Arrhythmias & electrophysiologyCohort study
Atrial fibrillation and risk of sudden cardiac arrest in young adults
- Retrospective cohort study
- nationwide
Authors' conclusion
Atrial fibrillation was associated with a significantly higher risk of SCA developing in healthy young adults.
Study context
- Population
- Young adults aged 20–39 years undergoing health check-ups 2009–2012, South Korean nationwide healthcare database
- Participants
- 6,345,162 adults
- Exposure
- Atrial fibrillation (AF) vs no AF
- AFn = 5,875
- Outcome
- Sudden cardiac arrest (SCA)
- Follow-up
- Mean 9.4 years
Main finding
SCA
Adjusted hazard ratio
2.96
95% CI 1.99–4.41
P < 0.001
By group
AF vs No AF
adjusted HR 2.96 (95% CI 1.99–4.41); P < 0.001
As reported in the abstract
Observational data: associations, not effects.
Further findings
Sudden cardiac arrest (SCA), incident vs prevalent AF
- Both incident and prevalent AF associated with increased SCA risk, no significant difference between the two
