MMP8 and myocardial infarction: As previous studies already documented that neutrophils play an essential role in tissue remodelling after several tissue injures and after MI, we now measured effects of STS treatment on blood levels of neutrophils‐derived granule components, including neutrophil elastase, myeloperoxidase, proteinase 3, neutrophil gelatinase‐associated lipocalin (NGAL), MMP‐8 and MMP‐9, in both groups of patients following MI.15 Peripheral blood obtained from patients just at the enrolment and after 5‐day treatment with either STS or saline were measured using ELISA with indicated antibodies.
