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.
