Objectives

Narrative objectives1

The objective of this study is to investigate the association between pericoronary adipose tissue attenuation (PCAT attenuation) obtained from coronary computed tomography angiography (cCTA) and the temporal changes in plaque characteristics assessed by optical coherence tomography (OCT).

Assessment

Primary outcomes

Based on previous reports, patients are classified into two groups: the High PCAT attenuation group, defined as having a PCAT attenuation of -75 HU or higher, and the Low PCAT attenuation group, defined as having a PCAT attenuation of less than -75 HU. The change in fibrous cap thickness of the target lesion observed by OCT is compared between these two groups.

Key inclusion criteria

Patient Criteria
Patients who underwent follow-up coronary angiography (CAG) and optical coherence tomography (OCT) at least 3 months and within 24 months after baseline CAG and OCT.
Patients who underwent coronary computed tomography angiography (cCTA) within 5 months prior to baseline CAG and OCT.
Patients aged 20 years or older at the time of baseline CAG and OCT.
Lesion Criteria
Lesions with plaque showing a luminal area stenosis between 30% and 70% on baseline OCT evaluation.

Key exclusion criteria

Patients with stent placement in the proximal right coronary artery (<10 mm) or the left main coronary artery.
Patients with a history of coronary artery bypass grafting (CABG).
Patients for whom cCTA analysis is not feasible.
Patients for whom OCT analysis is not feasible.
Lesion Criteria
Lesions treated with percutaneous coronary intervention (PCI) at the time of baseline CAG and OCT (including within 5 mm of the treated segment).
