Comparison of Global Registry of Acute Coronary Events and Rapid Emergency Medicine Scores in In-Hospital Mortality of Patients Admitted to the Emergency Service and Diagnosed with Non-ST-Segment Elevation Myocardial Infarction.

This article focuses on comparing the Rapid Emergency Medicine Score (REMS) and the Global Registry of Acute Coronary Events (GRACE) score for predicting in-hospital mortality in patients with non-ST-elevation myocardial infarction (NSTEMI). The study found that REMS, a simple scoring system based on physiological parameters, demonstrated higher sensitivity (100%) and specificity (76%) than the GRACE score (sensitivity 88%, specificity 65%) in mortality prediction, with an area under the curve (AUC) of 0.89 versus 0.79 for GRACE, though this difference was not statistically significant. The authors suggest that REMS can be effectively used in emergency departments for early risk stratification of NSTEMI patients due to its ease of use and rapid applicability. Limitations include the study’s retrospective design, single-center setting, and relatively small sample size.
