Background: Recently vitamin D has received great interests for its multiple effects on inflammatory system and potential role in atherothrombosis. Coronary artery disease (CAD) is one of the common causes of death and disability in developed countries. Experimental evidence points to the involvement of multiple factors in coronary plaque formation, including vitamin D. The study aimed to examine the association of coronary artery disease with vitamin D level.

Methods: 140 patients of CAD (coronary artery disease) and 101 age and sex matched control were enrolled in the study and 25-hyroxyvitamin D (25(OH)D) concentration was measured. All participants were evaluated for presence of conventional risk factors for coronary artery disease. Association of vitamin D level was established after adjusting other risk factors using logistic regression analysis.

Results: In our study vitamin D level is significantly lower in patient group (CAD patients) compared with control group (18.2±10.9 vs 28.8±21ng/mL). Vitamin D deficiency was present in 81.4% patient in CAD patients whereas 57.7% in control group. Vitamin D deficiency was found to be an independent predictor of CAD after adjusting effect of other risk factors like hypertension, diabetes, smoking, obesity, high blood cholesterol and level of physical activity with adjusted odds ratio (95% confidence interval) 2.695 (1.148-6.330).

Conclusions: In present study patients of coronary artery disease had significantly low level of vitamin D as compared to individual without coronary artery disease. Vitamin D deficiency was found to be an independent predictor of CAD after adjusting other risk factors emphasizing that vitamin D can be a potential risk factor for development of coronary artery disease.
