Diet and the gut microbiota profiles in individuals at risk of chronic heart failure - A review on the Asian population.

BACKGROUND AND

OBJECTIVES

Chronic Heart Failure (CHF) is one of the leading cardiovascular diseases (CVDs), particularly in the Asian population. Individuals with specific health risks, such as obesity, type 2 diabetes, hypertension, dyslipidemia, and coronary artery disease (CAD), are more susceptible to developing CHF. Current evidence is limited to understanding the link between gut microbiota dysbiosis and CHF. Therefore, this review aims to explore the potential connection between dietary patterns, gut microbiota, and its metabolites in individuals at risk of CHF in the Asian population.

METHODS AND STUDY

DESIGN

A literature review of cross-sectional studies was conducted using primary keywords such as "Asian", "obesity", "type 2 diabetes", "hypertension", "dyslipidemia", "coronary artery disease", and "chronic heart failure". There was no restriction on sample size.

RESULTS

Several gut microbiotas were found to correlate with CHF risk factors. There were increased levels of Prevotella, Klebsiella, Romboutsia, Catenibacterium, Clostridium, Holdemanella, Ruminococcus, Coprococcus, Parabacteroides, Bacteroides, Lachnoclostridium, Streptococcus, and Megamonas, while decreased levels of Oscillibacter, Bifidobacterium, Lactobacillus, Akkermansia, Roseburia, Faecalibacterium, Pseudobutyrivibrio, and Eubacterium were reported. These microbiota shifts were linked to increased TMAO production and impaired short-chain fatty acids (SCFAs) production. Dietary intake and microbial metabolites were also identified as contributors to the gut microbiota associated with CHF.

CONCLUSIONS

A potential link exists between the gut microbiota profile and CHF risk factors, possibly mediated by microbial metabolites. Dietary patterns may influence CHF-associated gut microbiota and me-tabolites. Future research is needed to investigate how dietary modifications can modulate gut microbiota and its metabolites in CHF patients.
