In this study, we hypothesized that a soluble proprotein convertase subtilisin/kexin type 9 (PCSK9), soluble bone morphogenetic protein 4 (BMP-4), soluble E-selectin (sE-selectin), soluble endoglin (sENG) and soluble endocan (Endocan) would differ from healthy controls in myocardial infarction (MI) patients admitted to the hospital without any previous history of cardiovascular disease and with no cardioprotective drugs taken before admission. This evidence concerns the gene ESM1 and myocardial infarction.
