And if you survive that and return to the same job, you're far more likely to suffer a second attack than someone who finds a less stressful position.
Researchers followed the progress of 1,000 people who suffered a heart attack. In six years, more than 200 of them suffered a second attack, and that was twice as likely to happen if they were in a stressful job.
The researchers, from Laval University in Quebec, define a stressful job as one with a heavy workload and with few, if any, powers of decision-making.
