Thrombolytic Treatment for Acute Anterior Wall Myocardial Infarction

Reperfusion Strategy Decision Algorithm

The European Society of Cardiology recommends that for patients with acute anterior wall myocardial infarction who cannot receive timely primary PCI, tenecteplase is the recommended fibrinolytic agent due to its fibrin specificity, ease of administration as a single bolus, and established efficacy in reducing mortality 1, 2
Confirm STEMI diagnosis with 12-lead ECG within 10 minutes of arrival, and determine time since symptom onset, according to the American Heart Association 2, 4, 1, 5
If primary PCI can be performed within 90-120 minutes of first medical contact, choose primary PCI, as recommended by the European Society of Cardiology 1, 2
If primary PCI cannot be performed within 120 minutes, administer fibrinolytic therapy within 30 minutes of arrival, as suggested by the American College of Cardiology 5, 3

Administer fibrinolytic therapy as soon as possible, ideally within 12 hours of symptom onset, according to the European Society of Cardiology 1, 2
The agent of choice is a fibrin-specific agent, such as tenecteplase, alteplase, or reteplase, as recommended by the American Heart Association 1, 2
Aspirin 150-325 mg should be administered orally or IV if unable to swallow, and clopidogrel loading dose followed by daily maintenance, as suggested by the European Society of Cardiology 1, 2
Anticoagulation with enoxaparin or unfractionated heparin should be used, according to the American College of Cardiology 1, 2

All patients should be transferred to a PCI-capable center immediately after fibrinolysis, as recommended by the European Society of Cardiology 1, 2
Continuous cardiac monitoring for arrhythmias and bleeding complications should be performed, according to the American Heart Association 4
Rescue PCI indications include failed fibrinolysis, hemodynamic or electrical instability, and recurrent ischemia, as suggested by the European Society of Cardiology 2
Timing of angiography if fibrinolysis is successful should be 2-24 hours after fibrinolysis, according to the American College of Cardiology 1, 2

Anterior MI is associated with a higher risk for left ventricular dysfunction and heart failure, increased risk for mural thrombus formation and embolic stroke, and greater likelihood of conduction disturbances and arrhythmias, as noted by the American Heart Association 4
Echocardiography should be performed to evaluate LV function and detect complications, according to the European Society of Cardiology 4

Delaying fibrinolysis should be avoided, and it should be administered within 30 minutes of arrival if primary PCI is not available within 120 minutes, as recommended by the American College of Cardiology 5, 3
Inadequate anticoagulation should be avoided, and anticoagulation should be continued until revascularization or for up to 8 days, according to the European Society of Cardiology 1
Missing the transfer window should be avoided, and all patients should be transferred to a PCI-capable center after fibrinolysis, as suggested by the American Heart Association 1, 2
Failing to recognize failed fibrinolysis should be avoided, and rescue PCI should be arranged immediately if needed, according to the European Society of Cardiology 2
