Introduction: Over the years, the extraskeletal effects of Vitamin D (vit D) are gaining prominence. The role of vit D deficiency (VDD) in coronary artery disease (CAD) is conflicting. Hence, the present study was aimed to correlate serum vit D levels with high-sensitivity C-reactive protein (hs-CRP) and Gensini score in CAD individuals. Materials and Methods: This cross-sectional study was conducted on 70 angiographically proven CAD individuals aged between 35 and 55 years of both sexes who presented with a history of myocardial injury or ischemia for the first time. The angiographic findings were graded using Gensini score. Serum vit D and hs-CRP were estimated using enzyme-linked immunosorbent assay. Results: The average serum vit D level was 15 ng/mL, and the ratio of diabetes and nondiabetes individuals was 52:18. Among the 70 patients, 66% (n = 46) were deficient, 20% (n = 14) were insufficient, and 14% (n = 10) had normal vit D status. Although insignificant, vit D levels had negative correlation with Gensini score (r = −0.17, P = 0.14) and hs-CRP levels (r = −0.03, P = 0.77) which was not sustained after multivariate logistic regression. A significant negative correlation (r = −0.35, P = 0.01) was found between serum vit D status and duration of diabetes. Conclusion: VDD observed in diabetes individuals is inversely related to the duration of diabetes which incidentally is associated with CAD. Thus, screening for vit D status may be vital for the management of CAD particularly in diabetes individuals.
