Identification of the three-gene signature for patients with myocardial infarction (MI) in the GSE66360 data set. (a, b) Eight differentially expressed genes (DEGs) were identified by least absolute shrinkage and selection operator (LASSO) regression. (c, d) Line plot of 5-fold cross-validation of the support vector machine recursive feature elimination (SVM-RFE) algorithm for feature selection. (e) Venn diagram of LASSO and SVM-RFE. (f) Three DEGs were identified by using the SignalP 3.0 server. (g)The three-gene signature was identified by multivariable logistic regression
