Episode Details

CardioNerds (Dr. Billy-Joe Mullinax, Dr. Dinu Balanescu, and Dr. Jane Ehret) discuss risk stratification in acute pulmonary embolism with Dr. Stavros Konstantinides, Chair of the 2019 ESC Pulmonary Embolism Guidelines. Using a real-world case, this episode explores how modern PE care has moved beyond “massive” and “submassive” labels toward a dynamic, physiology-based approach. The discussion highlights the limitations of static risk scores, the importance of right ventricular dysfunction and biomarkers, and why normotension does not imply stability. Special emphasis is placed on intermediate-high risk PE, early identification of impending hemodynamic collapse, and the role of lactate, serial reassessment, and PERT teams in guiding escalation of care. Audio editing by CardioNerds intern, Joshua Khorsandi.
The 2026 American multi-society PE guidelines were published after this episode was recorded.

Dr. Dinu Balanescu and Dr. Billy-Joe Mullinax are Co-chairs for the CardioNerds PE Series, developed in collaboration with the PERT Consortium.
