There seems to be no difference in YKL-40 levels between MI patients with or without ST elevations, but higher YKL-40 levels were seen in thrombolyzed patients compared with non-thrombolyzed patients during the first 24 hours after the event [46] indicating that YKL-40 is released from the dissolved thrombosis. The gene discussed is CHI3L1; the disease is myocardial infarction.
