Effect of β-Blockers on the Left Ventricular Strain in Patients With Wild-Type Transthyretin Amyloid Cardiomyopathy Treated With Tafamidis.

ABSTRACT:

Background

Although tafamidis is used in patients with wild-type transthyretin cardiac amyloidosis (ATTRwt-CM), the effects of β-blockers, one of the conventional heart failure medications, are unclear. Therefore, this study aimed to investigate the effect of β-blockers on left ventricular function using speckle-tracking echocardiography after 1 year of treatment in patients with ATTRwt-CM.

Methods and results

We included 46 patients (median age, 78 years) with ATTRwt-CM confirmed via biopsy. We analyzed laboratory and echocardiographic data, including global longitudinal strain (GLS) to determine left ventricular strain, using 2D speckle-tracking echocardiography and compared the changes in these parameters before and 1 year after treatment with tafamidis between 24 patient
