Study finds that obstructive sleep apnea causes earlier death in stroke patients
May 19, 2008Stroke victims who have obstructive sleep apnea die sooner than stroke victims who do not have sleep apnea or who have central sleep apnea, according to Swedish researchers, who will present their findings at the American Thoracic Society's 2008 International Conference in Toronto on Monday, May 19.
The researchers followed 132 stroke patients over 10 years. Twenty-three of those patients had obstructive sleep apnea; 28 of those patients had central sleep apnea. Those with an obstructive apnea-hypopnea index of 15 or greater were 76 percent more likely to die earlier. Those with a lower apena-hypopnea index of 10 were also at greater risk of early death.
"The findings are particularly interesting because obstructive sleep apnea is a treatable condition," said Karl Franklin, M.D., who led the research team at University Hospital in Umea, Sweden.
The researchers' results were independent of age, gender, smoking, body-mass index, hypertension, diabetes, atrial fibrillation, cognitive ability and how dependent patients were on help in their daily lives.
According to Dr. Franklin, patients with central sleep apnea tended to have an increased risk of earlier death, but unlike those with obstructive sleep apnea, that risk was not independent of confounders.
Earlier research Dr. Franklin and his colleagues conducted using trans-cranial Doppler found that cerebral blood flow and arterial blood pressure increase during obstructive apneas and then rapidly decrease to low values when the apnea ends. This pattern, the researchers said, suggests cerebral ischemia occurs at the same time as oxygen saturation is low.
The findings of their latest study, Dr. Franklin noted, indicate the importance of a clinical trial for stroke patients with obstructive sleep apnea to see whether treating the sleep disorder will extend their lives.

Obstructive Sleep Apnea Current Events and Obstructive Sleep Apnea News RSSNew light on link between snoring and cognitive deficits in children
About two-thirds of children with sleep-disordered breathing (SDB)- snoring or obstructive sleep apnea (OSA)- have some degree of cognitive deficit, but the severity of the cognitive deficit has been notoriously difficult to correlate to the severity of the SDB.
Erectile dysfunction related to sleep apnea may persist, but is treatable
For sufferers of sleep apnea, erectile dysfunction (ED) is often part of the package. New research indicates that ED in cases of obstructive sleep apnea syndrome (OSAS) may be linked to the chronic intermittent hypoxia-oxygen deprivation- (CIH) that patients with OSAS experience during episodes of obstructed breathing.
Study shows heavy snoring is an independent risk factor for carotid atherosclerosis
A study in the Sept. 1 issue of the journal Sleep shows that objectively measured heavy snoring is an independent risk factor for early carotid atherosclerosis, which may progress to be associated with stroke.
Study shows that surgical weight loss does not eliminate obstructive sleep apnea
A study in the August 15 issue of the Journal of Clinical Sleep Medicine shows that surgical weight loss results in an improvement of obstructive sleep apnea (OSA), but most patients continue to have moderate to severe OSA one year after undergoing bariatric surgery.
Sleep apnea a stand-alone mortality risk
An independent link between sleep apnea and mortality has been discovered by a group of Australian researchers, suggesting the prevention and treatment of this condition should be a higher priority for government bodies working to improve community health.
Memory loss linked to common sleep disorder
For the first time, UCLA researchers have discovered that people with sleep apnea show tissue loss in brain regions that help store memory.
Primary snoring in children impacts cardiovascular functioning
Primary snoring in children may have an impact on cardiovascular functioning equivalent to that of moderate obstructive sleep apnea (OSA), according to a research abstract that will be presented Wednesday at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS).
Sleep problems linked to obesity, lower quality of life in school-aged children
A research abstract that will be presented on Tuesday at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS), finds an increased prevalence of sleep problems among school-aged children who are obese and an association between increased weight and lower quality of life.
Treatment at an AASM accredited sleep center improves long-term CPAP compliance
Obstructive sleep apnea (OSA) patients are more likely to comply with continuous positive airway pressure (CPAP) for longer periods of time if they receive their treatment from a sleep center accredited by the American Academy of Sleep Medicine (AASM).
Link between migranes and sleep disorders in children
Children with a migraine headache are more likely to have sleep disorders, such as obstructive sleep apnea (OSA) and lack of sleep, than children without a migraine.
