Mechanical circulatory support is now widely accepted as a viable long-term treatment option for patients with end-stage heart failure (HF). As the range of indications for the implantation of ventricular assist devices grows, so does the number of patients living in the community with durable support. Because of their underlying disease and comorbidities, in addition to the presence of mechanical support, these patients are at a high risk for medical urgencies and emergencies (Table 1). Thus, it is the responsibility of clinicians to understand the basics of their emergency care. This consensus document represents a collaborative effort by the Heart Failure Society of America, the Society for Academic Emergency Medicine, and the International Society for Heart and Lung Transplantation (ISHLT) to educate practicing clinicians about the emergency management of patients with ventricular assist devices. The target audience includes HF specialists and emergency medicine physicians, as well as general cardiologists and community-based providers.

机械循环支持现已被广泛接受为终末期心力衰竭（HF）患者的可行的长期治疗选择。随着植入心室辅助设备的适应症范围的扩大，在社区中获得持久支持的患者人数也在增加。由于存在潜在的疾病和合并症，除了机械支持外，这些患者的医疗急症和紧急情况的风险也很高（表1）。因此，临床医生有责任了解他们的急诊基础知识。这份共识性文件代表了美国心力衰竭学会，学术急诊医学学会，以及国际心脏和肺移植协会（ISHLT），向执业的临床医生教育有关心室辅助设备患者的紧急处理的知识。目标受众包括心衰专家和急诊医学医生，以及普通心脏病专家和社区服务提供者。
