Sleep apnea treatment may cut heart ablation need in AFib patients
NCT ID NCT04606693
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looks at whether screening for and treating sleep apnea can reduce the burden of atrial fibrillation (AFib) in patients who are candidates for heart ablation. Fifty adults with paroxysmal or persistent AFib that hasn't responded to medication will be screened for sleep apnea. Those diagnosed will receive standard treatment (like CPAP or lifestyle changes) and be monitored for three months. The goal is to see if their AFib improves enough to avoid the need for ablation.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- CPAP and lifestyle measures for sleep apnea
- What this could lead to
- If successful, this could show that treating sleep apnea helps control atrial fibrillation, potentially reducing the need for heart ablation in some patients.
- What could go wrong
- This is a small, non-randomized study with only 50 participants, so results may not apply broadly. It is also early-stage and observational, so it cannot prove cause and effect.
