Myocardial Depression in Sepsis: Beneficial Adaptation or Sequelae that Requires Treatment?
Myocardial depression is a common yet reversible phenomenon that occurs in patients in septic shock. Initially, it was unclear whether this provided an adaptive survival benefit, as early studies showed decreased mortality in septic patients with myocardial depression. However, subsequent larger studies have debunked this myth. Given that no benefit exists, cardiac dysfunction in septic patients may be monitored via echocardiography and may be treated with inotropic agents. Beta-blockers provide a novel avenue of treatment as they aid in reducing adrenergic overstimulation and cytokine production, which may drive the pathogenesis of septic shock. This review chronicles how the understanding of myocardial depression in sepsis has evolved and how it should be clinically managed.
