BackgroundTNF-like cytokine 1A (TL1A)-mediated interactions are involved in atheromatic plaque formation. In stable coronary artery disease (CAD) we examined whether circulating TL1A levels correlate with coronary and/or peripheral atherosclerosis extent and predict future cardiovascular events.MethodsIn this cross-sectional study, peripheral vascular studies and TL1A serum measurements were performed in 122 consecutive patients with angiographically confirmed CAD who were followed for a median of 41.9 months. TL1A levels were compared against controls (n = 63) and 20 patients with acute coronary syndrome (ACS).ResultsTL1A was higher in ACS than the 2 other groups (p < 0.001). In stable CAD, after adjustment for traditional risk factors independent positive correlations between TL1A serum levels and reflected waves (p = 0.049), and carotid atheromatic plaque score (p = 0.049) were evident. In stable patients with a history of ACS, TL1A levels correlated with worse endothelial function (p = 0.006), extent of CAD assessed by Gensini score (p = 0.042), and cardiac mortality (p = 0.051).ConclusionsThis pilot study suggests that serum TL1A measurements are of clinical value in CAD. Studies on the pathogenetic role of TL1A in atherosclerosis and its sequelae are warranted.Copyright © 2014 Elsevier Ltd. All rights reserved.
