Effect of Atorvastatin on Endothelial Function in Hypertensives Without Hyperlipemia / 中华高血压杂志

ABSTRACT

Objective To investigate the effect of different dose of atorvastatin on endothelium dependent vasodilatation function in hypertensives without hyperlipemia in attempt to verify the hypothesis of "beyond antihyperlipimia" effect of statins.Methods Fifty-five hypertensives without hyperlipemia were randomly to receive atorvastatin(10 mg/d,n=25)or(20 mg/d,n=30).Twenty-five normotensives were enrolled in control group.Serum cholesterol were determined.Flow-mediated dilation(FMD)and endothelium-independent dilatation(EID)were measured with high-resolution ultrosonography before and after 4 weeks atorvastatin.Results Compared with control group,FMD were significant decreased in hypertensives without hyperlipemia.FMD were improved after atorvastatin for 4 weeks(atorvastatin 10 mg group7.5%?2.7% vs 11.5%?3.1%,P
