BACKGROUND:The accelerated diagnostic protocol(ADP)using the Emergency Department Assessment of Chest pain Score(EDACS-ADP),a tool to identify patients at low risk of a major adverse cardiac event(MACE)among patients presenting with chest pain to the emergency department,was developed using a contemporary troponin assay.This study was performed to validate and compare the performance of the EDACS-ADP incorporating high-sensitivity cardiac troponin I between patients who had a 30-day MACE with and without unstable angina(MACE I and Ⅱ,respectively).METHODS:A single-center prospective observational study of adult patients presenting with chest pain suggestive of acute coronary syndrome was performed.The performance of EDACS-ADP in predicting MACE was assessed by calculating the sensitivity and negative predictive value.RESULTS:Of the 1,304 patients prospectively enrolled,399(30.6％;95％confidence interval[95％CI]:27.7％-33.8％)were considered low-risk using the EDACS-ADP.Among them,the rates of MACE I andⅡ were 1.3％(5/399)and 1.0％(4/399),respectively.The EDACS-ADP showed sensitivities and negative predictive values of 98.8％(95％CI:97.2％-99.6％)and 98.7％(95％CI:97.0％-99.5％)for MACE I and 98.7％(95％CI:96.8％-99.7％)and 99.0％(95％CI:97.4％-99.6％)for MACE Ⅱ,respectively.CONCLUSION:EDACS-ADP could help identify patients as safe for early discharge.However,when unstable angina was added to the outcome,the 30-day MACE rate among the designated low-risk patients remained above the level acceptable for early discharge without further evaluation.
