500 Years Later, Scientists Solve Leonardo Da Vinci’s Human Heart Mystery
Scientists have finally decoded the function of the heart's trabeculae, a delicate muscular network first sketched by Leonardo da Vinci five centuries ago. Using fractal analysis, MRI data and biomechanical simulations on 18,096 UK Biobank participants, the team linked trabecular morphology to cardiac performance and disease risk. Genetic analysis uncovered 16 loci influencing trabeculae development, suggesting a hereditary component. The findings open a new frontier in understanding adult heart mechanics and potential targets for cardiovascular therapy.
