Quality of life in elderly patients following coronary artery bypass grafting

BACKGROUND Surgical revascularization of the coronary arteries leads to changes in quality of life (QoL) for patients with coronary heart disease. The aim of this work was to monitor QoL, considering cognitive function, depression, and activities of daily living in elderly patients after coronary artery bypass grafting (CABG). METHODS This study included 65 patients (29 women and 36 men) aged 61-74 years with stable coronary heart disease who underwent CABG. The control group included 29 women and 36 men aged 61-74 years who were not suffering from coronary heart disease. The questionnaires used in the study canvassed QoL (Nottingham Health Profile), cognitive function, depression, and basic and instrumental activities of daily living. The research was conducted before surgery and repeated 6 and 12 months after surgery. RESULTS QoL was comparable between women and men and was lower than in the control group (P<0.05). After CABG, the values for particular domains of QoL improved more in men than in women. There was a reduction in the severity of depression 6 months after surgery in men and 12 months after surgery in women. CONCLUSION Elderly patients with coronary heart disease have decreased QoL, which normalizes in men and improves in women after CABG.
