When do I anticoagulate paroxysmal AF?

Base it on CHA₂DS₂-VASc, not the AF pattern: paroxysmal AF carries a stroke risk similar to persistent AF, so don't defer because episodes are brief.1,2

Recommendation

Anticoagulate at CHA₂DS₂-VASc ≥2 (men) or ≥3 (women); prefer a DOAC over warfarin for nonvalvular AF.3
