Obstructive sleep apnea is associated with increased cardiovascular morbidity and mortality. We investigated myocardial perfusion using real-time quantitative myocardial contrast echocardiography with concurrent assessment of macrovascular and microvascular endothelial dysfunction in normotensive subjects with moderate-to-severe obstructive sleep apnea, who were compared with hypertensive and h...
Heart failure is an increasingly common public health problem that is strongly linked to both central and obstructive sleep apnea, collectively referred to as sleep-disordered breathing. Much attention has been given to the deleterious effects of sleep-disordered breathing on the failing heart and potential mechanisms by which treatment of sleep-disordered breathing may result in improved cardi...
Obstructive sleep apnea and dyslipidemia are common medical disorders that independently increase vascular morbidity and mortality. Current animal and human data show that, indeed, obstructive sleep apnea may mediate pathological alterations in cholesterol and triglyceride metabolism. The mechanisms involved are increased lipolysis, decreased lipoprotein clearance, and enhanced lipid output fro...
STUDY OBJECTIVES The objectives of this study were (1) to assess the prevalence of patent foramen ovale (PFO) by means of contrast transesophageal echocardiography (TEE) in patients with obstructive sleep apnea, and (2) to determine the potential contribution of right to left interatrial shunting to systemic oxygen desaturation following the performance of Valsalva maneuver. DESIGN Performanc...
Adenotonsillectomy is the most common surgery performed for sleep disordered breathing with good outcomes. Children with obesity, craniofacial disorders, and neurologic impairment are at risk for persistent sleep apnea after adenotonsillectomy. Techniques exist to address obstructive lesions of the palate, tongue base, or craniofacial skeleton in children with persistent sleep apnea. Children w...
Introduction: Children with cleft lip and/or palate are at increased risk of obstructive sleep apnea. The prevalence of obstructive sleep apnea in this population is unknown. The purpose of this study was to assess the frequency of obstructive symptoms and obstructive sleep apnea diagnosis in the cleft population. We hypothesized that obstructive symptoms present more frequently in children wit...
Background and purpose: Obstructive sleep apnea (OSA) is the most common type of sleep disorder which increases the risk of cardiovascular disease (CVD) and death. Despite the importance of OSA and its cardiovascular complications, most of the people with this disorder remain undiagnosed and untreated. The aim of this study was to evaluate the prevalence of at risk groups for OSA in cardiovascu...
Reduced upper airway muscle activity during sleep is a key contributor to obstructive sleep apnea pathogenesis. Hypoglossal nerve stimulation activates upper airway dilator muscles, including the genioglossus, and has the potential to reduce obstructive sleep apnea severity. The objective of this study was to examine the safety, feasibility and efficacy of a novel hypoglossal nerve stimulation ...
Abstract Background: There are many risk factors that predispose nurses to sleep disorders. In one hand, sleep disorder affects health and safety of nurses and patients and on the other hand, risk factors of this occupations raise the prevalance of sleep disorders and their complications. Materials and Methods: this study was done cross-sectionally on 190 nurses of Imam Khomeini hospital in ...
399 B oth sleep apnea and congestive heart failure are common disorders. However, systolic heart failure appears to be the most common cause of central and perhaps obstructive sleep apnea. Obstructive sleep apnea is also common in isolated diastolic heart failure and may contribute to the progression of left ventricular remodeling and perhaps play a causative role. 1,3-6 However, prevalence and...
