# Exploring the gut-heart axis: A prospective analysis of microbiota in cardiovascular health

## TL;DR

This study explores how gut bacteria may influence heart health, finding that certain bacterial ratios are linked to higher cardiovascular disease risk.

## Contribution

The study identifies a specific gut microbiota signature associated with increased cardiovascular disease risk over time.

## Key findings

- A higher Firmicutes/Bacteroides ratio correlates with greater incidence of cardiovascular disease.
- Microbial taxa are linked to lipid metabolism and systemic inflammation markers.
- Targeting the gut microbiome may offer a strategy to reduce cardiovascular disease risk.

## Abstract

The relationship between gut microbiota composition and the development of cardiovascular disease, with a potential role of microbial
metabolites in inflammatory and metabolic pathways is of interest. We analyzed gut microbiota and markers of cardiovascular health in a
cohort of 100 participants for three years to search for microbial signatures correlated with increased CVD risk. Our results show
several correlations between specific microbial taxa, lipid metabolism and systemic inflammation, whereby a higher Firmicutes/Bacteroides
ratio is associated with a greater incidence of CVD. These results suggest that intervention targeting the microbiome has the potential
to reduce risk for CVD and point towards a role for gut microbiota in cardiovascular health.
