    Treating Cardiogenic Shock: A Multidisciplinary Team Approach Achieves Better Outcomes

    Treating Cardiogenic Shock: A Multidisciplinary Team Approach Achieves Better Outcomes

    University of Cincinnati (UC) Medical Center has instituted a team approach for the treatment of acute cardiogenic shock, setting it apart from most medical centers and providing a critical advantage for such acutely ill patients. “With our growing STEMI volume, the team identified the need to provide early intervention for the patient in acute cardiogenic shock, much like the ‘golden hour’ for trauma patients,” says Suzanne Bennett, MD, director of anesthesiology critical care and co-founder of the program. “When a patient meets specific criteria for refractory cardiogenic shock, the shock team allows the interventional cardiologist to focus on revascularization while the critical care anesthesiologist provides hemodynamic and respiratory support to prevent the patient’s further deterioration.”

    Timothy Smith, MD, Cardiovascular Critical Care, Interventional Cardiology; Jessica Gummow, CCP, chief perfusionist

    The team, led by David Feldman, MD, PhD, director of clinical services, and Louis B. Louis, IV, MD, FACS, chief of cardiac surgery, has developed selection algorithms and criteria that enable it to respond in a controlled fashion  resulting in optimal patient outcomes.1 The decision to proceed onto advanced mechanical support is not made in isolation, Dr. Feldman says, and the majority of the physician team members must agree prior to the initiation of mechanical circulatory support. “UC Medical Center is one of very few medical centers to have a multidisciplinary shock team to treat patients in acute cardiogenic shock, which provides early patient optimization and likely improves patient survival,” he says.

    Extracorporeal membrane oxygenation (ECMO) is the foundation for mechanical circulatory support in the acute shock setting at UC Medical Center. In the modern era, using ECMO for acute shock is associated with a 41-70% survival,2,3 compared with a less than 20-30% survival without intervention.3,4 In addition to ECMO, there are other advanced mechanical circulatory support options available to the UC Medical Center shock team, which decides in a multidisciplinary fashion which modality is best for the individual patient. The field of temporary cardiac circulatory support devices is growing rapidly, and programs must stay on the cutting edge to be able to provide excellent, quality care to this gravely ill patient population.

    Dr. Smith is preparing to insert the venous cannula for the circuit while Jessica Gummow and Dr. Simeone prepare the circuit to be attached to the cannula.

    Once safely on mechanical circulatory support, the patient is transferred to the Cardiovascular Intensive Care Unit (CVICU) where he/she will be managed by a multidisciplinary team who will determine whether the patient can recover cardiac function, or is a candidate for more advanced therapies, such as a long-term implantable left ventricular assist device (LVAD), and/or eventual heart transplantation.

    The rapid deployment of a multidisciplinary team to provide immediate cardiovascular support for patients who have life-threatening shock is one more way UC Medical Center is demonstrating its commitment to advancing the field of cardiovascular medicine, and providing a resource for the community in a collaborative fashion, leveraging the expertise and professionalism of its clinician scientists.
