BackgroundSyncope is a possible but little known presenting manifestation of acute pulmonary embolism (PE). The importance of syncope at the presentation of acute PE is not known.ObjectivesTo report the frequency and to establish the prognostic significance of syncope at the presentation of acute PE.MethodsA retrospective review of the records of 154 consecutive patients admitted to an Internal Medicine service with acute PE.ResultsFourteen patients with acute PE (9.1%) had syncope at presentation. Epidemiological and clinical characteristics (including respiratory failure, right heart failure and arterial hypotension), and hospital mortality were similar in patients with or without syncope.ConclusionsSyncope is not an uncommonly presenting manifestation of acute PE. Patients with acute PE and syncope have similar characteristics to those without syncope. Syncope does not seem to determine a poor prognosis.
