How heart muscle filaments control pumping strength
Dual filament control of myocardial power and hemodynamics
This project looks at whether changes in heart muscle proteins help the heart pump stronger, which could benefit people with heart failure.

What this research studies
Scientists are examining a heart protein called cMyBP-C and other muscle filaments to see how they affect the heart's power when pumping against pressure. They will use biochemical and biophysical lab tests, genetically modified models, and measurements from failing human heart tissue to see how filament behavior changes. Those results will be combined with detailed computer models that connect changes at the muscle fiber level to overall blood flow and heart function. The team aims to identify molecular steps that could be targeted by small-molecule drugs to help hearts that are failing.
Who could benefit from this research
Good fit: People with heart failure or those undergoing heart surgery or transplant (who could donate tissue samples) would be most relevant to this work.
Not a fit: People without heart muscle disease or whose symptoms come from non-cardiac causes are unlikely to benefit directly from this research.
Why it matters
Potential benefit: Could point to new drug targets that help failing hearts pump more effectively.
How similar studies have performed: Prior laboratory and modeling studies by this team have produced promising mechanistic findings, but applying these insights to patient treatments remains early-stage.
