Blood biomarkers useful for improving stroke risk prediction in AF
Higher concentrations of the blood biomarkers cystatin C, factor VIII, interleukin (IL)‐6, and N‐terminal B‐type natriuretic peptide (NT‐proBNP), are strongly associated with increased risk of stroke in atrial fibrillation (AF), according to data from the REGARDS* study. Moreover, these markers improve the prediction of stroke risk when added to the CHA2DS2VASc score.
