Key result
Visceral embolic events occur in ~2% of AF patients and carry high mortality with concurrent AMI.
Why the study?
Visceral embolic events in AF represent understudied complications often subsumed within broader systemic embolic categories, with potential risk stratification implications following the introduction of the CHA2DS2-VA score.
Population
329,128 AF patients across 12 studies
Design
Systematic review and meta-analysis

May warrant heightened vigilance for visceral emboli in AF; extends incidence estimates but leaves optimal prevention open.
Visceral embolic events occur in approximately 1-6% of AF patients with high mortality, highlighting the need for enhanced clinical awareness and individualized risk assessment.
Alalwani et al. (2025) studied this question. Visceral embolic events occur in approximately 1.6% of atrial fibrillation patients, with mortality rates ranging from 17% to 64% based on concurrent acute myocardial infarction.
