Complications and Outcomes in 39,864 Patients Receiving Standard Care Plus Mechanical Circulatory Support or Standard Care Alone for Infarct-Associated Cardiogenic Shock.

Background: Temporary mechanical circulatory support devices (tMCS) are increasingly being used in patients with infarct-associated cardiogenic shock (AMICS). Evidence on patient selection, complications and long-term outcomes is lacking. We aim to investigate differences in clinical characteristics, complications and outcomes between patients receiving no tMCS or either intra-aortic balloon pump (IABP), veno-arterial extracorporeal membrane oxygenation (V-A ECMO) or Impella for AMICS, with a particular focus on long-term outcomes.
