Key result
Admission shock index ≥ 0.7 predicts ~290% higher in-hospital mortality in STEMI patients.
Why the study?
Early identification of high-risk STEMI patients helps prevent complications, but the predictive value of the admission shock index for in-hospital and one-year outcomes needed assessment.
Does an admission shock index ≥ 0.7 predict in-hospital mortality, one-year mortality, and MACE in patients with STEMI?
Cohort (n=867)
No
Does an admission shock index ≥ 0.7 predict in-hospital mortality, one-year mortality, and MACE in patients with STEMI?
Effect estimate: HR 3.9 (95% CI 2.037-7.46)
Absolute Event Rate: 18.8% vs 3.6%
p-value: p=<0.001
Admission shock index is an independent predictor of in-hospital mortality and MACE in patients presenting with STEMI, serving as a valuable bedside risk-stratification tool.

May support shock index for early STEMI risk stratification; hypothesis-generating and requires prospective validation.
Ferdowsain et al. (2025) conducted a cohort in ST-segment elevation myocardial infarction (STEMI) (n=867). Elevated Shock Index (SI ≥ 0.7) vs. Normal Shock Index (SI < 0.7) was evaluated on In-hospital mortality (HR 3.9, 95% CI 2.037-7.46, p=<0.001). An admission shock index ≥ 0.7 independently predicted in-hospital mortality (HR 3.9) and one-year major adverse cardiovascular events (HR 1.67) in patients with ST-segment elevation myocardial infarction.
