The results showed that compared with healthy controls, SARS-CoV-2 receptors, including Transmembrane Serine Protease 2 (TMPRSS2, P = 0.009) and Glutamyl Aminopeptidase (ENPEP, P = 0.012), were significantly upregulated in CAD (Fig. 5b). This evidence concerns the gene TMPRSS2 and coronary artery disorder.
