Prognostic value of new-onset right bundle-branch block in acute myocardial infarction patients: a systematic review and meta-analysis.

ABSTRACT:

Background

Patients with acute myocardial infarction (AMI) and bundle-branch block have poor prognoses. The new European Society of Cardiology guideline suggests a primary percutaneous coronary intervention strategy when persistent ischemic symptoms occur in patients with persistent ischemic symptoms and right bundle-branch block (RBBB), but the level of evidence is not high. In fact, the presence of RBBB may lead to the misdiagnosis of transmural ischemia and mask the early diagnosis of ST-elevation myocardial infarction. Moreover, new-onset RBBB is occasionally caused by AMI. Our study aims to investigate the prognostic value of new-onset RBBB in AMI.

Methods and results

We conducted a meta-analysis of studies to evaluate the prognostic value of RBBB in AMI patients. Of 91
