Abstract

Transthyretin cardiac amyloidosis is a progressive disease known to cause heart failure, conduction anomalies, and arrythmias. Due to poor outcomes and mortality from severe cardiomyopathy, prevalence and incident rates are often underreported. As global longevity is increasing and rates of amyloidosis are also increasing, there is a need to improve diagnostic and therapeutic interventions. Previously, symptom management and transplantation were the mainstay of treatment for heart failure symptoms, but studies using RNAi and siRNA technologies have shifted the paradigm of therapeutic strategy in amyloid cardiomyopathy management. Additionally, early detection and clinical monitoring with numerous imaging and non-imaging techniques are being increasingly investigated. Here, we review the epidemiology, pathophysiology, diagnosis, and management of transthyretin amyloid cardiomyopathy.

Keywords: amyloidosis; cardiomyopathy; heart failure; transplantation.
