Abstract

Abstract: Objective To investigate the predictive significance of oxidized low-density lipoproteins(ox-LDL) and C reactive protein(CRP)for in-stent restenosis(ISR)after percutaneous coronary intervention(PCI). Methods A total of 186 patients who were given PCI and followed up for 6 months were enrolled. Of them, 22 patients had ISR(ISR group), while the other 164 patients had not ISR(no-ISR group). The pre- and post-PCI serum ox-LDL and CRP were detected. Results There was no statistical significance between the 2 groups in terms of age, sex, morbidity, serum lipid and vessel lesion(P>0.05). Serum ox-LDL and CRP increased significantly in ISR group at post-PCI compared with pre-PCI (P<0.05), while there was no significant change in no-ISR group (P>0.05). Serum ox-LDL were also higher in ISR group compared with no-ISR group at pre- and post-PCI(P<0.05). There was no statistical significance for CRP level between the 2 groups at pre-PCI (P>0.05). However, the significant increase of CRP level in ISR group compared with no-ISR group was present at post-PCI(P<0.05). Correlation analysis revealed that there was positive correlation between pre- and post-PCI for serum ox-LDL and CRP in both ISR and no-ISR groups [ISR group: r(P) values of pre- and post-PCI were 0.392(0.020) and 0.431(0.010); no-ISR group: r(P) values of pre- and post-PCI were 0.382(0.024) and 0.526(0.001)]. The Logistic regression analysis showed that post-PCI ox-LDL[odds ratio (OR)=1.27, 95% confidence interval(CI): 1.05-1.79]and pre-PCI CRP(OR=1.82,95%CI:1.68-2.30)were independent risk factors of ISR. Conclusions Post-PCI ox-LDL and pre-PCI CRP have certain significance in the prediction of ISR.
