Key result
In patients with recurrent acute myocardial infarction undergoing primary percutaneous coronary intervention, having ≥2 diseased vessels or a diseased left main trunk was an independent predictor of in-hospital mortality (OR 2.673).
Why the study?
Does primary percutaneous coronary intervention (PCI) for recurrent myocardial infarction have different predictors of in-hospital mortality compared to primary PCI for first myocardial infarction?
Observational (n=1,785)
Yes
Does primary percutaneous coronary intervention (PCI) for recurrent myocardial infarction have different predictors of in-hospital mortality compared to primary PCI for first myocardial infarction?
Odds Ratio: 2.673 (95% CI 1.029–6.944)
p-value: p=0.0435
In patients undergoing primary PCI for recurrent AMI, multivessel or left main disease is an independent predictor of in-hospital mortality, suggesting that infarct-related artery-only PCI may be insufficient for this high-risk group.
No takes yet. Share an insight, caveat, or question.
Multivessel or left main disease may flag higher in-hospital mortality risk during recurrent AMI PCI; hypothesis-generating for whether complete revascularization improves outcomes.
Shiraishi et al. (2008) conducted an observational in Acute myocardial infarction undergoing primary percutaneous coronary intervention (n=1,785). Number of diseased vessels ≥2 or diseased left main trunk (LMT) vs. <2 diseased vessels was evaluated on In-hospital mortality in recurrent AMI patients (OR 2.673, 95% CI 1.029-6.944, p=0.0435). In patients with recurrent acute myocardial infarction undergoing primary percutaneous coronary intervention, having ≥2 diseased vessels or a diseased left main trunk was an independent predictor of in-hospital mortality (OR 2.673).
