PMID 29271795WHAT IT FOUND
Physical exercise and psychoeducational consultations added to usual care did not improve sleep quality after atrial fibrillation ablation.
Poorer sleep was associated with more AF symptoms and higher anxiety or depression scores.
Key findings
01Physical exercise and psychoeducational consultations added to usual care did not improve sleep quality at 6 months (PSQI global mean 6.60 vs 6.08; P = .34).
02Poor sleep quality was reported by 85% of patients at month 1 and 55% at month 6.
03Higher AF symptom severity and higher anxiety or depression scores were associated with poorer sleep quality at 6 months.

What it does not show
The sleep analysis was explorative; the trial was powered for physical capacity and quality of life, not sleep quality. The PSQI has not been validated in an atrial fibrillation population. Only 173 of 210 randomized patients answered the sleep questionnaire at month 6. The intervention combined physical exercise and psychoeducational consultations, so the separate contribution of either component cannot be separated. No specific sleep intervention was delivered; sleep could only be discussed if the patient wanted. Participants were Danish-speaking adults treated in 2 university hospitals in Denmark.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not conclude that physical exercise or psychoeducational consultations improve sleep quality. The trial found no significant difference between groups, and the two components were given together, so their separate effects cannot be separated.
