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.
