Work stress linked to heart risk

People who go back to a stressful job after a heart attack are more prone to a second attack than those whose work is not stressful - a study says.

Canadian researchers followed some 1,000 patients returning to work.

In six years, over 200 suffered heart problems again. Those with job strain were twice as likely to fall ill. The Journal of the American Medical Association study defined job strain as having a high pressure workload but few decision-making powers.

Studies have also shown a link between job strain and a first heart attack, but researchers at Laval University in Quebec said little was known about the association with subsequent heart problems.

They said their findings on Canadian patients held up even after other risk factors had been accounted for, including lifestyle, socio-economic group and clinical prognosis.
