About this study
The primary objective of this study is to evaluate the effectiveness (prevention of thromboembolic events) and safety (major bleeding) of adding oral anticoagulation (OAC) to background antiplatelet therapy in patients who develop new-onset post-operative atrial fibrillation (POAF) after isolated coronary artery bypass graft (CABG) surgery.
All patients with a qualifying POAF event, who decline randomization, will be offered the option of enrollment in a parallel registry that captures their baseline risk profile and their treatment strategy in terms of anticoagulants or antiplatelets received. These patients will also be asked to fill out a brief decliner survey.
Read the detailed description
This is a prospective, multicenter, open-label, randomized trial comparing OAC with no OAC (1:1 ratio) in patients who develop new-onset POAF after CABG. The primary effectiveness endpoint is the composite of death, ischemic stroke, transient ischemic attack (TIA), myocardial infarction (MI), systemic arterial thromboembolism or venous thromboembolism (VTE) at 90 days after randomization. The primary safety endpoint is BARC (Bleeding Academic Research Consortium) grade 3 or 5 bleeding at 90 days after randomization. The overall intent is to evaluate the trade-off in prevention of thromboembolic events versus an increase in bleeding.
Patients will be randomly assigned to the following treatment strategies:
- OAC-based strategy (experimental arm): OAC with vitamin K antagonist (VKA) with international normalized ratio (INR) target 2-3 or any approved direct oral anticoagulant (apixaban, rivaroxaban, edoxaban or dabigatran) in addition to background antiplatelet therapy with aspirin 75-325mg once-daily or a P2Y12-inhibitor (clopidogrel or ticagrelor)
- Antiplatelet-only strategy (control arm): single antiplatelet therapy with aspirin 75-325mg once-daily or a P2Y12-inhibitor (clopidogrel or ticagrelor)
The protocol-specified duration of anticoagulation is 90 days. Patients, who are randomized to the control arm and develop recurrent AF after 30 days, may be crossed-over to an OAC. Accrual is expected to take 60 months. Study follow-up visits will be performed at 90 days and phone follow-up at days 30, 60, and 180 days.
Data for patients enrolled in the registry will be ascertained from the local clinical site via a review of medical records. The baseline risk profile of registry patients (i.e., patients eligible but unwilling to be randomized) will be analyzed and compared to that of patients randomized in the trial. The usage of anticoagulant and antiplatelet therapies in the registry population overall and baseline CHA2DS2-VASC ischemic stroke risk score will also be determined.
Up to 500 patients will also be offered the option to participate in a digital health substudy which includes a wearable heart rhythm monitor device for 30 days post discharge.

What is being measured
The primary outcome is the main question the study is designed to answer.
Composite of death, ischemic stroke, TIA, MI, systemic arterial thromboembolism or venous thromboembolism (DVT and/or PE)
Composite score of death, ischemic stroke, transient ischemic attack (TIA), myocardial infarction (MI), systemic arterial thromboembolism or venous thromboembolism (deep venous thrombosis and/or pulmonary embolism). Composite score calculated by number of events.
Measured: up to 180 days after randomization
Any BARC type 3 or 5
The Bleeding Academic Research Consortium (BARC) - any type 3 or 5 bleeding thrombosis and/or pulmonary.
Type 3: a. Overt bleeding plus hemoglobin drop of 3 to < 5 g/dL (provided hemoglobin drop is related to bleed); transfusion with overt bleeding
- Overt bleeding plus hemoglobin drop < 5 g/dL (provided hemoglobin drop is related to bleed); cardiac tamponade; bleeding requiring surgical intervention for control; bleeding requiring IV vasoactive agents
- Intracranial hemorrhage confirmed by autopsy, imaging, or lumbar puncture; intraocular bleed compromising vision. type 5: a. Probable fatal bleeding
- Definite fatal bleeding (overt or autopsy or imaging confirmation)
Measured: 90 days after randomization
Secondary outcomes (11)
Net clinical benefit (NCB)
Defined as the integration of the trial's primary effectiveness and safety endpoint to capture overall risk and benefit of anticoagulation. NCB will be assessed as a two-dimensional outcome with the observed NCB plotted versus effectiveness and safety, and a curve drawn. the confidence intervals will be compared to this curve.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The primary objective of this study is to evaluate the effectiveness (prevention of thromboembolic events) and safety (major bleeding) of adding oral anticoagulation (OAC) to background antiplatelet therapy in patients who develop new-onset post-operative atrial fibrillation (POAF) after isolated coronary artery bypass graft (CABG) surgery.
All patients with a qualifying POAF event, who decline randomization, will be offered the option of enrollment in a parallel registry that captures their baseline risk profile and their treatment strategy in terms of anticoagulants or antiplatelets received. These patients will also be asked to fill out a brief decliner survey.
Detailed description
This is a prospective, multicenter, open-label, randomized trial comparing OAC with no OAC (1:1 ratio) in patients who develop new-onset POAF after CABG. The primary effectiveness endpoint is the composite of death, ischemic stroke, transient ischemic attack (TIA), myocardial infarction (MI), systemic arterial thromboembolism or venous thromboembolism (VTE) at 90 days after randomization. The primary safety endpoint is BARC (Bleeding Academic Research Consortium) grade 3 or 5 bleeding at 90 days after randomization. The overall intent is to evaluate the trade-off in prevention of thromboembolic events versus an increase in bleeding.
Patients will be randomly assigned to the following treatment strategies:
- OAC-based strategy (experimental arm): OAC with vitamin K antagonist (VKA) with international normalized ratio (INR) target 2-3 or any approved direct oral anticoagulant (apixaban, rivaroxaban, edoxaban or dabigatran) in addition to background antiplatelet therapy with aspirin 75-325mg once-daily or a P2Y12-inhibitor (clopidogrel or ticagrelor)
- Antiplatelet-only strategy (control arm): single antiplatelet therapy with aspirin 75-325mg once-daily or a P2Y12-inhibitor (clopidogrel or ticagrelor)
The protocol-specified duration of anticoagulation is 90 days. Patients, who are randomized to the control arm and develop recurrent AF after 30 days, may be crossed-over to an OAC. Accrual is expected to take 60 months. Study follow-up visits will be performed at 90 days and phone follow-up at days 30, 60, and 180 days.
Data for patients enrolled in the registry will be ascertained from the local clinical site via a review of medical records. The baseline risk profile of registry patients (i.e., patients eligible but unwilling to be randomized) will be analyzed and compared to that of patients randomized in the trial. The usage of anticoagulant and antiplatelet therapies in the registry population overall and baseline CHA2DS2-VASC ischemic stroke risk score will also be determined.
Up to 500 patients will also be offered the option to participate in a digital health substudy which includes a wearable heart rhythm monitor device for 30 days post discharge.
