Summary

1\. Abstract

Introduction Coronary artery calcification (CAC) and especially progression in CAC is a strong predictor of acute myocardial infarction and cardiovascular mortality. A substudy in the recent Danish study, AVADEC, suggested a protective role of supplementation with vitamin K2 and D in the development of CAC. This finding should be interpreted with caution, but the perspective is very interesting. In this study, we will examine the effect of the supplementation on progression of CAC in men and women with severe CAC. We hypothesize that the supplementation will slow down the calcification process.

Method and analysis In this multicenter and double-blinded placebo-controlled study, 400 men and women with CAC score ≥ 400 are randomized (1:1) to treatment with vitamin K2 (720 µg/day) and vitamin D (25 µg/day) or placebo treatment (no active treatment) for two years. Exclusion criteria are treatment with vitamin K antagonist or coagulation disorders. To evaluate CAC score, a non-contrast CT-scan is performed at baseline and repeated after 12 and 24 months of follow-up. Primary outcome is difference in CAC score from baseline to follow-up at two years. Intention-to-treat principle is used for all analyses.

Ethics and dissemination There are no reported adverse effects associated with the use of vitamin K2. Prior to inclusion, the protocol will be approved by the Regional Scientific Ethical Committee for Southern Denmark and the Data Protection Agency. It will be conducted in accordance with the Declaration of Helsinki. Positive as well as negative findings will be reported.
