Objective: Smoking is an established stimulant of TNF-alpha. We aimed to investigate whether TLA1 plays a role in the presence and complexity of coronary artery atherosclerosis, exclusively in non-smoking patients with CAD. Methods: We enrolled 103 participants in the study, who underwent coronary angiography for stable angina pectoris. We divided the study population into 2 groups: The CAD group consisted of 62 patients with CAD and the control group consisted of 41 subjects with non-CAD. SYNTAX and Gensini scores, indicating CAD severity and complexity, were analysed as well as TLA1 levels. Results: TLA1 levels was higher in patients with CAD than those in controls (228[119-824] vs 178[15-418]pg/ml, p < 0.001). Presence of CAD (beta +/- SE = 106.29 +/- 33.11, p = 0.002), Syntax score (beta +/- SE= 6.57 +/- 1.75, p = 0.012), and Gensini score (beta +/- SE = 2.30 +/- 0.65, p = 0.001) were found to be predictors of TL1A levels. Gensini score and Syntax score were positively correlated with TL1A levels (r = 0.420, p < 0.001, and r = 0.402, p < 0.001, respectively). Conclusions: Non-smoker CAD patients have higher TLA1 levels that are promising biomarker for diagnosing CAD and indicating CAD lesion complexity.en10.1080/1354750X.2019.1685004info:eu-repo/semantics/closedAccessTumour necrosis factor ligand superfamily member 15atherosclerosiscoronary artery diseasegensini scoringsyntax scoringTnf-Like LigandCirculating LevelsDecoy Receptor-3Up-RegulationSmokingTl1aInflammationCorrelateImpactAlphaArticle248764770Q3WOS:0004940611000012-s2.0-8507463087731646918Q2
