A new study showed that job may increase the risk of developing some heart diseases such as coronary heart disease. This study was published in the Journal of the American Medical Association.
As Dr. Chantal Brisson from Universite Laval in Quebec noted that (This research is the first time that the result of stressful job has been considered in a large number of men and women of different ages who have returned to work after a first heart attack). Many early studies for heart diseases and attack have focused on the result of medical factors or individual characteristics including lifestyle. However, the effect of work environment has rarely been researched.
This study involved 972 participants (from 35 to 59 years of age). Those participants had experienced a first MI and were tracked for ten years approximately. Job Strain was evaluated through interviews performed at baseline, a few weeks after returning to work and at the second and the sixth years.
Work strain was based on two parameters: psychological stress and decision latitude. High work strain was cleared as high psychological stress and low decision latitude. The major focus was on the event of CHD in participants with and without chronic work strain, defined as high strain on the first two interviews
The results showed that a total of 206 patients experienced the combined outcome of fatal Coronary Heart Disease, nonfatal heart attack, or unstable angina. The study suggest to reduce the job stress to reduce the risk of developing heart diseases, Specially for those returned to work after a first heart attack.
