Summary

This study looks for early signs of a heart condition called cardiac amyloidosis in people who have had carpal tunnel surgery on both hands. Researchers will use a special heart scan to check for abnormal protein buildup. The goal is to find the disease earlier so treatment can start sooner. About 139 people aged 55 and older who had surgery between 2010 and 2015 will take part.
