Initial univariate analysis of the training cohort (n = 195) identified multiple significant predictors of AF recurrence (all p < 0.05), including AF type (non‐paroxysmal vs paroxysmal), diabetes mellitus, advanced age, LVZ extent, RDW, hs‐CRP, and increased LAD (Table 2). The gene discussed is CRP; the disease is atrial fibrillation.
