Prevalence, risk factors, and type of sleep apnea in patients with paroxysmal atrial fibrillation

ConclusionsIn our AF population, SA was highly prevalent and predominantly obstructive. The high prevalence of SA detected in this study may indicate that SA is under-recognized in patients with AF. None of the screening questionnaires predicted SA reliably.

Conclusions: Of two commonly used questionnaires to screen for SA, neither the SBQ nor the BQ questionnaire discriminated well between those with or without SA in patients with PAF. Until better screening tools are available PG or PSG needs to be used to detect SA in these patients.

Introduction: OSA has a polygraphic definition based on the HAI. It generates nocturnal desaturation responsible for cellular hypoxia with multi-visceral impact mainly cardiac such as arrhythmias.The purpose of our study was to investigate whether peripheral saturation can be a means of descrambling to diagnose OSAS in a population followed for AF.Methods: Analytical prospective study including 100 patients followed for AF. None of the recruited patients had been followed for OSA before. Each patient had a clinical examination and a polygraphy. Patients were divided into 2 groups: G1: with OSA and G2: without OSA.Results: ...

Obstructive sleep apnea (OSA), a condition in which the soft tissues of the throat relax and narrow the airways during sleep, may raise the risk of developing heart problems after surgery, according toresearch published this week inJAMA. In OSA, breathing stops and starts multiple times during sleep, resulting in snoring, gasping for air, poor sleep quality, morning headaches, daytime fatigue, irritability, and difficulty concentrating.The study, led by Matthew T. V. Chan, Ph.D., M.B.B.S., of the Chinese University of Hong Kong included 1,218 patients aged 45 years or older who had abdominal, vascular, or major orthopedic ...

(CNN) — Hey, sleepyheads. What you believe about sleep may be nothing but a pipe dream. Many of us have notions about sleep that have little basis in fact and may even be harmful to our health, according to researchers at NYU Langone Health’s School of Medicine, who conducted a study published Tuesday in the journal Sleep Health. “There’s such a link between good sleep and our waking success,” said lead study investigator Rebecca Robbins, a postdoctoral research fellow in the Department of Population Health at NYU Langone Health. “And yet we often find ourselves debunking myths, whether ...

Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this techniqu...

Authors: Wojda M, Jurkowski P, Lewandowska A, Mierzwińska-Nastalska E, Kostrzewa-Janicka J Abstract Obstructive sleep apnea (OSA) is a sleep disorder resulting from the repetitive narrowing and collapse of the upper respiratory tract. The results of previous epidemiological studies confirm a significant impact of OSA on the health situation around the world. Untreated OSA is associated with many adverse health effects, such as hypertension, coronary artery disease, stroke, atrial fibrillation, congestive heart failure, and daytime sleepiness. Excessive mortality of OSA patients, especially in men under 50 yea...

Study Objectives:To examine the cross-sectional association between obstructive sleep apnea (OSA) risk and atrial fibrillation (AF) in the REasons for Geographic And Racial Differences in Stroke (REGARDS), a cohort of black and white adults.Methods:Using REGARDS data from subjects recruited between 2003–2007, we assessed 20,351 participants for OSA status. High OSA risk was determined if the participant met at least two criteria from the Berlin Sleep Questionnaire (persistent snoring, frequent sleepiness, high blood pressure, or obesity). AF was defined as a self-reported history of a previous physician diagnosis or ...

In conclusion, the STOP-BANG questionnaire is sensitive; however, it has a low specificity with a high false positive rate. Given that a large number of atrial fibrillation patients need testing for OSA, we recommend the use of a level II sleep study regardless of the results of the screening questionnaire. This approach accurately identifies OSA and may limit the cost of unnecessary level-I sleep studies. PMID: 29682848 [PubMed - as supplied by publisher]

We examined whether patients at increased risk for OSA, assessed by the STOP-BANG (snoring, tired during the day, observed stop breathing during sleep, high blood pressure, body mass index more than 35 kg/m, age more than 50 years, neck circumference more than 40 cm, and male gender) questionnaire, had a higher incidence of new-onset postoperative atrial fibrillation after cardiac surgery. Because both postoperative atrial fibrillation and OSA increase resource utilization, we secondarily examined whether patients at increased OSA risk had longer duration of postoperative mechanical ventilation and intensive care unit (ICU...
