Editorial: The Complex and Instructive Relationship between OSA and Nocturnal Cardiovascular Death

Obstructive sleep apnea (OSA) is the most commonly encountered form of sleep disordered breathing (SDB) with clearly established cardiovascular (CV) morbidity and mortality.(1) The prevalence of this condition is estimated to be as high as 25% (one in five) in North America with similar rates in Asia and Europe, when defined as ≥5 apnea-hypopnea events (AHI) per hour on polysomnography (1-3). The prevalence of OSA is increasing worldwide, more so in developed nations and parallel to burgeoning obesity epidemics.
