What is the best initial management step for a patient with suspected ACS who is already on dual antiplatelet therapy and develops active bleeding?

• A. Continue dual antiplatelet therapy
• B. Hold anticoagulant/antiplatelet therapy as indicated and assess bleeding source; activate ACS protocol once stabilized.
• C. Immediately reverse with protamine
• D. Proceed with immediate coronary intervention without addressing bleeding

Answer: (B)

In this scenario, safety first means stopping ongoing bleeding before pushing further antithrombotic or invasive cardiac therapies. The best initial step is to hold anticoagulant and antiplatelet therapy as indicated, identify and control the source of bleeding, and stabilize the patient. Only after bleeding is addressed and the patient is hemodynamically stable should the ACS plan be pursued. Continuing dual antiplatelet therapy would worsen bleeding, and rushing to immediate coronary intervention without controlling hemorrhage can be dangerous. Reversal with protamine is only applicable for heparin effects and does not address all antiplatelet drugs, and proceeding to urgent PCI without first addressing bleeding ignores the immediate life-threatening problem.
