Severe sepsis causes myocardial depression, impacting heart function early in most patients. This cardiac dysfunction, linked to inflammatory mediators, typically resolves in survivors within 10 days.

Area of Science:

  • Cardiology
  • Sepsis Pathophysiology
  • Molecular Biology

Context:

  • Severe sepsis and septic shock frequently lead to myocardial dysfunction.
  • This cardiac depression is observed early in most patients, characterized by biventricular alterations.
  • It occurs alongside a hyperdynamic state dependent on fluid loading.

Purpose:

  • To review the diagnostic procedures for sepsis-induced myocardial depression.
  • To elucidate the molecular and cellular pathways underlying this cardiac dysfunction.
  • To explore the role of circulating mediators and cellular mechanisms in myocardial depression.

Summary:

  • Sepsis-induced myocardial depression is a common early finding in severe sepsis and septic shock.
  • It is characterized by biventricular dysfunction, not caused by hypoperfusion or structural damage.

  • The condition is linked to circulating mediators like cytokines and involves cellular mechanisms such as apoptosis and calcium homeostasis abnormalities.
  • Recovery typically occurs within 7-10 days in survivors.

    • Impact:

    • Provides a comprehensive overview of sepsis-induced myocardial depression.
    • Highlights the importance of understanding molecular and cellular mechanisms for diagnosis and treatment.
    • Informs clinical practice regarding the management and prognosis of cardiac dysfunction in sepsis.
