Which therapy is used as a reperfusion option in STEMI aside from PCI?

• A. Beta blockers
• B. Anticoagulants
• C. ACE inhibitors
• D. Fibrinolytics

Answer: (D)

Reperfusion in STEMI can be achieved by opening the blocked artery mechanically with PCI or by dissolving the clot pharmacologically when PCI isn’t available quickly. Fibrinolytics are this pharmacologic option. They activate plasminogen to plasmin, which breaks down the fibrin in the clot and restores blood flow to the affected heart muscle. This approach is most effective when given as soon as possible after symptom onset, especially if PCI cannot be performed within the recommended time window. Fibrinolytics are chosen when timely PCI isn’t feasible, typically within the first hours after symptoms begin, to limit heart muscle damage and improve outcomes. They do carry a notable risk of bleeding, including intracranial hemorrhage, so contraindications must be carefully considered. Other drugs like beta blockers, ACE inhibitors, or anticoagulants have important roles in STEMI management, but they do not directly re-open the blocked coronary artery. They support heart protection, remodeling, and ongoing prevention, rather than serving as the immediate reperfusion method.
