How to manage hepatic dysfunction due to cardiogenic shock?

From the Guidelines

Management of hepatic dysfunction due to cardiogenic shock requires immediate attention to both the cardiac and hepatic components, with a focus on stabilizing the underlying cardiac function through inotropic support and optimizing perfusion pressure. The most recent and highest quality study, 1, suggests that intravenous inotropic support can increase cardiac output and improve hemodynamics in patients presenting with cardiogenic shock. Key considerations include:

• Optimizing cardiac output through inotropic support with medications like dobutamine (starting at 2-20 mcg/kg/min) or milrinone (0.375-0.75 mcg/kg/min) 1
• Using vasopressors such as norepinephrine (0.01-3 mcg/kg/min) to maintain adequate perfusion pressure 1
• Ensuring adequate volume status while avoiding fluid overload that could worsen cardiac function 1
• Considering mechanical circulatory support with devices like intra-aortic balloon pump or extracorporeal membrane oxygenation for severe cases 1
• Protecting the liver by avoiding hepatotoxic medications, monitoring liver function tests closely, maintaining glucose levels, and correcting coagulation abnormalities with fresh frozen plasma if needed 1
• Using continuous renal replacement therapy to manage fluid balance and remove toxins in cases with concomitant kidney dysfunction 1 The liver dysfunction occurs because cardiogenic shock reduces hepatic perfusion, leading to centrilobular necrosis and elevated liver enzymes, and prompt restoration of cardiac output is crucial as the liver has remarkable regenerative capacity if adequate blood flow is restored before extensive damage occurs 1. Team-based cardiogenic shock management, including a multidisciplinary team experienced in shock, is also recommended to optimize patient outcomes 1.

From the Research

Management of Hepatic Dysfunction due to Cardiogenic Shock

• Hepatic dysfunction is a key feature of cardiogenic shock, and its management requires active monitoring of organ function and knowledge of criteria for detection and classification of organ injury 2.
• The use of intra-aortic balloon pump (IABP) for counterpulsation may be employed to improve hemodynamics and stabilize the patient with cardiogenic shock, including those with hepatic dysfunction 3, 4.
• Experts recommend a multidisciplinary approach to the management of cardiogenic shock, including the use of vasoactive drugs, mechanical assistance, and general treatments, as well as specialized and experienced medical teams 5.
• Monitoring renal and hepatic function and identifying injury and dysfunction of these organs is essential for the management and mortality risk assessment of patients in cardiogenic shock 2.
• Case reports have shown that hepatic failure due to cardiogenic shock can be reversible with proper management, and long-term survival with return of normal liver function is possible 6.

Key Considerations

• The SOFA score for prediction of mortality in the critically ill incorporates organ injury and can be used to assess the severity of hepatic dysfunction in cardiogenic shock 2.
• Biomarkers reflecting different pathways activated in cardiogenic shock may correlate with severity of organ dysfunction and improve risk prediction in cardiogenic shock 2.
• A multidisciplinary technical platform and specialized medical teams are necessary for the management of cardiogenic shock, including hepatic dysfunction 5.
