ABSTRACT
BACKGROUND:
Contemporary care patterns/outcomes in high-risk pulmonary embolism (PE) patients are unknown.OBJECTIVES:
This study sought to characterize the management of high-risk PE patients and identify factors associated with poor outcomes.METHODS:
A retrospective analysis of the PERT (Pulmonary Embolism Response Team) Consortium Registry was performed. Patients presenting with intermediate-risk PE, high-risk PE, and catastrophic PE (those with hemodynamic collapse) were identified. Patient characteristics were compared with chi-square testing for categorical covariates and Student's t-test for continuous covariates. Multivariable logistic regression was used to assess associations between clinical characteristics and outcomes in the high-risk population.RESULTS:
Of 5,790 registry patients, 2,976 presented with intermediate-risk PE and 1,442 with high-risk PE. High-risk PE patients were more frequently treated with advanced therapies than intermediate-risk PE patients (41.9% vs 30.2%; P < 0.001). In-hospital mortality (20.6% vs 3.7%; P < 0.001) and major bleeding (10.5% vs. 3.5%; P < 0.001) were more common in high-risk PE. Multivariable regression analysis demonstrated vasopressor use (OR 4.56; 95% CI 3.27-6.38; P < 0.01), extracorporeal membrane oxygenation use (OR 2.86; 95% CI 1.12-7.30; P = 0.03), identified clot-in-transit (OR 2.26; 95% CI 1.13-4.52; P = 0.02), and malignancy (OR = 1.70; 95% CI 1.13-2.56; P = 0.01) as factors associated with in-hospital mortality. Catastrophic PE patients (n = 197 [13.7% of high-risk PE patients]) had higher in-hospital mortality (42.1% vs 17.2%; P < 0.001) than those presenting with noncatastrophic high-risk PE. Extracorporeal membrane oxygenation (13.3% vs. 4.8% P < 0.001) and systemic thrombolysis (25% vs 11.3%; P < 0.001) were used more commonly in catastrophic PE.CONCLUSIONS:
In the largest analysis of high-risk PE patients to date, mortality rates were high with the worst outcomes among patients with hemodynamic collapse.Palavras-chave
