Purpose. Development of cardiac allograft vasculopathy (CAV), renal dysfunction and malignancies are the main risks due to long-term immunosuppressive therapy after heart transplantation (HTx). We collected long-term follow-up data of a randomized HTx intervention cohort to compare the intended treatment containing tacrolimus (TAC) or cyclosporin A (CsA) both with mycophenolate mofetil (MMF).

Methods. After a mean duration of 15 years (enrollement 1998-2000) a prospective, randomized HTx cohort was analyzed as intention-to-treat. Randomized immunosuppressive regimens were TAC/MMF or CsA/MMF (n=60, randomization 1:1, corticosteroids were withdrawn after six month in patients without repeated rejection episodes, statines treatment routinely). Baseline characteristics were well balanced. CAV was graduated in accordance to the ISHLT classification.

Results: Study results are listed in the table

Conclusions. This long-term analysis reveals, that a TAC-based treatment is superior over a CsA-based treatment regarding CAV onset and serum creatinine levels. Benefit of TAC/MMF over CsA/MMF regimen did not result in better long-term survival. Cross-over effects due to treatment switch and the small study cohort should be considered in this intention-to-treat analysis.
