Vitamin D and Microvascular Function in Postmenopausal Women

Cardiovascular Diseases Clinical Trial

Official title:
Vitamin D Effects on Microvascular Function and Cardiovascular Risk Factors on Postmenopausal Women

Clinical Trial Summary

Many observational studies have demonstrated links between serum levels of 25-hydroxyvitamin D [25(OH)D] and cardiovascular risk (CVR) factors. Microvascular dysfunction relates not only to CVR but also to metabolic disease. Since cardiovascular disease (CVD) is the leading cause of death in postmenopausal women, it would be relevant to confirm this relationship. Maybe further studies would show that the correction of hypovitaminosis D could minimize the CVR. Our objective with this clinical trail is to analyze if vitamin D status is related to microvascular function and conventional cardiovascular risk (CVR) factors in postmenopausal women. For that we enrolled, in a pilot cross-sectional study, 39 non-smokers, low CVR postmenopausal women, with less than 10 years of hypoestrogenism and associations of 25(OH)D to adiposity, blood pressure, fasting aldosterone, insulin, glucose and lipid profile, HOMA-IR, parathormone and microvascular function, assessed by laser-Doppler flowmetry at cutaneous site, were investigated.
