PY - 2015 T2 - Fishman's Pulmonary Diseases and Disorders, 5e AB - As outlined in Chapter 12, sleep occurs in distinct states classified broadly as non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep. These occur in a temporally organized fashion across the sleep period, with NREM dominating during the early hours of sleep and REM during the final hours of sleep. Myocardial infarction and ischemic stroke occur at a higher frequency during early morning hours,1–3 when REM sleep predominates. This temporal distribution of events may be explained at least in part by specific alterations in autonomic regulation during sleep. This chapter presents additional information on alterations in cardiopulmonary function during sleep.
