Brief summary
Intravascular ultrasound (IVUS) serves as a beneficial instrument during percutaneous coronary intervention (PCI) procedures, affording insight into lesion characteristics and stent implantation. The ULTIMATE trial recently evidenced that IVUS-guided Drug-Eluting Stent (DES) implantation notably ameliorated clinical outcomes in all-comers, especially in patients who underwent an optimal procedure defined by IVUS, as opposed to angiography guidance, resonating with findings from the IVUS-XPL study, OCTOBER trial, and RENOVATE COMPLEX PCI trial, further confirmed by more recent IVUS-ACS trial. Optical coherence tomography (OCT) has a resolution 10 times higher than that of IVUS and can provide valuable information at each step of PCI. Regrettably, a dearth of prospective, randomized, multicenter trials exists that scrutinize the benefits of IVI-guided as opposed to angiography-guided PCI in patients suffering from diabetes mellitus. However, several trials have presented subgroup analyses reporting the reduction of clinical events by IVUS but not OCT guidance in patients with diabetes mellitus, which served as the foundation for the design of this trial.
Detailed description
The current study hypothesizes that IVI-guided PCI will be superior with respect to target vessel failure (TVF), including cardiac death, target-vessel myocardial infarction (TVMI), or clinically-driven TVR when compared with angiography-guided PCI in patients with diabetes mellitus.
Interventions
Intravascular imaging including intravascular ultrasound or optical coherence tomography.
Deployment of a drug-eluting stent under angiography.

Study design
Masking description
Randomization will be performed in the catheter laboratory by an invasive nurse. Staff in the catheter laboratory will be not blinded to the treatment allocation.
Intervention model description
Patients will undergo 1:1 randomization to either intravascular imaging (including intravascular ultrasound or optical coherence tomography)-guided DES implantation which will be the treatment group or Angio-guided DES implantation which will be the control group, stratified by research sites.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Rate of target vessel failure (TVF) | At one-year since interventions | TVF is defined as a composite of cardiac death, target-vessel myocardial infraction, or clinically driven target vessel revascularization |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Rate of target vessel failure without procedure-related MI | At one-year since interventions | Procedural-related myocardial infarction (PMI) would be excluded from the calculation of TVF |
| Rate of cardiac death | At one-year since interventions | Any death without clear reasons |
| Rate of all-cause death | At one-year since interventions | Any death occurs within one-year follow-up |
| Rate of procedure-related myocardial infarction (PMI) | Within 48 h since coronary intervention | 48 hours after coronary intervention |
| Rate of spontaneous myocardial infarction (SMI) | Within one-year follow-up | MI happens between 48 h and one-year since coronary intervention |
| Rate of clinically-driven revascularization | At one-year since coronary artery intervention | Target vessel revascularization was defined as any repeat percutaneous intervention or surgical bypass of any segment of the target vessel. The target vessel was defined as the entire major coronary vessel proximal and distal to the target lesion, which included upstream and downstream branches and the target lesion itself. |
| Rate of stent thrombosis | At one-year since coronary artery intervention | Definite or probable stent thrombosis |
