Why the study?
What are the predictors of high INR variability in patients with atrial fibrillation under warfarin therapy?
What are the predictors of high INR variability in patients with atrial fibrillation under warfarin therapy?
Identifying determinants of INR variability can help clinicians predict unstable warfarin control in patients with atrial fibrillation.
May inform INR variability risk stratification in warfarin-treated AF; leaves open whether targeting predictors improves outcomes.
