How scarring changes the heart's stretchiness and affects heart muscle cells
Cardiomyopathy-induced changes in myocardial viscoelasticity and its effects on cell phenotype
This project looks at whether scarring in people with hypertrophic or dilated cardiomyopathy makes the heart stiffer and changes how heart muscle cells work.

What this research studies
Researchers will measure how the mechanical properties of heart tissue change in hypertrophic and dilated cardiomyopathy compared with healthy hearts. They will recreate those healthy and diseased mechanical environments in the lab using engineered materials that mimic tissue viscoelasticity. Heart muscle cells will be placed on these materials to see how stiffness and viscosity alter cell behavior and function. Findings will link changes in the extracellular matrix to shifts in cell phenotype that could drive disease progression.
Who could benefit from this research
Good fit: People with hypertrophic cardiomyopathy or dilated cardiomyopathy, or those willing to donate cardiac tissue or clinical data, would be the most relevant participants.
Not a fit: People without cardiomyopathy or those seeking immediate therapies are unlikely to receive direct benefit from this basic laboratory-focused project.
Why it matters
Potential benefit: If successful, this work could reveal new ways to protect heart muscle or slow cardiomyopathy by targeting the tissue's mechanical properties.
How similar studies have performed: Related research shows mechanical environments can change muscle cell behavior in other tissues, but applying these methods specifically to myocardial viscoelasticity and cardiomyocytes is relatively new.
