Background. In-stent restenosis (ISR) remains a common problem following percutaneous coronary intervention (PCI). However, the best treatment strategy remains uncertain. There is some controversy over the efficacy of drug-eluting balloons (DEBs) and second-generation drug-eluting stents (DESs) for treating ISR. Methods. A meta-analysis was used to compare the efficacy of the DEB and second-generation DES in the treatment of ISR. The primary endpoint is the incidence of target lesion revascularization (TLR). The secondary endpoint is the occurrence of target vessel revascularization (TVR), myocardial infarction (MI), all-cause death (ACM), cardiac death (CD), major adverse cardiac events (MACEs), minimum luminal diameter (MLD), late luminal loss (LLL), binary restenosis (BR), and percent diameter stenosis (DS%). Results. A total of 12 studies (4 randomized controlled trials and 8 observational studies) including 2020 patients with a follow-up of 6–25 months were included in the present study. There was a significant difference in the MLD between the two groups during follow-up (P=0.007, RR = 0.23, and 95% CI: 0.06–0.4 mm). There was no significant difference in LLL, BR, or DS% and the overall incidence of MACEs between the two groups. Subgroup analysis showed no significant difference in the incidence of primary and secondary endpoints when considering RCTs or observational studies only. Conclusions. The efficacy of the DEB and second-generation DES in the treatment of ISR is comparable. However, our results need further verification through multicenter randomized controlled trials.

Abstract Background: Recently, drug-eluting stents have been widely adopted rather than bare-metal stents in patients on chronic hemodialysis (HD) based on the extrapolation of data from patients on non-HD. However, whether DES implantation is associated with a reduced rate of in-stent restenosis (ISR) is unclear. We investigated the incidence of ISR and its predictors in patients on HD after drug-eluting stent implantation.Methods and Results: We analyzed 194 consecutive patients (331 lesions) on HD who underwent follow-up angiography after drug-eluting stent implantation. ISR was observed in 74 lesions (22.4%). Angiographically, the relative incidence of AHA/ACC type C lesion was increased (47% vs. 32%; P=0.043), the minimal lumen diameter (MLD) before DES implantation was smaller (0.82±0.49 vs. 0.97±0.45mm; P<0.01) and the lesion length (LL) was increased (30.2±16.1 vs. 24.4±12.1mm; P=0.023) in lesions with ISR compared to those without ISR. The rate of rotational atherectomy use was also increased in lesions with ISR compared to those without ISR (50% vs. 25%; P<0.01). In a multivariate analysis, the MLD before drug-eluting stent implantation (odds ratio [OR] =0.50, 95% confidence interval [CI] 0.27-0.91, P=0.024), LL (OR=1.02, 95% CI 1.00-1.04, P=0.030) and the use of rotational atherectomy (OR=2.71, 95% CI 1.55-4.72, P<0.01) were independent predictors of ISR. The incidence of ISR was similar between lesions treated with the first-generation (25.8%) and the second-generation DESs (20.4%).Conclusion: ISR was observed in 74 lesions (22.4%). A small MLD, long LL and the use of rotational atherectomy were independent predictors of ISR after drug-eluting stent implantation in patients on HD. There was no significant difference in ISR rate between the first- and the second-generation drug-eluting stents.
