According to a new study, researchers found that patients with obstructive sleep apnea have enlarged and thickened hearts that pump less effectively. However, these heart abnormalities improve with use of a device that helps patients breathe better during sleep.

Bharati Shivalkar, M.D., who published her findings in the Journal of the American College of Cardiology, says, "Not only are the shape and size of the heart affected, the right side of the heart was dilated and the heart muscle on the left side was thicker in patients with obstructive sleep apnea, but the pump function was also reduced. The changes were directly related to the severity of the problem. Treating the problem brought significant improvements in the affected parameters, as well as in symptoms, in a relatively short period of time of six months
