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 | 2–4 mmol/L (1) |
| eGFR | 30–60 (1) |
→CardShock2 pts
- Class：2 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

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?
Management follows current guidelines and local protocols; this page gives no management recommendation.
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). 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.
Does Cardiogenic Shock Mortality Risk (CardShock) upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Cardiogenic Shock Mortality Risk (CardShock) calculated in practice? Can you show a worked example?
