NEW YORK (Reuters Health) - The blood pressure, nerve, and hormonal changes wrought by obstructive sleep apnea (OSA) may increase the risk of heart attack during the night, new research suggests.
OSA is a common problem in which tissues in the back of the throat temporarily collapse during sleep causing numerous, brief episodes of interrupted breathing. The condition, which can cause extreme daytime sleepiness, can be effectively treated with a special breathing device that alleviates the blockage by pushing air into throat.
