The Gut Microbiota and Seleno-Compound as Emerging Risk Factors for Acute Myocardial Infarction

Abstract Background It has been seemed that the gut microbiome alterations might be proposed as the metabolic disorder. However, the relationship between the microbiome and AMI has not been well validated. Methods The feces of the 44 subjects (AMI: 19; control: 25) were collected for fecal genomic DNAs extraction. The variable region V3–V4 of the 16S rRNA gene was sequencing by the platform of Illumina Miseq. The abundances of metabolites were analyzed by the Kyoto Encyclopedia of Genes and Genomes (KEGG) metabolic pathways. Results The abundance of bacteria was more enriched in the AMI group both in the observed operational taxonomic units (OTUs) and faith phylogenetic diversity (PD) ( p -value=0.01 and <0.001 with 95% CI, individually). Selenomonadales was less enriched in the AMI group at the Family, Genus, and Species levels [all linear discriminant analysis (LDA) scores >2]. The seleno-compound was more abundant in the AMI group at the Family, Genus, and Species levels (all LDA scores >2). Conclusions This is the first study to demonstrate Selenomonadales and seleno-compound to be associated with the occurrence of AMI. Our findings provide an opportunity for a novel prevention and treatment of AMI.
