Objectives

Narrative objectives1

The aims of the study are (1) to evaluate the prevalence and pattern of layered plaques both at culprit and non-culprit lesions using optical coherence tomography (OCT) in a prospective fashion, and (2) to identify biomarkers and microbiome specific for layered plaque to better understand the underlying pathobiology.

Key inclusion criteria

Patients with SAP or ACS who are undergoing catheterization would be eligible. ACS include ST elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI), and unstable angina pectoris. When thrombus interferes with optimal OCT image acquisition, aspiration thrombectomy will be allowed.

Key exclusion criteria

- Previous revascularization at the culprit vessel
- Tortuous vessel
- Heavily calcified vessel
- Chronic Kidney Disease (estimated glomerular filtration rate < 30 mL/min per
1.73 m2)
- Cardiogenic shock

Results

Bacteria that were associated with vulnerable coronary plaque phenotype and greater plaque burden were identified. These bacteria were also associated with elevated inflammatory or prothrombotic biomarkers.

Baseline Characteristics

Patients who underwent both optical coherence tomography and intravascular ultrasound imaging and provided stool and blood specimens were included.

Participant flow

After informed consent is obtained, patients will undergo standard coronary angiography with or without PCI, which will be performed at the discretion of the interventionalist. In Japan, IVUS is performed in almost all PCI cases. OCT imaging of the target vessel will be performed prior to PCI. After the procedure, IVUS and OCT will be repeated.

Adverse events

none

Outcome measures

All OCT and IVUS images were submitted to the Massachusetts General Hospital core laboratory. OCT and IVUS image analysis was performed using offline review workstations (Ilumien Optis) (QCU CMS RESEARCH version 4.69, Leiden University Medical Center, Leiden, the Netherlands) by investigators who were blinded to the clinical, angiographic, and laboratory data.
The composition of gut microbiota was evaluated using 16S rRNA sequencing.

Other related information

This study is designed as a prospective observational investigation. The data will be collected prospectively from a single site (New Tokyo Hospital, Chiba, Japan). One hundred patients undergoing clinically indicated cardiac catheterization will be enrolled. Informed consent will be obtained from each patient prior to the procedure. OCT imaging of the target vessel will be performed prior to intervention. Patient demographic information, angiograms, IVUS images and OCT images will be sent to Massachusetts General Hospital for analysis.
