Sleep-disordered breathing (SDB) describes a group of disorders characterised by abnormalities in the frequency and/or depth of breathing while asleep. The most common type is the obstructive sleep apnoea/hypopnoea syndrome (OSAHS); it affects 2-4% of the adult population and is an independent risk factor for hypertension. Another type is central sleep apnoea (CSA), which includes Cheyne-Stokes...

The main characteristics of sleep-disordered breathing (SDB) are airflow limitation, chronic intermittent hypoxia, or apnea; which may lead to tissue hypoperfusion and recurrent arousal from sleep. These episodes of hypoxia or apnea can lead to tissue inflammation, and are causal factors of disturbed sleep in both men and women. Several lines of evidence suggest that sleep patterns differ along...

The objective of this article is to review the available data on the relationship between sleep-disordered breathing (SDB) and pulmonary arterial hypertension (PAH), with a focus on the prevalence of SDB in patients with idiopathic PAH (IPAH); the prevalence of PAH in patients with SDB; and the effects of SDB treatment on PAH. The evidence to date suggests that PAH may occur in the setting of S...

Rationale: Sleep-disordered breathing (SDB) has been associated with total and cardiovascular mortality, but an associationwith cancer mortality has not been studied. Results from in vitro and animal studies suggest that intermittent hypoxia promotes cancer tumor growth. Objectives: Thegoalof thepresent studywas toexaminewhetherSDB is associated with cancer mortality in a community-based sample...

Sleep problems are common in people with multiple sclerosis (MS). Reported prevalence rates of sleep-disordered breathing (SDB) vary between 0 and 87%. Differences in recruitment procedures and study designs likely contribute to the wide variance in reported prevalence rates of SBD in MS. This can make attempts to compare SDB rates in people with MS to the general population challenging. Little...

OBJECTIVES Research on the effects of sleep-disordered breathing (SDB) on sleep structure has traditionally been based on composite sleep-stage summaries. The primary objective of this investigation was to demonstrate the utility of log-linear and multistate analysis of the sleep hypnogram in evaluating differences in nocturnal sleep structure in subjects with and without SDB. METHODS A commu...

BACKGROUND Unlike the well-established association between sleep disordered breathing (SDB) and chronic heart failure, the relationship between SDB and severe aortic stenosis (AS) is not well investigated. Given the increasing prevalence of AS, and the improving prognosis of high risk AS patients attributable to transcatheter aortic valve implantation (TAVI), the prevalence and impact of SDB ne...

STUDY OBJECTIVES Patients with Prader-Willi syndrome (PWS) suffer from excessive sleepiness and sleep disordered breathing (SDB). We reviewed the polysomnograms (PSGs) and multiple sleep latency tests (MSLTs) in a cohort of PWS patients to determine the relationship of BMI(Z) scores, daytime sleepiness, growth hormone (GH) treatments, and SDB. METHODS Attended overnight PSGs were performed fo...

Orofacial myofunctional disorders (OMD) and sleep-disordered breathing (SDB) may present as comorbidities. characteristics might serve a clinical marker of SDB, allowing early identification management OMD improving treatment outcomes for sleep disorders. The study aims to characterize in children with SDB symptoms investigate possible relationships between the presence various components SDB. ...

Sleep-disordered breathing (SDB) is the major determinants of hypertension. Recent studies indicated sleep duration, in addition to shift work, were also associated with hypertension. But very little attention has been paid to these two factors when looking at the effects of SDB on blood pressure. We conducted the present study to evaluate the relationship between SDB and hypertension adjusting...
