Neuropeptides Y and Other Promising Biomarkers in Acute Coronary Syndrome

Neuropeptide Y (NPY) is a very common neurotransmitter with 36 amino acids that acts as a stimulator of angiogenesis, inflammation and adipogenesis through the NPY2 receptor. The description of high plasma concentrations of NPY in acute coronary syndrome (ACS) and left ventricular dysfunction and its close relationship with the sympathetic nervous system reinforces the possibility of a new prognostic biomarker for risk stratification.^,

In recent years, changes in the NPY signalling pathway have been related to ACS. For example, the NPYc.20T>C mutation is associated with increased serum lipid levels and consequent increase in the risk of ACS, stroke, hypertension, and obesity.^, The NPYc.-485T>C variant has been linked to the development of early atherosclerosis and stroke, and possibly to insulin resistance reduction and development of type 2 diabetes mellitus.^–
