Relationship between plasma level of Vitamin D and post operative atrial fibrillation in patients undergoing CABG

Abstract

Objective: Atrial fibrillation is the most common arrhythmia after cardiac surgery. Several studies have shown the impact of vitamin D on heart disease; however, there have been few studies for the incidence of AF and its relationship with vitamin D levels. According to the different results of these studies, we decided to evaluate the relation of plasma levels of vitamin D and postoperative atrial fibrillation in patients undergoing coronary artery bypass surgery (CABG).

Methods: This cross-sectional study was performed on 50 patients after CABG surgery. Simple random sampling was done. Twenty five patients who developed AF within 48 hours after CABG with Cardiopulmonary bypass (CPB) were enrolled in the case group and 25 patients who did not develop AF within 48 hours after CABG with CPB were enrolled in the control group. Plasma levels of vitamin D in both groups of patients were recorded. Collected data were analyzed by the SPSS software version 17.

Results: There was no significant difference in terms of demographic characteristics, comorbidities, lipid profile and kidney function between two groups. The mean plasma level of vitamin D was 27.4 ± 2.22 ng/ml in the case group and was 28.2 ± 1.18 ng/ml in the control group it (p= 0.803).

Conclusions: Plasma levels of vitamin D were almost the same in both groups and there was no statistically significant difference between the groups with and without atrial fibrillation following CABG.
