Atrial Fibrosis in Obstructive Sleep Apnea Patients: A Pilot Study
Trial Parameters
Brief Summary
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).
