Do psychosocial factors cause coronary heart disease
or affect survival among patients with coronary heart disease? Here we use an explicit methodological quality filter to review systematically the prospective cohort studies testing specific psychosocial
hypotheses. This review of the epidemiological literature identifies
the psychosocial factors that have been most rigorously tested. Only
four psychosocial factors met the quality filter: type A/hostility,
depression and anxiety, work characteristics, and social supports. The
importance of other study designs

ecological1 or nested case-control2-4 studies
is acknowledged. The review should be seen as complementary to
existing reviews5-8 on single psychosocial factors and as a challenge to investigators in the field to ensure that the systematic review is made unbiased, kept up to date, and used to guide future hypothesis testing.
