Abstract:
Objective: To analyze the changes on gut microbiota and metabolic products in patients with chronic heart failure. Methods: By searching the Pubmed, EMBASE, Cochrane Library, and CNKI, Wanfang, and CMB databases from the day of built up to December 2019, we screened related literature exploring the intestinal flora of chronic heart failure patients, and systematic review was performed to study changes in intestinal flora composition, function, and metabolites among chronic heart failure patients. Results: A total of 10 articles were included to study the gut microbiota of patients with chronic heart failure in this analysis. The systematic review showed significant changes in β-diversity in patients with heart failure. The abundance of faecalibacterium, blautia, bacteroides, prevotella and anaerostipes was decreased, while the abundance of streptococcus, escherichia/shigella, veillonella, and enterobacte was increased. The increased microbial gene function in patients with heart failure included tryptophan metabolism, lipid metabolism, LPS synthesis,and so on, especially, bacterial genes related to trimethylamine oxide production increased significantly, while genes related to key enzymes producing the beneficial metabolite butyrate decreased significantly, and harmful metabolite trimethylamine oxide levels increased in chronic heart failure patients. Conclusion: There are significant changes in the structure, function and metabolites of intestinal flora in patients with chronic heart failure.
