CRP and Paroxysmal atrial fibrillation: We thus conducted the present study to investigate (1) the postprocedural behavior of PACs evaluated by Holter monitoring, (2) CK-MB and TnT as markers of myocardial injury, and (3) CRP as a marker of inflammation on the day after CB ablation for paroxysmal AF, and we compared the results with those of patients who underwent RF ablation.
