SCAI SHOCK Cardiogenic-Shock Stage
SCAI SHOCK cardiogenic-shock stage A–E (Naidu 2022; Kadosh/Kapur operationalization) from systolic BP, lactate, and the level of vasoactive/mechanical support, with a cardiac-arrest modifier.
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Systolic blood pressure
- 80 mmHg
- Serum lactate
- 3 mmol/L
- Vasoactive / mechanical support level
- One intervention (1 vasopressor/inotrope or 1 device)
Result: SCAI stage C (classic) — associated in-hospital mortality signal ~12.4% (Mayo CICU).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Stages
- A at risk, B beginning, C classic, D deteriorating, E extremis — from hypotension, lactate, and support level, with a cardiac-arrest modifier.
- Mortality
- Jentzer 2019 Mayo CICU in-hospital mortality: A 3.0%, B 7.1%, C 12.4%, D 40.4%, E 67.0%. A severity vocabulary, not an order.
What you enter
- Systolic blood pressure
- Serum lactate
- Vasoactive / mechanical support level
- Cardiac arrest / circulatory collapse
- Hypotension/hypoperfusion persisting despite initial support
