New Pacemaker Trains Heart to Burn Fat, Not Sugar
18 Jan
Summary
- Scientists retrained hearts to burn fat instead of sugar.
- A new pacemaker was used in a trial with 14 patients.
- Heart failure symptoms were reversed in participants.

A novel pacemaker developed by scientists at the University of Oxford and the British Heart Foundation has demonstrated the ability to reverse heart failure symptoms. This innovative device works by retraining the heart to utilize fat for fuel rather than relying on sugar.
The groundbreaking trial involved 14 patients who received the specialized pacemaker. Early results indicate significant success in altering the heart's metabolic process, leading to a reversal of heart failure symptoms among the participants.
This research marks a significant advancement in cardiac care, offering a new therapeutic strategy for individuals suffering from heart failure. The potential to reprogram cardiac metabolism presents a promising avenue for future treatments.
