In STEMI when PCI is not immediately available, what pharmacologic reperfusion option may be considered?

• A. Heparin infusion
• B. Mechanical thrombectomy
• C. Antiplatelet therapy only
• D. Fibrinolytic therapy

Answer: (D)

In STEMI, restoring blood flow as quickly as possible is essential. When PCI isn’t available promptly, dissolving the clot with drugs that break down fibrin is the pharmacologic reperfusion option. Fibrinolytic therapy uses agents that convert plasminogen to plasmin to dissolve the thrombus blocking the coronary artery, helping to restore perfusion and limit heart muscle damage. This approach is most effective the earlier it’s given, ideally within the first hours after symptom onset, and is often chosen when PCI cannot be performed within a recommended time window. After fibrinolysis, transferring the patient for PCI when feasible is common (a pharmacoinvasive approach). It’s important to remember that these drugs carry a bleeding risk and aren’t used in patients with certain contraindications. Other options like heparin alone, mechanical thrombectomy, or antiplatelet therapy without a clot-busting agent do not provide the same rapid reperfusion effect.
