Filter by:Obstructive sleep apnea (OSA) is an increasingly common chronic disorder in adults. Compared to the general population, OSA occurs more often in patients with coronary artery disease (CAD), with a reported prevalence of 38% to 65%. Emerging evidence indicates OSA initiates and exacerbates coronary atherosclerosis. Moreover, several observational studies indicate the presence of OSA was associated with higher rate of restenosis and repeat revascularization (mainly attributed non-culprit lesion revascularization) after percutaneous coronary intervention (PCI). OSA might initiate endothelial injury by repetitive bursts of sympathetic activity that occur with apneas and hypopneas. Moreover, untreated OSA reduces endothelial repair capacity. Whether OSA could exacerbate neointimal proliferation and plaque progression in the non-culprit lesion after drug-eluting stent (DES) implantation remains less studied. The investigators aimed to evaluate neointimal proliferation and strut coverage within stent segment as well as changes of plaque volume and morphology in the non-culprit lesion by optical coherence tomography (OCT) in patients with versus without OSA at 12-month follow-up.
This study aims to see if mobile video clips (smartphone recordings) can be used to screen children with Down syndrome to identify those at highest risk of obstructive sleep apnea (OSA), so they can be prioritized for an earlier sleep study. Parents will be asked to record short video clips of their child sleeping, and then rate whether they think their child has OSA. Later, children will undergo a sleep study to compare to the ratings.
The aim of this study is to evaluate the efficacy of a combination of Continuous Positive Airway Pressure (CPAP) and a Mandibular Advancement Device (MAD) on nocturnal Blood Pressure control in hypertensive patients in obstructive sleep apnea low CPAP compliers (less than 4 hours per night). Hypertensive patients demonstrating low CPAP adherence will be selected during a screening visit; they will be then randomized to one of the three following arms: Education to CPAP ("CPAP only"), Treatment by a MAD ("MAD only") or a combination of both CPAP and MAD ("CPAP+MAD"). Mean systolic, diastolic, diurnal and nocturnal blood pressure will be assessed during 24-h Ambulatory Blood Pressure monitoring, before and after a 3-month treatment intervention. Biological laboratory parameters, patients reported outcomes (daytime sleepiness and Quality of Life), will also be evaluated before and after 3 months of treatment.
This study examines the combined effects of an angiotensin receptor blocker (ARB), antioxidant supplementation, and continuous positive airway pressure (CPAP) therapy on the lowering of 24-hour blood pressure in persons with moderate to severe Obstructive Sleep Apnea (OSA). All participants will undergo CPAP therapy as prescribed by their doctor; however, half of the participants will receive the combined ARB and antioxidant treatment while the other half of the participants will receive a placebo.
Sleep disorders are important health issues that can reduced ones quality of life by affecting their performance and productivity in a negative way. People who work in shifts or doing 24 hours call usually have irregular sleep patterns and often complaint of fatigue and daytime sleepiness. This will jeopardized our attention, concentration ability and memory which may lead to serious job accidents. This study is to screen for obstructive sleep apnea among doctors working in a tertiary hospital and to determine the predictors of OSAS and tiredness among doctors who frequently work night shifts or 24 hour call. What would this involve? Participant will be required fill up demographic data and answer the STOP-Bang and Epworth sleepiness scale questionnaires. After that participant will need to wear a wrist watch pulse oximeter just before going to sleep at night until the next morning (minimum of 6 hours of sleep required). The wrist watch will then be returned to researcher the following day for data analysis purpose. The benefits We hope to screen and identify those who are at risk of having obstructive sleep apnea and start early treatment among doctor who often have irregular sleep patterns and insufficient sleep due to the nature and timing of their work.
The primary study objective is to investigate sensitivity and specificity of a wrist sensor pulse oximeter (the Oxitone Medical Oxitone 1000M device) to screen for obstructive sleep apnoea. This study will involve thirty participants attending a sleep centre suspected of suffering from obstructive sleep apnoea (case finding screening). The secondary objective is to assess patient convenience with the screening procedure.
The purpose of this study is to learn about the effect of sleep apnea and low oxygen on muscle strength and lung function in people with chronic spinal cord injury.
This study will evaluate the effect of treatment of obstructive sleep apnea on insulin sensitivity in pregnant women. Women in their third trimester of pregnancy will be randomized to receive treatment or no treatment for one month.
This investigation is designed to evaluate the comfort, ease of use and performance of a trial nasal mask for the treatment of Obstructive Sleep Apnea (OSA) in the home environment.
This study purpose is to evaluate the association between Retinal Vein Occlusion and Obstructive Sleep Apnea.
