Brief Summary:

Recently, growing body of evidence support the finding that anemia frequently occurs in patients with chronic heart failure (CHF). Chronic kidney disease (CKD), as well, is highly prevalent among heart failure patients, and both anemia and CKD are independently associated with increased mortality. A vicious circle is established with CHF causing both chronic renal insufficiency and anemia, and CKD further aggravating anemia which, in turn, worsens CHF and so on. Treatment of the anemia breaks this circle and improves the quality of life, cardiac and renal functions in patients with severe CHF.

Intravenous iron alone was proved to allow the maintenance of target hematocrit in one-third of chronic renal failure predialysis patients.

Based on these considerations, intravenous iron for anemia in patients with CHF and moderate CKD would represent a reasonable therapeutic approach.

The aim of the trial is to assess the efficiency of intravenous iron therapy in the management of mild to moderate anemia associated with CHF NYHA III class and concomitant moderate CKD.
