Obstructive sleep apnea and the risk of sudden cardiac death: A longitudinal study of 10,701 adults
Cause of Death
Death, Sudden, Cardiac
Sleep Apnea, Obstructive
In a population of 10,701 adults referred for polysomnography, OSA predicted incident SCD, and the magnitude of risk was predicted by multiple parameters characterizing OSA severity. Nocturnal hypoxemia, an important pathophysiological feature of OSA, strongly predicted SCD independently of well-established risk factors. These findings implicate OSA, a prevalent condition, as a novel risk factor for SCD.
