Snoring could be sign of future heart disease
There’s another reason to view snoring as a nighttime annoyance. New research indicates that snoring could be tied to increased risk for thickening and abnormalities in the carotid artery, which can be a precursor for many cardiovascular conditions.
The carotid artery is one of the large blood vessels that supply the brain with oxygen, and thickening of the lining of this artery could lead to serious health conditions. Researchers from Henry Ford Hospital in Detroit studied more than 900 patients, and those who snored were found to have a significantly higher intima-media thickness, which is one of the first warning signs of cardiovascular disease. It indicates the thickness of the two innermost layers of the arterial wall in the carotid artery.
Obstructive sleep apnea (OSA) -- a sleep disorder that occurs due to the collapse of the airway in the throat during sleep and causes loud snoring and periodic pauses in breathing -- has long been linked to cardiovascular disease. But this study suggests that the risk for cardiovascular disease may actually begin with snoring, long before it becomes OSA.
The results of this study found that snoring put people at higher risk for cardiovascular problems than smokers, overweight people and those with high cholesterol.
