Vitamin D and cardiovascular disease risk

Area of Science:

• Cardiology
• Endocrinology
• Nutritional Science

Background:

• Cardiovascular disease (CVD) is the leading cause of death in the US.
• Emerging nontraditional risk factors are being investigated for early CVD detection and prevention.
• 25-hydroxyvitamin D deficiency is a potential novel CVD risk factor.

Purpose of the Study:

• To review the association between 25-hydroxyvitamin D levels and cardiovascular disease risk.
• To explore the potential role of vitamin D in CVD development.

Main Methods:

• Literature review of studies examining 25-hydroxyvitamin D levels and CVD.
• Analysis of associations with traditional CVD risk factors and events.

Main Results:

• Low 25-hydroxyvitamin D levels correlate with hypertension, obesity, diabetes mellitus, and metabolic syndrome.
• Deficiency is associated with cardiovascular events like stroke and congestive heart failure.
• Vitamin D deficiency may contribute to CVD development, possibly via diabetes or hypertension.

Conclusions:

• Vitamin D deficiency is easily screened and treated with supplementation.
• Larger observational studies and randomized trials are necessary to establish the benefit of vitamin D supplementation in reducing CVD events and mortality.
