Abstract:
Objective:To compare the ability of Vancouver chest pain rule, Triage Rule-out Using high-Sensitivity Troponin accelerated diagnostic protocol and Emergency Department Assessment of Chest pain Score accelerated diagnostic protocol in rapid assessment of patients with chest pain.Methods:Patients with chest pain suggestive of acute coronary syndrome were recruited from January 2017 to February 2017 in Emergency Department of Tianjin Medical University General Hospital. Patients were stratified into various risk groups with Vancouver chest pain rule, Triage Rule-out Using high-Sensitivity Troponin accelerated diagnostic protocol and Emergency Department Assessment of Chest pain Score accelerated diagnostic protocol. The end point was acute myocardial infarction (AMI) within 30 days.Results:A total of 134 patients were enrolled. Fifty-seven patients were preliminary classified as a low risk for suitable discharge by Triage Rule-out Using high-Sensitivity Troponin accelerated diagnostic protocol, and one of them had AMI within 30 days. The sensitivity of stratifying low-risk patient was 83.3%, the specificity was 43.8%, and the negative predictive value was 98.2%. Fifty-one patients were preliminary classified as a low risk for suitable discharge by Emergency Department Assessment of Chest pain Score accelerated diagnostic protocol, and none of them had AMI within 30 days; the sensitivity of stratifying low risk patient was 100%, the specificity was 39.8%, and the negative predictive value was 100%. Twenty-four patients were preliminary classified as a low risk for suitable discharge by Vancouver chest pain rule, and none of them had AMI within 30 days; the sensitivity of stratifying low risk patient was 100%, the specificity was 18.8%, and the negative predictive value was 100%.Conclusions:Using accelerated diagnostic protocols to stratify emergency department patients with chest pain achieved early and safe emergency department discharge. The Emergency Department Assessment of Chest pain Score accelerated diagnostic protocol stratified more than 30% of low-risk patient, with a sensitivity of no less than 98% and a specificity of no less than 99.5%.
