Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Non-inferiority of the OCT-guided PCI compered to IVUS guided PCI in terms of target vessel failure (TVF) at a median follow-up of 1.5 years after randomization in the study population. - TVF is defined as composite time-to-first event rate of cardiac death, target vessel* myocardial infarction, or ischemia-driven target vessel revascularization (ID-TVR). *Target vessel: vessels treated for both the culprit lesion of AMI and a non-culprit lesion (planned to be treated within 3 months from the index PCI). | — |
Secondary
| Measure | Time frame |
|---|---|
| Clinical outcomes 1)Individual components of primary endpoint 2)All-cause death 3)Cardiac and non-cardiac death 4)Any myocardial infarction 5)Definite/probable stent thrombosis (ARC definition) 6)Stroke 7)Any revascularization 8)ID-revascularization and non-ID-revascularization 9)ID-TVR, ID-TLR and ID-non-TLR TVR 10)Bleeding 11)Relationship between post-PCI OCT/IVUS parameters and clinical endpoint rates Procedure outcomes 1)Achievement rate of TIMI grade 3 flow 2)Rate of achieving optimal imaging criteria 3)Rate of stentless procedure 4)Imaging performance success Safety outcomes 1)Contrast induced nephropathy 2)Procedure time, fluoroscopy time, radiation dose, and quantity of contrast medium 3)Imaging related or non-related procedural complications (coronary perforation, coronary dissection, distal embolization, side branch occlusion, ventricular fibrillation or tachycardia during procedure, stroke during procedure). | — |
