Here, we found upregulation of S100A8, S100A9, and CEBPD in PBMCs of stable coronary artery disease/myocardial infarction (sCAD/MI) cases, compared against controls (Figure 5A), together with a positive correlation of S100A8 and S100A9 expression with that of CEBPD in these cells (Figure 5B, C). Here, S100A8 is linked to myocardial infarction.
