This pilot study is looking into whether obstructive sleep apnea (OSA) is linked to atrial fibrosis (scarring in the heart's upper chambers). Researchers will use a special MRI scan called Delayed Enhancement Magnetic Resonance Imaging (DE-MRI) to measure the amount of atrial fibrosis in people with OSA who have not been diagnosed with atrial fibrillation (a type of irregular heartbeat). You may be able to join if you are 18-75 years old and have mild, moderate, or severe OSA. The study aims to enroll 60 participants. The current status of the study is unclear, so it's not known if they are actively recruiting.

Study design

This is a cross-sectional pilot study involving 60 participants with obstructive sleep apnea and 5 control participants. It is not specified if the study is randomized or blinded.

What's involved

You will undergo a DE-MRI scan. Your demographic information, medical history, and previous polysomnography (sleep study) results will be collected.

Compensation

Not stated in the trial record.

Follow-up

The primary endpoint, percentage of atrial fibrosis, is measured at the baseline visit. No further follow-up is specified.
