Increasing evidence proved that obstructive sleep apnea (OSA) is associated with a variety of diseases, especially cardiovascular diseases. This study systematically reviewed the existing publications to assess the influence of OSA on cardiovascular survival among patients who underwent percutaneous coronary intervention. Eleven eligible publications, including 3,008 participants, were finally evaluated. Eight studies conducted adjustment of risk ratio for potential cardiovascular risk factors, 5 studies defined OSA groups as AHI (apnea hypopnea index) ≥15/hour, whereas the remaining eligible studies used AHI ≥5/hour, AHI ≥10/hour, or AHI ≥30/hour as the criteria...

The primary pathological event in the disorder obstructive sleep apnea (OSA) is the partial or complete closure of the pharyngeal airway during sleep in an individual with a widely patent airway during wakefulness. This yields an apnea or hypopnea with resulting hypoxia and hypercapnia, and most often requires an arousal to terminate the event. These events occur in a repetitive manner during sleep, yielding intermittent hypoxia and sleep fragmentation with their associated adverse effects on the health and quality of life of the afflicted individual...

Numerous studies report that difficulty breathing through the nose is associated with reduced sleep quality, increased daytime dysfunction, and increased risk of snoring and obstructive sleep apnea (OSA). Additionally, chronic nasal obstruction often complicates and limits successful medical device therapy for OSA, particularly with continuous positive airway pressure (CPAP). When medical evaluation and management of the nose is inadequate, surgical therapy to lower nasal resistance has been shown to substantially improve sleep and breathing outcome measures...

Continuous positive airway pressure (CPAP) is the primary treatment of obstructive sleep apnea/hypopnea syndrome (OSA). Most sleep physicians are in agreement that a certain number of OSA patients cannot or will not use CPAP. Although other conservative therapies, such as oral appliance, sleep hygiene, and sleep positioning, may help some of these patients, there are many who fail all conservative treatments. As sleep surgeons, we have the responsibility to screen patients for both symptoms and signs of OSA...

If untreated, obstructive sleep apnea (OSA) develops as a gradual progressive disease. In the early stage of the disease most patients with OSA are positional. The archetypical patient might progress from simple positional snoring via positional early-stage mild disease to less positional moderate and finally nonpositional severe OSA. At first, the apnea-hypopnea index (AHI) is high only in the supine position, and later is high in all sleeping positions. The phenomenon is reversible. After partial effective treatment, patients with severe OSA can reverse to less severe positional OSA or, in other words, the AHI drops more in the lateral position than in supine position...

INTRODUCTION: This study tested the hypotheses that late-midlife obstructive sleep apnea (OSA) and short and long sleep duration are associated with dementia for more than 15 years of follow-up. METHODS: A total of 1667 Atherosclerosis Risk in Communities Study participants underwent in-home polysomnography (1996-1998) and were followed for dementia. Dementia was defined by (1) hospitalization diagnosis codes (1996-2012) and (2) a comprehensive neurocognitive examination (2011-2013) with adjudication...

BACKGROUND: An analysis of cardiac injury markers in patients with obstructive sleep apnea (OSA) who sustain an episode of acute coronary syndrome (ACS) may contribute to a better understanding of the interactions and impact of OSA in ACS subjects. We compared peak cardiac troponin-I (cTn-I) levels in patients admitted for ACS with and without OSA. METHODS: Blood samples were collected every 6 hours from the time of admission until 2 consecutive assays showed a downward trend in the cTn-I assay...

OBJECTIVE: Sleep during pregnancy involves a physiological challenge to provide sufficient gas exchange to the fetus. Enhanced ventilatory responses to hypercapnia and hypoxia may protect from deficient gas exchange, but sleep-disordered breathing (SDB) may predispose to adverse events. The aim of this study was to analyze sleep and breathing in healthy pregnant women compared to non-pregnant controls, with a focus on CO2 changes and upper-airway flow limitation. METHODS: Healthy women in the third trimester and healthy non-pregnant women with normal body mass index (BMI) were recruited for polysomnography...

STUDY OBJECTIVES: Continuous positive airway pressure (CPAP) is effective but challenging for children with obstructive sleep apnea (OSA). High-flow air via open nasal cannula (HFNC) as treatment in children remains controversial. We report the efficacy of HFNC in children with OSA and CPAP intolerance, a titration protocol, and a discussion of potential mechanisms. METHODS: Patients aged 1 to 18 years with OSA (defined by obstructive apnea-hypopnea index [OAHI] greater than 1 event/h) and CPAP intolerance were enrolled...

The etiology and pathogenesis of sleep obstructive apnea hypopnea syndrome (OSAHS) is not yet definitive, evidence shows that the dysfunction of pharyngeal nerve and the atonia of the muscle innervated by these nerve could play an important role in the progress of OSAHS. Dopamine is a neurotransmitter in the central nervous system which significantly affects the sleep-awake regulation. So far mounting evidence shows that dopamine has a potential role in the modulation of hypoglossal nucleus. The progress of dopamine in obstructive sleep apnea hypopnea syndrome is reviewed in this article...
