We reviewed the epidemiologic research on the relationship between psychosocial factors at work and ischemic heart disease (IHD). A literature search identified 35 longitudinal English-language studies published in peer-reviewed journals. Nine out of 18 cohort studies and 14 out of 17 case control studies showed a significant association between psychosocial factors at work and IHD. In three of the studies, the results showed the expected association without it being significant, and in nine of the studies no association was found. Twenty-nine of the studies achieved a satisfactory quality score of at least 16 points out of a possible 25. Among these, 19 found a positive association between psychosocial factors at work and IHD. Nineteen of the studies had used the job strain model suggested by Karasek and Theorell as the model of exposure. Eleven of these found a clear association between job strain and IHD, three found a partial association, and five showed negative results. Three of the negative studies had used the ecological method as the measure of exposure. None of the five American studies found any association between job strain and IHD. The 11 positive studies were carried out in the UK, Sweden, the Czech Republic, and Denmark. An imbalance between efforts rendered and rewards, as well as long working hours, was also found to increase the risk of IHD in the six studies which had looked into these exposures. The results of this literature review ought to have consequences for the prevention of IHD and affect the advice offered to IHD patients.
