Influence of Short-term Rosuvastatin Therapy on Endothelial Progenitor Cells and Endothelial Function
2009
Endothelial progenitor cells maintain endothelium integrity by replacing injured endothelial cells. Cholesterol-lowering promotes either endothelial progenitor cells mobilization or improves endothelial function. It is unknown whether improving endothelial function with statin is associated with a parallel increased endothelial progenitor cells availability. Thirty-two hypercholesterolemic patients were assigned to 4-week rosuvastatin (10 mg daily) and 16 hypercholesterolemic served as controls. Circulating endothelial progenitor cells, brachial artery flow-mediated vasodilatation, an index of endothelial function, and the lipid profile were measured before and after the 4-week statin therapy. At baseline, we found a correlation between circulating endothelial progenitor cells and flow-mediated vasodilatation (r = .31, P = .029). At the end of the 4-week intervention with rosuvastatin there was a 37% reduction in low-density lipoprotein cholesterol (P < .001) and a significant 72% increase in the number o...
