Design outcomes

Primary

MeasureTime frame
Main Objective: To determine the most effective and safe antithrombotic strategy to prevent the composite outcome of symptomatic deep vein thrombosis, pulmonary embolism, other venous thromboembolism, ischemic stroke, myocardial infarction, other arterial thromboembolism, and all-cause mortality by 30 days following discharge from the hospital.;Secondary Objective: To determine the most effective and safe antithrombotic strategy on (1) the endpoint of venous thromboembolism (inclusive of symptomatic deep vein thrombosis, pulmonary embolism, other venous thromboembolism) by 30 days in the study population; (2) the endpoint of arterial thromboembolism (inclusive of ischemic stroke, myocardial infarction, other arterial thromboembolism) by 30 days in the study population; (3) the composite primary outcome by 45 and 90 days following discharge from the hospital;Primary end point(s): First occurrence of any of the components of the composite endpoint of symptomatic deep vein thrombosis, pulmonary embolism, other venous thromboembolism, ischemic stroke, myocardial infarction, other arterial thromboembolism, and all-cause mortality by 30 days post-discharge from the hospital;Timepoint(s) of evaluation of this end point: 30 days post-discharge from the hospital

Secondary

MeasureTime frame
Secondary end point(s): (1) Venous thromboembolism (inclusive of symptomatic DVT of the upper or lower extremities, symptomatic and/or clinically relevant PE, and other symptomatic venous thrombosis, including cerebral sinus and splanchnic vein thrombosis) by 30 days post-discharge from the hospital; (2) Arterial thromboembolism (inclusive of symptomatic ischemic stroke, myocardial infarction, and other symptomatic arterial thromboembolic events) by 30 days post-discharge from the hospital; (3) the composite primary endpoint by 45 days and 90 days post-discharge from the hospital;Timepoint(s) of evaluation of this end point: (1) 30 days post-discharge from the hospital (2) 30 days post-discharge from the hospital (3) 45 days and 90 days post-discharge from the hospital
