Background: Differences in the impact of the 1- or 2-stent strategy in similar coronary bifurcation lesion conditions are not well understood. This study investigated the clinical outcomes and its predictors between 1 or 2 stents in propensity score-matched (PSM) complex bifurcation lesions.Methods and Results: We analyzed the data of patients with bifurcation lesions, obtained from a multicenter registry of 2,648 patients (median follow up, 53 months). The patients were treated by second generation drug-eluting stents (DESs). The primary outcome was target lesion failure (TLF), composite of cardiac death, target vessel myocardial infarction (TVMI), and ischemia-driven target lesion revascularization (TLR). PSM was performed to balance baseline clinical and angiographic discrepancies between 1 and 2 stents. After PSM (N=333 from each group), the 2-stent group had more TLRs (hazard ratio [HR] 3.14, 95% confidence interval [CI] 1.42–6.97, P=0.005) and fewer hard endpoints (composite of cardiac death and TVMI; HR 0.44, 95% CI 0.19–1.01, P=0.054), which resulted in a similar TLF rate (HR 1.40, 95% CI 0.83–2.37, P=0.209) compared to the 1-stent group. Compared with 1-stent, the 2-stent technique was more frequently associated with less TLF in the presence of main vessel (pinteraction=0.008) and side branch calcification (pinteraction=0.010).Conclusions: The 2-stent strategy should be considered to reduce hard clinical endpoints in complex bifurcation lesions, particularly those with calcifications.

Background: The clinical effect of, and additive measures to overcome the possible inhibitory calcium channel blocker (CCB)-clopidogrel interaction in Asian patients undergoing percutaneous coronary intervention is unknown. Methods and Results: A total of 900 Korean patients enrolled for the multicenter, prospective, randomized Influence of CILostazol-based triple antiplatelet therapy ON ischemic complication after drug-eluting stenT implantation (CILON-T) trial were divided into 4 groups depending on CCB prescription and type of anti-platelet therapy (dual [DAT] vs. triple [TAT; addition of cilostazol to DAT]) in a 2×2 factorial manner. The primary endpoint was a composite of cardiac death, non-fatal myocardial infarction and ischemic stroke at 6 months after PCI. On-treatment platelet reactivity (OPR) was assessed on VerifyNow P2Y12 assay. Concomitant CCB use increased OPR in the DAT group (mean±SEM: 251.2±7.6 vs. 225.6±5.1; P=0.008), but not in the TAT group (214.5±9.1 vs. 203.4±5.6; P=0.294). Primary endpoint increased by use of CCB in patients with DAT (4.9% vs. 0.9%, P=0.016), but not in those with TAT (0% vs. 1.8%, P=0.346). Addition of cilostazol to DAT reduced OPR and clinical events in patients taking CCB (P=0.007 for P2Y12 reaction units; P=0.027 for thrombotic events). CCB without concomitant cilostazol use was a significant predictor of total thrombotic events. Conclusions: Concomitant use of CCB may weaken the anti-platelet effect of clopidogrel and increase subsequent thrombotic events in Asian subjects. This hazardous CCB-clopidogrel interaction may be overcome by addition of cilostazol.
