Atrial Fibrillation Impairs the Diagnostic Performance of Cardiac Natriuretic Peptides in Dyspneic Patients: Results From the BACH Study (Biomarkers in ACute Heart Failure)

Study Questions:

What is the effect of atrial fibrillation (AF) on the diagnostic performance of mid-region amino terminal pro-atrial natriuretic peptide (MR-proANP), in comparison to B-type natriuretic peptide (BNP) and N-terminal pro-BNP (NT-proBNP), in patients enrolled in the BACH (Biomarkers in Acute Heart Failure) trial?
