Empagliflozin's Microcirculatory Effects in Cardiogenic Shock: an Ancillary Pilot Study of the EMPASHOCK Trial

Despite advancements in treatment, the mortality rate for cardiogenic shock (CS) remains high at around 50%. The EMPULSE-HF trial showed that early introduction of empagliflozin in stabilized patients with acute heart failure led to a composite benefit in mortality, rehospitalization, and quality of life. Growing evidence suggests that cardiogenic shock isn't just a problem of systemic macrocirculation (blood pressure, cardiac output). It also involves significant abnormalities in the systemic microcirculation. In fact, these microcirculatory parameters have proven to be better predictors of patient outcomes than traditional macrocirculatory measures. Given its known vasculo-protective effects on the endothelium, empagliflozin may have a beneficial impact on the microcirculation, potentially explaining its positive effects in cardiogenic shock. This study will explore this hypothesis by analyzing the microcirculation in real-time using the CytoCam-IDF imaging videomicroscope and its MicroTools software. The goal is to gain a deeper understanding of how empagliflozin affects the microcirculation during cardiogenic shock.
