Dabigatran compared with warfarin in patients with atrial fibrillation and previous transient ischaemic attack or stroke: a subgroup analysis of the RE-LY trial.
Summary
Background
In the Randomised Evaluation of Long-Term Anticoagulation Therapy (RE-LY) trial, dabigatran reduced occurrence of both stroke and haemorrhage compared with warfarin in patients who had atrial fibrillation and were at increased risk of stroke. We aimed to assess the effects of dabigatran compared with warfarin in the subgroup of patients with previous stroke or transient ischaemic attack.
