Objectives  Coronary artery disease (CAD) is a common cardiac disease with high morbidity and mortality, and triple-vessel disease (TVD) is a severe type of CAD. This study investigated risk factors for revascularization and in-stent restenosis (ISR) in TVD patients who underwent second-generation drug-eluting stent implantation.    Methods  A retrospective clinical study was conducted, and 246 triple-vessel disease (TVD) patients with 373 vessels after second-generation drug-eluting stent (DES) implantation who received follow-up coronary angiography (CAG) were consequently enrolled. According to the follow-up angiography, patients were categorized into the revascularization group and nonrevascularization group as well as the in-stent restenosis (ISR) group and non-ISR group. Univariate and multivariate logistic regression analyses were used to identify risk factors for revascularization and ISR. Receiver operating characteristic (ROC) curve with area under the curve (AUC) analysis was performed to assess the predictive power of these risk factors.    Results  In the median follow-up period of 28.0 (14.0, 56.0) months, 142 TVD patients (57.7%) with 168 vessels underwent revascularization, and ISR occurred in 43 TVD patients (17.5%) with 47 vessels after second-generation DES implantation. Compared to the nonrevascularization group, the revascularization group presented with an increased rate of current smoking and higher levels of TC, LDL-C, HDL-C, non-HDL-c, ApoB, neutrophils, and Hs-CRP as well as a longer follow-up of months but with a lower level of HDL-C. In addition, patients in the ISR group had an older age, longer follow-up (months) and elevated rates of current smoking and stage 4–5 chronic kidney disease (CKD4-5). In multivariate analysis, current smoking and higher non-HDL-c were independent risk factors for revascularization. In addition, older age, current smoking and CKD4-5 were considered independent risk factors for ISR. Importantly, the receiver operating characteristic curve showed that non-HDL-C and age displayed predictive power for revascularization and ISR, respectively.    Conclusion  Current smoking is an independent risk factor for both revascularization and in-stent restenosis. Higher non-HDL-c is independently related to revascularization; moreover, increased age and CKD4-5 are potential risk factors for ISR in TVD patients after second-generation drug-eluting stent implantation.
