Key result
In patients with acute inferior STEMI undergoing primary PCI, the presence of complete atrioventricular block did not significantly increase in-hospital mortality, and the block resolved in 66.6% of affected patients.
Why the study?
Complete atrioventricular block is associated with poor clinical outcomes in STEMI, motivating an evaluation of the frequency and outcomes of primary percutaneous coronary intervention in patients with CAVB complicating acute inferior STEMI.
Does the presence of complete atrioventricular block (CAVB) affect in-hospital mortality in patients with acute inferior STEMI undergoing primary percutaneous coronary intervention (PPCI)?
Population
151 patients diagnosed with inferior STEMI receiving PPCI
Comparison
Patients with CAVB vs without CAVB
Design

May not worsen in-hospital mortality after primary PCI; leaves open need for prospective data on long-term outcomes and management.

Does the presence of complete atrioventricular block (CAVB) affect in-hospital mortality in patients with acute inferior STEMI undergoing primary percutaneous coronary intervention (PPCI)?
Absolute Event Rate: 9.5% vs 2.3%
p-value: p=>0.05
Primary PCI is effective in reverting complete atrioventricular block in acute inferior STEMI, resulting in in-hospital mortality comparable to patients without heart block.
Malik et al. (2020) conducted an observational in Acute inferior ST-elevation myocardial infarction (n=151). Complete atrioventricular block (CAVB) vs. No CAVB was evaluated on In-hospital mortality (p=>0.05). In patients with acute inferior STEMI undergoing primary PCI, the presence of complete atrioventricular block did not significantly increase in-hospital mortality, and the block resolved in 66.6% of affected patients.
