Novel Biomarker Identification for Acute Coronary Syndrome via Integrating WGCNA and Machine Learning.

ABSTRACT: Immune cells in early atherosclerotic lesions promote inflammation and acute coronary syndrome (ACS), but the precise link between inflammation and ACS progression is still unclear. In this study, we analysed mRNA and miRNA expression profiles of ACS from GEO, identifying 98 mRNAs and 627 miRNAs by differentially expressed analysis. GSEA revealed abnormal activation of immune- and inflammation-related pathways, such as T cell receptor signalling pathway and cell adhesion molecules cams. The biomarkers ARG1, HECW2, and PFKFB3 were identified through WGCNA, LASSO, and SVM-RFE. Diagnostic performance and miRNA-mRNA interaction network were performed using ROC curves and Cytoscape. CIBERSORT analysis revealed that the levels of CD4 memory resting T cells were downregulated, whereas monocytes a
