  "abstract": "Objective: To investigate the association between rivaroxaban combined with clopidogrel therapy and thrombotic risk, platelet activation, myocardial injury biomarkers, and clinical outcomes in patients with coronary artery ectasia (CAE).\n\nMethods: This single-center retrospective cohort study included 158 consecutive patients with CAE diagnosed by coronary angiography between June 2023 and June 2025. Patients receiving clopidogrel alone or rivaroxaban plus clopidogrel were compared. A 1:1 nearest-neighbor propensity score matching method was applied, generating 70 matched pairs. Thrombotic risk markers, including D-dimer (D-D), thrombin-antithrombin complex (TAT), and von Willebrand factor (vWF), platelet activation parameters [ADP-induced platelet aggregation rate (ADP-PAg) and CD62P], thromboelastography parameters [maximum amplitude (MA) and reaction time (R)], and myocardial injury-related biomarkers [high-sensitivity cardiac troponin T (hs-cTnT), creatine kinase-MB (CK-MB), heart-type fatty acid-binding protein (H-FABP), and N-terminal pro-B-type natriuretic peptide (NT-proBNP)] were evaluated at baseline and 6 months. Clinical outcomes, including thrombotic-related adverse cardiovascular events and bleeding events, were recorded during 12 months of follow-up.\n\nResults: After propensity score matching, baseline characteristics were well balanced between groups. At 6 months, patients receiving rivaroxaban plus clopidogrel showed lower levels of D-D, TAT, vWF, ADP-PAg, CD62P, MA, hs-cTnT, CK-MB, H-FABP, and NT-proBNP, as well as prolonged R values, compared with those receiving clopidogrel alone (all P &lt; 0.05). During follow-up, thrombotic-related adverse cardiovascular events occurred less frequently in the combination therapy group than in the clopidogrel group (7.14% vs. 20.00%, P = 0.027). Minor bleeding events were numerically higher in the combination therapy group (17.14% vs. 10.00%, P = 0.218), while no intracranial or fatal bleeding events occurred.\n\nConclusion: Among patients with CAE, rivaroxaban combined with clopidogrel was associated with more favorable changes in coagulation activation, platelet activity, myocardial injury biomarkers, and thrombotic-related clinical outcomes compared with clopidogrel alone. These findings suggest that combined anticoagulant and antiplatelet therapy may represent a potential strategy for selected high-risk patients with CAE. Further multicenter prospective studies are required to confirm these observations.",
