Episode Details

We are unbelievably excited this week to be reviewing the hot-off-the-presses 2026 Multi-Society (AHA/ACC/ACCP/ACEP/CHEST/SCAI/SHM/SIR/SVM/SVN) Pulmonary Embolism Guidelines with lead author Dr. Mark A. Creager. We will talk about key updates in these guidelines compared to prior practice, including the new risk classification model, and provide an overview from diagnosis to follow-up. Given the clinical importance and prevalence of pulmonary embolism, these guidelines are certainly going to shape practice going forward, so this episode is a can’t miss!

Key Learning Points

Why these guidelines matter:

This is the first joint AHA/ACC clinical practice guideline specifically on acute PE, bringing together a truly multidisciplinary writing committee (cardiology, pulmonology, hematology, emergency medicine, interventional radiology, surgery, and others). Prior guidelines existed from individual societies, but nothing this comprehensive had been updated in roughly five to six years.

New PE clinical categories (A through E):

One of the most impactful changes is replacing the old “massive/submassive” and “low/intermediate/high risk” labels with five categories that form a severity continuum. Category A is subclinical (incidental PE found on imaging in asymptomatic patients). Category B covers symptomatic but low-severity patients. Category C is where much of the clinical complexity lives — symptomatic, hemodynamically stable patient
