Vitamin D and Cardiovascular Diseases: An Update

Area of Science:

• Nutritional Science
• Cardiology
• Endocrinology

Background:

• Vitamin D is essential for calcium metabolism, bone health, immune function, and cell processes.
• Vitamin D is primarily synthesized via sunlight exposure, with dietary and supplemental sources also available.
• Vitamin D deficiency (VDD) is increasingly recognized as a potential risk factor for cardiovascular diseases (CVDs), including heart disease and stroke.

Purpose of the Study:

• To review current evidence on the association between vitamin D levels and cardiovascular diseases.
• To explore whether low vitamin D is a cause or consequence of CVD.
• To discuss implications for anesthesia considerations in patients with VDD.

Main Methods:

• Systematic review of existing scientific literature.
• Analysis of epidemiological studies and clinical trials.
• Synthesis of data regarding vitamin D status and cardiovascular outcomes.

Main Results:

• Low blood vitamin D levels are correlated with an increased risk of developing CVDs.
• The causal relationship between vitamin D levels and CVD remains uncertain.
• Some evidence suggests vitamin D supplements may reduce CVD risk, but further investigation is required.

Conclusions:

• The link between vitamin D and cardiovascular health warrants further investigation.
• Clarifying the role of vitamin D in CVD pathogenesis is crucial.
• Understanding this association may inform clinical practice, including anesthesia management.
