Which of the following is a primary method of reperfusion for STEMI?

• A. Calcium channel blocker therapy
• B. Aspirin only without intervention
• C. Statin therapy
• D. Primary percutaneous coronary intervention

Answer: (D)

The essential idea is restoring blood flow to the heart muscle as quickly as possible in a STEMI. The best way to achieve this is a primary percutaneous coronary intervention, a catheter-based procedure that mechanically opens the blocked coronary artery and often places a stent. This direct, rapid reperfusion method improves survival and limits heart muscle damage when it can be done promptly. Calcium channel blocker therapy doesn’t restore the blocked artery and thus isn’t a reperfusion strategy in this context; it mainly affects heart rate and vascular tone rather than reopening the occluded vessel. Aspirin alone, while helpful as an antiplatelet agent to reduce further clotting, does not reestablish blood flow by itself. Statin therapy targets long-term cholesterol management and plaque stabilization, not immediate reperfusion of an acute occlusion. When PCI isn’t available in a timely window, pharmacologic reperfusion with thrombolytics is an alternative, but that’s separate from the primary method identified here.
