Aim Interleukin (IL)-17 pathway is being clinically targeted in immune-mediated diseases, most of which are associated with a significant cardiovascular risk. We investigated the relationship between serum levels of IL-17 and the risk of cardiovascular events in patients with acute myocardial infarction. Methods and results We used data from 981 patients enrolled in the prospective, multicentre French registry of Acute ST elevation, or non-ST-elevation Myocardial Infarction (Fast-MI, NCT00673036). Serum levels of IL-17 were associated with the risk of all-cause death and recurrent MI at 2 years, with levels of IL-17 below the median indicative of a worse outcome. The impact of IL-17 remained significant after adjustment for known cardiovascular risk factors, C-reactive protein, and treatments including statins: hazard ratio (HR) = 1.40 (1.03-1.91); P = 0.03. IL-17 inhibited mononuclear cell adhesion to endothelium and reduced endothelial vascular cell adhesion molecule (VCAM-1) expression. Patients with low (below the median) IL-17 levels and high (above the median) soluble VCAM-1 (sVCAM-1) levels were at particularly increased risk of death and MI: adjusted HR = 2.22 (1.32-3.75) compared with the high IL-17/low sVCAM-1 group (P = 0.002). Conclusions Low serum levels of IL-17 are associated with a higher risk of major cardiovascular events in Caucasian patients with acute MI. Our results raise possible concern about the use of inhibitors of the IL-17 pathway in clinical settings associated with a high cardiovascular risk.
