Atrial Fibrosis in Obstructive Sleep Apnea Patients: A Pilot Study

This pilot study is exploring whether sleep apnea — a condition where breathing repeatedly stops during sleep — causes scarring in the heart's upper chambers (atria). Scarring can lead to an irregular heartbeat called atrial fibrillation. Researchers want to see if the severity of sleep apnea is linked to how much scarring develops. **You may be eligible if...** - You are between 18 and 75 years old - You have been diagnosed with sleep apnea (mild, moderate, or severe) confirmed by a sleep study - You may or may not have a history of atrial fibrillation (irregular heartbeat) **You may NOT be eligible if...** - You do not have a confirmed sleep apnea diagnosis - You fall outside the 18–75 age range Talk to your doctor to see if this trial is right for you.
