Untreated sleep apnea shown to raise metabolic and cardiovascular stress — ScienceDaily

Sleep apnea, left untreated for even a few days, can increase blood sugar and fat levels, stress hormones and blood pressure, according to a new study of sleeping subjects. A report of the study’s findings, published in the August issue of The Journal of Clinical Endocrinology & Metabolism, adds further support for the consistent use of continuous positive airway pressure (CPAP), a machine that increases air pressure in the throat to keep the airway open during sleep.

Jun emphasized that the study was limited by studying people with severe OSA and obesity, thus limiting the ability to apply the findings to all OSA patients. The researchers also did not compare CPAP use to a sham CPAP control group to exclude a potential placebo effect

Sleep Apnea Linked to Cancer

Sleep Apnea Linked to Cancer.

Moderate-to-severe OSA was associated with a 2.5-fold higher likelihood of incident cancer (95% CI 1.2-5.0) after adjustment for obesity and a full range of other factors, Nathaniel Marshall, PhD, of the University of Sydney Nursing School in Australia, and colleagues found.

Cancer mortality was 3.4 times more common (95% CI 1.1-10.2) in those with sleep apnea than with no sleep apnea during 20 years of follow-up, they reported in the April 15 issue of theJournal of Clinical Sleep Medicine.

Sleep Apnea Plays Role in Car Crashes

An estimated 20% to 50% of commercial drivers have sleep apnea. That high proportion may be in part due to the sedentary nature of long-haul trucking that contributes to obesity as a risk factor for sleep apnea, according to a statement from the American Academy of Sleep Medicine in support of federal legislation.

Sleep Apnea Severity Tied to Cardiac Marker

  • Obstructive sleep apnea is associated with cardiovascular morbidity and mortality, particularly heart failure, a study found.
  • The severity of obstructive sleep apnea was significantly associated with higher levels of high-sensitivity troponin, suggesting that subclinical myocardial injury may play a role in the association with risk of heart failure.
