“…CAD-RADS category, a standardized method for describing a wide range of CCTA data related to the occurrence, severity, and composition of coronary atherosclerosis, can be used to stratify patients with stable or acute chest pain. 16 To date, several studies have demonstrated that CAD-RADS had significantly prognostic value for MACEs and diagnostic performance for coronary artery disease. 3 , 4 , 17 Bittner et al 3 reported that traditional coronary stenosis severity (HR, 3.82–9.62; all P <0.001), high-risk plaque (HR, 2.61; P <0.001), and CAD-RADS 1-5 (HR, 2.43–21.84; all P <0.05) were all associated with MACEs for patients with stable chest pain.…”

Background: Pericoronary adipose tissue (PCAT) and Coronary Artery Disease Reporting and Data System (CAD-RADS) category had prognostic values for major adverse cardiovascular events (MACEs). However, little is known about the difference between CAD-RADS and PCAT computed tomography (CT) attenuation for predicting MACEs. This study was to compare the prognostic value of PCAT and CAD-RADS for MACEs in patients with acute chest pain. Methods: Between January 2010 and December 2021, all consecutive emergency patients with acute chest pain referred for coronary computed tomography angiography were enrolled in this retrospective study. MACEs included unstable angina requiring hospitalization, coronary revascularization, nonfatal myocardial infarction, and all-cause death. Patients’ clinical characteristics, CAD-RADS, and PCAT CT attenuation were used to evaluate risk factors of MACEs using multivariable Cox regression analysis. Results: A total of 1313 patients were evaluated (mean age, 57.13±12.57 years; 782 men). During a median follow-up of 38 months, 142 of the 1313 patients (10.81%) experienced MACEs. Multivariable Cox regression analysis showed that CAD-RADS categories 2, 3, 4, 5 (hazard ratio range, 2.286–8.325; all P <0.005) and right coronary artery PCAT CT attenuation (hazard ratio, 1.033; P =0.006) were independent predictors of MACEs after adjusting for clinical risk factors. The C statistics revealed that CAD-RADS improved risk stratification compared with PCAT CT alone (C-index, 0.760 versus 0.712; P =0.036). However, the benefit of right coronary artery PCAT CT attenuation combined with CAD-RADS was not significant compared with CAD-RADS alone (0.777 versus 0.760; P =0.129). Conclusions: Right coronary artery PCAT CT attenuation and CAD-RADS were independent predictors of MACEs. However, no incremental prognostic value of right coronary artery PCAT CT attenuation beyond CAD-RADS was detected for MACEs in patients with acute chest pain.
