Key result
Primary PCI without on-site surgical backup yields similar in-hospital mortality compared to on-site surgery.
Why the study?
Data on the in-hospital outcomes of primary PCI performed at hospitals with and without on-site cardiac surgery were lacking in Japan.
Does primary PCI performed at hospitals without on-site cardiac surgery result in different in-hospital mortality in AMI patients compared to hospitals with on-site cardiac surgery?
Observational (n=1,785)
Yes

Odds Ratio: 1.359 (95% CI 0.939–1.968)

Primary PCI for acute myocardial infarction can be performed at hospitals without on-site cardiac surgery with in-hospital mortality rates comparable to those at hospitals with on-site surgical backup.
No takes yet. Share an insight, caveat, or question.
Comparable in-hospital mortality supports primary PCI feasibility without on-site surgery in Japan; leaves open need for prospective validation.
Shiraishi et al. (2007) conducted an observational in Acute myocardial infarction (n=1,785). Primary PCI at hospitals without on-site CABG surgery vs. Primary PCI at hospitals with on-site CABG surgery was evaluated on In-hospital mortality (OR 1.359, 95% CI 0.939-1.968, p=0.1041). Primary percutaneous coronary intervention performed at hospitals without on-site cardiac surgery resulted in similar in-hospital mortality compared to hospitals with on-site surgery (10.5% vs 9.9%, adjusted OR 1.359, p=0.1041).
