Long-term persistence on warfarin in patients with non-valvular atrial fibrillation is essential to minimise thromboembolic complications, especially ischaemic stroke. This study examines persistence in Australian patients with presumed atrial fibrillation newly prescribed warfarin. ⋯ There is significant discontinuation of warfarin therapy. When due to non-compliance, an opportunity for stroke prevention is being lost.
