Background Obstructive sleep apnoea (OSA) is a heterogeneous disorder, and improved understanding of physiologic phenotypes their clinical implications needed. We aimed to determine whether routine polysomnographic data can be used identify OSA (clusters) assess the associations between cardiovascular outcomes. Methods Cross-sectional longitudinal analyses multisite, observational US Veteran (n=1247) cohort were performed. Principal components-based clustering was features in OSA’s four...

Periodic limb movements during sleep (PLMS) cause repetitive sympathetic activation and may be associated with increased cardiovascular risk. We hypothesized that PLMS frequency (periodic movement index [PLMI]) arousal [PLMAI]) are predictive of incident disease, including coronary heart peripheral arterial cerebrovascular in an elderly male cohort.

Background: Restless legs syndrome (RLS) is a common sensorimotor disorder whose incidence not known.The aim of the study was to determine and correlates RLS in population-based sample.Methods: We obtained data from Tucson Cohort Sleep Heart Health Study, prospective multicenter study.This cohort included 535 participants aged ≥ 40 years, who answered questions regarding on 2002 2006 sleep surveys.For this study, defi ned as presence all 4 International Study Group criteria, with symptoms...

In rodent models, obesity and hyperglycemia alter cerebral glucose metabolism transport into the brain, resulting in disordered function as well inappropriate responses to homeostatic hedonic inputs. Whether similar findings are seen human brain remains unclear. this study, 25 participants (9 healthy participants; 10 obese nondiabetic 6 poorly controlled, insulin- metformin-treated type 2 diabetes mellitus (T2DM) participants) underwent 1H magnetic resonance spectroscopy scanning occipital...

To determine whether sleep-disordered breathing (SDB) is associated with cardiac arrhythmia in a clinic-based population multiple cardiovascular comorbidities and severe SDB.This was cross-sectional analysis of 697 veterans who underwent polysomnography for suspected SDB. SDB categorized according to the apnea-hypopnea index (AHI): none (AHI < 5), mild (5 ≥ AHI 15), moderate-severe 15). Nocturnal arrhythmias consisted of: (1) complex ventricular ectopy, (CVE: non-sustained tachycardia,...

We sought to determine whether is among various A total of 1740 men women underwent measurement pressure polysomnography quantification PLMS. Hypertension was defined as systolic (SBP) ≥140, diastolic BP ≥90, or taking antihypertensive medication. For those antihypertensives, an estimated pretreatment SBP...

<strong>Background:</strong> In the past few decades, much has been learned about pathophysiology of restless legs syndrome (RLS). Investigators have studied neuropathology, imaging, electrophysiology, and genetics RLS, identifying brain regions biological systems affected in RLS. This manuscript will review RLS literature, examining state through consideration neuroanatomy, then biological, organ, genetic systems. <strong>Methods:</strong> Pubmed (1966 to April 2016) was searched for term...

Its conspicuous occurrence during sleep suggests that WUS may be associated with obstructive apnea (OSA). We investigated the potential association among WUS, OSA, and measures sympathetic hyperactivity. &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt; This is cross-sectional analysis data from Sleep Apnea in Transient Ischemic Attack Stroke (SLEEP TIGHT) study. patients were...

Background Mechanisms underlying blood pressure (BP) changes in obstructive sleep apnoea (OSA) are incompletely understood. We assessed the associations between BP and selected polysomnography (PSG) traits: depth, airflow limitation measurements OSA-specific hypoxic burden. Methods This cross-sectional analysis included 2055 participants from Multi-Ethnic Study of Atherosclerosis who underwent PSG 2010–2013. Sleep depth was using ‘OR product’, a continuous measure arousability. Airflow by...

We examined the associations snoring several measurements SA with subclinical carotid atherosclerosis in a large multiethnic population sample. Methods— This analysis included 1615 participants (mean age, 68 years) from examination 5 (2010–2013) MESA study (Multi-Ethnic Study Atherosclerosis).
