oral iron supplementation with ferric maltol in treating iron deficiency and anaemia in patients with heart failure (orion-hf)

Conditions: Heart Failure, Left-sided; Anemia, Iron Deficiency

Summary: this is an open-label, single arm, multicenter pilot-study to explore the safety, tolerability and efficacy of oral iron supplementation with ferric maltol in treating iron deficiency and anaemia in patients with heart failure.
