Key result
High-degree atrioventricular block was independently associated with increased in-hospital mortality in patients with anterior STEMI (HR 19.264), but not in those with inferior STEMI.
Why the study?
Does high-degree atrioventricular block increase in-hospital mortality in STEMI patients treated with primary PCI?
Population
16,536 STEMI patients treated with primary percutaneous coronary intervention
Comparison
Presence of high-degree atrioventricular block vs Absence of high-degree atrioventricular block
Design
Cohort
Follow-up
In-hospital

High-degree AV block flags high-risk anterior STEMI for closer monitoring; leaves open whether targeted interventions alter outcomes.
Observational (n=17,046)
Yes
Does high-degree atrioventricular block increase in-hospital mortality in STEMI patients treated with primary PCI?
Hazard Ratio: 19.264 (95% CI 5.804–63.936)
p-value: p=<0.001
In the era of primary PCI, high-degree atrioventricular block is an independent predictor of in-hospital mortality in anterior STEMI, but its negative prognostic impact in inferior STEMI is no longer prominent.
Kim et al. (2016) conducted an observational in ST-segment elevation myocardial infarction (STEMI) (n=17,046). High-degree atrioventricular block (HAVB) vs. No HAVB was evaluated on In-hospital mortality (multivariate analysis for anterior STEMI) (HR 19.264, 95% CI 5.804-63.936, p=<0.001). High-degree atrioventricular block was independently associated with increased in-hospital mortality in patients with anterior STEMI (HR 19.264), but not in those with inferior STEMI.
