Scientists from Peking University in China found that snoring may increase the risk of stroke. results published In The Lancet.
82,339 people of Asian origin aged 30-79 were included in the study. Data on subjects were obtained from the Chinese biobank (biological sample repository) Kadoorie. Researchers performed Mendelian randomization (MR) analysis to evaluate the causal effect of snoring on the risk of total, hemorrhagic, and ischemic stroke. The MRI method is used to measure the cause-effect relationship between a modifiable risk factor and a phenotypic trait (most often a disease) of interest to the researcher.
The scientists also recorded the volunteers’ height and weight. During a basic health survey, study participants self-reported whether they snored. Then began the voluntary observation phase, which lasted more than 10 years.
During the follow-up period, 19,623 participants had a stroke. It was recorded that 11,483 of the cases were ischemic stroke and 5,710 were hemorrhagic. The results of the Mendelian randomization analysis confirmed a positive association between snoring and increased risk of all types of stroke.
Snoring can be an indirect cause of strokes in various ways. For example, it can cause oxygen starvation as a result of short-term apnea (cessation of breathing). This can lead to endothelial dysfunction, a pathological condition in which cells in the layer lining the inner surface of blood and lymph vessels become damaged due to oxidative stress.
Likewise, snoring can cause high levels of vibrations to affect the carotid artery and artery wall cells, which can cause the artery to rupture.
Preventing snoring may be more effective than weight control in preventing stroke, the scientists added.
