Intravenous iron supplement for iron deficiency in cardiac transplant recipients (IronIC): A randomized clinical trial.
Summary
Iron deficiency is prevalent in heart transplant recipients, and may be associated with reduced functional capacity. The IronIC trial is designed to assess the effect of intravenous iron isomaltoside on exercise capacity, muscle strength, cognition and quality of life in iron-deficient heart transplant recipients
