How iron release may worsen heart failure Written by James Kingsland on February 5, 2021 Fact checked by Hilary Guite, FFPH, MRCGP Drazen Zigic/Getty Images Iron-containing molecules play a wide range of essential roles in the body, including transporting oxygen in the bloodstream. However, a study in mice suggests that in cases of heart failure, the release of stored iron in the heart may contribute to the death of heart muscle cells.
