A carpal tunnel clue to a silent heart threat?

This study investigates whether people who had carpal tunnel surgery might have a higher chance of having ATTR amyloidosis, a condition where abnormal proteins build up in tissues, potentially affecting the heart. Researchers will biopsy tissue from about 180 patients who had carpal tunnel surgery to check for these proteins. Those with a positive biopsy will be monitored for 10 years with heart imaging to see if they develop cardiac amyloidosis, aiming to understand how often this occurs and how it progresses.
