Abstract
Objective To investigate relationship between stent length and in-stent restenosis(ISR)after percutaneous coronary artery stent implantation in acute coronary syndrome(ACS).Methods A retrospective analysis was performed for 206 patients who received stent implantation in ACS in our hospital from January 2020 to December 2021,and coronary angiography was followed up 12 months after stent implantation,and they were divided into ISR group and non-ISR group according to the contrast situation.Logistic regression models and area under the ROC curve were used to determine the role of stent length in predicting ISR.Results 62 patients(30.1％)had ISR and 144 cases(69.9％)had non-ISR 12 months after emergency PCI and stent im-plantation with ACS.The stenosis of anterior descending artery,circumflex artery and right coronary artery lesions in the ISR group was higher than that in the non-ISR group,and the stent length was significantly higher than that in the non-ISR group(P＜0.05).Multivariate Logistics regression analysis showed that stent length and stenosis of anterior descending artery and circumflex lesions were associated with the risk of ISR.The AUC of stent length predicted ISR was 0.701(95％CI 0.594～0.803),and the AUC of stent length,anterior descending artery stenosis,and circumflex artery stenosis was 0.860(95％CI 0.763～0.957).The sensitivity and specificity of stent length in predicting ISR risk were 0.742,the specificity was 0.528,and the optimal cut-off value was 29 mm.Conclusion Stent length would be correlated with ISR and would have a certain predictive value for the risk of ISR after ACS stent implantation.关键词
