GAS6 and hyperlipidemia: Univariate analysis revealed that, the Gas6/AXL complex, sAXL, Gas6, hyperlipidemia, left ventricular ejection fraction (LVEF), white blood cells (WBC), neutrophil percentage, blood glucose, alanine transaminase (ALT), aspartate transaminase (AST), low_density lipoprotein (LDL), high density lipoprotein (HDL) and brain natriuretic peptide (BNP) were significantly associated with STEMI (p < 0.05), while other factors were not statistically significant (p > 0.05).
