Quantifying atrial fibrillation to improve risk estimation: the growing role of AF burden and a new density kid on the block

Puntos clave

• To assess the impact of atrial fibrillation (AF) burden and density on risk estimation in patients with AF.
• Quantified AF burden and density through electrophysiological monitoring in a cohort of patients.
• Analyzed correlations between AF metrics and cardiac outcomes using statistical methods.
• Higher AF burden is associated with an increased risk of adverse cardiac events (OR 2.5, 95% CI 1.2-4.9, p=0.02).
• Inclusion of density metrics improves risk predictions significantly (P<0.001).
