Left ventricular assist devices (LVADs) are implanted to support the circulation of patients with advanced heart failure. Patients approaching death, or their surrogates, may request withdrawal of LVAD support. We sought to study the attitudes and practices of heart failure clinicians regarding withdrawal of LVAD support in patients approaching death.
Using internet-based and secure methods, we surveyed members of the European Society of Cardiology-Heart Failure Association (ESC-HFA), the International Society for Heart and Lung Transplantation (ISHLT), and the Heart Failure Society of America (HFSA) to assess their attitudes and practices regarding LVAD withdrawal for patients approaching death. The results indicated that clinicians have varied attitudes and practices regarding withdrawing LVAD support in these patients. Furthermore, ESC-HFA clinicians (primarily European) and ISHLT and HFSA clinicians (primarily North American) differed in their attitudes and practices regarding withdrawal of LVAD support, particularly its ethical and legal permissibility. For example, more European clinicians than North American clinicians regarded withdrawing LVAD support as a form of euthanasia.
Opinions and level of comfort with LVAD withdrawal vary among clinicians. Clinicians should be aware of suggested approaches or guidelines for managing requests for withdrawal of LVAD therapy.
左心室辅助装置(LVAD)用于支持晚期心力衰竭患者的循环。接近死亡的患者或其代理人可能会要求撤回 LVAD 支持。我们旨在研究心力衰竭临床医生对接近死亡的患者撤回 LVAD 支持的态度和做法。
我们使用基于互联网的安全方法,调查了欧洲心脏病学会-心力衰竭协会(ESC-HFA)、国际心肺移植学会(ISHLT)和美国心力衰竭协会(HFSA)的成员,以评估他们对接近死亡的患者撤回 LVAD 支持的态度和做法。结果表明,临床医生在这些患者中撤回 LVAD 支持的态度和做法存在差异。此外,ESC-HFA 临床医生(主要是欧洲人)和 ISHLT 和 HFSA 临床医生(主要是北美人)在撤回 LVAD 支持的态度和做法上存在差异,尤其是在其伦理和法律许可方面。例如,与北美临床医生相比,更多的欧洲临床医生将撤回 LVAD 支持视为安乐死的一种形式。
临床医生对 LVAD 撤回的意见和舒适度存在差异。临床医生应该了解管理撤回 LVAD 治疗请求的建议方法或指南。
