Clinical Utility of Longitudinal Measurement of Hemodynamic Incoherence and Endothelial
Purpose: To assess the prognostic role of Handheld Vital Microscopy (HVM) and evaluate levels of endothelial glycocalyx (eGC) breakdown in patients demonstrating Hemodynamic Incoherence (HI), to elucidate a mechanistic link between the eGC and HI in order to inform prognostic enrichment of future resuscitation trials. We will serially evaluate microhemodynamics (MiH) and macro hemodynamics (maH) and the perfused boundary region (PBR, an visual proxy for eGC thickness) using HVM, and a validated circulating biomarker of eGC integrity.
