Cardiac deaths peak in sleep hours for patients with sleep apnea
...realized," Dr. Gami explains. "We clearly have two distinct populations, with opposite times of highest cardiac death risk." Dr. Somers cautioned that the study could not determine whether OSA raises the overall risk of sudden cardiac death, or whether it simply shifts the risk to the sleeping hours.
