Materials and methods: 300 patients were divided into 3 groups: first (CAD) – 149 patients with CAD but without arrhythmias, second (CAD+AF) – 124 patients with CAD and AF paroxysm and control group – 27 patients without CAD and arrhythmias. Plasma AA level was detected by ion exchange liquid column chromatography method. 16-S rRNA sequencing checked gut microbiota composition. Results: The II group patients are characterized by a significant increase in Actinobacter Spp. and a decrease in Blautia Spp., Bacteroides Thetaiotaomicron;a significant increase in glutamate, branched-chain amino acids, Fishers’ ratio, and a decrease in glycine levels (P<0.05). Pathogenic species have such significant correlations: Streptococcus Spp. with tyrosine (r=0.301), phenylalanine (r=0.340), aromatic amino acids (r=0.345), Fishers’ ratio (r=0.319); Escherichiacoli with arginine (r=-0.331), serine (r=-0.337), valine (r=-0.332);(P<0.05). Probiotic species have such significant correlations: Bifidobacterium Spp. with glycine (r=0.505), Fishers’ ratio (r=-0.371); Blautia Spp. with ornithine (r=0.329), glycine (r=0.414), alanine (r=0.316); Eubacteriumrectale. with ornithine (r=0.379), glycine (r=0.467), alanine (r=0.384), Fishers’ ratio (r=0.418);(P<0.05).Conclusions: Plasma amino acids and gut microbiota are closely connected. popup.nrat_date 2026-04-22 Close
