摘要

Autoantibodies (AAbs) to beta-adrenergic receptors (beta-AR) are common in certain subsets of heart failure, where they have the potential to cause adverse myocardial biological effects.beta_1-AR AAbs are especially common in peri-partum and Chagas cardiomyopathies, but they are also relatively prevalent (>25%) in dilated cardiomyopathies of both idiopathic and ischemic origins. The presence of beta_1-AR AAbs is also associated with ventricular arrhythmias and an increased prevalence of sudden cardiac death.15 As a functional validation of their putative pathophysiologic role, in animal models anti-beta_1-AR antibodies have been shown to induce cardiomyopathies.
