Objective:To identify the correlation between in-stent restenosis and coronary calcification after percutaneous coronary intervention,so as to provide clinical basis and guidance countermeasures for CHD treatment.Methods:Patients underwent PCI and coronary angiography reexamination completed in the Central Catheterization Room,The Fourth Affiliated Hospital of Harbin Medical University from June 2014 to June 2019 were collected,and coronary angiography reexaminations were performed.According to the reexamination results,the patients were divided into ISR group and non-ISR group.The general clinical data and interventional imaging data of the two groups of patients were retrospectively acquired,and the above data was analyzed by single-factor analysis and multivariate logistic regression analysis.Results:Compared with the non-ISR group,the percentage of calcification in the ISR group increased significantly(x2=0.444,P＜0.05).The rate of calcification,stent overlap and small diameter stent in ISR group were higher than those in non-ISR group,with statistically significant difference(x2=1.192,0.180,1.491;P＜0.05).Binary logistic regression analysis showed that calcified plaque,diabetes and small diameter stents were independent risk factors for ISR after PCI.Conclusion:PCI treatment for coronary artery calcification is an independent risk factor for ISR,especially in patients with diabetes mellitus and small vascular diameter of the target lesion requiring implantation of small-diameter stents.
