Abstract
Amidst several pathophysiological cascades, Advanced Glycation End products (AGEs) have been identified as a pivotal aetiology behind the pathogenesis and progression of cardiovascular disorders, by inducing oxidative stress and inflammation of myocardial and vascular tissues. Non-enzymatic glycation of reducing sugars with amino acids in proteins, lipids, and nucleic acids produce AGEs, which are a diverse set of compounds. Although AGEs are mostly generated endogenously, current research suggests that nutrition is a major exogenous source of AGEs. Extracellular and intracellular structure and function are affected by the presence and accumulation of AGEs in several cardiac cell types. AGEs give rise to several microvascular and macrovascular problems by establishing cross-links between molecules in the extracellular matrix's basement membrane as well as interacting with receptors for advanced glycation end products (RAGE). The transcription factor nuclear factor kappa B and its RAGE target genes are upregulated when RAGE is activated by AGEs. Engagement increases oxidative stress and triggers inflammatory and fibrotic responses, all of which contribute to the onset and progression of life-threatening cardiovascular diseases. This article discusses the probable targets of glycation in cardiac cells, as well as the underlying mechanisms that lead to heart failure.
