Heart failure & cardiomyopathies
Early Diagnosis of ATTR-CM Using Carpal Tunnel Biopsy Examination: EDUCATE: A United Kingdom Prospective Multicenter Study
Authors' conclusion
Transthyretin amyloid (ATTR) is commonly present in the tenosynovium and transverse carpal ligaments of older people with carpal tunnel syndrome, and more than one quarter of whom have ATTR cardiac amyloid infiltration that is readily identifiable using bone scintigraphy.
Study context
- Population
- Unselected patients >50 years undergoing carpal tunnel decompression, UK; no existing amyloidosis diagnosis315 women
- Participants
- 555 patients
- Outcome
- Amyloid on carpal tunnel biopsy and myocardial amyloid (ATTR-CM) on Tc-DPD scintigraphy in biopsy-positive patients
Methodological detailsprospective, multicentre
- Prospective
- Multicentre
