Aspirin and secondary stroke prophylaxis in NRAF

Authoring team

Stroke or TIA in patients with non rheumatic atrial fibrilation in whom intracranial haemorrhage has been excluded should be given aspirin:

  • in NRAF aspirin prevents 40 vascular events per 1000 patient years of treatment (1).
  • definitive anti-platelet therapy should be commenced at 2 weeks post symptoms

Anticoagulation should be introduced subsequently:

  • in NRAF anticoagulation prevents 90 vascular events per 1000 patient years of treatment (1).
