11-hour work days ‘can increase heart attack risk by 67pc’

London, Apr 5 (ANI): Those who spend more than 11 hours at work increase their chance of having a heart attack by two thirds, according to a new study.

Researchers from University College London say the risk is so great that GPs should ask patients what hours they work along with how much they drink or smoke.

The research team looked at more than 7,000 civil servants working in Whitehall over a period of 11 years and established how many hours they worked on average a day.

They also collected information including the condition of their heart from medical records and health checks.

Over the period, a total of 192 had suffered a heart attack. But the study found that those who worked more than 11 hours a day were 67 per cent more likely to have one than those who had a ‘nine to five’ job.

“We have shown that working long days is associated with a remarkable increase in risk of heart disease,” the Daily Mail quoted Professor Mika Kivimaki, who led the study, as saying.

“It could be a wake-up call for people who over-work themselves, especially if they already have other risk factors,” Professor Kivimaki added.

The study has been published in the journal Annals of Internal Medicine. (ANI)
