Key result
Left bundle branch block was associated with significantly higher in-hospital mortality (18.2% vs 6.7%, p=0.008) compared to no left bundle branch block in patients with congestive heart failure.
Why the study?

Absolute Event Rate: 18.2% vs 6.7%
p-value: p=0.008
In patients with heart failure, the presence of LBBB is associated with significantly higher disease severity and increased in-hospital mortality.
No takes yet. Share an insight, caveat, or question.
LBBB may identify higher-risk HF inpatients for closer monitoring; leaves open whether it independently predicts mortality or warrants targeted intervention.
Bouqata et al. (2014) conducted an observational in Congestive heart failure (n=220). Left bundle branch block (LBBB) vs. No left bundle branch block was evaluated on In-hospital mortality (p=0.008). Left bundle branch block was associated with significantly higher in-hospital mortality (18.2% vs 6.7%, p=0.008) compared to no left bundle branch block in patients with congestive heart failure.
