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.
