Vitamin D and Cardiovascular Disease

Area of Science:

• Cardiovascular Medicine
• Endocrinology
• Nutritional Science

Background:

• Vitamin D is primarily recognized for its role in skeletal health.
• Emerging evidence highlights significant non-skeletal functions of vitamin D.
• Vitamin D deficiency is increasingly associated with adverse health outcomes beyond bone health.

Purpose of the Study:

• To review the non-skeletal actions of vitamin D.
• To examine the association between vitamin D deficiency and cardiovascular disease.
• To discuss the implications for clinical and population-level management.

Main Methods:

• Review of epidemiologic studies linking vitamin D deficiency to cardiovascular disease and hypertension.
• Analysis of animal model data demonstrating the impact of disrupted vitamin D signaling on cardiovascular parameters.
• Consideration of ongoing prospective randomized trials of vitamin D supplementation.

Main Results:

• Epidemiologic data consistently associate vitamin D deficiency with increased risk of cardiovascular disease and hypertension.
• Animal models show that impaired vitamin D signaling exacerbates hypertension, cardiac hypertrophy, and atherosclerosis.
• Prospective trials are underway to evaluate vitamin D supplementation in at-risk populations.

Conclusions:

• Vitamin D plays a crucial role in cardiovascular health, extending beyond its known skeletal functions.
• Vitamin D deficiency represents a modifiable risk factor for cardiovascular disease.
• Results from ongoing trials will inform clinical guidelines for vitamin D screening and supplementation strategies.
