CRP and atrial fibrillation: Multivariate logistic regression model including baseline characteristics, myocardial injury and inflammation biomarker revealed that AF duration (OR = 1.220, p = 0.004), CRP at 24 h (OR = 1.019, p = 0.019) and CRP at 48 h (OR = 1.058, p = 0.035) were predictive of AER in RF group and CRP at 48 h (OR = 0.453, p = 0.023) was predictive of AER in CB group.
