  • Title: Percutaneous ventricular assist devices for cardiogenic shock.
    Author: Cook S, Windecker S.
    Journal: Curr Heart Fail Rep; 2008 Sep; 5(3):163-9. PubMed ID: 18752766.
    Abstract:
    Cardiogenic shock complicates up to 7% of ST-segment elevation myocardial infarctions and 2.5% of non-ST-segment elevation myocardial infarctions, with an associated mortality of 50% to 70%. Primary cardiac pump failure is followed by secondary vital organ hypoperfusion and subsequent activation of various cascade pathways, resulting in a downward spiral leading to multiple organ failure and, ultimately, death. Immediate restoration of cardiac output by means of percutaneous ventricular assist devices restores hemodynamic -stability and is an important advance in the management of patients with severe left ventricular dysfunction and cardiogenic shock. This article reviews available evidence supporting the use of percutaneous ventricular assist devices in patients suffering from cardiogenic shock.
