[Brief] Study Finds: Hearts from Older Donors Become "Younger" After Transplant into Younger Recipients

[Key Facts] A follow-up study of heart transplant recipients found that hearts from older donors show a clear drop in “biological age” markers — both epigenetic and metabolic — after being transplanted into younger recipients.

By analyzing myocardial tissue samples at multiple time points before and after transplantation, the research team identified a panel of age-related molecular markers and found that the younger the recipient, the more pronounced the “rejuvenation” trend. The result challenges the long-standing conservative matching approach that centered on donor age.

The researchers note that this could potentially expand the donor pool for heart transplantation and ease global organ shortage pressure, though longer-term data are still needed to confirm the impact on distant outcomes.
