Risk profile and clinical outcome of symptomatic subsegmental acute pulmonary embolism
Why the study?
Does subsegmental pulmonary embolism have a different risk profile and clinical outcome compared to proximal pulmonary embolism or patients without PE?
Population
3728 consecutive patients with clinically suspected pulmonary embolism. PE was confirmed in 748 patients and…

Implication
Similar 3-month VTE and mortality risks in SSPE versus proximal PE; hypothesis-generating and should not yet change practice.
Structured PICO
Does subsegmental pulmonary embolism have a different risk profile and clinical outcome compared to proximal pulmonary embolism or patients without PE?
P
Population
3728 consecutive patients with clinically suspected pulmonary embolism (PE). PE was confirmed in 748 patients (116 with subsegmental PE) and ruled out in 2980 patients.
I
Intervention
Subsegmental pulmonary embolism (SSPE)
C
Comparator
More proximally located pulmonary embolism and patients in whom suspected PE was ruled out
O
Outcome
Prevalence of thromboembolic risk factors, 3-month risk of recurrent venous thromboembolism (VTE), and 3-month mortalityhard clinical
Symptomatic subsegmental pulmonary embolism mimics more proximally located pulmonary embolism in regards to thromboembolic risk profile and 3-month clinical outcomes, including recurrent VTE and mortality.
