Why the study?
AF causes a major burden on quality of life, including sleep quality, but data describing sleep quality, its predictors, and its association with arrhythmia symptoms in this population were needed.
Poor sleep quality is highly prevalent among patients with atrial fibrillation and is independently predicted by symptom burden, caffeine intake, and COPD.
No takes yet. Share an insight, caveat, or question.
AF patients with multiple or bothersome symptoms warrant sleep assessment; observational data leaves open causal links and intervention effects.
Noureddine et al. (2025) studied this question.
