Good news, for once, and it doesn’t involve some grim, joyless lecture from the public health puritans telling you to subsist entirely on steamed kale and misery.
Scientists at King’s College London have discovered that a compound called urolithin A—which your own body manufactures after you eat pomegranates, walnuts, and berries—can improve heart function by a staggering 80 per cent.
Specifically, it targets the exact kind of heart failure that has previously baffled the medical establishment: Heart Failure with Preserved Ejection Fraction (HFpEF). This is the particularly nasty variant where your heart can still pump blood perfectly well, but becomes as stiff and unyielding as a trade union shop steward, refusing to relax between beats. It accounts for about half of all heart failure cases, leaving millions of people permanently breathless, exhausted, and utterly miserable. Up until now, the NHS could do very little for it beyond telling you to lose weight and stop eating cake.
But this new research, led by Dr Joseph Burgoyne, reveals that urolithin A activates a clever little protein called PKGlα, effectively forcing the heart muscle to relax, reducing internal scarring, and stopping the heart from bloating to a dangerous size.
Now, usually when you read these breathlessly optimistic science stories, the catch is that the drug has only been tested on three pessimistic lab mice and won’t be ready for humans until the turn of the next century. Not so here. The boffins didn’t just see an 80 per cent improvement in animal models; they also tested it on engineered human heart tissue grown from stem cells, and it worked there, too. Better yet, urolithin A has already been through human safety trials and passed with flying colours.
So, if you or someone you love is suffering from a stiff heart, there is genuine, solid hope on the horizon. In the meantime, you might want to consider adding a few more walnuts and pomegranates to your shopping trolley. It certainly beats the usual medical advice of absolute despair.
