Heart scans aim to solve amyloidosis treatment mystery
NCT ID NCT07112066
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at why about one-third of people with a heart condition called cardiac amyloidosis continue to get worse even with medication. Researchers will use special heart scans (ultrasound, MRI, and PET) at the start and after one year to see what is happening inside the heart muscle. The goal is to better understand the disease, not to test a new treatment. 50 adults starting a standard drug called tafamidis will take part.
