Abstract：【Objective】To analyze the influencing factors of restenosis after coronary stent implantation by percutaneous coronary intervention (PCI) in elderly patients with coronary heart disease in Hezhou area.【Methods】A total of 937 elderly patients with coronary heart disease in Hezhou area receiving treatment at the People's Hospital of Hezhou City from June 2012 to January 2017 were the subjects of this study. Clinical data of all patients were collected to analyze the related factors of restenosis after coronary stent implantation by PCI in senior coronary heart disease.【Results】A total of 47 cases of stent restenosis occurred in the 937 patients with coronary stents, accounting for 5.02% of the total study group. Smoking history, hypertension, diabetes, LDL-C≥2.6mmol/L, stent diameter<3.5mm, the number of stent ≥ 2 pieces, stent length≥30mm, tandem stent, withdrawl of aspirin, family history of coronary heart disease, no high-dose statins were independent risk factors for restenosis after coronary stenting by PCI in elderly patients with coronary heart disease (P<0.05).【Conclusion】The factors that affect the restenosis after coronary stenting in senior patients in Hezhou are complex and need to be combined with the basic disease and coronary angiography results to reasonably assess the risk factors. In cases where there is a high risk of coronary stent restenosis, it is necessary to increase the secondary prevention of coronary heart disease with drug treatment regimens, strive to reduce the occurrence of coronary stent restenosis and improve the prognosis of senior patients with coronary heart disease.
