Anticoagulation for New-Onset Post-Operative Atrial Fibrillation After CABG
Not Recruiting
Trial ID: NCT04045665
Purpose
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.

Eligibility
Inclusion Criteria:
- Patients of age ≥18 years who undergo isolated CABG for coronary artery disease
- POAF that persists for >60 minutes or is recurrent (more than one episode) within 7
days after the index CABG surgery
Exclusion Criteria:
- Clinical history of either permanent, persistent or paroxysmal atrial fibrillation
- Any pre-existing clinical indication for long-term OAC
- Any absolute contraindication to OAC
- Planned use of post-operative dual antiplatelet therapy (DAPT)
a. This includes, but is not limited to, patients with recent PCI with drug-eluting or
bare-metal stent.
- Cardiogenic shock
- Major perioperative complication* occurring between CABG and randomization
a. including, but not limited to, stroke, TIA, MI, major bleeding (BARC type 4
bleeding), severe sepsis, renal failure requiring dialysis, or need for reoperation
due to bleeding (e.g. pericardial tamponade).
- Concomitant left atrial appendage closure during CABG
- Concomitant valve surgery during CABG or prior valve surgery (including aortic,
mitral, tricuspid or pulmonary)
- Concomitant mitral valve annuloplasty during CABG
- Concomitant carotid artery endarterectomy during CABG
- Concomitant aortic root replacement during CABG
- Concomitant surgery for AF during CABG
- Liver cirrhosis or Child-Pugh Class C chronic liver disease
- Pharmacologic therapy with an investigational drug or device within 30-days prior to
randomization or plan to enroll patient in an investigational drug or device trial
during participation in this trial
- Pregnancy at the time of randomization
- Unable or unwilling to provide inform consent
- Unable or unwilling to comply with the study treatment and follow-up
- Existence of underlying disease that limits life expectancy to less than one year
Intervention(s):
drug: Antiplatelet-only strategy
drug: Oral Anticoagulant plus background antiplatelet therapy
