AIM: To analyse the incidence, risk factors and clinical outcomes of late graft failure after heart transplantation.
METHODS AND RESULTS: We conducted an observational, single-centre study based on 547 patients who underwent cardiac transplantation from 1991 to 2014 and who survived the in-hospital postoperative period. Late graft failure was defined as the first hospitalization due to this condition after discharge. Over a mean follow-up of 8.4 ± 6 years, 178 (32.5%) patients were hospitalized due to late graft failure [incidence rate: 3.6 cases per 100 patient-years, 95% confidence interval (CI) 3.1-4.2]. Pre-transplant diabetes, higher pre-transplant transpulmonary pressure gradient and lower donor-recipient weight ratio were independently associated with higher risk of graft failure. Cardiac allograft vasculopathy, cellular rejection grade ≥1R, and antibody-mediated rejection grade ≥1 were detected in 50.6%, 44.9% and 19.2% patients, respectively, admitted due to graft failure. Left ventricular ejection fraction was ≥50% in 60.1% of these patients. Re-transplant free survival 1, 5, 10 and 15 years after the diagnosis of late graft failure was 72.2%, 38.4%, 18.4%, and 7.5%, respectively; the incidence rate of re-hospitalization due to decompensated heart failure was 40.9 episodes per 100 patient-years (95% CI 36.6-46.1). The need for inotropes, the presence of cardiac allograft vasculopathy, higher creatinine serum levels, lower ejection fraction and lower sodium serum levels were independent predictors of worse outcomes.
CONCLUSIONS: Late graft failure is frequent after heart transplantation, as it is associated with poor outcomes. Rejection and cardiac allograft vasculopathy are the most frequent underlying causes.
