients with no history (n = 1257; p = 0.004). Of 1717 patients available for the survey, 876 (51%) responded both prior to and 5 years after CABG. Of these, 36% had a history of hypertension. Compared with the situation prior to surgery there was an improvement in both hypertensive and non-hypertensive patients in terms of physical activity, symptoms of dyspnea and chest pain and other estimates of health-related QoL. However, physical activity and dyspnea improved less in hypertensive than in non-hypertensive patients. CONCLUSION: Five years after CABG, a marked and significant improvement in terms of symptoms and other aspects of health-related QoL was observed among both hypertensive and non-hypertensive patients. However, improvement in physical activity was less marked in patients with a history of hypertension. Overall, a history of hypertension seemed to have a minor impact on improved well-being 5 years after coronary surgery. However, because of the limited response rate the results may not be applicable in a non-selected CABG population.

- The aim of this study was to describe the relief of symptoms and improvement in other aspects of health-related quality of life 5 years after coronary artery by-pass grafting in relation to age. Patients in western Sweden were approached with an inquiry prior to surgery and 5 years after the operation. Health-related quality of life was estimated with 3 different instruments: Physical Activity Score (PAS), Nottingham Health Profile (NHP), Psychological General Well-Being Index (PGWB). Prior to surgery patients were approached either in the ward or by post and 5 years after surgery they were approached by post. A total of 1719 patients were available for the survey, of whom 876 (51%) responded to the survey both prior to and after 5 years. Among the 876 respondents 287 were <60 years, 331 were 60-67 years and 258 were >67 years. In terms of physical activity, chest pain and dyspnoea, a similar improvement was observed regardless of age. In terms of health-related quality of life questionnaires, there was an inverse association between age and improvement when using PAS and a similar trend was observed with NHP and PGWB. In conclusion, 5 years after coronary artery bypass grafting relief of symptoms and improvement in physical activity was not associated with age, whereas improvement in other aspects of health-related quality of life tended to be less marked in elderly people. Overall age seemed to have a small impact on the improved well-being 5 years after coronary surgery. However, due to the limited response rate the results may not be applicable to a non-selected coronary artery bypass grafting population.

- OBJECTIVE: To describe the changes in various aspects of quality of life (QOL) from before coronary artery bypass grafting (CABG) to 5 years after the procedure. PATIENTS AND METHODS: Patients who underwent CABG in the western region of Sweden in 1988-1991 were approached with questionnaires evaluating their QOL prior to and 3 months and 1, 2, and 5 years after the operation. Three different instruments were used: the Nottingham Health Profile, the Psychological General Well-Being Index, and the Physical Activity Score. RESULTS: In all 2121 patients underwent CABG, of whom 310 died during 5 years of follow-up. With all three instruments QOL had improved 5 years after CABG compared with prior to the operation. However, all three instruments revealed a slight but significant deterioration in estimated QOL between 2 and 5 years after CABG. CONCLUSIONS: QOL 5 years after CABG is better than that prior to the operation, but between 2 and 5 years after the operation a slight deterioration in QOL is observed.
