Study explains link to increased cardiovascular risks for people with obstructive sleep apnea

Posted by in categories: biotech/medical, health

Researchers have found that people with obstructive sleep apnea have an increased cardiovascular risk due to reduced blood oxygen levels, largely explained by interrupted breathing. Obstructive sleep apnea has long been associated with increased risk of cardiovascular issues, including heart attack, stroke, and death, but the findings from this study, published in the American Journal of Respiratory and Critical Care Medicine, show the mechanism mostly responsible for the link.

“These findings will help better characterize high-risk versions of obstructive ,” said Ali Azarbarzin, Ph.D., a study author and director of the Sleep Apnea Health Outcomes Research Group at Brigham and Women’s Hospital and Harvard Medical School, Boston. “We think that including a higher-risk version of obstructive sleep apnea in a would hopefully show that treating sleep apnea could help prevent future cardiovascular outcomes.”

Researchers reviewed data from more than 4,500 middle-aged and older adults who participated in the Osteoporotic Fractures in Men Study (MrOS) and the Multi-Ethnic Study of Atherosclerosis (MESA), and sought to identify features of obstructive sleep apnea that could explain why some people were more likely than others to develop cardiovascular disease or related death.
