Key result
Lower preoperative serum 25(OH) vitamin D levels independently predicted the development of new-onset atrial fibrillation after coronary artery bypass grafting surgery (OR 0.95).
Why the study?
Does preoperative vitamin D deficiency increase the risk of new onset atrial fibrillation after CABG surgery?

Odds Ratio: 0.95 (95% CI 0.91–0.99)
p-value: p=0.035
Preoperative vitamin D deficiency is independently associated with an increased risk of developing new-onset atrial fibrillation following CABG surgery.
Emren et al. (2016) conducted an observational in New onset atrial fibrillation after coronary artery bypass grafting (CABG) (n=283). Serum 25(OH) vitamin D levels vs. Higher vitamin D levels was evaluated on New onset postoperative atrial fibrillation (POAF) (OR 0.95, 95% CI 0.91-0.99, p=0.035). Lower preoperative serum 25(OH) vitamin D levels independently predicted the development of new-onset atrial fibrillation after coronary artery bypass grafting surgery (OR 0.95).
