Anticoagulation for Stroke Prevention in Atrial Fibrillation

This study is looking at whether taking certain blood thinners (non-vitamin K oral anticoagulants, or NOACs, like edoxaban or apixaban) can prevent strokes and other heart-related problems in people who have had temporary episodes of atrial fibrillation (an irregular heartbeat) due to stress. You might be able to join if you are 55 or older and have had at least one episode of atrial fibrillation after certain surgeries or other stressful events. The researchers will compare people who take these blood thinners to those who do not, to see if the blood thinners reduce the risk of non-hemorrhagic stroke (stroke not caused by bleeding) or other serious cardiovascular events like heart attacks or death.

Study design
This is a multinational, randomized, open-label study comparing non-vitamin K oral anticoagulants (NOACs) to no oral anticoagulation. It plans to enroll 2270 participants.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for the duration of the study, until the last participant has been followed for 24 months.
