Why the study?
The study aimed to investigate the potential relationship between preoperative vitamin D levels and the development of atrial fibrillation after cardiac surgery.
Do preoperative vitamin D levels affect the development of postoperative atrial fibrillation in adult patients undergoing cardiac surgery?
Do preoperative vitamin D levels affect the development of postoperative atrial fibrillation in adult patients undergoing cardiac surgery?
Low preoperative vitamin D levels are significantly associated with an increased risk of developing atrial fibrillation after cardiac surgery.
May identify at-risk cardiac surgery patients; confirms association but leaves causality and supplementation benefit open for RCTs.
