Background

Acute myocardial infarction in young adults is an increasing clinical concern due to changing lifestyle patterns, rising tobacco use, obesity, diabetes, dyslipidemia, and premature atherosclerosis. Primary percutaneous coronary intervention (PCI) is the preferred reperfusion strategy for ST-elevation myocardial infarction (STEMI). However, young patients undergoing primary PCI differ from older populations in risk factors, angiographic characteristics, procedural outcomes, and long-term prognosis.

Objective

This study evaluates the clinical outcomes of young patients undergoing primary PCI, focusing on risk profile, angiographic findings, procedural success, complications, major adverse cardiovascular events, and long-term prognosis.

Methods

A narrative review and comparative clinical analysis were conducted using published studies, registry reports, and guideline-based evidence from interventional cardiology literature.

Results

Young patients undergoing primary PCI generally demonstrate high procedural success rates, lower in-hospital mortality, and better short-term survival compared with older patients. However, recurrent ischemic events, medication non-adherence, smoking relapse, and uncontrolled metabolic risk factors remain major determinants of long-term outcomes.

Conclusion

Primary PCI is highly effective in young STEMI patients, but long-term prognosis depends on aggressive secondary prevention, lifestyle modification, risk factor control, and structured follow-up.
