Note: This paper adds another hypothesis as to WHY increased COPD increases CVD
Seem feasible - I was unable to find out how often anticogulants are used with worsening COPD
- COPD and Osteoporosis are related – vitamin D is one possible connection – 2013
- Vascular calcification greatly reduced by 1000 ug of Vitamin K2 MK-7 – Dec 2013
- Low Vitamin K2 is as risky as smoking for heart disease - Oct 2016
- Decreased need for warfarin after Vitamin D levels optimized – RCT May 2016
less warfarin needed and thus less loss of Vitamin K if high level of Vitamin D

Cardiovascular diseases are prevalent in patients with chronic obstructive pulmonary disease (COPD). Their coexistence implies that many COPD patients require anticoagulation therapy. Although more and more replaced by direct oral anticoagulants, vitamin K antagonists (VKAs) are still widely used. VKAs induce profound deficiency of vitamin K, a key activator in the coagulation pathway. It is recognized however that vitamin K is also an essential cofactor in the activation of other extrahepatic proteins, such as matrix Gla protein (MGP), a potent inhibitor of arterial calcification. No or insufficient MGP activation by the use of VKAs is associated with a rapid progression of vascular calcification, which may enhance the risk for overt cardiovascular disease. Vitamin K consumption, on the other hand, seems to have a protective effect on the mineralization of arteries.
Furthermore, vascular calcification mutually relates to elastin degradation, which is accelerated in patients with COPD associating with impaired survival. In this commentary, we hypothesize that vitamin K is a critical determinant to the rate of elastin degradation. We speculate on the potential link between poor vitamin K status and crucial mechanisms of COPD pathogenesis and raise concerns about the use of VKAs in patients with this disease. Future intervention studies are needed to explore if vitamin K supplementation is able to reduce elastin degradation and vascular calcification in COPD patients.
