Schematic representation of the possible mechanism of effects of pitavastatin and atorvastatin on endothelial progenitor cells (EPCs). Atorvastatin decreased serum asymmetric dimethylarginine (ADMA) and pitavastatin increased serum vascular endothelial growth factor (VEGF), both increasing the expression of total form endothelial nitric oxide synthase (eNOS) in late EPCs. Only pitavastatin could increase circulating EPCs number and function via enhancing eNOS activity.
