🫀 Cardiogenic Shock Mortality Risk (CardShock)
The CardShock score uses seven admission variables to predict in-hospital mortality in cardiogenic shock.
Cardiogenic Shock Mortality Risk (CardShock)
Age > 75 yr
Confusion at admission
Prior MI or CABG
ACS etiology
Left ventricular ejection fraction < 40%
Blood lactate
eGFR
When to use
Use early in cardiogenic shock to stratify mortality risk and inform escalation and transfer decisions.
How it works
Points (0–9) from age > 75, confusion, prior MI/CABG, ACS etiology, LVEF < 40%, lactate, and eGFR; low 0–3 (≈9%), intermediate 4–5 (≈36%), high 6–9 (≈77%) in-hospital mortality.
Key points
- CardShock complements SCAI staging and the IABP-SHOCK II score, adding a quantitative early-mortality estimate (original synthesis · not guideline verbatim).
- High scores justify early shock-team involvement and consideration of mechanical circulatory support.
- Lactate and eGFR carry up to 2 points each, reflecting the weight of perfusion and renal function.
