AbstractBackground and Objectives: Angiopoietin-like protein 3 (ANGPTL3) is a secretory protein regulating lipid metabolism. This study evaluated the relationship between serum ANGPTL3 level and peripheral arterial stiffness (PAS) in patients with coronary artery disease (CAD). Materials and Methods: Fasting blood samples were collected from 95 CAD patients. PAS was defined as left or right brachial-ankle pulse wave velocity (baPWV) > 18.0 m/s by an oscillometric method. Serum ANGPTL3 levels were assessed using a commercial enzyme-linked immunosorbent assay kit. Results: Seventeen CAD patients (17.9%) had PAS. Patients with PAS had a significantly higher percentage of diabetes (p = 0.002), older age (p = 0.030), higher systolic blood pressure (p = 0.016), higher fasting glucose (p = 0.008), serum C-reactive protein (p = 0.002), and ANGPTL3 level (p = 0.001) than those without PAS. After multivariable logistic regression analysis, serum ANGPTL3 level (Odds ratio (OR): 1.004, 95% confidence interval (CI): 1.000-1.007, p = 0.041) is still independently associated with PAS in CAD patients. The receiver operating characteristic curve for PAS prediction revealed that the area under the curve for ANGPTL3 level was 0.757 (95% CI: 0.645-0.870, p < 0.001). Conclusions: Serum fasting ANGPTL3 level is positively associated with PAS in CAD patients. Further studies are required for clarification.
