The figure shows the correlations between blood biomarkers and gut bacteria that associate with specific OCT/IVUS features at the genus level. Notable bacteria are summarized in Figure 5. AT3 indicates antithrombin III; BNP, B‐type natriuretic peptide; F1+2, prothrombin fragment F1+2; HbA1c, glycosylated hemoglobin; Hct, hematocrit; HDL‐C, high‐density lipoprotein cholesterol; hs‐CRP, high‐sensitivity C‐reactive protein; IGF 1, insulin‐like growth factor 1; IL, interleukin; IVUS, intravascular ultrasound; LDL‐C, low‐density lipoprotein cholesterol; Lp(a), lipoprotein (a); OCT, optical coherence tomography; PAI‐1, plasminogen activator inhibitor‐1; PAV, percent atheroma volume; Plt, platelet; SCFA, short‐chain fatty acid; TAT, thrombin–anti‐thrombin complex; TAV, total atheroma volume; TCFA, thin‐cap fibroatheroma; T‐chol, total cholesterol; TG, triglyceride; TGFβ, transforming growth factor β; TMAO, trimethylamine N‐oxide; TNFα, tumor necrosis factor α; and WBC, white blood cell.
