Key result
AMI during unprotected left main PCI is linked to ~25% lower 1-year survival versus non-AMI.
Why the study?
Does the presence of acute myocardial infarction at presentation reduce 30-day and 1-year survival in patients undergoing PCI for unprotected left main coronary artery stenosis?

Presentation with acute myocardial infarction is associated with significantly higher 30-day and 1-year mortality in patients undergoing unprotected left main coronary artery stenting.
Darrat et al. (2012) conducted a cohort in Unprotected left main coronary artery stenosis (n=64). Acute myocardial infarction at presentation vs. Absence of acute myocardial infarction was evaluated on 1-year survival (p=0.04). Presentation with acute myocardial infarction during unprotected left main PCI was associated with significantly lower 1-year survival compared to non-AMI presentation (45.2% vs 70.2%; P=0.04).
