ALB and atrial fibrillation: Serum total protein and albumin levels remained significantly high in the control, MK, LAB, AF + LAB, and AF/LAB groups compared to the AF group (p < 0.010), whereas serum total bilirubin levels significantly decreased in control (p < 0.001), MK (p < 0.010), LAB (p < 0.010), AF + LAB (p < 0.010), and AF/LAB (p < 0.010) groups in comparison to the AF group (Table 4).
