Top Things to Know: 2026 Guideline for the Evaluation and Management of Acute Pulmonary Embolism in Adults
Published: February 19, 2026
- A new clinical classification scheme is presented, entitled “Acute Pulmonary Embolism Clinical Categories,” with 5 categories (A-E) and subcategories, ranging from low to high risk for adverse outcomes, in order to enhance the precision of severity classification, prognosis assessment, and evidence-based therapeutic decision-making for patients presenting with acute PE.
- Patients with acute PE who are asymptomatic (AHA/ACC PE Category A) can safely be discharged home from the emergency room and do not need to be hospitalized.
- Early hospital discharge is generally recommended for patients with acute PE who are symptomatic but have a low clinical severity score (AHA/ACC PE Category B).
- Symptomatic patients with acute PE and an elevated clinical severity score, including those with elevated biomarkers and/or right ventricular dysfunction (AHA/ACC PE Category C), incipient cardiopulmonary failure (AHA/ACC PE Category D), and those with cardiopulmonary failure characterized by persistent hypotension (AHA/ACC PE Category E) should be hospitalized to optimize treatment strategies.
- Advanced therapies, including systemic thrombolysis, catheter-based thrombolysis, mechanical thrombectomy, and surgical embolectomy are reasonable for patients with acute PE in AHA/ACC PE Category E1 and can be considered for patients with acute PE in AHA/ACC PE Category D1-2.
- PE response teams (PERTs) are recommended to improve timeliness of care.
- In patients with acute PE who require initial parenteral anticoagulant therapy, low-molecular-weight heparin (LMWH) is recommended over unfractionated heparin (UFH).
- In patients with acute PE who are eligible for oral anticoagulation, direct oral anticoagulants (DOACs) are recommended over vitamin K antagonists (VKAs), unless contraindicated, to prevent recurrent venous thromboembolism (VTE) and reduce major bleeding.
- In patients with a first acute PE without a major reversible risk factor and in those with a persistent risk factor, continuing anticoagulation beyond the initial treatment phase (3-6 months) into the extended phase is recommended.
- Patients who have had acute PE should be asked about PE-related symptoms and functional limitations at every visit for at least 1 year to screen for chronic thromboembolic pulmonary disease (CTEPD) or other causes of dyspnea and functional limitation.
