MMP9 and infarction: Various genes and ncRNAs have been found reliable in assessing inflammation, apoptosis, myocardial remodeling, and lipid metabolism, including NR4A2 (nuclear receptor subfamily 4 group a member 2), IRAK3 (interleukin-1 receptor-associated kinase 3), IL1R2 (interleukin 1 receptor type 2), CLEC4E (C-type lectin domain family 4 member E), MMP9 (matrix metallopeptidase 9), and TNF (tumor necrosis factor), with high levels in post-infarction samples [124,125,126,127].
