Clinical outcome of new-onset atrial fibrillation after emergency percutaneous coronary intervention for myocardial infarction

Atrial fibrillation (AF), the most frequently sustained arrhythmia with an increasing incidence due to the ageing population [1], is common in the setting of acute myocardial infarction (AMI) with a reported incidence of 6% to 21% [2]. Compared with ventricular tachyarrhythmias, severe heart failure, or sudden cardiac arrest, AF has been regarded as a benign, transient, and self-limited and not a critical event during AMI. However, AF, in particular new-onset AF (NOAF), which is defined as AF rhythm without previous history before AMI occurrence, has been associated with higher rates of adverse events and mortality [3-6].
