Early Effects of Atorvastatin on Vitamin D and Parathyroid Hormone Serum Levels Following Acute Myocardial Infarction

Objective: High Vitamin D serum level after acute myocardial infarction (aMI) has shown to increase cardiac reconstruction by increasing cell survival and enhancing angiogenesis. Atorvastatin has a well‐defined role in both primary and secondary prevention of cardiovascular diseases. It is suggested that this effect may partly be attributable to raising 25‐hydroxyvitamin D concentrations. The aim of this study was to evaluate atorvastatin effects on Vitamin D and parathyroid hormone (PTH) levels early after aMI. Methods: All patients admitted with aMI in Imam Reza Hospital, Mashhad, Iran, from July 2014 to March 2015, were included in this pre‐ and postintervention study. Serum levels of Vitamin D and PTH were measured on admission and the 3rd day after administration of atorvastatin 80 mg/day. Findings: A total of 69 post‐aMI patients (47 males and 22 females) were enrolled in this study. Serum levels of Vitamin D and PTH were significantly higher (23.52 ng/ml and 46.04 pg/ml, respectively) after 72 h of atorvastatin therapy compared to the baseline (19.66 ng/ml and 31.19 pg/ml, respectively) (P = 0.004 and 0.002, respectively). Conclusion: The early post‐aMI beneficial effects of atorvastatin can be attributed to increased serum Vitamin D level; however, atorvastatin cannot significantly decrease serum PTH level after aMI. Further studies are needed to elucidate the clinical effect of atorvastatin.
