What is the recommended time frame for performing PCI after first medical contact?

• A. Within 120 minutes of first medical contact
• B. Within 6 hours of symptom onset
• C. Within 24 hours
• D. Within 90 minutes from door to balloon time

Answer: (A)

Rapid reperfusion is essential in STEMI, and the goal is to minimize the time from first medical contact (EMS or any initial evaluation) to revascularization. The recommended target for PCI is within 120 minutes from first medical contact. This accounts for prehospital activation and fast transport to a cath lab, ensuring the artery is opened as quickly as possible to limit heart muscle damage. The alternative of 90 minutes from door to balloon refers to hospital arrival to PCI time, a related but different metric that doesn’t account for delays before reaching the hospital. The other options—6 hours after symptom onset or 24 hours—are far beyond the optimal window for PCI in STEMI and miss the critical early reperfusion period.
