Benefits of advanced MRI for patients with heart stiffening disease

Now for the first time they have used the technology to evaluate the success of chemotherapy treatment, by assessing cardiac amyloid regression or progression.

For the study 176 patients with light-chain cardiac amyloidosis had Cardiovascular Magnetic Resonance with Extracellular Volume Mapping. CMR scans with ECV mapping were done at diagnosis, and then at six, 12 and 24 months after starting chemotherapy.

The advanced MRI technique allowed researchers to accurately measure the amount of amyloid protein in hearts, and, for the first-time ever, to measure the changes in response to chemotherapy on repeat scans. By measuring the changes they could detect which patients would have a better or worse prognosis.

Further, combining the results with blood tests for the disease, it was found almost 40% of patients had a substantial improvement (reduction) in amyloid deposition, something that was not thought to be possible before – showing how effective chemotherapy can be.
