Snoring not associated with increased mortality, cardiovascular disease, or stroke

As I have mentioned before, snoring has been implicated in cartoid artery blockages in animals, but not in humans. Obstructive sleep apnea (OSA), however, has been associated with cardiovascular disease and strokes. Here is a study from the Sleep Journal about snoring in humans. Researchers studied 380 subjects by having them undergo a home sleep study to assess snoring and OSA. The subjects were then followed for 17 years and their mortality information, cardiovascular disease incidence, and stroke incidence were recorded.

The results showed no association between snoring and mortality, cardiovascular disease, or strokes, when controlling for OSA and other factors. The results help us appreciate the importance of sleep studies, as they allow us sleep physicians to distinguish snoring from OSA.
