Shift work boosts heart attack risk
Monday July 30th 2012
Heart attack risk is heightened by unsocial working hours, research has shown.
A major review of health effects based on working patterns found that the risk of suffering a heart attack can jump by more than a fifth as a result of shift work.
It also found that the risk of suffering a stroke increases by 5% when working unsocial hours.
Shift workers are more likely to suffer a coronary event, which includes angina chest pains, with heart attacks up by 23% and any coronary event up by 24%.
In Canada, where a number of the researchers were based, 7% of heart attacks could be attributed to shift work.
The scientists, led by Dr Daniel Hackam, from Western University in Canada, wrote in the British Medical Journal: "Shift work is associated with vascular events, which may have implications for public policy and occupational medicine."
