In the subgroup who reverted to AF, there was no difference in CRP (4.25 ± 4.71 vs. 3.85 ± 3.99; p = 0.776) or fibrinogen (3.93 ± 1.06 vs. 3.77 ± 1.38; p = 0.733) before and after the procedure; similarly, amongst those who maintained SR, there was no difference in either CRP (3.35 ± 4.42 vs. 5.1 ± 7.95; p = 0.158) or fibrinogen (4.28 ± 1.21 vs. 3.75 ± 1.08; p = 0.089) before and after the procedure.
