In the study of "Vitamin K supplementation and progression of coronary artery calcium in older men and women" by Shea MK, O'Donnell CJ, Hoffmann U, Dallal GE, Dawson-Hughes B, Ordovas JM, Price PA, Williamson MK, Booth SL., posted in US National Library of Medicine National Institutes of Health, found that phylloquinone supplementation slows the progression of Coronary artery calcification (CAC) in healthy older adults with preexisting CAC, independent of its effect on total matrix Gla protein (MGP) concentrations. Because our data are hypothesis-generating, further studies are warranted to clarify this mechanism.
