ABSTRACT
Objective:
To explore protective effect of atorvastatin on blood vessels in early stage of atherosclerosis (AS).Methods:
A total of 120 patients without AS plaques,who had >2 cardiovascular risk factors and received control cardiovascular risk factors therapy,were randomly divided into four groupscontrol group (did not receive atorvastatin),atorvastatin 5mg group,10mg group and 20mg group (received corresponding dose of atorvastatin). All patients were followed up for six months,changes of thromboxane B2 (TXB2),6-Keto-prostaglandin F1α (6-Keto-PGF1α),brachial-ankle pulse wave velocity (baPWV),ankle brachial index (ABI)and intima-media thickness (IMT)were observed.Results:
There were no significant changes in ABI and IMT between before and after treat-ment among four groups (P >0.05 all).Compared with baseline,TXB2、baPWV levels significantly rose,6-Keto-PGF1αlevel significantly decreased after treatment in control group and 5mg group;in contrast,TXB2、baPWV lev-els significantly decreased,6-Keto-PGF1αlevel significantly rose after treatment in 10mg group and 20mg group(P <0.05~ < 0.01).After treatment six-month,compared with control group and 5mg group,the TXB2 [(148.3 ± 29.2)pg/ml,(142.3±30.6)pg/ml vs.(111.5±22.8)pg/ml,(104.9 ± 17.4)pg/ml]、baPWV[(1621.1 ± 136.1) cm/s,(1597.7±125.3)cm/s vs.(1232.9±132.3)cm/s,(1178.2±155.1)cm/s]levels significantly decreased,6-Keto-PGF1α[(104.7±66.1)pg/ml,(102.2±70.3)pg/ml vs.(132.8±48.3)pg/ml,(139.1±66.3)pg/ml]level significantly rose(P <0.05~<0.01)in 10 mg group and 20 mg group.Conclusion:
Atorvastatin has protective effect on blood vessels in early stage of atherosclerosis,and 10mg atorvastatin may be the minimum effective dosage to protect blood vessels.
