Arrhythmic stratification of cardiac amyloidosis: state of the art

Cardiac amyloidosis is an infiltrative myocardial disease whose prevalence significantly increased in recent years. Its clinical history is changing due to the advent of novel therapies, and careful risk stratification has become impelling. Arrhythmias, frequently found during the course of the disease, include conduction system disease, atrial fibrillation (AF), and ventricular arrhythmias (VAs). Arrhythmic risk stratification is a key to identify those patients at higher risk to develop advanced atrioventricular blocks, asymptomatic AFs, or major VAs. This carries significant clinical implications concerning the indication and timing of implantable cardiac devices, as well as the initiation of anticoagulation therapy.
