Association of AIP and serum bilirubin with coronary in-stent restenosis / 西安交通大学学报(医学版)

ABSTRACT

Objective To analyze the association of atherogenic index of plasma (AIP)and serum bilirubin with coronary in-stent restenosis after drug-eluting stent implantation.Methods For this research we recruited 268 patients who had undergone successful drug-eluting coronary stent implantation and then received coronary angiography.Both ends (from the edge of the supporting frame≤5 mm)or the vessel's diameter stenosis ≥50% were used as the definition of restenosis.According to the results of coronary angiography,the subjects were divided into restenosis group (42 cases)and non-restenosis group (226 cases).The total bilirubin,direct bilirubin,indirect bilirubin and AIP in the two groups were compared to explore the correlation of AIP and serum bilirubin with in-stent restenosis.Results AIP in restenosis group was significantly higher than that in non-restenosis group (P＜0.05).The level of total bilirubin was significantly lower in the former group than in the latter one (P＜0.05). Conclusion AIP is a risk factor for restenosis,and serum total bilirubin is a protective factor for coronary stent restenosis.
