In Brief:
983 ST-segment elevation myocardial infarction (STEMI) patients undergoing emergency percutaneous coronary intervention (PCI) between January 2014 and September 2017 were analyzed in a retrospective cohort study. In multivariate analyses, the predictive values of age shock index (age SI) and age-modified shock index (age MSI) were comparable to that of the Global Registry of Acute Coronary Events (GRACE) risk score but superior to those of SI and MSI for in-hospital cardiac mortality, six-month all-cause mortality, long-term all-cause mortality and post-discharge all-cause mortality. Age SI and age MSI appear to be convenient and simpler indicators than the GRACE score.
