Anemia in heart failure: should we supplement iron in patients with chronic heart failure?
Study Goal
The researchers aimed to evaluate the efficacy of iron supplementation for treating anemia in patients with congestive heart failure (CHF) and its impact on symptoms and functional status.
Results Summary
The abstract indicates that numerous clinical studies have examined iron supplementation for anemia in CHF patients, but no clear superiority of this approach has been established. Data from large randomized trials on the effect of anemia correction on patient outcomes are still lacking.

Anemia has been identified as an independent prognostic factor of both morbidity and mortality for patients with congestive heart failure (CHF). The association between anemia and adverse outcomes has raised the hypothesis that anemia correction might lead to an improvement in the prognosis of patients with CHF. Nevertheless, data from large randomized trials about the effect of anemia correction on patient outcome are still lacking. Numerous clinical studies, randomized and nonrandomized, have evaluated the efficacy of erythropoietin or iron supplementation for treating anemia in patients with CHF, and their effect on patient symptoms and functional status. The superiority of any of these approaches has not been established yet. This review will discuss different treatment options for anemic patients with CHF, with emphasis on the correction of iron deficiency.
