BACKGROUND: Studies have shown that lipoprotein(a) Lp(a), an important carrier of oxidized phospholipids, is causally related to calcific aortic valve stenosis (CAVS). Recently, we found that Lp(a) mediates the development of CAVS through autotaxin (ATX). OBJECTIVE: To determine the predictive value of circulating ATX mass and activity for CAVS. METHODS: We performed a case-control study in 300 patients with coronary artery disease (CAD). Patients with CAVS plus CAD (cases, n = 150) were age- and gender-matched (1 : 1) to patients with CAD without aortic valve disease (controls, n = 150). ATX mass and enzymatic activity and levels of Lp(a) and oxidized phospholipids on apolipoprotein B-100 (OxPL-apoB) were determined in fasting plasma samples. RESULTS: , median) (OR 5.48, 95% CI 2.45-12.27, P < 0.0001) had an elevated risk of CAVS. CONCLUSION: Autotaxin is a novel and independent predictor of CAVS in patients with CAD.
