Open the original (DOI 10.7759/cureus.14546)- What it measures
- The review explains that transthyretin amyloid can deposit in the flexor tenosynovium and cause carpal tunnel syndrome, and that the same protein can later deposit in the heart.
- What it does not show
- The interval is an approximate figure drawn from other reports and case series, not from a prospective study following patients from carpal tunnel to heart disease.
