237. CCC: Approach to LV Predominant Cardiogenic Shock with Dr. Shashank Sinha

Cardionerds: A Cardiology Podcast

Cardiogenic shock (CS) remains a complex, multifactorial syndrome associated with significant morbidity and mortality. The CardioNerds Critical Care Cardiology Series tackles this important syndrome in a series of several episodes including: LV-predominant Shock, RV-predominant Shock, and Bi-ventricular Shock. In this episode, we review the definitions, pathophysiology, evaluation, and contemporary management, including use of inotropes and mechanical circulatory support, of left ventricular (LV) predominant CS. Series co-chairs Dr. Eunice Dugan and Dr. Karan Desai along with CardioNerds Co-founders Dr. Amit Goyal and Dr. Daniel Ambinder were joined by FIT lead, Dr. Vanessa Blumer, the recipient of the AHA 2021 Laennec Fellow in Training Clinician Award and currently pursuing Advanced Heart Failure and Transplant fellowship at the Cleveland Clinic. Our episode expert is Dr. Shashank Sinha, an Advanced Heart Failure, Mechanical Circulatory Support, and Cardiac Transplant cardiologist, Medical Director of the Cardiac Intensive Care Unit, and Director of the Cardiovascular Critical Care Research Program at INOVA Fairfax Hospital. His illustrious career accomplishments include being a Steering Committee member and site Principal Investigator for the multicenter Cardiogenic Shock Working Group and Critical Care Cardiology Trials Network.

The CardioNerds Cardiac Critical Care Series is a multi-institutional collaboration made possible by contributions of stellar fellow leads and expert faculty from several programs, led by series co-chairs, Dr. Mark Belkin, Dr. Eunice Dugan, Dr. Karan Desai, and Dr. Yoav Karpenshif.

Pearls and Quotes - LV Predominant Cardiogenic Shock LV-CS is complex! It is important to recognize that the pathophysiology of heart failure-related cardiogenic shock (HF-CS) is distinct from that of acute myocardial infarction (AMI-CS), and also crucial to differentiate between LV-dominant, right ventricular (RV)-dominant and biventricular (BiV)-shock.The SCAI SHOCK Stage Classification provides a unified and standardized vocabulary when assessing severity of CS, and facilitates communication about the diagnosis, presentation, and evolving nature of CS.Norepinephrine is considered the initial vasopressor of choice in most CS patients; the initial inotrope choice is a bit more nuanced!When considering mechanical circulatory support (MCS) for LV shock, high-quality data to guide therapy is lacking but one must always consider “the right patient, for the right device, at the right time” and remember that “pumps pump blood, decisions save lives”.Multidisciplinary, team-based care is paramount to improving survival of the critically ill patient with CS.

CS is a hemodynamically complex and multifactorial syndrome, one of the most common indications for admission to a cardiac intensive care unit, with short-term mortality ranging from 35-50%.It is defined by systemic hypoperfusion and tissue hypoxia due to a primary cardiac insult or dysfunction.Clinical criteria used to define CS typically include evidence of hypotension (classically defined as SBP < 90 mmHg for 30 minutes and/or use of vasopressors, inotropes, or MCS to maintain systolic blood pressure > 90 mmHg) AND evidence of end-organ hypoperfusion (for example, serum lactic acid > 2 mmol/L, acute kidney injury, acute liver injury, altered mental status) in the setting of acute coronary syndrome or acute decompensated heart failure.Laboratory markers,
