Background: New diagnosis, risk stratification, and treatment strategies became recently available for patients with acute pulmonary embolism (PE) leading to changes in clinical practice and potentially influencing short-term patients' outcomes.
Research Question: The COntemporary management of PE (COPE) study is aimed at assessing the contemporary clinical management and outcomes in patients with acute symptomatic PE.
Study Design And Methods: Prospective, noninterventional, multicenter study. The co-primary study outcomes, in-hospital and 30-day death, were reported overall and by risk categories according to the European Society of Cardiology (ESC) and American Heart Association guidelines.
Results: Among 5,213 study patients, PE was confirmed by computed tomography in 96.3%. In-hospital, 289 patients underwent reperfusion (5.5%), 92.1% received parenteral anticoagulants; at discharge, 75.6% received direct oral anticoagulants and 6.7% vitamin K antagonists. In-hospital and 30-day mortalities were 3.4 and 4.8%, respectively. In-hospital death occurred in 20.3% high-risk patients (177), in 4.0% intermediate-risk patients (3,281), and in 0.5% low-risk patients (1,702) according to ESC guidelines. Further stratification in intermediate-high and intermediate-low risk patients did not reach statistical significance, but intermediate-risk patients with sPESI > 0 alone had lower mortality compared to those with one or both among right ventricular dilation at echocardiography or increased troponin. Death or clinical deterioration occurred in 1.5, 5.0, and 9.4% of patients at low, intermediate-low, and intermediate-high risk for death according to ESC guidelines.
Conclusion: For the majority of patients with PE, contemporary initial management includes risk stratification and treatment with direct oral anticoagulants. In-hospital mortality remains high in intermediate and high-risk patients calling for and informing research focused on its reduction.
