Abstract:

Objective: To evaluate correlation of estimated glomerular filtration rate with occurrence of in-stent restenosis (ISR) in patients treated with drug-eluting stent(DES) implantation during follow-up period. Methods: Patients undergone DES implantation in the RIPPER study between January 2010 and July 2016 were enrolled, and coronary angiography was performed again to detect ISR after 12-24 months (with the average time of 13 months). Binary Logistics regression were used to assess the risk factors for in-stent restenosis (ISR), and evaluate the correlation of eGFR with ISR in patients. Results: A total of 1 790 patients meeting the inclusion criteria, with the average eGFR of 89.97 mL/(min·1.73 m2) during follow-up, were divided into ISR group (n=200) and No-ISR group (n=1 590). The eGFR in ISR group was significantly lower than No-ISR group [(86.50±25.69) mL/(min·1.73 m2) vs. (90.64±26.59) mL/(min·1.73 m2), P=0.038]. Binary Logistics regression showed that the risk factors for ISR were number of implanted stent[OR=1.478, 95% CI 1.177-1.855, P=0.001] and increased baseline C-reactive protein level [OR=1.006, 95%CI 1.002-1.011, P=0.007], while relatively elevated eGFR during follow-up was protective factor(OR=0.990, 95%CI 0.982-0.999, P=0.022.Conclusions: In patients with nearly normal eGFR after DES implantation, relatively lower eGFR is correlated with the incidence of ISR.
