New scan spots hidden heart disease in gene carriers before symptoms start

This study aims to see if a new radioactive dye can detect early signs of a heart condition called amyloidosis in people who carry a TTR gene mutation but have no heart failure symptoms. About 80 adults aged 30-80 will receive an injection of the dye and then have a PET/CT scan to look for amyloid buildup in the heart. The goal is to find disease earlier so treatment can begin sooner.
