|HealthExtra: On-the-job straining is a heart risk|
A number of studies have shown that job stress increases the risk of a first coronary heart disease (CHD) event. Now experts say people who experience chronic job strain after a first heart attack have twice the risk of another CHD event, such as a heart attack or unstable angina, than those without on-the-job stress. Researchers studied more than 970 men and women ages 35 to 59 who returned to work after a first heart attack. After nearly six years, chronic job strain—defined as the degree of high psychological demands and low decision control—was associated with a twofold risk increase in recurring CHD, even after adjusting for more than two dozen risk factors.
