Methodology · worked example, guidelines & full notes
Staging integrates physical signs, lactate, and hemodynamics — initial staging need not wait for invasive monitoring (original synthesis · not guideline verbatim).
When to use
Use to stage cardiogenic shock at the bedside and guide escalation-of-support and shock-team activation decisions.
How it works
A at-risk → B beginning/pre-shock → C classic (needs intervention) → D deteriorating → E extremis; in-hospital mortality rises ~3% → 7% → 12% → 40% → 67%; cardiac arrest adds an (A) modifier.
Key points
- Staging integrates physical signs, lactate, and hemodynamics — initial staging need not wait for invasive monitoring (original synthesis · not guideline verbatim).
- Shock is dynamic: most patients change stage within 24 h, so serial reassessment drives escalation or de-escalation.
- The (A) cardiac-arrest modifier flags a worse prognostic trajectory independent of the base stage.

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.
| Stage (choose the best fit) | C Classic: hypoperfusion requiring intervention (pressors/inotropes/mechanical support), often CI < 2.2, PCWP > 15, lactate > 2 |
|---|---|
| Cardiac arrest (CPR/defibrillation with coma) | No |
→SCAI stageStage C
- Stage：Stage C (in-hospital mortality ≈12%, Jentzer Mayo CICU cohort)
- Management direction：Pressors/inotropes ± mechanical circulatory support (IABP/Impella/ECMO); right-heart catheter guidance; activate the shock team, consider transfer to a CS center
- Dynamic nature：Cardiogenic shock is a dynamic process: most patients change stage within 24 h — serial reassessment is required to guide escalation/de-escalation of support
| Stage (choose the best fit) | A At risk: ACS or decompensated heart failure, no shock, normal perfusion and blood pressure |
|---|---|
| Cardiac arrest (CPR/defibrillation with coma) | No |
→SCAI stageStage A
- Stage：Stage A (in-hospital mortality ≈3%, Jentzer Mayo CICU cohort)
- Management direction：Monitor, treat the underlying disease (ACS reperfusion / heart-failure optimization), watch closely for progression
- Dynamic nature：Cardiogenic shock is a dynamic process: most patients change stage within 24 h — serial reassessment is required to guide escalation/de-escalation of support

FAQ
Frequently asked questions
- What are the limits and cautions when using Cardiogenic Shock Staging (SCAI SHOCK)?
- 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 Staging (SCAI SHOCK) 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 Staging (SCAI SHOCK) calculated in practice? Can you show a worked example?
- Inputs: Stage (choose the best fit) C Classic: hypoperfusion requiring intervention (pressors/inotropes/mechanical support), often CI < 2.2, PCWP > 15, lactate > 2, Cardiac arrest (CPR/defibrillation with coma) No → Result: SCAI stage Stage C（Stage: Stage C (in-hospital mortality ≈12%, Jentzer Mayo CICU cohort), Management direction: Pressors/inotropes ± mechanical circulatory support (IABP/Impella/ECMO); right-heart catheter guidance; activate the shock team, consider transfer to a CS center, Dynamic nature: Cardiogenic shock is a dynamic process: most patients change stage within 24 h — serial reassessment is required to guide escalation/de-escalation of support） Inputs: Stage (choose the best fit) A At risk: ACS or decompensated heart failure, no shock, normal perfusion and blood pressure, Cardiac arrest (CPR/defibrillation with coma) No → Result: SCAI stage Stage A（Stage: Stage A (in-hospital mortality ≈3%, Jentzer Mayo CICU cohort), Management direction: Monitor, treat the underlying disease (ACS reperfusion / heart-failure optimization), watch closely for progression, Dynamic nature: Cardiogenic shock is a dynamic process: most patients change stage within 24 h — serial reassessment is required to guide escalation/de-escalation of support）
