Key result
High and intermediate risk PE linked to ~23% lower DVT incidence versus low risk PE.
Why the study?
The association of clinical risk factors, particularly deep vein thrombosis, with risk stratification for pulmonary embolism remained to be identified.
Is there an association between deep vein thrombosis characteristics and risk stratification in patients with pulmonary embolism?
Population
392 patients with pulmonary embolism
Comparison
PE risk stratification groups (high vs intermediate vs low risk by ESC criteria) and DVT characteristics
Design
Retrospective study

Higher-risk PE linked to lower DVT incidence; leaves open whether asymptomatic DVT independently predicts severity and requires prospective validation.
Observational (n=392)
Is there an association between deep vein thrombosis characteristics and risk stratification in patients with pulmonary embolism?
Absolute Event Rate: 67.2% vs 87.8%
p-value: p=< .0001
In patients with pulmonary embolism, asymptomatic DVT is an independent risk factor for high and intermediate risk PE, despite a lower overall incidence of DVT in these higher-risk groups compared to low-risk PE.
Wang et al. (2020) conducted an observational in Pulmonary embolism (n=392). High and intermediate risk pulmonary embolism vs. Low risk pulmonary embolism was evaluated on Incidence of deep vein thrombosis (DVT) (p=< .0001). High and intermediate risk pulmonary embolism was associated with a lower incidence of deep vein thrombosis compared to low risk pulmonary embolism (67.2% vs 87.8%, P<.0001).
