Atrial cardiomyopathy markers and new-onset atrial fibrillation risk in patients with acute myocardial infarction

•New-onset AF(NOAF) after acute myocardial infarction(AMI) is common and is associated with worse outcomes.•Atrial cardiomyopathy markers including PTFV1, LAD, and BNP were strongly associated with NOAF after AMI.•The prediction performance of the ESC model for NOAF was increased by the addition of these markers.
