Key highlights from the 2026 AHA/ACC guideline (the first dedicated US PE guideline, published February 2026):
  1. New 5-category system (A–E) replaces "massive/submassive/low-risk" — more granular, prognosis-driven classification
  2. DOACs are now formally Class I (recommended over VKAs) — first explicit endorsement in a US guideline
  3. PERT activation upgraded to Class I for categories C–E
  4. CDT and mechanical thrombectomy given Class 2a recommendations for Category D (intermediate-high)
  5. Outpatient treatment explicitly endorsed for Category B (low-severity)
  6. VA-ECMO recognized as a bridging strategy in refractory Category E
