Day-to-day measurement of physical activity and risk of atrial fibrillation.

Aims: The aim of this study was to investigate the association between within-individual changes in physical activity and onset of atrial fibrillation (AF).

Methods And Results: A total of 1410 participants from the general population (46.2% women, mean age 74.

Atrial fibrillation burden and cognitive decline in elderly patients undergoing continuous monitoring.

Aims: To study the relationship between subclinical atrial fibrillation (AF) and changes in cognitive function in a large cohort of individuals with stroke risk factors.

Methods: Individuals with no prior AF diagnosis but with risk factors for stroke were recruited to undergo annual cognitive assessment with the Montreal Cognitive Assessment (MoCA) along with implantable loop recorder (ILR) monitoring for AF for 3 years. If AF episodes lasting ≥6 minutes were detected, oral anticoagulation (OAC) treatment was initiated.
