In humans, an acute myocardial infarction registry demonstrated that serum IL-17A below a median of 6.26 pg/mL was associated with higher risk for all-cause mortality and recurrent myocardial infarction, but many patients had IL-17A levels below the assay’s detection limit of 2.5 pg/mL [141]. Here, IL17A is linked to acute myocardial infarction.
