T he potential role of sleep apnea in the pathogenesis and complications of cardiovascular disorders is a notion that recently has gained support.1,2 More specifically, several studies have been performed in order to analyze the association of hypertension in patients with sleep apnea and the potential importance of obstructive sleep apnea as a secondary and possible treatable cause of hyperten...

[Purpose] The aim of this study was to ascertain the prevalence of chronic widespread musculoskeletal pain in patients with obstructive sleep apnea syndrome and to assess the relationship between sleep disorder and pain, quality of life, and disability. [Subjects and Methods] Seventy-four patients were included in the study and classified as having mild, moderate, or severe obstructive sleep ap...

BACKGROUND Previous studies have documented a high prevalence of atrial fibrillation (AF) in individuals with obstructive sleep apnea (OSA). Central sleep apnea (CSA) has been associated with AF in patients with heart failure. However, data from prospective cohorts are sparse and few studies have distinguished the associations of obstructive sleep apnea from CSA with AF in population studies. ...

Although obstructive sleep apnea and cardiovascular disease have common risk factors, epidemiologic studies show that sleep apnea increases risks for cardiovascular disease independently of individuals' demographic characteristics (i.e., age, sex, and race) or risk markers (i.e., smoking, alcohol, obesity, diabetes, dyslipidemia, atrial fibrillation, and hypertension). Individuals with severe s...

Coexisting central and obstructive sleep apnea is a challenging clinical situation. We report a case exhibiting an overnight shift from obstructive to central events. The central sleep apnea component was related to sleep instability, hyperventilation and low nocturnal PaCO2. Both types of respiratory events were successfully treated with adaptive servoventilation.

Epidemiologic studies show that sleep apnea increases risks for cardiovascular disease independently of individuals’ demographic characteristics or risk markers i.e., smoking, alcohol, obesity, diabetes, dyslipidemia, atrial fibrillation, and hypertension. Individuals with severe sleep apnea are at increased risk for pulmonary arterial hypertension. The underlying mechanisms explaining associat...

Objective: The aim of this article is to provide a detailed description for obstructive sleep apnea regarding its signs and symptoms, the way it is diagnosed, the risk factors, management, the role of dentists and oral appliances in treatment and consequences of untreated condition. Material and Method: Electronic searching was done in PubMed, Medline, EMBASE and CENTRAL databases. Inclusion cr...

Obstructive sleep apnea is the result of repeated episodes of upper airway obstruction during sleep. Recent evidence indicates that alterations in upper airway anatomy and disturbances in neuromuscular control both play a role in the pathogenesis of obstructive sleep apnea. We hypothesized that subjects without sleep apnea are more capable of mounting vigorous neuromuscular responses to upper a...

Symptoms and signs in 12 patients with severe obstructive sleep apnea (OSA) syndrome have been presented. The most common symptoms were snoring , increased motor activity during sleep and excessive daytime somnolence. The factors predisposing to OSA syndrome were obesity and anatomic abnormalities of the upper airway structure. In some cases the signs of OSA syndrome included hypertension, righ...
