CardShock Risk Score (cardiogenic shock mortality)
CardShock risk score (Harjola 2015): age > 75 (1) + confusion (1) + prior MI/CABG (1) + ACS etiology (1) + LVEF < 40 (1) + lactate band + eGFR band; the 0-9 sum maps to graded in-hospital mortality.

Example
- Age > 75 years
- Yes
- Confusion at presentation
- Yes
- Previous MI or CABG
- Yes
- ACS etiology
- Yes
- LVEF < 40%
- Yes
- Blood lactate
- 5 mmol/L
- eGFR
- 25 mL/min/1.73m^2
Result: CardShock 9/9: high risk (~77% in-hospital mortality).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Score 0-9
- age > 75 (1), confusion (1), prior MI/CABG (1), ACS etiology (1), EF < 40% (1), lactate (2-4 = 1, > 4 = 2), eGFR (30-60 = 1, < 30 = 2).
- Mortality
- 0-3 low (~8.7%), 4-5 intermediate (~36%), 6-9 high (~77%) in-hospital mortality. The deterministic substitute for the excluded gestalt SCAI staging.
What you enter
- Age > 75 years
