Heart Failure and Gut Microbiota: What Is Cause and Effect?

Area of Science:

• Microbiology
• Cardiology
• Physiology

Background:

• Gut microbiota plays a crucial role in host homeostasis.
• Alterations in gut microbiota are linked to metabolic and inflammatory destabilization, contributing to cardiometabolic diseases.
• Intestinal dysfunction in heart failure (HF) can lead to dysbiosis, exacerbating the condition via the gut-heart axis.

Purpose of the Study:

• To review current research on the connection between gut microbiota and heart failure.
• To explore the mechanisms underlying the gut-heart axis in HF.
• To discuss future research directions and therapeutic potential.

Main Methods:

• Literature review of existing studies on gut microbiota and HF.
• Analysis of the gut-heart axis in the context of HF pathophysiology.
• Synthesis of findings to identify knowledge gaps and future avenues.

Main Results:

• Gut microbiota dysbiosis is increasingly recognized as a factor in HF development and progression.
• The gut-heart axis provides a pathway through which intestinal changes influence cardiac function.
• Therapeutic strategies targeting gut microbiota balance may offer novel approaches to HF management.

Conclusions:

• Understanding the gut microbiota-HF relationship is vital for elucidating disease mechanisms.
• Modulating the gut microbiota presents a promising therapeutic avenue for improving HF outcomes.
• Further research is needed to fully harness the potential of targeting the gut microbiome in HF treatment.
