First-Line Support by Intra-Aortic Balloon Pump in Non-Ischaemic Cardiogenic Shock in the Era of Modern Ventricular Assist Devices
Objectives: Little is known about circulatory support in cardiogenic shock (CS) from other causes than the acute coronary syndrome or after cardiotomy. We evaluated the effects of first-line intra-aortic balloon pump (IABP) support in this subpopulation of CS patients. Methods: A retrospective study was performed in 27 patients with CS from end-stage cardiomyopathy supported firstly by IABP in the years 2011-2016. Results: At 24 h, lactate decreased from 3.2 (2.1-6.8) to 1.8 (1.2-2.2) mmol/L (p < 0.001). Eighteen patients (67%) defined as IABP responders were successfully bridged to either recovery (n = 7), left ventricular assist device (n = 5), or heart transplantation (n = 6). IABP failed in 9 patients (non-responders, 33%) who either died (n = 7) or needed support by extracorporeal membrane oxygenation (n = 2). At 24 h of IABP support, urinary output was higher (2,660 [1,835-4,440] vs. 1,200 [649-2,385] mL; p = 0.02) and fluid balance more negative (-1,564 [-2,673 to -1,086] vs. -500 [-930 to +240] mL; p < 0.001) in responders than non-responders. Overall survival at 1 year was 63%. Conclusion: In most patients, first-line support by IABP in end-stage cardiomyopathy is associated with improvement in organ perfusion and clinical stabilisation for at least 24 h allowing time for decision making on next therapies.
