Cardiogenic Shock: SCAI Stages & Stubborn Mortality
Early, staged shock care—not support—drives survival
Cardiogenic shock mortality has stayed ~30–40% because many therapies are only temporizing; outcomes improve when systems use shared SCAI stages for rapid recognition, escalation, and timely center transfer before multi-organ failure.
Positive-pressure ventilation can act hemodynamically
Non-invasive ventilation in early cardiogenic shock can improve mortality and intubation rates by reducing RV preload (less congestion) and providing LV wall support/relative afterload reduction—so it’s not just oxygenation.
Cardiac power output guides escalation decisions
Cardiac power output (CO×MAP/451) better captures under-perfusion than MAP alone; values below ~0.6 suggest the need to increase support or expedite transfer, using invasive/cath data or bedside estimates cautiously.
