[Acute intervention for ST-elevation myocardial infarction]

Area of Science:

• Cardiology
• Interventional Cardiology
• Emergency Medicine

Background:

• Modern therapy for ST-elevation myocardial infarction (STEMI) prioritizes rapid revascularization for all patients.
• A significant proportion of STEMI patients receive medical treatment, including thrombolysis, either prehospital or in-hospital.

Observation:

• Timely invasive diagnosis and revascularization, such as percutaneous intervention (PCI) or coronary artery bypass graft (CABG), are essential.
• Primary PCI, when performed promptly by experienced interventional cardiologists in specialized centers, represents the optimal management strategy for STEMI.
• Transfer PCI is a viable treatment for patients initially admitted to facilities lacking PCI capabilities, aiming for completion within 90 minutes of transfer.

Findings:

• Rescue PCI following unsuccessful thrombolysis (less than 50% ST-segment resolution 90 minutes post-thrombolysis) significantly improves patient prognosis by restoring coronary blood flow.
• When immediate planned PCI post-thrombolysis is not feasible, PCI initiated shortly after high-dose glycoprotein IIb/IIIa inhibitors and clopidogrel can yield favorable results.

Implications:

• Optimizing treatment pathways for STEMI, including timely PCI and effective transfer protocols, is critical for improving patient outcomes.
• The study highlights the importance of experienced interventional teams and specialized centers for delivering the best care in STEMI management.
• Alternative strategies involving rescue PCI and pharmacoinvasive approaches provide valuable options when primary PCI is not immediately accessible.
