For STEMI, what is the recommended door-to-balloon time for reperfusion therapy?

• A. Within 90 minutes
• B. Within 24 hours
• C. Within 2 hours
• D. Within 1 hour

Answer: (A)

In STEMI, restoring blood flow quickly minimizes heart muscle damage, so the speed of getting the patient to reperfusion is crucial. Door-to-balloon time is the interval from the patient’s arrival to inflation of the balloon during PCI. The recommended target is ninety minutes or less, because shorter times are consistently linked with lower mortality and fewer complications. While some centers strive for even faster times, ninety minutes remains the standard benchmark for timely PCI. Times longer than this delay reperfusion and worsen outcomes, whereas shorter times meet the guideline.
