Vitamin D deficiency is highly prevalent worldwide, and is also noted to be high in India. Low levels of 25(OH) D, the principle circulating storage form of vitamin D, is present in as many as one third to one half of otherwise healthy middle aged to elderly population. Endothelial dysfunction plays an important role in pathogenesis of CAD and vitamin D deficiency is postulated to promote endothelial dysfunction.

To estimate vitamin D levels in IHD patients, 2) To correlate vitamin
