Heart-to-heart evaluation could lead to tissue regeneration therapies
A heart attack, technically a myocardial infarction, is generally an ischaemic event in which vital oxygen and nutrients are denied to heart muscle (myocardium), because of either a vessel blockage or rupture. This typically results in tissue death and subsequent scarring, diminishing the heart's capacity to pump blood efficiently. Over time, this can potentially lead to heart failure. The human heart does not regenerate cells and tissue; likewise, introduction of stem cells has not been associated with regeneration. However, some fish and amphibian species can regenerate their hearts. The EU-funded REANIMA project is studying the presence and absence of such regeneration across diverse species, seeking pathways toward regeneration and mechanisms stimulating endogenous regeneration in humans. A well-established translational pipeline could bring discoveries to the clinic speedily.
