When PCI is not immediately available, which reperfusion option is commonly used for STEMI?

• A. Fibrinolytics
• B. Beta blockers
• C. Calcium channel blockers
• D. Aspirin monotherapy

Answer: (A)

When PCI isn’t available right away, the immediate goal is to restore blood flow to the blocked coronary artery. Fibrinolytics are used for this reperfusion purpose because they dissolve the clot that’s causing the STEMI, helping to reopen the vessel quickly. They’re given intravenously and are most effective when used within a specific time window from symptom onset. This approach contrasts with other options listed: beta blockers and calcium channel blockers mainly reduce heart workload or control blood pressure and do not dissolve the blockage, while aspirin helps prevent new clots but does not re-open the blocked artery by itself. So, dissolving the clot with fibrinolytics is the appropriate reperfusion strategy when PCI isn’t immediately available.
