Objectives: The aim was to examine and compare the impact of HeartScore and coronary artery calcification (CAC) score on subsequent changes in the use of medication. Methods: A total of 1156 healthy men and women, aged 50 or 60, had a baseline medical examination and a coronary artery CT-scan as a part of a screening programme. Using the European HeartScore, the total 10-year cardiovascular mortality risk was estimated (≥5% risk was considered as high). Risk factors and CAC scores were reported to both the patients and their general practitioner. Six months after the screening, follow-up questionnaires addressing current medication were mailed to the participants. Results: A completed questionnaire was returned by 1075 (93%) subjects. At follow up, the overall use of prophylactic medication was significantly increased. Of those with CAC (n = 462) or high HeartScore (n = 233), 21 and 19%, respectively, received lipid-lowering treatment, while 25 and 32%, respectively, received antihypertensive treatment. In multivariate logistic regression analyses, the presence of CAC was associated with an increased use of lipid-lowering treatment (OR 2.2; 95% CI 1.2-4.0), while the presence of a high HeartScore was associated with an increased use of lipid-lowering (OR 2.9; 95% CI 1.6-5.5) and antihypertensive medication (OR 3.4; 95% CI 1.9-6.0). Conclusion: Knowledge of present cardiovascular risk factors like high HeartScore and/or CAC leads to beneficial changes in medication. However, at follow up only a minority of high-risk subjects did received prophylactic treatment. CAC score was not superior to HeartScore regarding these motivational outcomes.
