Why the study?

Does catastrophic PE increase in-hospital mortality and adverse outcomes compared to high-risk PE?

Structured PICO

Does catastrophic PE increase in-hospital mortality and adverse outcomes compared to high-risk PE?

P

Population

7,931 patients with high-risk or catastrophic pulmonary embolism (PE) identified based on ICD-10 codes. High-risk PE was defined as acute PE with cor pulmonale and cardiogenic shock. Catastrophic PE was defined as high-risk PE with cardiac arrest.

I

Intervention

Catastrophic PE (high-risk PE with cardiac arrest)

C

Comparator

High-risk PE (acute PE with cor pulmonale and cardiogenic shock, without cardiac arrest)

O

Outcome

In-hospital mortalityhard clinical

Implication

Catastrophic pulmonary embolism (presenting with cardiac arrest) is associated with a twofold higher risk of in-hospital mortality and significantly greater resource utilization compared to high-risk PE without cardiac arrest.
