New Atrial Fibrillation (AF) Stroke Risk Factors Reveal That More Should Be on Coumadin or Warfarin, Especially Women

This very important story may change how afib patients and their doctors decide if they should be on anticoagulant medications (blood thinners), such as Coumadin or warfarin.
The CHADS 2 scoring system is how doctors now decide who should be on Coumadin or warfarin to avoid strokes, but a newly-published study adds new stroke risk factors that are not considered in CHADS 2.
These new risk factors, including being female, having heart or vascular disease, and being age 65 or greater (CHADS 2 uses 75 or greater), have been incorporated in a scoring system called the “2009 Birmingham Schema” (CHA 2 DS 2 -VASc). This new approach enhances the existing CHADS 2 system, giving two points to definitive stroke risk factors and one point to combination stroke risk factors.
