Phylogenetic tree of bacterial species associated with ischemic heart disease (IHD). This phylogenetic tree summarizes the numerous reported gut bacterial species associated with IHD. Background colors in the inner ring indicate all species that belong to the same phylum. The outer rings indicate the enrichment status of each listed bacterial species in IHD cases compared with healthy microbiota. Orange color denotes bacterial species increased in IHD cases, whereas green color denotes bacterial species decreased in IHD cases. This phylogenetic tree was created with iTOL (v6, https://itol.embl.de/).
