MDCAST: The Stubborn Lethality of Cardiogenic Shock

This episode provides an overview of cardiogenic shock and explains why it remains such a major problem despite decades of progress in treating acute coronary syndromes. Dr. Mike Lauria notes that while STEMI and other ACS outcomes have improved dramatically with better systems, PCI, and modern cardiac care, mortality from cardiogenic shock has stayed stubbornly high. A central theme is that cardiogenic shock is becoming more common, especially among more medically complex patients with chronic heart failure and prior cardiac disease, and that critical care transport teams are increasingly encountering these patients because so many require transfer to higher-level centers. A major focus of the episode is the modern framework for thinking about shock, especially the SCAI stages A through E , which describe cardiogenic shock as a spectrum rather than a simple yes-or-no diagnosis. Dr. Lauria emphasizes that this shared language helps clinicians identify patients earlier, communicate severity more clearly, and escalate care before they progress into multi-organ failure. Dr. Lauria argues that early recognition, rapid team-based decision-making, and transfer to experienced shock centers are some of the most promising ways to improve outcomes, particularly because late interventions often fail once the patient has already tipped into severe end-organ injury. From a transport perspective, the episode frames care around recognition, resuscitation, and retrieval. Clinicians are encouraged to identify deterioration early, support perfusion by maintaining MAP, optimize oxygenation and ventilation, think carefully about volume status, add inotropic support when needed, and pay close attention to whether existing mechanical circulatory support is truly sufficient. Just as importantly, Dr. Lauria stresses the logistical and systems side of transport: moving quickly but safely, anticipating equipment and oxygen needs, and advocating for the patient to reach the right destination the first time, especially if advanced support such as Impella or ECMO may soon be needed. Key points Cardiogenic shock remains a high-mortality condition even though outcomes for acute coronary syndromes have improved substantially. It is increasingly common, especially among complex patients with chronic heart failure and prior cardiac disease . The SCAI shock stages (A-E) provide a practical shared language for identifying severity and guiding escalation of care. Early recognition, shock teams, and transfer to experienced cardiogenic shock centers may improve outcomes by preventing delayed intervention. For transport teams, priorities include supporting MAP, optimizing oxygenation/ventilation, considering volume status and inotropy, checking device adequacy, and getting the patient to the right place quickly and safely .
