Abstract | OBJECTIVE: To describe the long-term antithrombotic management patterns (AMPs) and clinical outcomes of Chinese patients with acute coronary syndrome (ACS). METHODS: This was an observational, multicenter, longitudinal cohort extension study of Chinese patients who had completed the EPICOR Asia 2-year follow-up study post-hospitalization for an ACS event. Changes in AMP and clinical outcomes for up to 5 years post-ACS event were evaluated. RESULTS: Overall, 2334 patients with ACS were enrolled at 49 sites. The mean age was 61.6 years and 76.3% were men. By study end, 2093 patients completed the 3-year follow-up. At baseline (2 years post-ACS event), 72.4% of patents received one antiplatelet (AP) medication, with aspirin being the preferred one. A small proportion of patients (21.5%) was treated with two or more APs (2+ AP), and even fewer patients (6.1%) did not receive any AP medication at baseline. Upon study completion, the proportion of patients without AP therapy increased to 13.6%, while the percentage of patients on one AP and 2+ AP decreased to 69.3% and 17.1%, respectively. Numerically, a higher incidence of clinical events (composite of all-cause mortality, myocardial infarction, stroke) was observed for the 2+ AP (13.2%) subgroup than for the no AP (10.5%) and one AP (8.6%) subgroups. Furthermore, the 2+ AP subgroup exhibited the greatest number of bleeding events, outpatient visits, and hospitalization rates. Unlike myocardial infarction or stroke, bleeding events prompted an adjustment in AMP. CONCLUSION: Most patients in China received at least one AP medication up to 5 years after an ACS event.
