CRP and atrial fibrillation: Various cardiac, renal function, coagulation, and inflammatory markers are being studied and some have shown improved risk stratification for ischemic stroke in AF patients.[18] However, there is lack of evidence to suggest CRP provides incremental predictive value for ischemic stroke incidence, although there has been no study that investigated reclassification improvement for ischemic stroke incidence by CRP in AF patients [18].
