“Cleveland Clinic’s Sleep Disorders Center has developed a focus in the area of sleep-disordered breathing (SDB) and atrial fibrillation (AF), identifying a strong magnitude of association in large population-based studies published in 2006 and 2009. Our investigations have also explored the intersection of both conditions with obesity. Yet an enduring knowledge gap surrounds interrelationships among SDB, obesity and AF following cardiac surgery.”

As stated in the article, SDB, which encompasses both obstructive and central sleep apnea, is characterized by repetitive upper airway collapse or cessation of breathing that is either complete (resulting in apneas) or partial (resulting in hypopneas). These sleep-related respiratory events are accompanied by intermittent bouts of hypoxemia, hypercapnia, autonomic dysregulation and intrathoracic pressure swings, leading to long-term adverse cardiovascular sequelae.
