Abstract:
Objective To observe the effects of grape seed proanthocyanidin extract (GSPE)combined with atorvastatin on carotid atherosclerosis of the elderly. Methods Consecutivly 122 patient aged( 73.2 ±12.8) years with hypercholesterolemia and diagnosed as asymptomatic carotid artery plaques were randomly assigned to single atorvastatin(20 mg/d) treatment group (n=63) and combination treatment (atorvastatin 10 mg/d plus GSPE 400 mg/d) group (n=59).Serum total cholesterol (TC),triglyceride (TG),low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C) and high-sensitive C-reactive protein (hs-CRP) levels were detected before treatment and 3,6,12 months after treatment.Mean maximum carotid intima-media thickness (CIMT),plaque score and stability were also assessed by carotid ultrasound. Results After 3 months of treatment,serum levels of TC,TG and LDL-C in both groups were lower than before treatment (all P<0.01),but no difference was found between the two groups (P>0.05).HDL-C levels was enhanced by 20.2% in combination treatment group after 3 months of treatment (P<0.05),there was difference after 6 months treatment between two groups (P<0.05).Serum hs-CRP concentrations were decreased by 1.7 mg/L and 3.6 mg/L,3.8 mg/L and 6.3 mg/L,5.9 mg/L and 8.3 mg/L after 3,6 and 12 months treatment as compared with pretreatment,respectively in the two groups (P<0.05 or P<0.01).There was difference in hs-CRP levels between groups after 6 and 1.2months of treatment (P<0.05 or P<0.01).There were MMCIMT reduction by 1.3% and 2.0% (P>0.05),3.4% and 5.3%(P>0.05 and P<0.05 ),5.1% and 8.6% after 3,6 and 12 months of treatment(P<0.05 and P<0.01) in the two groups,with distinct difference after 12 month treatment (P< 0.01 ).The plaque scores were declined by 6.8 % and 13.1% ( both P > 0.05 ),14.5 % and 28.0% (P>0.05 and P<0.05),19.2% and 45.0%(P<0.05 and P<0.01)after 3,6 and 12 months of treatment while significant difference was found between the two groups after 12 months treatment (P<0.05).Unstable plaque and the total number of plaque was dropped by 8 and 14 in single group,19 and 28 in combination group,respectively,after 12 months of treatment. Conclusions GSPE combined with atorvastatin may inhibit the development of carotid intima-media thickness,reduce carotid plaque and promote stabilization of carotid plaque.
