Permanent atrial fibrillation (AF) appears to be the only form of AF that independently predicts death among patients with acute myocardial infarction (AMI) who are treated invasively. When compared with a control group, more than half of AMI patients with permanent AF (54.3%) had significantly higher long-term mortality. The long-term mortality rate for new-onset AF was 35.8%.
