Key result
PCI linked to ~68% lower in-hospital mortality in elderly patients with AMI.
Why the study?
The status of percutaneous coronary intervention (PCI) and the reasons for not receiving PCI in elderly patients with acute myocardial infarction (AMI) needed investigation.
Does percutaneous coronary intervention reduce in-hospital mortality in elderly patients (≥80 years) with acute myocardial infarction?
Population
387 consecutive hospitalized AMI patients aged ≥80 years
Comparison
PCI treatment vs no PCI treatment
Design
Cohort study

Supports selective PCI use in elderly AMI patients; leaves open causality and generalizability pending randomized trials.
Cohort (n=387)
Does percutaneous coronary intervention reduce in-hospital mortality in elderly patients (≥80 years) with acute myocardial infarction?
Odds Ratio: 0.323 (95% CI 0.147–0.71)
p-value: p=.005
PCI is associated with significantly reduced in-hospital mortality in AMI patients aged ≥80 years, though utilization remains low due to comorbidities and delayed presentation.
Chen et al. (2019) conducted a cohort in Acute myocardial infarction (AMI) (n=387). Percutaneous coronary intervention (PCI) vs. Not receiving PCI was evaluated on In-hospital mortality (OR 0.323, 95% CI 0.147-0.710, p=.005). Percutaneous coronary intervention was an independent protective factor for in-hospital mortality in elderly patients with acute myocardial infarction (OR 0.323; 95% CI 0.147-0.710; P=0.005).
