Expert consensus on the importance of iron deficiency and the possibility of its correction in patients with heart failure.

Anemia and iron deficiency are common non-cardiovascular comorbidities of heart failure. The prevalence of iron deficiency is up to 55 % of patients with chronic heart failure and up to 80 % subjects with acute heart failure including acute decompensated heart failure, independently on anemia. The European Society of Cardiology Heart Failure Guidelines 2021 recommend intravenous iron replacement in patients with heart failure and iron deficiency to improve symptoms, stress tolerance and quality of life in chronic heart failure and to reduce risk of subsequent hospitalization after acute decompenstation.
