Anemia and Iron Deficiency in Heart Failure : Clinical and Prognostic Role

Anemia and iron deficiency (ID)represent 2 prevalent, often interrelated, comorbidities in heart failure (HF). Both of them are significantly related to functional capacity and are undoubted predictors of poor prognosis in patients with HF. Although anemia and ID both have “global” detrimental effects, these 2 conditions are too often overlooked in cardiology daily clinical practice. The present review sought to summarize briefly the prevalence and the underlying pathophysiologic mechanisms of anemia and ID as regards HF severity (ie, exercise capacity)and prognosis.
