Abstract:

Objective To observe the clinical effect of rosuvastatin inthe treatment of lower extremity atherosclerotic disease in the elderly,and to provide clinical basis of the application of statins in lower extremity atherosclerotic disease in the elderly. Methods 90 patients diagnosed as lower extremity atherosclerotic disease (aged 60 years or over)were randomly divided into simvastatin group and rosuvastatin group (n=45),and they were treated with simvastatin and rosuvastatin, respectively, based on the regular treatment.The total cholesterol(TC),low density lipoprotein-cholesterol(LDL-C),and high sensitivity C-reactive protein (hs-CRP) of the patients in two groups were detected at the begining of treatment and the ending of 32 weeks;at the same time,the lower limb artery intima thickness,strength of hardened,plaque,and artery stenosis degree scores were compared. Results 32 weeks after treatment, the levels of TC,LDL-C and hs-CRP of the patients in two groups were decreased statistically compared with before treatment (P<0.05);the levels of TC,LDC-C,and hs-CRP in rosuvastatin group were lower than those in simvastatin group(P<0.05).32 weeks after treatment in two groups,compared with before treatment,the lining thickness and plaque,stenosis scores were decreased (P<0.05); the lining thickness,plaque and stenosis scores in rosuvastatin group were lower than those in simvastatin group (P<0.05);the gardening strength grades had no statistical difference between before and after treatment. Conclusion Statins is lipid-lowering and resistant to lower limb arteriosclerosis,and rosuvastatin is better than simvastatin.
