Insights
Primary percutaneous coronary intervention (pPCI) is the standard for ST-segment elevation myocardial infarction (STEMI). Despite advancements, outcomes plateau, with cardiac arrest and heart failure remaining significant challenges in STEMI patients.
Area of Science:
- Cardiology
- Interventional Cardiology
- Acute Coronary Syndromes
Background:
- Primary percutaneous coronary intervention (pPCI) has transformed ST-segment elevation myocardial infarction (STEMI) care.
- The widespread adoption of pPCI has led to increased center availability globally.
- Despite pPCI's success, clinical outcomes for STEMI patients have stagnated in recent years.
Purpose of the Study:
- To review current contentious issues in pPCI for STEMI patients.
- To highlight unresolved questions and persistent challenges in STEMI management.
- To provide an overview of areas requiring further evidence and optimization.
Main Methods:
- Literature review of current scientific evidence.
- Analysis of unresolved questions in STEMI treatment.
- Focus on contentious aspects of pPCI in STEMI.
Main Results:
- Outcomes in STEMI patients treated with pPCI have plateaued.
- In-hospital mortality remains high due to out-of-hospital cardiac arrest and cardiogenic shock.
- Long-term STEMI survivors face an increasing burden of heart failure.
Conclusions:
- Significant challenges persist in optimizing STEMI treatment despite pPCI.
- Further research is needed to address debated elements and improve clinical outcomes.
- Addressing cardiac arrest, cardiogenic shock, and heart failure is crucial for STEMI survivors.
Abstract:
Primary percutaneous coronary intervention (pPCI) has revolutionized the prognosis of ST-segment elevation myocardial infarction (STEMI) and is the gold standard treatment. As a result of its success, the number of pPCI centres has expanded worldwide. Despite decades of advancements, clinical outcomes in STEMI patients have plateaued. Out-of-hospital cardiac arrest and cardiogenic shock remain a major cause of high in-hospital mortality, whilst the growing burden of heart failure in long-term STEMI survivors presents a growing problem. Many elements aiming to optimize STEMI treatment are still subject to debate or lack sufficient evidence. This review provides an overview of the most contentious current issues in pPCI in STEMI patients, with an emphasis on unresolved questions and persistent challenges.
