Researchers are exploring how pomegranates, an ancient Iranian fruit with antioxidant properties, might treat a specific type of heart failure where the heart struggles to relax and fill properly despite pumping blood normally. In studies on animals and human heart tissue engineered from stem cells, compounds derived from pomegranates showed significant improvement in heart function by activating a protein that promotes relaxation of heart muscle and reduces scarring and harmful enlargement. While promising, further clinical trials are needed before confirming its effectiveness for treating this condition.

Story summary
A growing health concern in America is heart failure with preserved ejection fraction (HFpEF), where the heart still pumps blood effectively but struggles to relax properly. This condition affects millions and is expected to nearly double from 6.7 million people in 2024 to 11.4 million by 2050. Researchers are exploring new treatments, focusing on a compound called urolithin A, which forms after consuming fruits like pomegranates, walnuts, and berries. Pomegranate is particularly significant as it is an ancient fruit native to Iran known for its antioxidant properties. Studies show that urolithin A can improve heart relaxation in both animals and human engineered heart tissue, potentially offering a breakthrough treatment for HFpEF.

A silent yet deadly epidemic is sweeping the nation, with the number of Americans living with heart failure expected to nearly double from 6.7 million in 2024 to 11.4 million by 2050.

While widely known for its antioxidant properties, one popular fruit could also hold the key to improving a particular type of heart failure millions live with.

millions → know → failure
The postbiotic (what’s left over after gut bacteria digest food) is made after eating foods like walnuts, berries and pomegranates, a famous superfood and the most well-known ancient fruit native to Iran.

Namely, they looked into treating heart failure with preserved ejection fraction, where the heart still pumps blood but struggles to relax and properly fill.
asserted
heart → look → blood
In both animals and engineered human heart tissue, the compound significantly improved relaxation while also reducing scarring and limiting harmful enlargement of the heart.
asserted
compound → engineer → heart
Heart failure with preserved ejection fraction is often difficult to treat due to several factors, including aging, high blood pressure and diabetes, contributing to it.
asserted
failure → preserve → it
Researchers found that urolithin A activates a protein called PKGlα, which promotes relaxation of blood vessels and the heart muscle.
asserted
which → find → vessels
In animal models, a urolithin A treatment improved measures of heart function by as much as 80%.
asserted
treatment → improve → %
The compound also significantly improved heart function in human heart tissue engineered from stem cells, suggesting the effects in animal hearts could translate to humans.
uncertain
effects → improve → humans
While more research is needed to determine the full effects, the results suggest a promising solution from a naturally derived compound that’s already known to have a favorable safety profile in humans.
asserted
that → need → humans
The findings of the research also pave the way for new treatments for heart failure with preserved ejection fraction.

“Despite its growing burden, treatment options remain limited because the disease is complex and varies considerably between patients,” senior study author Dr. Joseph Burgoyne said in a press release.
asserted
Burgoyne → grow → release
And because the heart still pumps blood as it should, traditional heart failure treatments are ineffective, prompting doctors to focus on managing underlying conditions or lifestyle changes, like weight loss, instead.
asserted
treatments → pump → loss
Although there isn’t enough evidence that only eating pomegranates will cure heart failure, Burgoyne suggests that the findings “raise the possibility that dietary approaches that enhance urolithin A production may help alleviate this condition.”
Additional clinical trials in humans will be necessary to test if the approach is effective, while eating a healthy, balanced diet remains one of the best ways to attain a healthy heart.
