Altered cardiac contractility in sleep apnea.
Adrenergic regulation in sleep apnea is a complex process because adrenergic physiology is difficult to summarize with one measure. Furthermore, the role of the adrenergic system in sleep apnea is often confounded with hypertension, making interpretation difficult in hypertensive apneics. Sixty-six people with and without apnea and/or hypertension (all were off antihypertensive medication) part...
متن کاملSleep Apnea & Cardiac Arrhythmias
INTRODUCTION Sleep apnea syndrome (SA) is a common breathing disorder that affects 5% of the North American adult population, with men being affected almost twice as much as women [1]. The condition has well defined associations with increased cardiovascular morbidity and mortality, arrhythmia, daytime hypersomnolence, motor vehicle accidents and neurocognitive dysfunction; but despite this it ...
متن کاملAltered cardiovascular variability in obstructive sleep apnea.
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...
متن کاملCardiac arrhythmias, snoring, and sleep apnea.
We investigated the frequency of cardiac arrhythmias in patients suspected of having sleep apnea, and related them to the severity of apnea, snoring, and nocturnal hypoxemia. We prospectively studied 458 patients who had nocturnal polysomnography which included objective measurement of snoring (quantified by the number of snores per hour of sleep [snoring index (SI)] and maximum nocturnal sound...
متن کاملAltered Regional Brain Cortical Thickness in Pediatric Obstructive Sleep Apnea
Rationale Obstructive sleep apnea (OSA) affects 2-5% of all children and is associated with cognitive and behavioral deficits, resulting in poor school performance. These psychological deficits may arise from brain injury, as seen in preliminary findings of lower gray matter volume among pediatric OSA patients. However, the psychological deficits in OSA are closely related to functions in the c...
