Implication
Review reveals three distinct pathways of cellular iron loss in heart failure patients, highlighting therapeutic targets beyond systemic iron depletion.
Key Points
- Three distinct mechanistic pathways drive iron deficiency in heart failure, involving systemic erythropoiesis impairment and tissue-specific intracellular depletion.
- A transferrin saturation below 15% to 16% predicts clinical benefit from intravenous iron, whereas myocyte depletion occurs independently of baseline haemoglobin.
- Highlights that targeted intravenous iron can prevent ventricular remodelling and progressive cardiomyopathy, even when circulating hypoferraemia remains absent.
