| Outline of Final Research Achievements |
To investigate whether gut microbiota in patients with heart failure (HF) is altered, we compared the gut microbiota of HF patients with that of healthy volunteers. Analysis of the bacterial 16S ribosomal RNA gene provided evidence that the number of operational taxonomic units (OTUs) was not different. However, both unweighted and weighted UniFrac analyses showed a significant difference in gut microbiota samples from HF patients and healthy controls. Furthermore, it also showed a significant difference in gut microbiota samples form younger HF patients and older HF patients. These results suggest that gut microbiota is altered in HF patients, and is also influenced by aging, supporting the concept “Heart-Gut axis” that hemodynamic change in HF may induce dysbiosis, and that it may be involved in the progression of HF.
