Studies have shown that salidroside can effectively improve the vasoconstrictor function of vascular endothelium and promote the angiogenesis of ischemic myocardium in rats by affecting the expression of vascular endothelial growth factor (VEGF), promote the angiogenesis of ischemic myocardium in rats, and protect the myocardial ischemia-reperfusion injury. This evidence concerns the gene VEGFA and myocardial ischemia.
