Key result
Combining clinician gestalt with admission ECG and high-sensitivity troponin T achieved 100% sensitivity for ruling out acute myocardial infarction, potentially avoiding 41.7% of admissions.
Why the study?
Does emergency physician clinical gestalt combined with initial troponin and ECG accurately rule out acute myocardial infarction in ED patients with suspected cardiac chest pain?
Population
458 emergency department patients presenting with suspected cardiac chest pain
Comparison
Emergency physician clinical gestalt alone and… vs Serial troponin testing
Design
Cohort, clinicians blinded to outcome

May support AMI rule-out without admission in selected ED patients; hypothesis-generating, needs prospective validation before practice change.
Cohort (n=458)
Blinded to outcome
Does emergency physician clinical gestalt combined with initial troponin and ECG accurately rule out acute myocardial infarction in ED patients with suspected cardiac chest pain?
Effect estimate: AUC 0.76 (95% CI 0.70 to 0.82)
Combining emergency physician clinical gestalt with admission ECG and initial troponin levels can safely rule out acute myocardial infarction with 100% sensitivity, potentially reducing unnecessary hospital admissions.
Body et al. (2014) conducted a cohort in Suspected cardiac chest pain (n=458). Clinician gestalt alone and in combination with initial troponin level and ECG findings was evaluated on Acute myocardial infarction (AMI) (AUC 0.76, 95% CI 0.70 to 0.82). Combining clinician gestalt with admission ECG and high-sensitivity troponin T achieved 100% sensitivity for ruling out acute myocardial infarction, potentially avoiding 41.7% of admissions.
