Short- and long-term prognosis of syncope, risk factors, and role of hospital admission: results from the STePS (Short-Term Prognosis of Syncope) study.

Objective: We sought to assess short- and long-term prognosis of syncope and associated risk factors.

Background: Syncope is a common clinical event, but our knowledge of its short-term outcome is largely incomplete. Further, it is unknown whether hospital admission might positively affect a patient's syncope prognosis.
