Full-night polysomnography is necessary for the diagnosis of obstructive sleep apnoea (OSA). However, analysis of the sleep stages and apnoeas is time-consuming. Computer systems for automated analysis have, thus, been developed to alleviate this task. We investigated 27 consecutive patients referred to our sleep laboratory with suspected OSA. The analysis of sleep stages and apnoeas was perfor...

Obstructive sleep apnoea (OSA) affects 9-24% of the adult population. OSA is associated with atrial disease, including atrial enlargement, fibrosis and arrhythmias. Despite the link between OSA and cardiac disease, the molecular changes in the heart which occur with OSA remain elusive. To study OSA-induced cardiac changes, we utilized a recently developed rat model which closely recapitulates t...

BACKGROUND Obstructive sleep apnoea (OSA) is a condition causing repetitive episodes of upper airway obstruction during sleep, leading to hypoxia and/or sleep disturbance. OSA affects 1-5% of children and has important implications for learning, behaviour and cardiovascular health. OBJECTIVE The aim of this article is to provide a suggested approach to case finding and treatment of OSA for ge...

In the study by KENDZERSKA et al. [1] published in this issue of the European Respiratory Journal, it is reported that obstructive sleep apnoea (OSA) and severity measures, such as the apnoea/hypopnea index, are not related to the risk of hospitalisation for depression. The sample of the study was large with >10000 subjects, and the follow-up period was long, ∼10 years. The investigators focuse...

Obstructive sleep apnoea (OSA) is a sleep disorder characterized by recurrent episodes of oxygen desaturation during sleep, representing an independent risk factor for cardiovascular disease, such as myocardial infarction, stroke, congestive heart failure and resistant hypertension. Several neurohormonal mechanisms have been suggested to account for blood pressure increases, such as sympathetic...

BACKGROUND Obstructive sleep apnoea (OSA) elicits a number of cardiovascular perturbations that could lead acutely or chronically to increased ventricular ectopy in patients with heart failure (HF). We tested the hypothesis that treatment of OSA with continuous positive airway pressure (CPAP) in patients with HF would reduce the frequency of ventricular premature beats (VPBs) during sleep in as...

BACKGROUND Obstructive sleep apnoea (OSA) has recently been identified as a possible aetiology for chronic cough. The aim of this study was to compare the incidence of chronic cough between patients with and without OSA and the impact of continuous positive airway pressure (CPAP) treatment in resolving chronic cough. METHODS Patients referred to the sleep laboratory from January 2012 to June ...

Background: Obstructive sleep apnoea (OSA) elicits a number of cardiovascular perturbations that could lead acutely or chronically to increased ventricular ectopy in patients with heart failure (HF). We tested the hypothesis that treatment of OSA with continuous positive airway pressure (CPAP) in patients with HF would reduce the frequency of ventricular premature beats (VPBs) during sleep in a...

The aim of the present study was to evaluate ischaemic reactive hyperaemia (IRH) in obstructive sleep apnoea (OSA) and its relationship with oxidative stress. We studied 69 consecutive patients referred to our Sleep Unit (Reina Sofia University Hospital, Cordoba, Spain). Patients with chronic diseases or those taking medication were excluded. IRH was assessed before and after polysomnography. M...

Abstract Background The importance of assessing patients for paediatric obstructive sleep apnoea (OSA) cannot be more highly stressed and orthodontists may play an essential role in risk screening. Paediatric Sleep Questionnaire (PSQ) is a validated tool to identify whether child at OSA. Objectives likelihood OSA school-aged children residing Far North Queensland (FNQ) will assessed using the P...
