Early Diagnosis of Amyloidosis and Cardiac Involvement through Carpal Tunnel Surgery and Predictive Factors.

: To determine the prevalence of amyloidosis through the analysis of synovial tissue and transverse carpal ligament (TCL) in patients undergoing surgery for carpal tunnel syndrome (CTS), detect predictive factors for the presence of amyloid, and assess cardiac involvement degree. : A prospective study with longitudinal cohort follow-up at a teaching hospital. Patients undergoing CTS surgery from 1 January 2019 to 31 May 2021 were included.

Trends in diagnosis of cardiac transthyretin amyloidosis: 3-year analysis of scintigraphic studies: Prevalence of myocardial uptake and its predictor factors.

To determine the prevalence of myocardial uptake (MU) and to identify predictors of MU in patients undergoing scintigraphy. Retrospective single-center series of technetium-99 m-labelled 3,3-diphosphono-1,2-propanodicarboxylic acid (99mTc-DPD) scans performed from March 2017 to March 2020. All patients undergoing scintigraphy were included, except those with preexisting amyloidosis.
