High-resolution heart MRI and AI to understand poor heart relaxation
Integrated super-resolution CMR-deep learning to deconvolute passive and active causes of impaired relaxation
This project uses high-resolution cardiac MRI combined with artificial intelligence to tell apart stiffness and active relaxation problems in people whose hearts don't relax well, such as those with HFpEF or hypertrophic cardiomyopathy.

What this research studies
This work will combine super-resolution cardiac MRI (to get very detailed images of heart structure and motion) with deep learning models that analyze how the heart muscle relaxes. The team will use imaging data and computational models to separate passive stiffness (from fibrosis or thickening) from active relaxation problems at the muscle fiber level. They will validate the approach with complementary lab and imaging data so the measurements reflect real biological causes. If successful, the method would allow doctors to see which mechanism is driving a patient’s impaired relaxation without invasive tests.
Who could benefit from this research
Good fit: Adults with diagnoses or symptoms of left ventricular diastolic dysfunction such as heart failure with preserved ejection fraction, hypertrophic cardiomyopathy, or diabetic cardiomyopathy would be the ideal candidates.
Not a fit: People whose problems are mainly systolic heart failure, isolated valve disease, or non-cardiac causes of symptoms may not benefit from this specific imaging approach.
Why it matters
Potential benefit: If successful, this could help doctors pick treatments that target the true cause of a patient’s poor heart relaxation, improving care and avoiding ineffective therapies.
How similar studies have performed: Researchers have used MRI and AI to improve heart imaging before, but using these tools to separate passive versus active causes of impaired relaxation in living patients is largely new and not yet proven.
