AI-Summary

What this Trial Is About

The investigators hypothesize that Obstructive Sleep Apnea (OSA) is an independent risk factor for atrial fibrosis development. The investigators aim to prove the presence of atrial fibrosis on Delayed Enhancement Magnetic Resonance Imaging (DE-MRI) in OSA patients without atrial fibrillation (AF).
