Key result
Right bundle branch block in patients with acute myocardial infarction was associated with a statistically significant increase in 3-year mortality compared to patients without intraventricular conduction disturbances.
Why the study?
Does the presence of right bundle branch block worsen prognosis and increase mortality in patients with acute myocardial infarction?
Cohort (n=190)
Does the presence of right bundle branch block worsen prognosis and increase mortality in patients with acute myocardial infarction?
Answers are grounded in this paper and cite their sources.
Right bundle branch block in the setting of acute myocardial infarction is a marker of poor long-term prognosis and increased mortality, suggesting multivessel coronary disease.
The study analyzes the influence on the prognosis of blockade of the right bundle branch block in patients with acute myocardial infarction. Score the prognostic value of blockade of the right bundle branch block was carried out in comparison with a group of patients without intraventricular conduction disturbances, and a group of patients with left bundle branch block. Established negative prognostic effect of blockade of the right bundle branch block in patients with acute myocardial infarction, and this negative effect was maintained after 30 days a year, 3 years.

Molyanova et al. (2012) conducted a cohort in Acute myocardial infarction (n=190). Right bundle branch block vs. No intraventricular conduction disturbances was evaluated on 3-year mortality. Right bundle branch block in patients with acute myocardial infarction was associated with a statistically significant increase in 3-year mortality compared to patients without intraventricular conduction disturbances.
