Decoding Cardiogenic Shock: Assessing Shock Index and Its Variants as Prognostic Indicators for In-Hospital Mortality
Authors' conclusion
Shock index and its variants, especially ASI, AMSI, and SIC, may be helpful in predicting in-hospital mortality in CS patients.
Study context
- Population
- Patients with cardiogenic shock866 (67.6%) survived to discharge
- Participants
- 1,282 patients
- Exposure
- Shock index (SI) and its variants as prognostic indicators of in-hospital mortality
- Outcome
- Predictive accuracy (ROC AUC) of shock indices for in-hospital mortality
- Follow-up
- In-hospital
