This substudy of the ALONE-AF trial evaluated the cognitive effects of oral anticoagulant (OAC) discontinuation in patients aged 19-80 years without atrial fibrillation recurrence after catheter ablation. The randomized controlled trial found no significant difference in cognitive decline between those who discontinued OAC and those who continued, with a between-group difference in MoCA score change of 0.1.
Key findings
- Mean total MoCA score increased from 24.4 to 25.0 in the no-OAC group.
- Mean total MoCA score increased from 24.2 to 24.9 in the OAC group.
- No significant difference in cognitive score change between no-OAC and OAC groups (P = .759).
Why it matters
Understanding the cognitive implications of OAC therapy discontinuation in patients post-ablation is crucial for managing long-term care and stroke risk. This study suggests that discontinuation may not adversely affect cognitive function in this population.
