Специалисты из Новосибирска под руководством профессора Валерия Гафарова пришли к выводу, что плохой сон может значительно увеличить риск инфаркта и инсульта. Исследователи уверены: есть все основания включить пункт «плохой сон» в список факторов риска сердечно-сосудис
Ученые в течение 14 лет наблюдали за участниками исследования MONICA, целью которого было изучение причин сердечно-сосудис
У 63% участников, у которых на протяжении наблюдения развился инфаркт миокарда, имелись расстройства сна. Риск сердечного приступа у них был повышен в 2-2,6 раза, а вероятность развития инсульта в 1,5-4 раза в сравнении с людьми, чей сон был нормальным. Максимально «рискованным» в плане сердечно-сосудис
Также было обнаружено, что люди, у которых произошли инфаркты и инсульты на фоне нарушений сна, зачастую были социально неблагополучными (вдовцы, разведенные, а также те, кто имел низкий уровень образования, занимался тяжелым или умеренно тяжелым физическим трудом).

Poor sleep may raise the risk of heart attack, stroke
A new study suggests it can significantly increase our risk of heart attack and stroke, prompting researchers to call for it to be considered as a risk factor for cardiovascular disease in prevention guidelines for the condition.
For this latest study, Prof. Valery Gafarov, of the Russian Academy of Medical Sciences in Novosibirsk, Russia, and colleagues wanted to determine whether poor sleep may be tied to risk of heart attack and stroke, which cause almost 80% of all deaths from cardiovascular disease.
«Sleep disorders are very closely related to the presence of cardiovascular diseases,» notes Prof. Gafarov. «However, until now there has not been a population-based cohort study examining the impact of sleep disorders on the development of a heart attack or stroke.»
The team recently presented their findings at EuroHeartCare 2015 — the annual conference of the European Society of Cardiology. The team’s study was a part of the World Health Organization’s (WHO) Multinational Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA) program and the «MONICA-psychoso
The study, which began in 1994, included a nationally representative cohort of 657 men aged 25-64 from Russia, all of whom had no history of diabetes, stroke or heart attack. At study baseline, researchers used the Jenkins Sleep Scale to identify sleep frequency and any sleep difficulties among participants. Men whose ratings fell into the categories of «poor,» «bad» or «very bad» were considered to have a sleeping disorder.
The team assessed incidence of heart attack and stroke among the participants over the next 14 years. Compared with men who did not have a sleeping disorder, those who did were found to be at 2-2.6 times greater risk of heart attack and 1.5-4 times higher risk of stroke.
Among men with sleeping disorders, the risk of stroke and heart attack was highest among those who were widowed or divorced, those who had professions that involved heavy to medium manual labor and those who had not completed high school. According to the National Sleep Foundation, adults aged 18-64 should get around 7-9 hours sleep each night, while those aged 65 and older should aim for 7-8 hours sleep each night.
Prof. Gafarov says individuals who are not getting enough sleep should talk to their doctor, pointing out that not only could poor sleep raise the risk of heart attack and stroke, but previous studies from the team have linked it to greater risk of hostility, depression and anxiety.
