The gut microbiota influences cardiovascular health by producing compounds like TMAO and SCFAs. Analyzing gut bacteria and biomarkers aids in preventing cardiovascular diseases through personalized lifestyle interventions.
Area of Science:
- Microbiology
- Cardiovascular Medicine
- Immunology
Background:
- Cardiovascular diseases (CVD) remain a leading cause of global mortality.
- Emerging research highlights the gut microbiota's significant role in cardiovascular health, extending beyond traditional risk factors.
Purpose of the Study:
- To review the gut microbiota's role in linking diet, immunity, and CVD.
- To explore molecular mechanisms, novel biomarkers, and clinical implications.
- To emphasize the potential of gut microbiota analysis for preventive cardiology.
Main Methods:
- Literature review focusing on gut microbiota, diet, immunity, and CVD.
- Analysis of molecular mechanisms involving bioactive compounds (e.g., TMAO, SCFAs).
- Examination of multi-omics technologies for biomarker discovery.
Main Results:
- Gut microbiota metabolites (TMAO, SCFAs) impact inflammation, endothelial function, and lipid metabolism.
- Increased intestinal permeability and bacterial endotoxins contribute to atherosclerosis.
- Identified biomarkers include plasma TMAO, Firmicutes/Bacteroidetes ratio, and SCFA patterns.
Conclusions:
- Gut microbiota analysis and specific biomarkers support personalized dietary strategies and risk assessment.
- Monitoring gut microbiota facilitates a preventive medicine approach through lifestyle interventions.
- This strategy holds promise for improving public health and healthcare sustainability.
