AB  - BACKGROUND: Current triage methods for chest pain patients typically utilize
      symptoms, electrocardiogram (ECG), and vital sign data, requiring interpretation 
      by dedicated triage clinicians. In contrast, we aimed to create a quickly
      obtainable model integrating the objective parameters of heart rate variability
      (HRV), troponin, ECG, and vital signs to improve accuracy and efficiency of
      triage for chest pain patients in the emergency department (ED). METHODS: Adult
      patients presenting to the ED with chest pain from September 2010 to July 2015
      were conveniently recruited. The primary outcome was a composite of
      revascularization, death, cardiac arrest, cardiogenic shock, or lethal arrhythmia
      within 72-h of presentation to the ED. To create the chest pain triage (CPT)
      model, logistic regression was done where potential covariates comprised of vital
      signs, ECG parameters, troponin, and HRV measures. Current triage methods at our 
      institution and modified early warning score (MEWS) were used as comparators.
      RESULTS: A total of 797 patients were included for final analysis of which 146
      patients (18.3%) met the primary outcome. Patients were an average age of 60years
      old, 68% male, and 56% triaged to the most acute category. The model consisted of
      five parameters: pain score, ST-elevation, ST-depression, detrended fluctuation
      analysis (DFA) alpha1, and troponin. CPT model>0.09, CPT model>0.15, current
      triage methods, and MEWS>/=2 had sensitivities of 86%, 74%, 75%, and 23%,
      respectively, and specificities of 45%, 71%, 48%, and 78%, respectively.
      CONCLUSION: The CPT model may improve current clinical triage protocols for chest
      pain patients in the ED.
