How a diabetes drug helps heal a damaged heart
Dapagliflozin attenuates post-infarction fibrosis via cardiomyocyte protection and fibroblast inhibition.

A medicine called dapagliflozin, used for diabetes, was tested in rats with heart attacks. It helped their hearts work better and live longer by calming down scar-making cells and protecting heart muscle cells from stress.
Surprising Findings
Activating the Wnt/β-catenin pathway with CHIR99021 completely erased dapagliflozin’s anti-fibrotic effects.
Most drugs work by blocking one pathway, but here, turning on a single pathway (Wnt/β-catenin) undid all the benefits—proving it’s not just correlated, but essential to the mechanism.
Practical Takeaways
If you or a loved one has had a heart attack, ask your doctor if dapagliflozin (Farxiga) is an option—especially if you have diabetes or heart failure.

In rats that had a heart attack, a drug called dapagliflozin helped them live longer and made their hearts pump better, according to ultrasound scans.
When heart cells that cause scarring are hurt, a drug called dapagliflozin seems to help them produce less scar tissue and act less like scar-forming cells.
When heart cells are damaged by a stress chemical, a diabetes drug called dapagliflozin helps calm the damage by lowering harmful chemicals and bringing back a protective enzyme.
After a heart attack in rats, a diabetes drug called dapagliflozin seems to calm down the heart’s inflammation by reducing harmful immune cells and chemicals, while boosting a helpful one that soothes the damage.
A drug called dapagliflozin helps reduce scarring in heart cells, but when scientists turn on a specific cellular pathway with another chemical, that helpful effect disappears.
