The core of today’s playbook is the new 2026 AHA/ACC Clinical Categories—it’s an A through E system that moves the focus from 'how big is the clot?' to 'how is the patient actually doing?'

The 2026 AHA/ACC clinical categories represent a shift away from older labels like 'massive' or 'submassive' pulmonary embolism. This new A through E system provides a more precise classification for patients. By utilizing this playbook, clinicians can move toward a more disciplined approach to risk stratification, ensuring that treatment decisions are based on a standardized and holistic assessment of the patient's specific clinical status.
The A-E playbook improves PE risk stratification by removing the guesswork associated with vague terminology. It requires clinicians to evaluate a patient's hemodynamics, respiratory status, and cardiac biomarkers simultaneously. This comprehensive method helps medical professionals in the ER, ICU, and primary care settings distinguish between incidental clots and high-risk cases where the heart is at risk of failing, ultimately improving patient outcomes.
The classification is changing because traditional labels are no longer sufficient for modern clinical needs. With testing becoming more sensitive, more pulmonary embolisms are being detected than ever before. Because one in five high-risk patients die, the new AHA/ACC clinical categories were developed to provide a more precise framework. This helps prevent the over-treatment of minor clots while ensuring life-saving interventions are prioritized for critical cases.
