The combination of EATV, EAT-CT attenuation, and PCAT-RCA-FAI predicted postoperative atrial fibrillation (AUC=0.880) and graft occlusion (AUC=0.814) after coronary artery bypass grafting.
Does the combination of EATV, EAT-CT attenuation, and PCAT-FAI predict postoperative atrial fibrillation and graft occlusion in patients undergoing CABG?
The combined assessment of epicardial and pericoronary adipose tissue parameters on preoperative CCTA significantly improves risk stratification for postoperative atrial fibrillation and graft occlusion in patients undergoing CABG.
Absolute Event Rate: 0% vs 0%
Objective: To evaluate the predictive value of epicardial adipose tissue volume (EATV), EAT-CT attenuation, and pericoronary adipose tissue fat attenuation index (PCAT-FAI) for postoperative atrial fibrillation (POAF) and graft occlusion after coronary artery bypass grafting (CABG). Methods: In this single-center retrospective study, 83 patients undergoing CABG with preoperative CCTA were enrolled. EATV, EAT-CT attenuation, pericoronary adipose tissue volume (PCAT volume), and PCAT-FAI were measured. Multivariate logistic regression and ROC analysis were used to assess their predictive performance. Results: During a 13-month follow-up, 20.4% developed POAF and 39.8% had graft occlusion. The combination of EATV, EAT-CT attenuation, and PCAT-RCA-FAI predicted POAF with an AUC of 0.880, superior to any single parameter. It also showed improved prediction for graft occlusion (AUC=0.814). Conclusion: EATV, EAT-CT attenuation, and PCAT-RCA-FAI provide complementary predictive value for POAF and graft occlusion after CABG. Combined use improves preoperative risk stratification and supports clinical decision-making.
