Serum CyPA level change in patients with coronary heart disease and its clinical significance / 重庆医学

ABSTRACT

Objective To observe the serum cyclophilin A(CyPA)level change in the patients with coronary heart disease (CHD)and to investigate its clinical significance.Methods 64 patients with CHD(CHD group)were divided into three groups ac-cording to the clinical typesstable angina pectoris(SAP)group,unstable angina pectoris(UAP)group and acute myocardial infarc-tion(AMI)group;which were divided into three groups according to the coronary artery lesion rangesingle vessel lesion group, double vessels lesions group and multi vessels lesions group;while 26 controls with normal coronary arteries were select as the con-trol group.Serum levels of CyPA and matrix metalloproteinase-9 (MMP-9 )were detected by ELISA,and C-reactive protein(CRP) concentration was detected by the immune scattering turbidimetry test.Results The CyPA,MMP-9 and CRP levels in the CHD group were significantly higher than those in the control group(P0.05);serum CyPA,MMP-9 and CRP levels in the single vessel lesion group,the double vessels lesion group,multi vessels lesion group were significantly higher than those in the control group(P<0.05),serum CyPA,MMP-9 and CRP levels were elevated with the increase of coronary artery lesion vessels (P<0.05).In the CHD group,serum CyPA with MMP-9 and CRP showed the significantly positive correlation(r=0.772,0.749, P<0.01).Conclusion Serum CyPA level is significantly increased in the patients with CHD,CyPA may have some relationship to CHD and the plaque stability.
