摘要

Cardiac amyloidosis (CA), commonly resulting from extracellular protein fibril deposition throughout the body's organ systems, is an important cause of heart failure. In recent years, the contemporary estimates reporting on CA have shown a significant increase in the prevalence rate (18‐55 per 100 000 person‐years). The two major forms of CA accounting for approximately 95% of CA are the transthyretin amyloidosis (ATTR) and immunoglobulin light‐chain (AL) types. Cardiac ATTR may account for up to 15% of heart failure cases in the elderly. CA occurs secondary to the deposition of insoluble protein fibrils in cardiac tissue leading to progressive myocardial dysfunction, heart failure, and arrhythmias. Previous studies have demonstrated not only heart failure but also atrial and/or ventricular tachyarrhythmias, and bradycardias among AL and ATTR cardiomyopathies. These arrhythmias in patients with CA are often very symptomatic and poorly tolerated.
