15 Preeclampsia, CPAP & Sleep Disordered Breathing—Blyton et al INTRODUCTION Preeclampsia is an important and common complication of pregnancy, characterized by the onset of hypertension after 20 weeks gestation with accompanying proteinuria, affecting approximately 5% of pregnancies. It is a major cause of maternal mortality and a risk factor for fetal growth restriction.1 Women with preeclamp...

Introduction : The prevalence of sleep-disordered breathing (SDB) and obstructive sleep apnea (OSA) in pregnant women has been estimated to range from 12% to 26.7% (1,2,3). Previous studies have evaluated SDB and/or OSA during pregnancy, but no study has specifically examined the first postpartum day. The first-day postpartum is associated with significant changes to maternal physiology and sle...

OBJECTIVES This prospective study investigated the prevalence of sleep-disordered breathing (SDB) and its predictors in patients with stable chronic heart failure (HF). BACKGROUND SDB is increasingly recognized as being important in patients with HF. METHODS The multicenter SchlaHF (Sleep-Disordered Breathing in Heart Failure) registry provides demographic and clinical data on chronic, stab...

STUDY OBJECTIVES To determine the prevalence of occult sleep disordered breathing (SDB) and describe the relationship between classic SDB symptoms (e.g., loud snoring) and occult SDB in older veterans with insomnia. METHODS We analyzed baseline survey and in-home sleep study data for 435 veterans (mean age = 72.0 years [SD 8.0]) who had no known history of SDB, met International Classificatio...

The relationship between sleep-disordered breathing (SDB) and nasal obstruction is unclear. In order to better understand, we performed an extensive computer-assisted review and analysis of the medical literature on this topic. Data were grouped into reports of normal control subjects, patients with isolated nasal obstruction, and those with SDB. We conclude that SDB can both result from and be...

Previous small-scale studies of the effect of sleep-disordered breathing (SDB) on prognosis in congestive heart failure (CHF) are either lacking or conflicting. The aim of this study was to assess the impact of the presence and type of SDB on mortality in a patient group with severe CHF referred to a specialised heart failure centre. Out of 78 patients ((mean +/- SD) 53 +/- 9 yrs, left ventricu...

To the Editor: Sleep disordered breathing (SDB) is underdiagnosed in children and difficult to differentiate from attention deficit hyperactivity disorder (ADHD). Both may present with similar symptoms of inattention, hyperactivity, irritability, and daytime sleepiness. Sleep disordered breathing includes primary snoring or obstructive sleep apnea, which are surprisingly common among children w...

Recent decades have seen the publication of numerous studies on the association between excessive sleep disordered breathing (SDB), particularly sleep apnoea, and an increase in cardiovascular morbidity and mortality. These studies have used a wide range of methodologies and criteria for patient inclusion. The results have been diverse, depending on the type of cardiovascular event or risk fact...

www.thoracic.org C LI P A N D C O P Y What is Sleep Disordered Breathing (SDB)? SDB is a general term used to describe various different abnormalities in breathing pattern which occur during sleep, including obstructive and central sleep apnea. Obstructive sleep apnea (OSA) is a common disorder which affects roughly 10% of the US population and approximately 1/3 of people with congestive heart ...

I nterest in abnormal breathing after stroke has a long history dating back at least to the observations of John Cheyne in 1818. In recent years this interest has been reawakened by a number of publications on the relations between sleep disordered breathing (SDB) and stroke. These studies have been of two main types—those investigating the possible increased risk of stroke in individuals with ...
