Background The role of psychosocial factors in the aetiology of coronary heart disease continues to be debated. Despite public perception of a major role for their effect, scientific opinion on their relevance remains divided. This paper reviews the literature on the influence of social support and life stress on coronary heart disease incidence and mortality. Methods Observational studies published in English, based on over 100 human subjects from the general population, investigating life stress or social support were considered. Fourteen studies derived from MEDLINE searches on MeSH headings: coronary disease; stress, psychological; social support; social isolation; life change events. An equivalent search of BIDS and studies referenced by papers identified using these sources was carried out.
