  • Title: Evolving Concepts in Diagnosis and Management of Cardiogenic Shock.
    Author: Bellumkonda L, Gul B, Masri SC.
    Journal: Am J Cardiol; 2018 Sep 15; 122(6):1104-1110. PubMed ID: 30072134.
    Abstract:
    Despite efforts at early revascularization in acute coronary syndrome and advancing technologies in the field of temporary mechanical circulatory support (TMCS), the mortality from cardiogenic shock (CS) remains very high. Treatment of these patients involves understanding the trajectory of the condition and making complex decisions regarding the appropriate selection of medical and device therapies. The current definition of CS is not universally applicable and defines shock in absolute terms. CS should be thought of as a continuum rather than a binary diagnosis and is best defined as a clinical syndrome of tissue hypoperfusion resulting from cardiac dysfunction. Early intervention with appropriate timing and selection of apposite TMCS device may be the key to improving outcomes. TMCS device selection is a complex process requiring consideration of the severity of CS, patient-specific risks, technical limitations, overall goals of care, and assessment of futility of care. In this review, we discuss identification and pathophysiology of CS, and critically review acute management strategies, both medical and mechanical therapies and outline areas that need further investigation.
