Heart failure patients with HFrEF and atrial fibrillation (HFrEF-AF) have higher NT-proBNP than HFrEF patients without atrial fibrillation (AF). This is thought to be a consequence of AF and not necessarily correlated with deleterious clinical outcomes.
HF clinical trials have stipulated different inclusion NT-proBNP levels for patients with HFrEF-AF. It turns out, a defined higher NT-proBNP level for patients with HFpEF-AF may not be necessary.
