Aims: To compare the predictions of the Systematic Coronary Risk Evaluation (SCORE) high- and low-risk functions applied to a recent population study with observed cardiovascular disease (CVD) mortality estimated from annual official mortality statistics in Norway.
Methods: Data were obtained from large epidemiological surveys conducted in five Norwegian counties in 2000-2003.
Results: A total of 32 251 men and women were investigated (aged 30-31, 40-41, 45-46, and 59-61). For men aged >or=59, more than 75% qualified for preventive treatment by having a 10-year risk >or=5%. Few women and practically no men younger than 46 years can be considered at high risk according to the SCORE risk prediction models. For men, the high-risk function overestimated and the low-risk model underestimated the CVD mortality as compared to the 10-year risks calculated from official mortality statistics (1999-2003). For women, however, both functions underestimated mortality in young individuals, whereas in the elderly an overestimation was observed.
Conclusions: The risk predictions depended strongly on age and gender. The SCORE high-risk function overestimates the risk of fatal CVD for men in Norway, and before implementation in clinical practice, proper adjustments to national levels are required.
