Obstructive sleep apnea is a very common disease and is associated with an increased risk of cardiovascular disease, cardiac arrhythmia, and stroke. Arterial stiffness is an emerging risk factor and may be involved in the cardiovascular complications of obstructive sleep apnea. The purpose of this review was to demonstrate the correlation between arterial stiffness and obstructive sleep apnea. ...

OBJECTIVE Obstructive sleep apnea is characterized by increased upper airway collapsibility during sleep. The present study investigated the use of the negative expiratory pressure test as a method to rule out obstructive sleep apnea. METHODS Flow limitation was evaluated in 155 subjects. All subjects underwent a diurnal negative expiratory pressure test and a nocturnal sleep study. The sever...

About one half of patients who have essential hypertension have obstructive sleep apnea, and about one half of patients who have obstructive sleep apnea have essential hypertension. A growing body of evidence suggests that obstructive sleep apnea is a major contributing factor in the development of essential hypertension. Despite many patients with obstructive sleep apnea having clear symptoms ...

Obstructive sleep apnea is characterized by total or partial interruptions of airflow during sleep, despite ongoing efforts to breathe. These pauses result from repeated upper airway obstructions that generate a systemic inflammatory condition with consequences for the endothelial function that increase the risk of cardiometabolic events. The prevalence of obstructive sleep apnea during pregnan...

Pediatric obstructive sleep apnea syndrome is a common disorder with important health consequences such as cognitive and behavioral problems, delay in somatic growth and cardiovascular complications. Polysomnography is used to diagnose and evaluate the severity of obstructive sleep apnea. The aim of this review is to discuss the definition, clinical findings, diagnosis and treatment of obstruct...

background and objective: obstructive sleep apnea (osa) is the most common respiratory disorder during sleep and a risk factor for myocardial ischemia. in this study, we evaluated the proportion of subjects at high risk for osa and prevalence of its predictors among patients admitted for acute myocardial infarction (mi). materials and methods : a total of 210 patients with mi admitted at the ca...

background and objective: obstructive sleep apnea (osa) is frequent and in some degree it affects about 24% of male and 9% of female in middle age adults. this study aimed to assess the association between risk of osa and cad. materials and methods : this case-control study was performed among 184 patients with a history of coro- nary angiography in two catheter labs at hospitals in qom, iran. ...

Introduction: This study aimed to investigate sleep architecture in patients with primary snoring and obstructive sleep apnea. Methods: In this study, we analyzed polysomnographic data of 391 clients who referred to Sleep Disorders Research Center (SDRS). These people were classified into three groups based on their Apnea-Hypopnea Index (AHI) and snoring; control, Primary Snoring (PS), and Obs...

OBJECTIVES The purpose of this study was to investigate the effect of a mandibular advancement device on different grades of obstructive sleep apnea using a relatively simple test for the apnea-hypopnea index to determine if a mandibular device will be effective. MATERIAL AND METHODS A total of 68 patients with obstructive sleep apnea syndrome (OSAS) including, 31 with mild, 23 with moderate ...

SETTINGS Preoperative assessment clinic. PATIENTS 305 surgical ASA physical status I, II, III, and IV patients. INTERVENTIONS Patients were screened with the Berlin questionnaire for obstructive sleep apnea. For patients de...
