AI Summary

Atrial fibrillation is the most common irregular heart rhythm and a leading cause of ischemic stroke. Oral anticoagulants such as edoxaban effectively prevent these strokes, but they increase bleeding risk. The risk is especially high for patients who have previously suffered an intracranial hemorrhage, which involves bleeding within or around the brain. Safer stroke‑prevention strategies are therefore needed for this high‑risk group.
