The outcomes mentioned were presented as follows: myocardial infarction size, left ventricular ejection fractions (LVEF), left ventricular fraction shortening (LVFS), left ventricular end diastolic dimension (LVDd), left ventricular end systolic dimension (LVSd), lactate dehydrogenase (LDH), creatine kinase (CK), CK-MB, superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), malondialdehyde (MDA), myeloperoxidase (MPO), nuclear factor kappa B (NF-κB), tumor necrosis factor alpha (TNF-a), cardiac fibrosis area. This evidence concerns the gene MPO and myocardial infarction.
