Analysis of correlation between carotid atherosclerotic plaques and serum hs-CRP, Apo-B, ox-LDL and MMP-9 levels in patients with atherosclerotic cerebral infarction.

Objective To analyze the correlation between the levels of serum hypersensitive c-reactive protein(hs-CRP), apolipoprotein-B(Apo-B), oxidized low-density lipoprotein(ox-LDL) and matrix metalloproteinase-9(MMP-9) and carotid arteryplaque(CAP) in patients with atherosclerotic cerebral infarction(ASCI). Methods 125 patients with ASCI diagnosed in the Department of Neurology of Panzhihua Central Hospital from January 2018 to December 2018 were selected as the case group, and 125 healthy volunteers in the same period were selected as the control group. Serum levels of hs-CRP, Apo-B, ox-LDL and MMP-9 were compared between the two groups. Carotid ultrasound was performed in patients with ASCI. The correlation between serum levels of hs-CRP, Apo-B, ox-LDL and MMP-9 and the formation of CAP in patients with ASCI was analyzed by SPSS 23.0 statistics. Results Compared with the control group, the levels of serum hs-CRP, Apo-B, ox-LDL and MMP-9 increased significantly in the case group(P<0.01). The serum levels of hs-CRP, Apo-B, ox-LDL and MMP-9 in patients with CAP were significantly higher than those without CAP in the case group(P< 0.01). Multivariate logistic regression analysis showed that serum levels of hs-CRP(OR=4.76, 95%CI:2.35-9.18), Apo-B(OR=3.16, 95%CI:1.59-7.32), ox-LDL(OR=1.48,95%CI: 1.15-2.01) and MMP-9(OR=3.86,95%CI: 1.63-9.14) were independent risk factors for CAP formation in patients with ASCI(P< 0.05). Conclusions The contents of serumhs-CRP, Apo-B, ox-LDL and MMP-9 may reflect the serverity of inflammation and instability of carotid atherosclerotic plaque in ASCI patient. The levels of serum hs-CRP, Apo-B, ox-LDL and MMP-9 in patients with ASCI are significantly increased, which are closely related to the formation of CAP in patients with ASCI, so it can be used as important serum biomarkers for clinical diagnosis of ASCI and CAP formation.
