Vitamin D and cardiovascular disease.

Area of Science:

• Endocrinology
• Cardiovascular Medicine
• Nutritional Science

Background:

• Vitamin D traditionally regulates calcium and phosphorus metabolism for skeletal health.
• Active vitamin D metabolites influence nonskeletal tissues via local synthesis.
• Vitamin D receptors are present in key cardiovascular cells like cardiomyocytes and immune cells.

Purpose of the Study:

• To review clinical associations between vitamin D status and cardiovascular disease.
• To explore experimental evidence for vitamin D's role in cardiovascular pathways.
• To summarize findings on vitamin D's impact on cardiovascular function and disease.

Main Methods:

• Review of clinical studies correlating vitamin D levels with cardiovascular disease.
• Analysis of experimental research on vitamin D's mechanisms in cardiovascular systems.
• Examination of vitamin D receptor roles in cardiovascular cell types.

Main Results:

• Vitamin D deficiency is independently associated with cardiovascular diseases, including vascular calcification.
• Experimental studies show vitamin D influences inflammation, thrombosis, and the renin-angiotensin system.
• Vitamin D receptors regulate genes critical to cardiovascular processes like cell proliferation and apoptosis.

Conclusions:

• Vitamin D plays a significant role in cardiovascular health beyond skeletal regulation.
• Further research is needed to establish the efficacy of vitamin D supplementation for cardiovascular disease management.
