Abstract:Heart failure (HF), as one of the most severe cardiovascular diseases, has shown a continuous rise in incidence in recent years. Its pathogenesis is closely associated with epigenetic regulation, among which N6-methyladenosine (m6A) methylation — the most common post-transcriptional epigenetic modification in the genome — plays a crucial role in the occurrence and progression of HF. This review first outlines the basic concepts of m6A methyltransferases, m6A demethylases, and m6A-binding proteins, as well as their roles in the pathogenesis of HF. Subsequently, it explores the potential mechanisms of m6A methylation in HF from aspects including autophagy, apoptosis, calcium homeostasis, and inflammatory response, aiming to provide a reference for future relevant research.
