Background: Cardiovascular diseases account for approximately half of all deaths in Asia. The present analysis aimed to evaluate characteristics, antithrombotic management patterns (AMPs), and outcomes in patients with acute coronary syndrome (ACS) who underwent in-hospital percutaneous coronary intervention (PCI) and survived to hospital discharge, using data from the EPICOR Asia registry (NCT01361386)., Methods: Two-year post-discharge follow-up data were analyzed from 8757 ACS PCI patients from EPICOR Asia (218 centers, eight countries). Major adverse cardiovascular events (MACE; death, non-fatal myocardial infarction [MI], non-fatal ischemic stroke), PCI characteristics, and AMPs were recorded. For MACE, time - to - event was analyzed using Cox regression., Results: Primary PCI was performed in 62.0% of ST-segment elevation MI (STEMI), 38.7% of non-STEMI (NSTEMI), and 24.2% of unstable angina (UA) patients. At 12 months, 88.1% of patients were on dual antiplatelet therapy (DAPT), with no differences by index event. Most (61.5%) still received DAPT at 2 years. Two-year incidences of mortality, composite MACE, and bleeding were 3.6%, 6.2%, and 6.6%, respectively. Risk of death and MACE was increased with STEMI and NSTEMI vs. UA. Patients from East Asia showed lower mortality and more bleeding vs. Southeast Asia/India., Conclusions: Many patients in EPICOR Asia underwent PCI and received DAPT up to 2 years post-discharge. These real-world findings improve our understanding of AMP impact on outcomes in Asian patients with ACS undergoing PCI., Competing Interests: Declaration of competing interest S.Z., W.W., J.P.S.S., H.S.K., S.W.L.L., Y.H., J.Q., and J.G. declare no conflict of interest.

Background:  The ischemic/bleeding risk of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) is still uncertain. We sought to develop a tool to predict ischemic and bleeding events in East Asians receiving 2nd generation drug-eluting stents (DESs) PCI., Methods:  A pooled cohort of 13,172 East Asian patients receiving PCI with 2nd generation DES (the Grand DES cohort) was analyzed to develop a scoring system. A net score was calculated by subtracting the bleeding score from the ischemic score. External validation was performed in the HOST-ASSURE and NIPPON trials., Results:  Among the total population, ischemic and bleeding events occurred in 195 patients (1.5%) and 166 patients (1.3%), respectively. The score to predict ischemic events included previous myocardial infarction (MI) or PCI, presentation as acute MI, anemia, stent diameter < 3 mm, and total stent length of ≥30 mm, while that for bleeding events included older age, low creatinine clearance, and anemia. C-statistics of the ischemic and bleeding model was 0.708 and 0.665, respectively. Patients with a net score of ≥1 had a higher ischemic risk compared with bleeding risk, and patients with a net score of ≤-1 had a higher bleeding risk compared with ischemic risk. The validation cohort showed a C-statistic of 0.647 for ischemic events and 0.633 for bleeding events., Conclusion:  We developed a tool to predict ischemic and bleeding events in East Asian patients received PCI with 2nd generation DES. This system can be used to assess clinical event risks, and to determine the adequate duration of DAPT in East Asians., Competing Interests: Dr. Nakamura reports grants and other from Terumo Corporation, Sanofi, and Daiichi Sankyo, outside the submitted work., (Georg Thieme Verlag KG Stuttgart · New York.)
