About
To learn if there is a connection between low vitamin D level and hardening of the arteries.
Full description
Osteoporosis and vascular disease are two of the most common disorders affecting postmenopausal women. A potential association, beyond aging, has long been speculated. Our previous study revealed evidence of loss of vascular compliance in postmenopausal women with lower bone density, suggesting women with lower bone density had "stiffer" blood vessels. This proposal further investigates that association and a potential role of vitamin D deficiency as a possible common link between both bone loss and "hardening of the arteries".
