Effects of Tafamidis on Left Ventricular Strain in Patients With Wild-Type Transthyretin Cardiac Amyloidosis With and Without Diabetes Mellitus

Background

Tafamidis is used in patients with wild-type transthyretin cardiac amyloidosis (ATTRwt-CA), but the effect of diabetes mellitus (DM) on the efficacy of tafamidis is unknown. Methods and results: We included 57 patients (median age, 77 years) with ATTRwt-CA to compare global longitudinal strain (GLS) before and 1 year after treatment with tafamidis in patients with and without DM (Non-DM, 43 patients; DM, 14 patients). GLS was only ameliorated in patients without DM.
