BACKGROUND AND METHODS: Risk factors for death after primary heart transplantation were identified by analyzing our total experience with 234 patients who underwent transplantation at our institution from May 28, 1979, to May 27, 1996. RESULTS: There were 205 male and 29 female patients. Mean recipient age was 48.5+/-10.9 years (standard deviation). Recipient diagnosis included ischemic cardiomyopathy in 103 (44%), idiopathic cardiomyopathy in 98 (42%), valvular heart disease in 17 (7%), congenital heart disease in 4 (2%), and other diagnoses in 12 (5%) patients. Donor age was 32+/-10.2 years. Graft ischemic time was 138.1+/-51.8 minutes. The operative mortality rate was 23.5%. Actuarial survival estimates for all patients at 1, 5, and 10 years were 62%, 50%, and 44%, respectively. The three most common causes of death (both early and late) after primary heart transplantation were infection (27.4%), acute rejection (18.9%), and early graft failure (17.9%). Multivariate logistic regression analysis identified older recipient age (p = 0.007), higher preoperative pulmonary vascular resistance (p = 0.01), recipient preoperative hepatic insufficiency (p = 0.001), and gender mismatch (p = 0.02) as independent predictors of early death (within 3 months of the procedure). Multivariate proportional hazard regression analysis revealed that recipient idiopathic cardiomyopathy (p = 0.02) and recipient preoperative liver failure (p = 0.01) were independent risk factors for late death (after 3 months). CONCLUSION: These results underscore the importance of adequate recipient selection and recipient/donor matching for short- and long-term survival after primary heart transplantation.
