This case highlights that pulmonary embolism can present as syncope, even with a low Wells score. High clinical suspicion and diagnostic testing are crucial for identifying rare but life-threatening causes of fainting.
Area of Science:
- Emergency Medicine
- Cardiology
- Pulmonology
Background:
- Syncope is a frequent reason for emergency department visits, necessitating prompt evaluation for potentially fatal etiologies.
- Clinical decision rules aid in risk stratification and guide diagnostic pathways for syncope patients.
Observation:
- An 83-year-old male presented with a 5-minute episode of syncope and hypotension.
- Physical examination was unremarkable, and the Wells score was 0, typically indicating a low probability of pulmonary embolism.
Findings:
- Despite a low Wells score, persistent clinical suspicion for pulmonary embolism led to further testing.
- Elevated D-dimer (13.77 mcg/mL) and computed tomography angiography revealed extensive bilateral pulmonary embolism.
- The patient was initiated on full-dose anticoagulation therapy.
Implications:
- This case underscores the importance of maintaining high clinical suspicion for uncommon causes of syncope, such as pulmonary embolism.
- It emphasizes the value of integrating predictive scoring tools with clinical judgment in diagnosing critical conditions.
- Accurate diagnosis and timely management of pulmonary embolism are vital to prevent patient morbidity and mortality.
