[Why and how to treat iron deficiency in heart failure ?].

Anemia and iron deficiency are two common comorbidities in heart failure with reduced ejection fraction (HFrEF) and are associated with a poor prognosis. In contrast to iron oral supplementation, administration of intravenous ferric carboxymaltose (Injectafer®) improves quality of life, exercise capacity, and seems to reduce hospitalizations for heart failure. Unfortunately, although anaphylactic reactions are extremely rare, it is recommended to administer Injectafer® in a suitable medical environment. This limitation hinders Injectafer® administration and may cause reluctance from both physician and patient. The aim of this article is to optimize and harmonize management of iron deficiency in heart failure, by proposing a simple solution for the patient and the practitioner.
