Non-vitamin K Antagonist Oral Anticoagulant After Acute Coronary Syndrome: Is There a Role?

Despite dual antiplatelet therapy (DAPT) including potent P2Y12 inhibitors, recurrent ischaemic events occur in a significant number of patients after acute coronary syndrome (ACS), warranting new antithrombotic strategies. Combinations of non-vitamin K antagonist oral anticoagulant (NOAC) with antiplatelet therapy have been tested in several large phases II and III randomised trials. Overall, current evidence suggests that the use of NOACs on top of DAPT after ACS reduces the rate of recurrent ischaemic events, albeit at the price of increased risk for major bleeding. In the particular field of patients with ACS and atrial fibrillation, NOACs may be associated with reduced bleeding complications compared with vitamin K antagonist. Further randomised trials evaluating low-dose NOAC combined with single antiplatelet therapy are warranted.
