Data extraction
During 24 h after late PCI (for late PCI group) and 24 h after ICCU admission (for No Revas group), the laboratory test of MMP-9, NOX2, and TGF-β1 was done for each four groups which measured by Enzyme-linked Immunosorbent Assays (ELISA) (BT Laboratory™) method using 3 cc blood vein sample from the patients in each group. The laboratory tests of MMP-9, NOX2, and TGF-β1 all performed in the Laboratory of Physiology, Animal Structure and Development, Molecular Biology Building (Biomol), Faculty of Mathematics and Natural Sciences, Brawijaya University, Indonesia. After preparing all the reagents needed for each marker, 40 µl blood sample for each marker and 10 µl antibody (anti-MMP-9, anti-NOX2, and anti- TGF-β1) were added in the plate for each marker, and then 50 µl streptavidin-HRP was mixed into each plate. After that 50 µl A substrate, 50 µl B substrate, and 50 µl stop solution were added in each plater. The absorbance was measured using 450 nm spectrofluorometry. About 5 days after treatment, the second laboratory test of MMP-9, NOX2, and TGF- β1 was done again for each four groups. The standard laboratory test including Hemoglobin, leukocyte, thrombocyte, blood urea nitrogen, creatinine serum, aspartate transaminase, alanine transaminase, and troponin were immediately tested for all of the patients.
