Sleep apnea may scar your heart without you knowing

NCT ID NCT04814420

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This pilot study at Tulane University is testing whether obstructive sleep apnea (OSA) can cause scarring (fibrosis) in the heart's upper chambers, even in people without atrial fibrillation. Researchers will use a special MRI with contrast dye to measure scarring in 60 adults with mild, moderate, or severe OSA. The goal is to see if OSA is an independent risk factor for heart scarring, which could lead to future treatments to prevent heart rhythm problems.

What this could mean

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

What this could lead to

If successful, this could show that sleep apnea directly causes heart scarring, pointing to the need for early treatment to prevent heart rhythm problems.

What could go wrong

This is a small, early pilot study (60 people) that only measures heart scarring on MRI. It cannot prove that sleep apnea causes scarring, and the results may not apply to everyone.
