Previous study showed that triple antiplatelet, with aspirin, clopidogrel, and cilostazol, significantly reduced stent thrombosis and myocardial infarction after DES implantation in a broad range of population. This study evaluate efficacy and safety of triple anti-platelet therapy compared with dual antiplatelet therapy in patients treated with DES for coronary artery disease. METHODS This prospective, double-blind, multicenter, randomized, phase 4 study was conducted in 9 cardiac centers in Korea between September 2011 and January 2014. Patients (n ¼ 404) were randomly assigned to triple (aspirin, clopidogrel, and cilostazol, triple group: n ¼ 202) or dual antiplatelet therapy (aspirin and clopidogrel and placebo, dual group: n ¼ 202). Primary endpoint was composite of any death, myocardial infarction (MI), ischemic stroke, or target vessel revascularization (major adverse cardiac and cerebrovascular event, MACCE) for 12 months. RESULTS The two groups had similar about In addition, target vessel revascularization (0.9% vs 5.1%, p ¼ 0.015) and target lesion revascularization rate (0.9% vs 4.6%, p ¼ 0.025) of triple group were significantly lower than those of dual group. There was no difference in safety outcome between two groups.

CONCLUSION Triple antiplatelet therapy after DES implantation tends to improve clinical outcome through reduction of target vessel revascularization.

Weiner Cardiovascular Institute at Mount Sinai School of Medicine, New York, New York, United States BACKGROUND The optimal antithrombotic regimen after PCI for patients with atrial fibrillation(AF) is unclear. Availability of direct oral anticoagulants (DOAC) might change the treatment strategy for these patients. We investigated the use of antithrombotic regimens with warfarin and DOAC in a real world PCI population. METHODS We analyzed data from 1269 patients with history of AF treated with PCI at a tertiary care Hospital in New York City from 2010 to 2015. Therapies were defined as: Dual antiplatelet therapy (DAPT); Dual¼ASA or P2Y12 inhibitor + warfarin (Warf) or DOAC; triple¼ DAPT + Warf or DOAC. RESULTS The prescription of DAPT, dual and triple at discharge is in Fig.A. Overall for both dual and triple, the use of Warf and DOAC was 65% and 35% respectively. However there was a progressive increase in the use of DOAC over time Fig. B. Patients prescribed DOAC had lower baseline eGFR and CHADS2 thromboembolic risk score than Warf patients (2.501.12 vs 2.691.13, p¼0.05) but a similar ATRIA bleeding risk score (3.672.14 vs 3.882.23, p¼0.26). The rate of periprocedural complications (4.4%vs3.3%, p¼0.52) and 30-day readmission (5.8%vs5.3%, p¼0.77) did not differ significantly between DOAC and Warf. At 1 year the adjusted risk of all-cause mortality (0.93 [0.48-1.80]) and MACE (death, myocardial infarction or target vessel revascularization)(1.27[0.81-2.01]) were similar between DAOC and Warf.
CONCLUSION Despite the lack of data from large randomized trials the use of DOAC in PCI patients with AF is increasing. DOAC use was not associated with worse short and long term ischemic clinical outcomes compared to Warf.
