Popis: Patients with cardiogenic shock may require stabilization with temporary mechanical circulatory support (tMCS) to assess candidacy for definitive therapy, including heart transplantation (HTx) or durable MCS, and/or maintain stability while on the HTx waiting list. We describe the clinical characteristics and outcomes of patients with cardiogenic shock who underwent intra-aortic balloon pump (IABP) vs. Impella [Abiomed, Danvers, MA, USA] placement at a high-volume advanced heart failure center. We assessed patients ≥ 18 years who received IABP or Impella support for cardiogenic shock from 1 January 2020 to 31 December 2021. Ninety patients were included, 59 (65.6%) with IABP and 31 (34.4%) with Impella. Impella was used more frequently in less stable patients, as evidenced by higher inotrope scores, greater ventilator support, and worse renal function. While patients on Impella support had higher in-hospital mortality, despite the worse cardiogenic shock in patients for whom clinicians chose Impella support, over 75% were successfully stabilized to recovery or transplantation. Clinicians elect Impella support over IABP for less stable patients, though a high proportion are successfully stabilized. These findings demonstrate the heterogeneity of the cardiogenic shock patient population and may inform future trials to assess the role of different tMCS devices.
