[A comparison of results of simple evaluation of the risk of ischemic heart disease with calculations based on a multiplicative model].
A simple model for detection of subjects at risk of ischaemic heart disease, based on the addition of scores for different risk factors (Anggaard EE, Land JM, Lenihan J et al. Br Med J 1986; 293: 177-80), is at present widely applied in Denmark. The model could be tested in a prospective study, or a historical follow-up study, but we do not have the possibilities to do so. Instead we have compared the risk score of the model with the estimated five-year coronary mortality risk (ECR) in 742 men aged 40-44 years, calculated on the basis of data from the Seven Countries Study. There is a reasonable consistency in this comparison, in spite of the different principles of calculation, the consideration of different risk factors and/or weighting of risk factors. For example, the model has a sensitivity of 71%, a specificity of 89% and a positive predictive value of 68% in detecting 40-44 year old men in the upper quartile of ECR. The "false positives" are often men, who for other reasons may require preventive medical attention (obese heavy smokers), and the "false negatives" are often men with isolated hypertension.
