After coronary stenting, what determines the duration of dual antiplatelet therapy?

• A. The patient’s age alone.
• B. The stent type and clinical scenario.
• C. Operator preference alone.
• D. Vessel size alone.

Answer: (B)

The length of dual antiplatelet therapy after coronary stenting is set by the type of stent used and the patient’s clinical situation. Different stents heal at different rates and carry different risks of stent thrombosis; drug-eluting stents delay endothelial healing more than bare-metal stents, so they typically require a longer period of dual antiplatelet therapy. The clinical scenario also matters: if the patient had an acute coronary syndrome or a complex, high-risk PCI, the thrombotic risk is higher and longer therapy may be favored; if there’s a high bleeding risk, upcoming surgery, or other factors increasing bleeding or medication interactions, shorter durations may be chosen. Age, vessel size, or operator preference alone don’t reliably determine how long dual antiplatelet therapy should continue.
