Professor Gafarov said: "Mortality from cardiovascular diseases accounts for nearly 50% of the total mortality among the population. Nearly 80% of deaths from cardiovascular disease are due to myocardial infarction (heart attack) and stroke. It means that today we are talking about an epidemic of cardiovascular disease. It is therefore necessary to engage in intensive prevention of risk factors leading to the development of cardiovascular diseases."

He continued: "Sleep disorders are very closely related to the presence of cardiovascular diseases. 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."

Men with a sleeping disorder had a risk of myocardial infarction that was 2 to 2.6 times higher and a stroke risk that was 1.5 to 4 times higher than those without a sleeping disorder between 5 and 14 years of follow up.

Professor Gafarov said: "Sleeping disorders were associated with greatly increased incidences of both heart attack and stroke. We also found that the rates of heart attack and stroke in men with sleeping disorders were related to the social gradient, with the highest incidences in those who were widowed or divorced, had not finished secondary school, and were engaged in medium to heavy manual labour."

He added: "Sleep is not a trivial issue. In our study it was associated with double the risk of a heart attack and up to four times the risk of stroke. Poor sleep should be considered a modifiable risk factor for cardiovascular disease along with smoking, lack of exercise and poor diet. Guidelines should add sleep as a risk factor to recommendations for preventing cardiovascular disease."

Professor Gafarov continued: "For most people, good quality sleep is 7 to 8 hours of rest each night. People who are not sleeping well should speak to their doctor. Our previous research showed that sleeping disorders are very closely connected with depression, anxiety and hostility, so speaking with a psychologist may also help."
