It has been shown in several but not all studies that job strain, a combination of high psychological demands and low decision latitude, increases the risk of a first coronary heart disease (CHD) event. However, the association of job strain with the risk of recurrent CHD events after a first myocardial infarction (MI) has been documented in only 2 prospective studies whose findings were inconsistent. Two major limitations of these previous studies were that they did not assess the duration of psychosocial work exposure and were conducted with a limited number of participants. Our study was undertaken to determine whether job strain increases the risk of recurrent CHD events when the duration of psychosocial work exposure is taken into account in a large cohort who returned to work after a first recent MI.
