Compare: stroke vs bleeding

Side-by-side CHA₂DS₂-VASc and HAS-BLED — the standard AFiB anticoagulation decision.

In atrial fibrillation, the decision to start oral anticoagulation balances stroke risk (CHA₂DS₂-VASc) against bleeding risk (HAS-BLED). A high HAS-BLED score is rarely a reason to withhold anticoagulation; it's a flag for closer monitoring and reversible-factor review.
