Key result
Age shock index and age-modified shock index strongly predicted in-hospital cardiac mortality (age SI: OR 1.05, P<0.001; age MSI: OR 1.04, P<0.001), performing comparably to the GRACE score.
Why the study?
The predictive values of age SI and age MSI in STEMI patients undergoing emergency PCI had rarely been reported, especially compared with SI, MSI, and the GRACE risk score.
Do age SI and age MSI predict outcomes better than SI, MSI, and GRACE score in STEMI patients undergoing emergency PCI?
Population
983 STEMI patients undergoing emergency PCI
Comparison
Predictive value of age SI and age MSI vs SI, MSI, and GRACE score

May support age SI/MSI for bedside mortality risk stratification in STEMI PCI; leaves open superiority to GRACE pending prospective validation.

Do age SI and age MSI predict outcomes better than SI, MSI, and GRACE score in STEMI patients undergoing emergency PCI?
Effect estimate: OR 1.05
p-value: p=<0.001
Age SI and age MSI are simple, convenient indicators that offer comparable predictive value to the GRACE score for mortality in STEMI patients undergoing emergency PCI.
Zhou et al. (2019) conducted a cohort in ST-segment elevation myocardial infarction (STEMI) (n=983). Age shock index (age SI) and age-modified shock index (age MSI) vs. SI, MSI, and GRACE risk score was evaluated on in-hospital cardiovascular events, and 6-month and long-term all-cause mortality (OR 1.05, p=<0.001). Age shock index and age-modified shock index strongly predicted in-hospital cardiac mortality (age SI: OR 1.05, P<0.001; age MSI: OR 1.04, P<0.001), performing comparably to the GRACE score.
