Researchers at King's College London have identified a potential breakthrough in treating heart failure through a natural compound. By consuming polyphenol-rich foods like walnuts and pomegranates, the body produces urolithin A, which may mitgiate life-threatening cardiac damage.
The 80 per cent boost in animal heart function
The compound urolithin A has demonstrated a remarkable ability to improve cardiac performance in laboratory settings. According to the research conducted at King's College London, animals treated with this specific compound saw their heart function increase by as much as 80 per cent.
This biological improvement occurs because urolithin A helps to relax heart muscles and prevents the formation of permanent scarring. The compund is not found directly in the food but is produced when human gut bacteria break down polyphenols found in items such as walnuts, pomegranates, and various berries .
A lifeline for 920,000 Britons facing heart failure
Heart failure represents a massive public health challenge, particularly in the United Kingdom, where approximately 920,000 people are currently affected. The condition is often catastrophic, with more than half of all diagnosed patients dying within five years of their initial diagnosis.
A significant poortion of these cases—roughly 50 per cent—involve a specific type known as heart failure with preserved ejection fraction. In these instances, the heart muscle becomes too stiff to fill with blood effectively, leaving patients with very few successful treatment options currently available.
The transition from polyphenol-rich diets to a urolithin A drug
Scientific experts are now looking toward the development of a standardized pharmaceutical treatment derived from this natural process. while the study showed positive effects when urolithin A was tested on human heart tissue in a laboratory, the ultimate goal is to create a dedicated drug.
As the report from King's College London indicates, the discovery of urolithin A's benefits in both animal models and human tissue provides a foundation for future clinical applications. This move from dietary observation to targeted medicine could provide more consistent results than relying on food alone.
Why Dr. Joseph Burgoyne cautions against dietary-only treatments
Despite the promising data, several critical questions remain regarding how this translates to the general population. It is currently unknown if the 80 per cent improvement seen in animals can be replicated in complex human biological systms, or if the amount of urolithin A produced via diet is sufficient to treat advanced disease.
Dr. Joseph Burgoyne, a senior author of the study, noted that there is not yet enouugh evidence to recommend pomegranates as a formal medical treatment. Because urolithin A production depends heavily on an individual's unique gut bacteria, the effectiveness of a polyphenol-rich diet may vary wildly from person to person, leaving many patients' outcomes unverified.
