Hypersensitive Troponin Performance to Identify Syncope at Risk of Serious Adverse Events in the Short Term

Syncope, a frequent reason for emergency room visits and hospitalization, is a symptom of three major etiological entities: cardiac causes, vaso-reflex causes and orthostatic hypotension. The etiological diagnosis is often uncertain and the prognostic assessment orients the outcome of the patient. The vast majority of syncope management costs are related to hospitalizations. Hospitalization in the immediate aftermath of emergency care is justified by a short-term prognosis. The current relevance of hospitalizations and the prognostic assessment of syncope is questioned.
