Podcast # 460: Hunting for PE in Syncope

Author:  Michael Hunt, MD

Educational Pearls:

 

  • Most causes of syncope are benign
  • Pulmonary embolism can result in syncope and is life threatening
  • A recent study of Canadian and US ED patients with syncope showed that 0.4% of patients had a PE at 30 day follow-up
  • PE should always be considered in cases of syncope but overall is a rare cause

 

Editor’s note: this study puts to rest a previous study from 2016 that reported a rate of PE in syncope as high as 1 in 6 in patients admitted to syncope – which was met with much skepticism based on clinical practice.
