  • exercise capacities are still altered after heart transplantation partly due to peripheral endothelial dysfunction
  • cyclosporin-induced renal dysfunction may be due to renal endothelial dysfunction and can be reversed in an animal model by L-arginine supplementation
  • to determine the potential beneficial effect of L-arginine supplementation on exercise capacity and renal function of heart transplant recipients

Condition Intervention Phase
Heart Transplantation Drug: 12 g of L-arginine glutamate during 6 weeks twice a day Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: Effects of Oral Chronic L-Arginine Supplementation on Exercise and Renal Function of Heart Transplant Recipients
