Abstract 11040: Not Carotid but Femoral Artery Intima-Media Thickness Predicts Peripheral Artery Disease in Patients With Coronary Artery Disease

Background: Numerous studies reported the clinical and prognostic significance of carotid artery intima-media thickness (IMT) in atherosclerotic disease patients. However, clinical significance of femoral artery IMT was not fully elucidated. Femoral artery IMT may have unique clinical significance in patients with coronary artery disease (CAD). Purpose: We examined the relationship among carotid and femoral artery IMT, the presence of PAD, and risk factors in fully medically treated patients with CAD. Methods: Patients (n = 192; mean age 71.8±10.4 years) who were diagnosed by coronary angiography were enrolled. PAD was defined as ABI < 0.9. Using ultrasound echo, the mean common carotid and femoral artery IMT were evaluated. We evaluated the diagnostic value of the carotid and femoral artery IMT for PAD. To determine the cutoff value of IMT for prediction of PAD, we used a receiver operating characteristic (ROC) analysis. Furthermore, we examined the differences of risk factors for the increased IMT in bo...
