Pdf Summary

The 2026 AHA/ACC/ACCP/ACEP/CHEST/SCAI/SHM/SIR/SVM/SVN guideline provides a comprehensive, evidence-based approach to evaluating, managing, and following adults (≥18 years) with acute pulmonary embolism (PE), spanning symptom onset through post-discharge care. A central innovation is the AHA/ACC <strong>Acute Pulmonary Embolism Clinical Categories (A–E)</strong>, designed to improve severity classification, prognosis, and treatment selection by integrating clinical severity scores, hemodynamics, respiratory status, biomarkers, and right ventricular (RV) imaging. Category A covers incidental/asymptomatic PE; B symptomatic low-risk; C symptomatic with elevated severity scores (with/without biomarker/RV abnormalities); D incipient cardiopulmonary failure (including “normotensive shock” concepts); and E cardiopulmonary failure with persistent hypotension, refractory shock, or arrest. A respiratory modifier (“R”) captures prominent hypoxemia/ventilatory support needs.

For diagnosis, the guideline emphasizes structured pretest probability assessment (e.g., Wells, Geneva, PERC) and <strong>D-dimer strategies</strong> (age-adjusted thresholds; YEARS, including pregnancy-adapted YEARS) to safely reduce unnecessary imaging. When imaging is indicated, <strong>CT pulmonary angiography (CTPA)</strong> is preferred over V/Q scanning for confirmation; V/Q SPECT is favored over planar V/Q when used. Echocardiography is <strong>not</strong> recommended to diagnose PE but is important for RV risk stratification and should include standardized RV metrics; CTPA reports should include numeric RV/LV ratio.

Management centers on prompt <strong>anticoagulation</strong>: LMWH is recommended over UFH when parenteral therapy is needed, and DOACs are recommended over warfarin when eligible. Outpatient treatment or early discharge is reasonable for Category A/B patients with appropriate decision tools and reliable follow-up. <strong>PERT teams</strong> are recommended to improve timeliness and coordination, especially for higher-risk PE. Advanced therapies (systemic thrombolysis, catheter-directed thrombolysis, mechanical thrombectomy, surgical embolectomy, ECMO) are mainly reserved for the highest-risk categories, balancing benefit against bleeding risk. IVC filters are limited to patients who cannot receive anticoagulation, with retrievable filters and structured retrieval plans emphasized.

Follow-up includes early post-discharge contact (within ~1 week), reassessment by ≤3 months for anticoagulation duration, and symptom screening for at least 1 year to detect chronic thromboembolic pulmonary disease and other sequelae.
