Fibrinolytic Therapy in Patients with Acute ST-elevation Myocardial Infarction

Area of Science:

• Cardiology
• Emergency Medicine
• Pharmacology

Background:

• ST-elevation myocardial infarction (STEMI) requires timely reperfusion therapy.
• Primary percutaneous coronary intervention (PCI) is the gold standard, but not always accessible.
• Fibrinolytic agents offer an alternative reperfusion strategy for STEMI.

Purpose of the Study:

• To outline the role of fibrinolytic therapy in STEMI management.
• To emphasize the importance of primary PCI as the preferred strategy.
• To guide clinical decisions regarding fibrinolysis, its failure, and subsequent management.

Main Methods:

• Review of current guidelines and clinical evidence for STEMI reperfusion.
• Discussion of therapeutic options including primary PCI and fibrinolysis.
• Emphasis on timing and recognition of treatment failure.

Main Results:

• Primary PCI is the preferred reperfusion strategy for most STEMI patients.
• Fibrinolytic therapy is indicated when timely primary PCI is unavailable.
• Rescue PCI should be considered for fibrinolytic therapy failure.
• Coronary angiography and revascularization should be delayed for 3 hours post-fibrinolysis.

Conclusions:

• Fibrinolytic therapy remains an important reperfusion option for STEMI when primary PCI is not timely.
• Prompt identification of fibrinolytic failure and consideration of rescue PCI are essential.
• A 3-hour window post-fibrinolysis is recommended before angiography/revascularization.
