Description: Children who snore and breathe irregularly while they sleep may be at risk for developing cardiovascular disease, according to researchers at the University of Louisville in Circulation, Journal of the American Heart Association. A team under the direction of David Gozal, director of the Kosair Children’s Hospital Research Insitute and chief of pediatric sleep medicine at UofL, found that obstructive sleep apnea could harm blood vessels, but that treating OSA in a timely fashion could help prevent future heart disease in some children.
