Using UK Biobank data from 12,828 people with diabetes, researchers found each standard-unit rise in accelerated biological age was tied to a 40% higher heart failure risk.
Published in Cardiovascular Diabetology, the study tracked participants for an average 13.1 years and recorded 3,794 cardiovascular cases, including coronary artery disease, atrial fibrillation, stroke and valve disease.
The findings do not prove causation, but suggest blood markers could help flag faster internal aging; sleep, exercise, diet and glucose, cholesterol and blood pressure control may slow it.
As home biological age tests proliferate, why do experts warn against using them for medical decisions?
If AI can now predict your internal age from a photo, how will this change preventative medicine?
