Can a sleep machine stop heart rhythm problems after ablation?

NCT ID NCT07444372

First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study looks at whether using a CPAP machine for sleep apnea after a heart procedure (catheter ablation) can help prevent atrial fibrillation from coming back. About 658 adults with both conditions will be randomly assigned to use CPAP for a year or receive usual care. The goal is to see if CPAP reduces the chance of irregular heart rhythms.

What this could mean

Our plain-language read of the trial. This is informational only โ€” not medical advice or a prediction.

Active substance
Continuous Positive Airway Pressure (CPAP) device
What this could lead to
If it works, this could provide a clear way to lower the chance of atrial fibrillation returning after ablation in people with sleep apnea.
What could go wrong
Previous small trials have not shown a clear benefit, possibly because patients didn't use the CPAP enough. This trial is still recruiting, and results may not apply to everyone.
