Pericoronary adipose tissue (PCAT) attenuation by computed tomography angiography has emerged as a marker specific for coronary artery inflammation. We examined the relationship between clinical presentation and coronary artery inflammation assessed by PCAT attenuation and coronary plaque characteristics.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods:<\/jats:title>\n            <jats:p>Patients with ACS or stable angina pectoris (SAP) who underwent preintervention coronary computed tomography angiography and optical coherence tomography were enrolled. PCAT attenuation was measured around the culprit lesion and in the proximal 40 mm of all coronary arteries. PCAT attenuation and optical coherence tomography findings were compared between patients with ACS versus SAP.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>\n              Among 471 patients (ACS: 198, SAP: 273), PCAT attenuation was higher in ACS patients than in SAP patients both at the culprit plaque level (\u221267.5\u00b19.6 Hounsfield unit [HU] versus \u221271.5\u00b111.0 HU,\n              <jats:italic toggle=\"yes\">P&lt;<\/jats:italic>\n              0.001) and at the culprit vessel level (\u221268.3\u00b17.7 HU versus \u221271.1\u00b17.9 HU,\n              <jats:italic toggle=\"yes\">P&lt;<\/jats:italic>\n              0.001). The mean PCAT attenuation of all 3 coronary arteries was also significantly higher in ACS patients than in SAP patients (\u221268.8\u00b16.3 HU versus \u221270.5\u00b17.1 HU,\n              <jats:italic toggle=\"yes\">P<\/jats:italic>\n              =0.007).
