Abstract
BACKGROUND. Where health professionals and patients hold similar views of a problem, health outcomes may be better. AIM. The aims of this paper were to document how attenders at primary care cardiovascular screening clinics perceived their risks of coronary heart disease prior to screening; the degree of similarity between perceived level of risk and an epidemiologically derived risk score; and the relative importance assigned to individual risk factors by subjects compared with those assigned by the risk score. METHOD: These issues were investigated in 3725 middle aged men and women who accepted an invitation to attend health screening as part of the British family heart study. RESULTS. Overall, there was a tendency for subjects to be optimistic (37%) rather than pessimistic (21%) when judging their risk of coronary heart disease. Nevertheless, there were strong significant associations between perceived risk and the levels of individual risk factors, particularly personal and family medical history and body mass index. There was also a strong association with the overall risk score though a large minority (31%) held views of their risk of coronary heart disease that were quite different from those based upon the epidemiologically derived index of risk. Respondents accorded greater importance to smoking and parental death from coronary heart disease and less importance to cholesterol level and blood pressure than did the risk score. CONCLUSION. Possible explanations for the observed disagreement are over-optimism or the relative importance given to individual risk factors. The relationships between patients' perceptions of risk and the epidemiological indices likely to be espoused by health professionals are important in understanding the difficulties in communication that might arise in offering lifestyle advice after screening for cardiovascular risk.
