CRP and atrial fibrillation: A meta-analysis on this topic found that a lower post-procedural elevation of myocardial injury biomarkers and increased CRP levels post-procedure may be predictive factors for AF recurrence.26 So far, there is only few data on inflammation parameters and the characteristics of myocardial injury biomarker release after PFA.27,28 However, PFA lesions are homogeneous with a preserved tissue architecture and are reported to be associated with less tissue inflammation than thermal ablation in animal models29,30 .
