AbstractTo explore the risk factors for in-stent restenosis (ISR) after stent implantation in patients with coronary heart disease (CHD) using logistic regression analysis. From February 2020 to February 2022, 350 patients with CHD after percutaneous coronary intervention (PCI) were divided into a stent stenosis group and a stent nonstenosis group based on coronary angiography results performed 2 years after PCI. Univariate and multivariate logistic regressions were used to analyze the factors related to ISR after coronary stent implantation in patients with CHD. This study was approved by the Ethics Committee of Shandong University of Traditional Chinese Medicine. Patient signed informed consent. Of the 350 patients with CHD, 138 (39.43%) had stent restenosis while 212 did not. Univariate analysis showed that a family history of CHD, history of type 2 diabetes, hypertension, smoking, and drinking, discontinuation of aspirin, use of conventional dose statins, calcified lesions, ≥ 3 implanted stents, stent length ≥ 30 mm, stent diameter < 3 mm, and tandem stent increased the risk of restenosis. The incidence of restenosis was higher in the stent group than that in the nonstent group (P < .05). There were no significant differences in the blood lipid level, left ventricular ejection fraction, clopidogrel/ticagrelor or beta-blocker withdrawal, location of culprit vessels, and thrombotic lesions between the 2 groups (P > .05). Multivariate logistic regression analysis showed that family history of CHD, history of type 2 diabetes, hypertension, smoking, and drinking, aspirin withdrawal, use of conventional doses of statins, calcified lesions, ≥ 3 implanted stents, stent length ≥ 30 mm, stent diameter < 3 mm, and tandem stenting were risk factors for ISR within 2 years after PCI. A family history of CHD, history of type 2 diabetes, hypertension, smoking, and drinking, discontinuation of aspirin, use of conventional dose statins, calcified lesions, ≥ 3 stent implantations, stent length ≥ 30 mm, stent diameter < 3 mm, and tandem stenting are risk factors for ISR within 2 years after PCI in patients with CHD.Copyright © 2022 the Author(s).
