Preceding Night Sleep Quality and Atrial Fibrillation Episodes in the I-STOP-AFIB Randomized Trial
Primary result · Self-reported AF episode next day, per worse sleep qualityResult — go to the resultOdds ratio 1.15 95% CI 1.10–1.20Authors' conclusion
Poor sleep was associated with an immediately heightened risk for self-reported AF episodes, and a dose-response relationship existed such that progressively worse sleep was associated with longer episodes of AF the next day.
Study context
- Population
- Patients with symptomatic paroxysmal atrial fibrillation (AF)15,755 days of data
- Participants
- 419 patients
- Comparison
- Worse vs better preceding-night sleep quality
- Primary endpoint
- Self-reported AF episode the next day
