VEGFA and acute myocardial infarction: miR126, expressed mainly in the heart, lungs, and digestive tract, exerts its effects by regulating vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF) pathway activity [63] and is therefore responsible, among other processes, for vascular aging and angiogenesis and has proven a highly sensitive and specific marker for acute myocardial infarction (AMI) [64].
