Abstract:
ObjectiveTo research the endothelial dysfunction and early changes in arterial elasticity in patients with hyperlipidemia and effects of atorvastatin on these changes.Methods40 patients with hyperlipidemia but without any treatment in our hospital were selected as a study group,and 30 healthy people were selected as control group.Use the Flow mediated dilation,FMD detection which bases on the echo-trackingtechnology,eTRACYING to evaluate the right brachial atherosclerosis parameters and vascular diastolic parameters,including the pressure strain elastic modulus(Ep) ;stiffness index (β) ;compliance (AC) ;FMDs and FMDd.The study group take atorvastatin 20mg per day,then retested above parameters and TC,LDL-C after 12 weeks and analyzed all parameters.ResultsThe values of β and Ep in study group are significantly higher than the control group (all P ＜ 0.001 ),but AC;FMDs and FMDd are significantly lower than the control group( all P ＜ 0.001 ).The results of the study group after the treatment of atorvastatin are as follwing:TC,LDL-C,β and Ep are lower than before,AC,FMDs and FMDd are higher than before;and the differences are of significance in statistics ( all P ＜ 0.001 ).ConclusionHyperlipidemic patients had shown the vascular endothelial injury and vascular early hardening before the abnormal changes in intimal,but the atorvastatin intervention could reverse these changes.
