Psychosocial function improves after cardiac transplantation but the extent of improvement is not established. Neither are the factors established that account for variability in function between patients following successful transplantation. We therefore compared illness-related dysfunction in patients following orthotopic cardiac transplantation (OCT) with that in angina-free patients following coronary artery bypass graft (CABG) and stable patients in heart failure awaiting transplantation (HF). We also measured two factors that might contribute to variation in function: emotional distress and concern with physical symptoms. Psychosocial function was as good in OCT as in CABG patients and, in both, was better than in HF patients. Differences in emotional distress and in physical symptoms showed a similar pattern and contributed to, but did not completely account for, differences in function. Concern with physical symptoms contributed to variability in functional impairment in HF but not CABG patients; transplantation strengthened this relationship. The results show that successful cardiac transplantation enhances psychosocial function to a level comparable with that after CABG, and suggest targets for psychological or educational intervention to improve quality of life after transplantation in patients whose recovery is inhibited by concern about physical symptoms.
