Patients who develop new-onset atrial fibrillation (AF) after acute myocardial infarction (AMI) show an increased risk for adverse events and mortality during follow-up. Recently, a novel noninvasive echocardiographic method has been validated for the estimation of total atrial activation time using tissue Doppler imaging of the atria (PA-TDI duration). PA-TDI duration has shown to be independently predictive of new-onset AF. However, whether PA-TDI duration provides predictive value for new-onset AF in patients after AMI has not been evaluated. Consecutive patients admitted with AMIs and treated with primary percutaneous coronary intervention underwent echocardiography
