B-type natriuretic peptide predicts new-onset atrial fibrillation in patients with ST-segment elevation myocardial infarction treated by primary percutaneous coronary intervention

► BNP was measured in 180 patients with STEMI treated by primary PCI. ► ROC analysis identified the best BNP cut-off value for prediction AF (≥720 pg/mL). ► BNP predicts the occurrence of new-onset AF in STEMI patients treated by primary PCI.
