Ankle Brachial Index Intensifies the Diagnostic Accuracy of Epicardial Fat Thickness for the Prediction of Coronary Artery Disease Complexity

Objectives Epicardial fat thickness (EFT) and Ankle brachial index (ABI) are associated with coronary artery disease (CAD). The SYNTAX score (SS) reflects the complexity of CAD. We aimed to evaluate the relation of EFT and ABI with CAD complexity. Methods We enrolled 197 patients undergoing coronary angiography. In all patients, ABI and EFT were determined. SS was calculated. The relationship between EFT, ABI and SS was analysed. Results ABI and EFT were significantly correlated with SS (r = -0.525, p < 0.001, and r = 0.650, p < 0.001, respectively) and found to be independent predictors of SS. ABI22 with a sensitivity of 45.28% and a specificity of %82.64 (AUC = 0.689, %95 CI = 0.619-0.763, p
