Abstract Objective: To investigate the influence of Logistic regression analysis on the related factors of in-stent restenosis (ISR) in patients with coronary atherosclerotic heart disease (CHD) after stent implantation. Methods: The clinical data of 105 patients with CHD who underwent stent implantation were retrospectively analyzed. According to the occurrence of ISR after stent implantation, the related factors affecting the occurrence of ISR after stent implantation were analyzed by single factor and multi-factor logistic regression. Results: Among 105 patients with CHD, there were 19 cases of ISR with the incidence 18.10% after operation. Univariate analysis showed that the incidence of ISR in patients with family history of CHD, diabetes mellitushistory, hypertensionhistory, smoking history, stent ≥ 3 pieces, stent length ≥ 30 mm, stent diameter < 3.00 mm, tandem stent, low-density lipoprotein-cholesterol (LDL-C) ≥ 3.37 mmoL/L, routine dosage of statins and discontinuation of aspirin were higher than those without family history of CHD, no diabetes mellitus history, nohypertensionhistory, nosmokinghistory, stent < 3 pieces, stent length < 30 mm, stent diameter < 3.00 mm, noseries stent, LDL-C < 3.37 mmoL/L, high dose of statins, no discontinuation of aspirin (P<0.05). Multivariate logistic regression analysis showed that family history of CHD, history of diabetes mellitus, history of hypertension, smoking history, stent ≥ 3 pieces, stent length ≥ 30 mm, stent diameter < 3.00 mm, tandem stent, LDL-C ≥ 3.37 mmoL/L, routine dosage of statins and discontinuation of aspirin were independent risk factors for coronary ISR in patients with CHD after stent implantation (P<0.05). Conclusion: There are many factors influencing the occurrence of ISR in patients with CHD after stent implantation. Therefore, it is necessary to evaluate the factors reasonably in clinic, and to improve the prognosis of patients with possible ISR in time and with emphasis on the treatment of patients with underlying diseases and the results of coronary angiography.
