Acute cardiac care & resuscitation
Serial Shock Severity Assessment Within 72 Hours After Diagnosis: A Cardiogenic Shock Working Group Report
An erratum to this article was published (J Am Coll Cardiol, 25 Mar 2025 ↗)
Authors' conclusion
Most patients with CS changed SCAI stages within 24 hours from CS diagnosis. Stage B patients were at high risk of worsening shock severity by 24 hours, associated with excess mortality.

Unadjusted mortality by SCAI stage change within 24 hours
- Any SCAI stage worsening
- 44.6%
- Any SCAI stage improving
- 34.2%
- Presenting in or progressing to stage E by 24 hours had the worst prognosis
- Unadjusted
Lactate
- Survivors had lower lactate than nonsurvivors
