Prevalence of asymptomatic atrial fibrillation and risk factors associated with asymptomatic status: a systematic review and meta-analysis
- Systematic review and meta-analysis
- random-effects meta-analysis
- double-independent study selection
Authors' conclusion
Asymptomatic AF was estimated around 27%, with large variability depending on the prevalence of risk factors associated with asymptomatic status. Asymptomatic individuals had distinct characteristics compared to symptomatic patients, regardless of symptoms' assessment methods and rhythm/rate control interventions.
