Obstructive sleep apnoea (OSA) affects 11 per cent of pre-menopausal women though it often remains undetected. Women may present differently than men, and the classic findings of snoring, witnessed apnoeas and sleepiness may not be observed. Factors which predispose to OSA include polycystic ovarian syndrome, obesity, retromicrognathia, and hypothyroidism. OSA may contribute to neurocognitive d...

STUDY OBJECTIVES Obstructive sleep apnea (OSA) and metabolic syndrome represent significant risk factors for the development of cardiovascular disease. The purpose of this study was to see how frequently metabolic syndrome occurred in patients with OSA and whether the presence of metabolic syndrome was correlated with age, sex, or severity of OSA. METHODS We examined the records of 250 consec...

BACKGROUND Impaired renal function has recently been reported in obstructive sleep apnoea (OSA). The underlying mechanisms, however, are not entirely understood. This study investigated the influence of mild-to-moderate OSA and its treatment on renal haemodynamics as assessed by the renal resistance index (RRI). METHODS RRI has been measured by colour duplex ultrasound in 64 patients with new...

Obstructive sleep apnea (OSA) is a sleep breathing disorder affecting millions of people worldwide. It is medically significant because it has been shown to be a risk factor for the development of various cardiac pathologies, including atrial fibrillation (AF). Several studies have shown a correlation between OSA and AF and disparities of OSA occurrence in different ethnic and racial groups. We...

BACKGROUND Altered cardiovascular variability is a prognostic indicator for cardiovascular events. Patients with obstructive sleep apnea (OSA) are at an increased risk for cardiovascular disease. We tested the hypothesis that OSA is accompanied by alterations in cardiovascular variability, even in the absence of overt cardiovascular disease. METHODS AND RESULTS Spectral analysis of variabilit...

OBJECTIVE Overlap of obstructive sleep apnea (OSA) complicates diagnosis of depressive disorder and renders antidepressant treatment challenging. Previous studies have reported that the incidence of OSA is higher in patients with depression than in the general population. The purpose of this article was to investigate clinical risk factors to predict OSA in depression disorders. METHODS A tot...

BACKGROUND The mechanisms of atrial fibrillation (AF) induced by obstructive sleep apnea (OSA) are not completely understood. This study investigated the roles of the intrinsic and extrinsic cardiac autonomic nervous system in OSA-induced AF and provided noninvasive autonomic nervous modulation for the suppression of OSA-induced AF by using low-level transcutaneous electrical stimulation (LL-TS...

INTRODUCTION Obstructive sleep apnea (OSA) and non-alcoholic fatty liver disease (NAFLD) are both strongly associated with obesity. Whether OSA is an independent risk factor for liver injury is uncertain. OBJECTIVE To assess the hypothesis that OSA is associated with liver injury independent of obesity. MATERIALS AND METHODS We reviewed the histories of 73 consecutive patients referred to a...

1075 Ethnic Difference in OSA Risk Factors—Lee et al OBSTRUCTIVE SLEEP APNEA (OSA) IS A COMMON DISORDER IN WHICH RECURRENT SLEEP RELATED UPPER AIRWAY OBSTRUCTION CAUSES SLEEP fragmentation and intermittent hypoxemia. Ethnicity has been suggested as an important risk factor for OSA. However, defining the role of ethnicity is complex, as it incorporates genetic, environmental, and cultural factor...

BACKGROUND AND OBJECTIVE Recently, there are few studies reporting on depressive status and obstructive sleep apnoea (OSA) in China. A large-sample survey was to be performed to explore the prevalence of depressive status and related factors in Chinese patients with OSA. METHODS From among a randomly-selected group of OSA patients, 1,327 met inclusion criteria. After screening with the Sympto...
