Working more than 55 hours a week increases the risk of arrhythmia

A large study has shown that people who work long hours have a higher risk of arrhythmias, which in turn leads to a stroke, heart failure, and memory loss.

According to the Telegraph, researchers at the University of London found that compared to those who worked 35 to 40 hours a week, those who worked more than 55 hours a week were more likely to have "atrial fibrillation". up to 45%. Atrial fibrillation is a form of arrhythmia that causes dizziness, shortness of breath, palpitations.

This finding is based on research conducted in 85 thousand people including men and women. They have been monitored for 10 years, their working hours and cardiovascular health are recorded through each stage.

For every 1000 people in the study, there were an additional 5.2 cases of atrial fibrillation that occurred among those who worked too often during the 10-year follow-up period.

Dr Mika Kivimaki of the University of London's Epidemiology Department, head of the study, said: " These findings suggest that excessive working time is associated with an increased risk of atrial fibrillation, The most common form of cardiac arrhythmia may be one of the mechanisms that explain the study of long-term people who have a higher risk of stroke. Atrium contributes to the development of stroke, but also causes other health disadvantages such as heart failure and stroke-induced memory impairment . "

Research shows that 9 out of 10 cases of atrial fibrillation occur in people with and without a history of heart disease, from which it can be seen that the increased risk is affected by the hours worked rather than by the money. history of illness in the past.

The study's authors said that young and healthy people do not need to worry much about this study, but those affected by other factors are at higher risk.

Professor Mika Kivimaki added: "The rate of atrial fibrillation for people at high risk of cardiovascular disease due to other factors such as old age, male sex, diabetes, high blood pressure, high cholesterol, excess Being overweight, smoking and being physically active, or having a history of heart disease is 40% higher than normal people, for healthy young people who have few "disabilities", even if they work in Long time is also less likely to suffer from atrial fibrillation ".

Heart charity organizations say more research is needed to understand the relationship between long-term work and abnormal heart rhythms.

Professor Sir Nilesh Samani, medical director of British Heart, once said: The idea that working for a long time can cause atrial fibrillation is very interesting.

"It is worth noting that this study clearly shows that the relationship between atrial fibrillation and working for hours does not involve other influencing factors that we already know. However, the nature of the study Research shows that these findings cannot confirm the cause of this relationship - either because of long-term work, may be the type of people of those people, or because some other factors have not been "We need to do more research to understand and prove what is behind this relationship. Only then can we consider the recommendations."

This finding was published in European Heart.
