Key result
The CHA2DS2-VASC score markedly increased the proportion of atrial fibrillation ablation patients recommended for definite oral anticoagulation compared to the CHADS2 score (50.2% vs 23.0%).
Why the study?
Does the use of the CHA2DS2-VASC score compared to the CHADS2 score change oral anticoagulation recommendations in patients undergoing atrial fibrillation ablation?
Cohort (n=1,411)
Does the use of the CHA2DS2-VASC score compared to the CHADS2 score change oral anticoagulation recommendations in patients undergoing atrial fibrillation ablation?
Absolute Event Rate: 50.2% vs 23%
The CHA2DS2-VASC score significantly increases the proportion of AF ablation patients recommended for oral anticoagulation compared to the CHADS2 score, primarily driven by age 65-74 and female gender.
No takes yet. Share an insight, caveat, or question.
May increase OAC use in AF ablation patients; leaves open net benefit versus CHADS2-based decisions.
Winkle et al. (2013) conducted a cohort in Atrial fibrillation (n=1,411). CHA2DS2-VASC score vs. CHADS2 score was evaluated on Recommendation for DEFINITE-OAC. The CHA2DS2-VASC score markedly increased the proportion of atrial fibrillation ablation patients recommended for definite oral anticoagulation compared to the CHADS2 score (50.2% vs 23.0%).
