What this research studies

Researchers at Massachusetts General Hospital will study a protein called FAM3D that was found at higher levels in patients who had better heart healing after a heart attack. They will combine analysis of patient blood samples with lab studies on cardiac fibroblast cells and tests in animal models to see how FAM3D affects inflammation and fibrosis. The team will examine whether increasing FAM3D activity can limit fibroblast activation and reduce scar tissue formation in the heart. Findings are intended to explain how exercise-related benefits may work and to guide development of new therapies for heart failure.

Who could benefit from this research

Good fit: Adults with heart failure or a history of heart attack would be the most relevant group for this research.

Not a fit: People without heart disease or whose heart failure is due to causes unrelated to fibrosis may not benefit directly from these findings.

Why it matters

Potential benefit: If successful, this work could point to new ways to reduce heart scarring and improve heart function for people with heart failure.

How similar studies have performed: Early patient-sample observations and animal experiments suggest FAM3D can protect the heart and limit damage, but direct human treatments based on this approach are still novel.
