OBJECTIVE
To
investigate the long term outcome and prognostic factors after heart transplantation.
SETTING
University hospital.
SUBJECTS
120 heart
transplant patients (98 male, 22 female; underlying disease: dilated
cardiomyopathy in 69, coronary artery disease in 42, miscellaneous in
nine) who had undergone heart transplantation between October 1984 and
October 1987. Immunosuppressive treatment was comparable in all
patients and rejection episodes were treated in a uniform manner.
METHODS
Functional
status, quality of life, and potential predictors for long term
survival were investigated.
RESULTS
Actuarial
survival rates were 65% at five years and 48% at 10 years; 58 patients survived > 10 years. The major causes of death were cardiac
allograft vasculopathy (39%), acute rejection (18%), infection
(11%), and malignancy (11%). Long term survivors had good exercise
tolerance assessed by the New York Heart Association classification: 47 (81%) in grade I/II; 11 (19%) in grade III/IV. Echocardiography
showed good left ventricular function in 48 patients. On angiography,
severe allograft vasculopathy was present in only 16 patients (28%).
Renal function was only slightly impaired, with mean (SD) serum
creatinine of 148.5 (84.9) µmol/l. Multiple potential predictors of
long term survival were analysed but none was found useful.
CONCLUSIONS
Heart
transplantation represents a valuable form of treatment. Survival for
more than 10 years with a good exercise tolerance and acceptable side
effects from immunosuppression can be achieved in about 50% of patients.
