Avoid aspirin in atrial fibrillation, cardiologist urges

Aspirin continues to be misused as thromboprophylaxis in atrial fibrillation (AF) despite being neither effective nor safe, a leading Sydney cardiologist says.

The default strategy should be to offer all patients with AF either warfarin or a newer oral anticoagulant (NOAC) unless they are low risk, says Professor Ben Freedman, from the Heart Research Institute at the University of Sydney’s Charles Perkins Centre.
