New-onset RBBB signals higher long-term mortality and shock risk in AMI; leaves open whether targeted monitoring or intervention improves outcomes.
Does new-onset RBBB increase the risk of adverse outcomes in patients with acute myocardial infarction compared to previous RBBB?
New-onset RBBB in AMI patients is associated with increased risks of long-term mortality, ventricular arrhythmia, and cardiogenic shock compared to previous RBBB, supporting the consideration of revascularization therapies in these patients.
