Objective: A growing body of research indicates that there exists a correlation between Vit D deficiency and cardiovascular diseases (CVD). In addition to being genetically determined, it is strongly influenced by lifestyle factors. In this study, Vit D and its interrelated factors have been studied as profile marker for identifying the risk of CVD in patients. Methods: The present study includes comparison of a total 200 adults CVD patients with the healthy patients as control, by measuring their serum lipid levels and Vit D concentrations with other CVD risk factors. Results: The average serum Vit D in CVD patients and controls are found to be 22.55±6.2 ng/ml and 37.62±3.2 ng/ml respectively, showing that 63% of CVD patients and 35% of controls are Vit D deficient. Serum lipids levels were considered as marker for patients having CVD which include high levels of total cholesterol, triglycerides, and low-density lipoprotein-cholesterol while low levels of high-density lipoproteins-cholesterol levels. Other risk factors like hypertension, lifestyle, smoking, dietary factors and nutritional status shows significantly correlation for CVD patients compared to controls. Conclusion: Literature supports the relationship between lipid profile and Vit D level by using this as a profile marker for CVD patients. Our study also suggests the same that vitamin D can be used as profile marker for cardiovascular diseases.
