State of the Art of Primary PCI: Present and Future

Area of Science:

• Cardiology
• Interventional Cardiology

Background:

• Primary percutaneous coronary intervention (PCI) has significantly advanced ST-elevation myocardial infarction (STEMI) management.
• Despite improvements, STEMI prognosis is still limited by cardiac death and heart failure (HF), with stagnant mortality rates.

Purpose of the Study:

• To review current primary PCI practices and identify factors influencing STEMI patient outcomes.
• To explore future therapeutic targets, particularly microvascular dysfunction, for improving STEMI prognosis.

Main Methods:

• Review of current literature on primary PCI for STEMI.
• Analysis of factors affecting patient outcomes post-PCI.
• Exploration of emerging strategies targeting microvascular function and ischemia-reperfusion injury.

Main Results:

• Primary PCI remains the cornerstone of STEMI treatment, but outcomes are plateauing.
• Microvascular dysfunction is a critical, under-recognized factor contributing to adverse outcomes like HF and mortality.
• Strategies to preserve microvascular function and reduce infarct size are key therapeutic frontiers.

Conclusions:

• Addressing microvascular dysfunction is crucial for improving long-term STEMI prognosis.
• Personalized interventions targeting ischemia-reperfusion injury and infarct size are needed.
• Further research into microvascular protection may break the deadlock in STEMI mortality rates.
