Abstract

BACKGROUND: Cardiogenic shock (CS) is the leading cause of death in patients with myocardial infarction with a mortality rate greater than 50%. Recently, the CS 4 Proteins (CS4P) and CLIP scores have been developed to predict survival in CS patients. However, their impact in acute CS and additional short-term left ventricular (LV) circulatory support as prognostic markers is currently not known.

METHODS AND RESULTS: CS was induced in a porcine model by injecting microsphere particles into the left main coronary artery. Mechanical circulatory support was performed by additional percutaneous LV unloading using an Impella microaxial flow-pump for 30 minutes. Serum samples were collected at baseline, following the onset of CS, and additional LV unloading. Serum levels of biomarkers of the CS4P (beta-2-microglobulin, ALDOB, L-FABP, SerpinG1) and the CLIP scores (Cystatin C, Lactate, Interleukin-6, NT-proBNP) were neither different at any time point investigated nor did they correlate with cardiac output.

CONCLUSION: The CS4P and CLIP scores do not reflect immediate whole-body dysregulation in acute CS and have not been able to predict the potential reversal following additional short-term mechanical support by LV unloading in our experimental model. The impact of both scores as prognostic markers after the immediate onset of CS and following additional short-term LV unloading to identify patients at greatest risk remains to be determined.
