Diet-Induced Microbiome's Impact on Heart Failure: A Double-Edged Sword

Area of Science:

• Microbiology
• Cardiology
• Human Microbiome Research

Background:

• Heart failure (HF) presents a substantial global health and economic burden.
• Hypertension, obesity, and diabetes are key risk factors for HF development.
• Chronic inflammation and gut dysbiosis are implicated in HF pathophysiology, influencing cardiovascular disease risk via the gut microbiome (GM).

Purpose of the Study:

• To elucidate the intricate relationship between heart failure and the human microbiome.
• To explore novel therapeutic avenues for HF, particularly for HFpEF patients.
• To investigate the impact of lifestyle interventions, like diet, on the GM and cardiac health.

Main Methods:

• Literature review and synthesis of current research on HF, chronic inflammation, and the gut microbiome.
• Analysis of studies investigating the role of gut dysbiosis in cardiovascular disease.
• Examination of evidence linking lifestyle modifications to cardiometabolic health and the microbiome.

Main Results:

• The gut microbiome significantly influences HF pathophysiology through its association with chronic inflammation.
• Gut dysbiosis is a modifiable factor potentially impacting cardiovascular disease risk.
• Lifestyle interventions, including dietary changes, show promise in managing cardiometabolic diseases by affecting the GM.

Conclusions:

• The gut microbiome represents a promising target for novel heart failure therapies.
• Further research is needed to fully understand the therapeutic potential of modulating the GM for HF management.
• Targeting the gut microbiome could offer new strategies to reduce mortality and improve quality of life in HF patients.
