The statistical significance (p-value) of the difference analysis (Mann–Whitney U test) and descriptive statistics of the transcriptional activity (number of RNA copies) of the metalloproteinase 9 (MMP-9) gene family and tissue inhibitor of metalloproteinases type 1 (TIMP-1) in patients with coronary angiography excluded coronary artery disease (A), patients with coronary artery disease without heart failure (B), and patients with coronary artery disease and heart failure (C) are presented in Table 5 and Table 6. This evidence concerns the gene TIMP1 and coronary artery disorder.
