ABSTRACT
Objective To study the changes of plasma cystatin C level (PcyC),and evaluate the effects of the joint use of atorvastatin and probucol on PcyC and severity of coronary lesion in patients with borderline lesion of coronary artery.Methods One hundred and thirty consecutive patients with borderline coronary lesion assessed by quantitative coronary angiography were enrolled into borderline coronary lesion group (BCL),and another 136 subjects without coronary lesion were enrolled as controls (CTR).And in the meantime,the subjects in BCL group were randomized (closed envelope method) into routine treatment subgroup ( RTT,n =60),and combined treatment subgroup in which patients were treated with atorvastatin 20 mg plus probucol 1.0 g daily in addition to routine medication ( CBT,n =70) for 6 months.There were no statistical differences in basic clinical features between two subgroups.PcyC,high-sensitive C-reactive protein (hs-CRP),total cholesterol (TC),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol ( HDL-C ) and triglycerides (TG) were determined.Of them,104 patients in BCL group rechecked by coronary angiography.Comparison of biomarkers carried out between two groups by using a number of independent-sample t-test and analysis of variance.For enumeration data,chi-square test was used to compare mean values of biomarkers between groups. P < 0.05 was considered statistically significant.Results PcyC levels were significantly higher in BCL group than those in CTR group ( P < 0.05 ).Compared with RTT subgroup,levels of PcyC,TC,LDL-C,TG and hs-CRP were more significantly decreased in CBT subgroup (P < 0.05,P < 0.01 ).Moreover,there was a trend of slight decrease in the mean percent of stenosis (MPS) of coronary artery with borderline lesion in RTT subgroup treated for 6 months,whereas more marked decrease in the MPS of coronary artery with borderline coronary lesion in CBT subgroup treated for 6 months ( P > 0.05 ; P < 0.05 ).Conclusions Cystatin C plays an important role in the pathogenesis of coronary artery,and PcyC is associated with severity of coronary lesion,the combination of atorvastatin and probucol decreases the PcyC level,and it may be the treatment of choice for borderline lesion of coronary artery.
