Background: Cardiac accidents due to Coronary Artery Disease are the most common cause of mortality in the world. On the other hand, vitamin D deficiency is known as an emerging risk factor of this disease. Considering the high prevalence of vitamin D deficiency in Iran we investigated the prevalence of vitamin D deficiency in angioplasty patients, effect of gender and its relationship with Coronary Artery Disease severity.
Materials and Methods: In this cross sectional study serum level of 25(OH) D3 in was measured in 149 patients undergoing PCI between May and September 2013 in Baqiatallah hospital. Patients with renal failure (Cr>2mg/dl), liver disease, and those treated with glucocorticoids or anti-epileptic drugs were excluded. Data were analyzed with SPSS 21 software. Chi-square and T-Test were used and P value<0.05 was considered statistically significant.
Results: The prevalence of vitamin D deficiency in patients was 77.2% (men 86% and women 62.5%) (p=0.0005). Vitamin D deficiency severity was related to the number of involved vessels in men (p=0.046). Vitamin D deficiency was related with stent length in patients with right coronary angioplasty (p=0.041).
Conclusion: The effect of vitamin D deficiency on coronary artery disease seems to be different in men and women. Complementary studies are needed to elucidate this issue further.
