Persistent RBBB signals high in-hospital mortality after primary stenting for AMI; hypothesis-generating and requires prospective validation before guiding care.
Does the presence of persistent or transient right bundle branch block (RBBB) affect clinical outcomes in patients with acute myocardial infarction treated with primary PTCA and stenting?
In patients with acute myocardial infarction undergoing primary PTCA and stenting, persistent RBBB is associated with significantly higher in-hospital mortality and heart failure compared to transient or no RBBB.
