Septic Shock and the Heart

AbstractPurpose of ReviewThe aim of this review is to analyze the cardiovascular pathophysiology of septic shock. Using visual representations of a left ventricular cycle in the pressure/volume plane, we describe hemodynamic derangement occurring in septic shock and subsequent changes at each step of treatment allowing a rapid understanding of complex alterations.Recent FindingsAcute circulatory failure during sepsis has to be counterbalanced rapidly and appropriately. The most recent guidelines rely on volume expansion, vasoactive, and inotropic support but underlining patients ’ pathophysiology is often undetermined.SummaryDiagnosis of the hemodynamic substrate needs to be carried out thoroughly, using echocardiography, now commonplace for the intensivist. A pathophysiological approach as we describe might help to understand complicated patterns allowing updates during resuscitation steps.Finally, in our beliefs, clinicians should address septic shock resuscitation using a tailored approach and specific protocols, but their applicability needs to be investigated.
