VITAMIN D AND MYOCARDIAL INFARCTION...IS THE LINK REAL?

Background:Vitamin D has assumed even more importance in recent years because of its diversity of actions. One of the most recently discovered effects of vitamin D is on the vascular system, through which it can produce an impact on cardiovascular health. Multiple studies have been done in this regard, but it still requires further exploration. The objective of our study was to explore any existing association of vitamin D deficiency with myocardial infarction (MI) andto make a comparison of levels of vitamin D in patients with recent MI and healthy individuals. Material and Methods:A comparative cross-sectional study was carried out in the Cardiology Department of Shaikh Zayed Hospital and Punjab Institute of Cardiology. The study measured serum Vitamin D levels in64 participants belonging to two categories: patients with recent myocardial infarction and healthy controls. Serum vitamin D levels in both groups were compared. Results:showed Serum Vitamin D was sub-optimal in all study participants, including myocardial infarction patients and the healthy controls. A clear association between vitamin D deficiency and myocardial infarction could not be seen. Mean±SD Vitamin D levels were 18±7.8ng/L in myocardial infarction patients and 19.1±9.3ng/L in healthy individuals. This study did not establish an association between myocardial infarction and vitamin D levels. Conclusion:Our study failed to show a link between Vitamin D and myocardial infarction. Further exploration is needed in this regard.Key Words:Vitamin D, Myocardial Infarction, Hypertension
