OCT-Guided Stent Optimization for Short-Duration Dual Antiplatelet Therapy in Stable Angina

Patients receive aspirin and clopidogrel for 1 month after PCI. After 1 month, aspirin is discontinued and clopidogrel monotherapy is continued.

Patients with high bleeding risk will receive aspirin and clopidogrel for 6 months after PCI (unoptimization confirmed in OCT), followed by single antiplatelet therapy thereafter.

Patients (with stet unoptimazation results in OCT imaging) receive aspirin and clopidogrel for 12 months after PCI.

All patients undergo percutaneous coronary intervention with mandatory intravascular imaging using optical coherence tomography to assess stent optimization (expansion, apposition, dissection).
