Abstract

Vitamin D is known to affect the contractility of the heart, vascular tone and cardiac collagen content and tissue metabolism. A strong correlation exists between vitamin D deficiency and the pathogenesis of cardiovascular diseases. Scientific data indicates that raising vitamin D levels to normal can substantially reduce the elevated cardiovascular risk associated with this deficiency. Measurement of vitamin D levels is readily available and supplementation is easy. Vitamin D deficiency is present in approximately 30% to 50% of the general population. Our study reveals that an unusually high number (91.2%) of patients being treated in a cardiologist’s office exhibit low levels of vitamin D. This high prevalence in this cohort may be partly related to a high latitude location, a significant presence of African Americans and associated factors like diuretic use and obesity. Given the strong association between vitamin D deficiency and cardiovascular disease, this data is of utmost clinical importance.
