CRP and Paroxysmal atrial fibrillation: They enrolled 263 paroxysmal AF patients and demonstrated that the serum hs-TnI level was significantly lower and the CRP level was significantly higher after PVI by the low-power long-duration (LPLD) RF strategy (maximum power: 30 W for 25 s) than that of the one by cryoballoon (CB) ablation (freeze time 180–240 s, applications for PVs: 6.0 ± 1.8).
