Key result
Complete atrioventricular block in acute coronary syndrome was an independent predictor of hospital mortality (OR 3.671; P=0.045), with no significant difference at one-year follow-up.
Why the study?
Does complete atrioventricular block worsen outcomes in patients with acute coronary syndrome?
Population
4,799 patients admitted with acute coronary syndrome
Comparison
Presence of complete atrioventricular block (n=91) vs Absence of complete atrioventricular block

Does complete atrioventricular block worsen outcomes in patients with acute coronary syndrome?
Odds Ratio: 3.671
p-value: p=0.045
Complete atrioventricular block complicating acute coronary syndrome is associated with a nearly 4-fold increased risk of in-hospital mortality and higher rates of cardiogenic shock and ventricular arrhythmias.
Rosa et al. (2017) conducted a cohort in acute coronary syndrome (n=4,799). Complete atrioventricular block vs. Without complete atrioventricular block was evaluated on Hospital mortality (OR 3.671, p=0.045). Complete atrioventricular block in acute coronary syndrome was an independent predictor of hospital mortality (OR 3.671; P=0.045), with no significant difference at one-year follow-up.
