L-Arginine Supplementation and Exercise; L-Arginine Supplementation and Renal Function
Effects of Oral Chronic L-Arginine Supplementation on Exercise and Renal Function of Heart Transplant Recipients
  • 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
