Cardiogenic Shock Mortality Risk (CardShock) — free guideline decision tool
The CardShock score uses seven admission variables to predict in-hospital mortality in cardiogenic shock.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Age > 75 yr | No |
|---|---|
| Confusion at admission | No |
| Prior MI or CABG | No |
| ACS etiology | No |
| Left ventricular ejection fraction < 40% | No |
| Blood lactate | < 2 mmol/L (0) |
| eGFR | > 60 (0) |
→CardShock0 pts
- Class：0 pts (0–9) → Low risk (in-hospital mortality ≈9%)
- Management direction：Low risk: standard cardiogenic-shock management, monitor for change and reassess promptly
- Note：7 variables integrate age, mental status, cardiac history/etiology, LV function, perfusion (lactate), and renal function (eGFR). AUC ≈ 0.85 (development) / 0.71 (validation). Complementary to SCAI staging and the IABP-SHOCK II score
| Age > 75 yr | Yes (1) |
|---|---|
| Confusion at admission | Yes (1) |
| Prior MI or CABG | Yes (1) |
| ACS etiology | Yes (1) |
| Left ventricular ejection fraction < 40% | Yes (1) |
| Blood lactate | > 4 mmol/L (2) |
| eGFR | < 30 (2) |
→CardShock9 pts
- Class：9 pts (0–9) → High risk (in-hospital mortality ≈77%)
- Management direction：High risk: early multidisciplinary shock team, assess mechanical circulatory support, transfer to an experienced center; intensify monitoring and organ support
- Note：7 variables integrate age, mental status, cardiac history/etiology, LV function, perfusion (lactate), and renal function (eGFR). AUC ≈ 0.85 (development) / 0.71 (validation). Complementary to SCAI staging and the IABP-SHOCK II score
Common questions
What is Cardiogenic Shock Mortality Risk (CardShock)?
The CardShock score uses seven admission variables to predict in-hospital mortality in cardiogenic shock.
How is Cardiogenic Shock Mortality Risk (CardShock) calculated? What is the core formula?
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.
When is Cardiogenic Shock Mortality Risk (CardShock) used?
Use early in cardiogenic shock to stratify mortality risk and inform escalation and transfer decisions.
What are the key clinical points for Cardiogenic Shock Mortality Risk (CardShock)?
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.
What are the limits and cautions when using Cardiogenic Shock Mortality Risk (CardShock)?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
How is Cardiogenic Shock Mortality Risk (CardShock) calculated in practice? Can you show a worked example?
