“These medical tests are needed to improve the diagnosis of sleep apnea and sleep disorders in general,” Michael Twery, PhD, the former director of the National Center on Sleep Disorders Research at the NHLBI, said in a news statement from the Institute. [5]“Potential candidate markers hav...
Recently, two well-designed studies by research-ners from the University of Wisconsin1 and thenSleep Heart Health Study Group2 documented thatnuntreated obstructive sleep apnea (OSA) increasesnthe risk for hypertension in American adults. In bothnstudies, the risk for hypertension increased in an...
Just how sleep apnea worsens blood pressure is not well understood, but up to one in five people may suffer from it. When the National Institutes of Health put out a call for proposals on sleep apnea research several years ago, Kanagy realized UNM’s experie...
Employing a measure rarely used in sleep apnea studies, researchers at the UCLA School of Nursing have uncovered evidence of what may be damaging the brain in people with the sleep disorder—weaker brain blood flow. In the study, published Aug. 28 in the peer-reviewed journalPLOS ONE, researc...
Sleep apnea itself isn't thought to be fatal. But research has found that people who have the condition are twice as likely to die suddenly within a given time period than those who don't--especially if it's not treated. That's because of its links to serious conditions like high blood...
Studies shed light on how sleep fragmentation patterns differ by age and gender, as well as the heart rate impacts of sleep apnea.
Research on the current prevalence of OSA indicated that one-third of sleep studies showed some degree of OSA (apnea-hypopnea index ≥5 events per hour of sleep) (2). Among adults 30 to 70 years of age, approximately 13% of men and 6% of women have moderate to severe forms of OSA (...
Research recommends sleep apnea screening before surgery. Credit: J.P. Rathmell Scheduled for surgery? New research suggests that you may want to get screened and treated for obstructive sleep apnea (OSA) before going under the knife. According to a first-of-its-kind study in the October issue...
With increasing age, the prevalence of sleep apnea increases and reaches a plateau around 65 years old9. Ageing is considered one of the risk factors for OSA10, and is also included in both STOP-BANG11 and OSA5012 questionnaires. To explore the aging effects on OSA, most studies focused ...
Obstructive sleep apnea(OSA) is defined as complete or partialairway obstructioncausing intermittent cessation of breathing during sleep. That will lead to intermittenthypoxemia,hypercapnia, microarousals, and disconnected sleep.63,64Studies report that more than 60% of stroke patients have OSA.65,66OS...
