The role of soluble adhesion molecules as predictors of MACE and further adverse outcomes in patients submitted to PCI has been previously hypothesized.7 Our finding of prognostic ability of sICAM‐1 and MMP‐9 confirms the clinical usefulness of biomarkers of inflammation and vascular repair in the outcomes of patients with ischaemic heart disease submitted to PCI. Here, MMP9 is linked to heart disorder.
