Summary

Syncope, or fainting, is a common symptom in acute pulmonary embolism (PE). This study found that syncope at presentation does not indicate a worse prognosis for PE patients.

Area of Science:

  • Cardiology
  • Pulmonary Medicine
  • Internal Medicine

Background:

  • Syncope is an underrecognized symptom of acute pulmonary embolism (PE).
  • The prognostic value of syncope in acute PE presentation is not well-established.

Purpose of the Study:

  • To determine the frequency of syncope in patients with acute PE.
  • To assess the prognostic significance of syncope at the time of acute PE diagnosis.

Main Methods:

  • Retrospective analysis of 154 consecutive patients admitted with acute PE.
  • Review of patient records to identify syncope at presentation and clinical characteristics.

Main Results:

  • Syncope occurred in 9.1% of acute PE patients.

  • No significant differences in clinical presentation (respiratory failure, hypotension) or hospital mortality were observed between patients with and without syncope.

    • Conclusions:

    • Syncope is a notable, though not rare, presenting symptom of acute PE.
    • Syncope in acute PE patients does not appear to be associated with poorer outcomes or distinct clinical features.
