摘要

Iron deficiency has been reported in up to 50% of patients with heart failure (HF), irrespective of the presence of anemia. Although no formally validated definition for iron deficiency in patients with HF exists, both the American and European Heart Failure Guidelines define iron deficiency as a serum ferritin of < 100 ng/ml, or a ferritin of 100–299 ng/ml, provided that the transferrin saturation (TSAT) is less than 20%. The presence of iron deficiency has been associated with poor patient-oriented outcomes, prompting the assessment of intravenous (IV) iron as a treatment for iron deficiency. This review summarizes the totality of the evidence on the diagnosis, evaluation and treatment of patients with iron deficiency. In addition, we highlight our approach to patients with HF with reduced ejection fraction and highlight areas for both clinical improvement and research.
