Study: 3.4 pct of heart attacks attributed to job strain

September 14, 2012

If your job is highly demanding, and you have little freedom to make decisions, you are 23 percent more likely to have a heart attack. That's compared with less stressed out colleagues.

But lighting up a cigarette or remaining chained to your desk rather than getting out to do some exercise is far more damaging for your heart health. That's the finding of a study online in the Lancet Medical Journal.

Researchers studied nearly 200,000 people and found 3.4 percent of heart attacks can be attributed to job strain.

They say that's a significant proportion, but far less than the 36 percent attributable to smoking and 12 percent due to lack of exercise.
