In a recent study on 981 patients with acute myocardial infarction, low serum levels of IL-17 combined with high serum levels of the leukocyte adhesion molecule vascular cell adhesion molecule 1 (VCAM-1) was associated with a higher risk of major cardiovascular events, while patients with high IL-17 and low VCAM-1 had better outcomes [9]. Here, IL17A is linked to acute myocardial infarction.
