Key result
Patients with acute myocardial infarction who experienced out-of-hospital cardiopulmonary arrest had significantly higher rates of acute anteroseptal infarction (72% vs 53%) and prior myocardial infarction (32% vs 12%) compared to those without arrest.
Observational (n=698)
No
Absolute Event Rate: 72% vs 53%
p-value: p=0.016
Out-of-hospital cardiac arrest in AMI is strongly associated with prior MI, pre-infarction angina, and acute anteroseptal infarction, while bystander CPR significantly improves the rate of return to society.
May flag higher arrest risk in anteroseptal/prior-MI AMI; leaves open whether targeted strategies improve outcomes.

Morita et al. (1999) conducted an observational in Acute myocardial infarction with out-of-hospital cardiopulmonary arrest (n=698). Out-of-hospital cardiopulmonary arrest vs. Admitted alive without cardiopulmonary arrest was evaluated on Acute anteroseptal myocardial infarction (p=0.016). Patients with acute myocardial infarction who experienced out-of-hospital cardiopulmonary arrest had significantly higher rates of acute anteroseptal infarction (72% vs 53%) and prior myocardial infarction (32% vs 12%) compared to those without arrest.
