Cardiac resynchronization therapy (CRT) is highly effective in dilated cardiomyopathy (DCM) patients with impaired left ventricular ejection fraction (LVEF) and left bundle block branch. In cardiac amyloidosis (CA) patients, left ventricular dysfunction and conduction defects are common, but the potential of CRT to improve cardiac remodelling and survival in this particular setting remains undefined. We investigated cardiovascular outcomes in CA patients after CRT implantation in terms of CRT echocardiographic response and major cardiovascular events (MACEs).

心脏淀粉样变性心脏再同步化治疗后的心血管结局

心脏再同步化治疗 (CRT) 对左心室射血分数 (LVEF) 和左束传导阻滞支受损的扩张型心肌病 (DCM) 患者非常有效。在心脏淀粉样变性 (CA) 患者中，左心室功能障碍和传导缺陷很常见，但 CRT 在这种特殊情况下改善心脏重塑和生存的潜力仍未确定。我们根据 CRT 超声心动图反应和主要心血管事件 (MACE) 调查了 CA 患者在 CRT 植入后的心血管结局。
