Implication
New RBBB in AMI was associated with highest mortality and frequent occlusion; leaves open whether it merits primary PCI guideline status without randomized data.

Population
6,742 patients with acute myocardial infarction (AMI) admitted to eight participating hospitals
I
Intervention
Primary percutaneous coronary intervention (PCI)
C
Comparator
Patients with left bundle branch block (LBBB) or other electrocardiographic patterns
O
Outcome
Angiographic patterns (TIMI flow), primary angioplasty use, and in-hospital mortalityhard clinical
Acute myocardial infarction patients presenting with new right bundle branch block have high rates of complete coronary occlusion and the highest in-hospital mortality, suggesting it should be a guideline indication for primary PCI similar to LBBB.
