Iron deficiency and anaemia in heart failure: understanding the FAIR-HF trial.

Treatment of anaemia in patients with chronic heart failure (CHF) and reduced left ventricular ejection fraction has traditionally focused on erythropoietin-stimulating agents. However, recent studies have shown that treatment with intravenous (IV) iron can improve the symptoms and quality of life in patients with CHF and iron deficiency (ID), with or without anaemia. The management of ID is becoming an important therapeutic target in patients with CHF, and in this article, we will review iron metabolism in the context of anaemia and heart failure. We will also focus on the importance of diagnosing and treating ID, preferably with IV iron preparations, in patients with CHF.
