There was no significant difference in the CRP level after ablation, but the troponin-T level and body temperature were higher in the AF group than those in the control group (troponin-T: 1.1 [0.9–1.3] vs 0.2 [0–0.3] ng/L, P < 0.001; body temperature: 37.3 ± 0.4 vs 36.9 ± 0.5 °C, P < 0.001, respectively) (Table 2). Here, CRP is linked to atrial fibrillation.
