Summary
Brief summary
Syncope is a major health problem. In the emergency department (ED), the management of patients with syncope still remains a clinical challenge because underlying diseases and prognosis can be extremely various. Structural heart disease and primary electrical disorders are major risk factors for sudden cardiac death and mortality in patients with syncope. In contrast, patients with reflex syncope and exclusion of structural heart disease have an excellent prognosis.

Therefore The investigators test the hypothesis that the use of a meticulous patient history, clinical examination and novel biomarkers can improve the rapid and accurate diagnosis of cardiac syncope in patients presenting to the ED and is able to improve risk stratification regarding adverse outcomes.

The prospective multicenter cohort study is designed to enroll 720 patients presenting with transient loss of consciousness within the last 12 hours to the ED. Blood samples for the measurement of novel biomarkers will be obtained at presentation.

All patients will be contacted by phone at 6, 12 and 24 months to determine major adverse events (death, resuscitation, recurrence of syncope, hospitalization for syncope).
