Neurology: poor sleep at night may increase the risk of stroke and heart disease

November 8, 2019 / bioun / - recently, a research report published in the international journal Neurology found that people with sleep difficulties (poor sleep) are more likely to suffer from stroke, heart disease or other cerebrovascular or cardiovascular diseases Photo source: Dr Liming Li, researcher of cc0 public domain, said that relevant research results show that we may be able to use behavioral therapy to intervene and treat patients with sleep difficulties, so as to reduce their risk of multiple diseases; in this study, the researchers included 487200 people with an average age of 51 years in the study, and the participants did not History of stroke or heart disease; participants were asked if they had three insomnia symptoms (at least three times a week): difficulty falling asleep or having difficulty falling asleep; waking up too early in the morning; inability to focus during the day due to poor sleep A total of 11% of the participants had difficulty falling asleep, 10% of the participants said they got up too early, 2% of the participants could not concentrate in the daytime due to poor sleep, and the researchers did not determine whether these people fully met the definition of insomnia The researchers then followed the participants for about 10 years, during which 130032 suffered from strokes, heart attacks and other similar diseases Participants with these three insomnia symptoms were 18% more likely to develop these diseases than those without any symptoms, and the researchers then adjusted for other factors that affect the risk of stroke or heart disease, including alcohol consumption, smoking and physical activity levels Participants with sleep disorders or difficulty sleeping were 9% more likely to have a stroke or heart attack than individuals without any sleep disorders, 17650 (32%) of the 55127 people with the disorder had a stroke or heart attack, and 112382 (26%) of the 432073 people without the disorder had a stroke or heart attack 。 Those who got up too early in the morning and couldn't fall asleep again had a 7% increased risk of disease compared to participants who didn't have the sleep problem, while those who couldn't concentrate during the day due to poor sleep had a 13% increased risk compared to those who didn't The association between insomnia symptoms and these diseases is more significant in young people and people who did not have high blood pressure at the beginning of the study, so they should pay more attention to the early detection of these people and the development of corresponding interventions later, said Li, the researcher This study does not clarify the causal relationship between insomnia symptoms and the risk of stroke and heart disease, but only one kind of correlation; the limitation of this study is that participants' self-report on their insomnia symptoms may not be accurate; in addition, the researchers did not ask participants to sleep well, which may be another insomnia Common symptoms Original source: Bang Zheng, canqing Yu, Jun LV, et al Insomnia symptoms and risk of cardiovascular diseases among 0.5 million results a 10 year cohort Neurology, 2019 doi: 10.1212/wnl.0000000000008581
