Key result
A STEMI shock index ≥182 was associated with a 10-fold higher risk of in-hospital death compared to an index <182, demonstrating strong prognostic ability (C statistic 0.870).
Why the study?
Existing shock indices predict short-term mortality in STEMI, but whether invasively measured hemodynamics improves their prognostic ability was unknown.
Does a novel shock index incorporating invasive hemodynamics (STEMI SI) predict mortality in patients with STEMI undergoing primary PCI?
Population
510 patients undergoing primary PCI
Comparison
STEMI SI >=182 vs STEMI SI <182
Design
Single-center study
Follow-up

Odds Ratio: 10
McKenzie et al. (2021) conducted an observational in ST-elevation myocardial infarction (STEMI) (n=510). STEMI shock index ≥182 vs. STEMI shock index <182 was evaluated on In-hospital death (OR 10). A STEMI shock index ≥182 was associated with a 10-fold higher risk of in-hospital death compared to an index <182, demonstrating strong prognostic ability (C statistic 0.870).
