Emergency Medicine Case Series: Episode 1
Manage episode 371497159 series 2912105
Panel:
Pramod Chandru and Shreyas Iyer.
Case Summary:
- 61-year-old male presenting with 2 distinct episodes of shortness of breath, chest pain, and associated presyncope.
- Asymptomatic by the time of arrival to the emergency department.
- ECG and observations at triage were unremarkable.
- No recent travel or recent major surgeries.
- Initial troponin and serial troponin were 80ng/L.
- D-dimer was ordered given static troponin and the nature of symptoms: 0.58.
- Although this D-dimer was negative when age-adjusted, a V/Q scan was pursued as the patient was not felt to fit a ‘low risk’ pre-test probability for PE (IV contrast shortage dictated V/Q over CTPA).
- Bilateral segmental pulmonary PE identified on V/Q scan with mild right heart strain evident on subsequent CTPA and TTE.
Key Discussion Points:
- If a case does not follow the usual ‘pattern’ of your initial diagnosis, consider alternate aetiologies.
- There are many tools available for risk-stratifying PE including PERC, age-adjusted D-dimer, and the YEARS diagnostic pathway. However, the way in which to appropriately utilize these tools is nuanced.
- A paper published in JAMA in December 2021 demonstrates some ways in which these tools can be used together (see first reference below).
- The PESI score (even prior to definitive diagnosis) can be useful to risk stratify patients with possible PE and help determine their disposition.
Take-Home Points:
- Pre-test probability is incredibly important, particularly in entities such as PE where only highly invasive imaging modalities are diagnostic.
- Having a structured approach to protect yourself from your own mistakes is extremely important (such as a hypothesis and hypothesis testing approach).
