To assess the diagnostic validity of the rapid emergency medical score (REMS) for the risk stratification of acute coronary syndrome (ACS) from non-cardiogenic chest pain. Methods: An observational cross-sectional study was carried out among patients presenting with chest pain to the Emergency Department of Prince Sultan Military Medical City, Riyadh, Kingdom of Saudi Arabia, for 6 months from January to June 2016. All patients, included through non-probability convenience sampling, were assessed using standard protocols for the physiological parameters of the REMS, and ACS was confirmed through electrocardiography, cardiac enzyme testing, and angiography (if needed). Data were analyzed using Statistical Package for Social Sciences software version 15 (SPSS Inc, Chicago, IL, USA). The validity of REMS was determined using a cutoff value of 17. Results: In total, 176 (70.4%) of patients were men with a mean age of 49±8.5 years. The mean REM score of the patients was 9.3±4.5, and a sensitivity of 81.6%, specificity of 90.05%, positive predictive value of 66.67%, and a negative predictive value of 95.26% were obtained. Conclusion: Rapid emergency medical score is a simple and fairly valid tool that may be used for diagnosis of ACS with limited resources in emergency medicine.
