Randomized Controlled Trial Multicenter Study
Importance of persistent elevation of cardiac biomarkers in atrial fibrillation: a RE-LY substudy.
To evaluate the prognostic importance of transient or persistent elevations of cardiac troponin-I (cTnI) and N-terminal-B-type natriuretic peptide (NT-proBNP) in atrial fibrillation (AF). ⋯ Persistent elevation of troponin and NT-proBNP indicates a worse prognosis than transient elevations or no elevations of either marker. Prognostication of stroke, death and thromboembolic events is improved by the use of repeated determinations of cardiac biomarkers.
