Key result
Young adult patients with acute myocardial infarction undergoing primary percutaneous coronary intervention had a significantly lower 30-day major adverse clinical outcome rate compared to older patients (12.3% vs 28.6%, p<0.001).
Why the study?
Does young age affect clinical outcomes in patients with ST-segment elevation AMI undergoing primary PCI compared to older patients?

Young-adult patients with ST-elevation AMI undergoing primary PCI have a favorable prognostic outcome with significantly lower 30-day major adverse clinical outcomes compared to older patients.

May inform age-based risk stratification in STEMI PCI; extends observational cohorts but remains hypothesis-generating.
Chen et al. (2009) conducted a cohort in ST-segment elevation acute myocardial infarction (AMI) (n=338). Young age vs. Older age (≥55 years) was evaluated on 30-day major adverse clinical outcome (MACO), defined as advanced congestive heart failure (NYHA class ≥3) or 30-day mortality (p=<0.001). Young adult patients with acute myocardial infarction undergoing primary percutaneous coronary intervention had a significantly lower 30-day major adverse clinical outcome rate compared to older patients (12.3% vs 28.6%, p<0.001).
