Association of Vitamin D with Risk Factors for Coronary Artery Disease

Area of Science:

• Cardiovascular Medicine
• Endocrinology
• Nutritional Science

Background:

• Vitamin D plays a role in cardiovascular health by modulating inflammation and atheroma development.
• This study investigated the relationship between vitamin D levels, coronary artery disease (CAD), and associated risk factors like diabetes and lipid profiles.
• Coronary angiogram data and biochemical markers were analyzed in patients presenting with cardiac symptoms.

Discussion:

• Vitamin D deficiency was prevalent and associated with a higher incidence of diabetes mellitus and triple-vessel disease.
• Lower vitamin D levels correlated significantly with elevated HbA1c and increased severity of CAD, particularly triple-vessel disease.
• The study highlights vitamin D deficiency as a potential risk factor for both single and triple-vessel CAD.

Key Insights:

• Patients with vitamin D levels below 20 ng/mL showed a higher prevalence of diabetes mellitus and triple-vessel disease.
• Multivariable analysis indicated a significant association between vitamin D levels and the severity of CAD.
• A significant negative correlation was observed between HbA1c levels and vitamin D, and between vitamin D and triple-vessel disease.

Outlook:

• Further research is warranted to explore the causal relationship between vitamin D deficiency and CAD progression.
• Investigating the impact of vitamin D supplementation on cardiovascular outcomes in deficient individuals is crucial.
• Clinical guidelines may benefit from incorporating vitamin D assessment in the management of patients with cardiovascular risk factors.
