Impact of a history of diabetes on the improvement of symptoms and quality of life during 5 years after coronary artery bypass grafting.
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.
