Obstructive sleep apnea during rapid eye movement sleep in patients after percutaneous coronary intervention: a multicenter study.

Purpose: Obstructive sleep apnea (OSA) during the rapid eye movement (REM) stage of the sleep cycle is associated with intense hypoxemia and cardiovascular instability. We characterized OSA during REM sleep in patients after percutaneous coronary intervention.

Methods: In this multicenter study, 204 patients who had undergone percutaneous coronary intervention in the prior 6 to 36 months were recruited for in-laboratory polysomnography.

Obstructive Sleep Apnea and Cardiovascular Events After Percutaneous Coronary Intervention.

Background: There is a paucity of data from large cohort studies examining the prognostic significance of obstructive sleep apnea (OSA) in patients with coronary artery disease. We hypothesized that OSA predicts subsequent major adverse cardiac and cerebrovascular events (MACCEs) in patients undergoing percutaneous coronary intervention.

Methods And Results: The Sleep and Stent Study was a prospective, multicenter registry of patients successfully treated with percutaneous coronary intervention in 5 countries.

Overview of sleep disorders.

Sleep disorders are common and can affect anyone, from every social class and every ethnic background. It is estimated that more than 70 million Americans are afflicted by chronic sleep disorders. Currently about 88 sleep disorders are described by the International Classification of Sleep Disorders as established by The American Academy of Sleep Medicine.
