In STEMI management, which therapy is recommended within 30 minutes of arrival?

• A. Beta-blockers
• B. Thrombolytics
• C. Antibiotics
• D. Diuretics

Answer: (B)

Restoring blood flow quickly is the aim in STEMI, and when primary PCI isn’t available right away, giving thrombolytic therapy within 30 minutes of arrival (door-to-needle time) is the recommended approach. Thrombolytics dissolve the occlusive clot in the coronary artery, minimizing myocardial damage and reducing mortality when reperfusion is achieved promptly. Beta-blockers are useful after initial stabilization and are not the immediate 30-minute reperfusion therapy. Antibiotics aren’t part of STEMI management unless there’s a concurrent infection, and diuretics are used for volume overload or heart failure, not for rapid reperfusion.
