Kind: research · Impact: medium

## In brief

- Researchers prevented severe heart failure in a mouse model of heart attack by blocking a protein linked to excess scar tissue.
- Excess scar tissue in the heart contributes largely to most heart failure cases, and currently has no treatments.
- The findings come from a mouse model; the source reports no human trial results.

## Why it matters

It points to a possible new therapeutic target for heart failure, a condition that currently lacks treatments aimed at excess cardiac scarring, though the evidence so far is from mice.
