Association between circulating 25-hydroxyvitamin D levels and medication use in patients scheduled for cardiac surgery

Abstract Background and aim Low vitamin D status, i.e. circulating 25-hydroxyvitamin D (25OHD) levels Methods and results A total of 11,256 patients were included in this cross-sectional study. We compared 25OHD levels of medication users (18 groups of continuously used and 5 groups of intermittently used medications) with levels of non-users. Moreover, we assessed variables (medications, demographic and clinical parameters) that were independently associated with 25OHD levels Conclusion Data indicate that in patients with high cardiovascular risk profile medication use does not substantially contribute to 25OHD levels
