1. In Chinese patients with atrial fibrillation,
the presence of ≥5 cerebral microbleeds on magnetic resonance imaging is
associated with an increased risk of warfarin-related intracerebral
haemorrhage.
2. Evaluation of cerebral microbleeds in patients with atrial fibrillation may help identify patients at higher risk of warfarin-related intracerebral haemorrhage, who may benefit from alternative treatment options with lower bleeding risk.
