Background: The intra-aortic balloon pump (IABP) is a commonly used temporary mechanical circulatory support device in cardiogenic shock (CS). A substantial proportion of patients receive IABP at referring hospitals prior to transfer. The aim of this study was to compare clinical characteristics, treatment strategies, and outcomes between transferred and nontransferred IABP-treated patients with all-cause CS, acute myocardial infarction-related CS (AMI-CS), and heart failure-related CS (HF-CS). Methods: Intra-aortic balloon pump-treated CS patients from the multicenter Cardiogenic Shock Working Group registry (2020-2024) were analyzed. Adjusted logistic regression models were used to assess associations between transfer status and in-hospital mortality, native heart survival, heart replacement therapies, and in-hospital complications. Results: = .006). Conclusions: Transfer status was independently associated with higher in-hospital mortality and complications. These findings emphasize the importance of structured referral pathways and heightened awareness at hub centers for this potentially high-risk IABP-treated CS cohort.
