Myocardial untargeted metabolomics and amino acids related metabolites profiles among four mice groups. A, B Principal component analysis (PCA) score plots of adult control (Group A, Aadcon), adult AF (Group B, BadAF), aged control (Group C, Cagcon), and aged AF (Group D, DagAF) in A positive ion mode and B negative ion mode. C Hierarchical clustering heatmap of amino acids and related metabolites profile of four groups in positive ion mode. n = 10 in each group
