  • Description: Abstract Aims β1-adrenergic receptor autoantibodies (β1-AAs) and β2-adrenergic receptor autoantibodies (β2-AAs) are present in patients with heart failure (HF); however, their interrelationship with cardiac structure and function remains unknown. This study explored the effects of the imbalance between β1-AAs and β2-AAs on cardiac structure and its underlying mechanisms in HF. Methods and results Patients with left systolic HF who suffered from coronary heart disease (65.9%) or dilated cardiomyopathy (34.1%) were divided into New York Heart Association Classes I-II (n = 51) and Classes III-IV (n = 37) and compared with healthy volunteers as controls (n = 41). Total immunoglobulin G from HF patient serum comprising β1-AAs and/or β2-AAs were determined and purified for in vitro studies from neonatal rat cardiomyocytes (NRCMs). In addition, HF was induced by doxorubicin in mice. We observed that the increased ratio of β1-AAs/β2-AAs was associated with worsening HF in patients. Moreover, β2-AAs from patients with HF suppressed the hyper-shrinking and apoptosis of NRCMS induced by β1-AAs from some patients. Finally, β2-AAs alleviated both myocardial damage and β1-AAs production induced by doxorubicin in mice. Conclusion β2-AAs were capable of antagonizing the effects imposed by β1-AAs both in vitro and in vivo. The imbalance of β1-AAs and β2-AAs in patients with HF is a mechanism underlying HF progression, and the increasing ratio of β1-AAs/β2-AAs should be considered a clinical assessment factor for the deterioration of cardiac function in patients with HF.
