Parenteral Iron in Heart Failure: An Indian Perspective

Iron deficiency (ID) is clinically significant comorbidity usually reported with acute and chronic heart failure (HF) and associated with prognostic outcomes, independent of anemia. The exact cause of ID and anemia and their association with HF is not entirely clear. Current evidence highlights neuro-hormonal and proinflammatory cytokine activation and renal dysfunction favoring the development of anemia and ID. Intravenous iron therapy (IV Iron) enhances exercise capacity, HF-associated symptoms and health-related quality of life. Oral iron therapy might be less effective compared to IV Iron in HF patients. At the same time, large, well-designed cardiovascular outcome studies are warranted to establish the long-term efficacy and safety of IV Iron in patients with HF with coexisting ID. In India, the high prevalence of anemia increases the burden of ID in patients with HF. HF being a complex multifactorial disease, it is essential to understand the association of ID with HF which can be easily corrected to improve the patient outcomes. At the same time, there is a need to generate more robust clinical evidence on IV Iron therapy for in Indian patients of HF.
