What is the 2026 AHA/ASA Acute Ischemic Stroke Guideline?
The 2026 AHA/ASA Guideline for the Early Management of Patients With Acute Ischemic Stroke provides comprehensive, evidence-based recommendations for stroke care from prehospital evaluation through acute treatment and early in-hospital management. It replaces previous guidelines with updated evidence on thrombolytic choice, endovascular thrombectomy eligibility, and new pediatric recommendations.
Introduction
Every year, more than 600,000 individuals in the United States experience a first ischemic stroke, making it one of the most critical conditions encountered in emergency and neurological medicine.
The 2026 Guideline for the Early Management of Patients With Acute Ischemic Stroke represents the most current and comprehensive evidence available in acute ischemic stroke care, replacing the 2018 guidelines and the 2019 update.
This authoritative document from the American Heart Association and American Stroke Association serves as an essential resource for healthcare professionals dedicated to improving stroke outcomes.
This guideline addresses the full continuum of care—from prehospital evaluation through acute treatment and early in-hospital management of complications.
It incorporates significant advances in stroke medicine, including new evidence on thrombolytic choice and eligibility, eligibility criteria for endovascular thrombectomy, and management of hyperglycemia and dysphagia. For the first time, it includes focused recommendations for the pediatric population.
The intended audience includes prehospital care professionals, physicians, allied health professionals, and hospital administrators, making it an indispensable reference across the stroke care continuum.

What This Book Covers
The 2026 AHA/ASA Acute Ischemic Stroke Guideline provides comprehensive coverage of the full spectrum of acute ischemic stroke management. The guideline is organized into six major sections that follow the patient journey from symptom onset through hospitalization.
- Stroke Systems of Care and Prehospital Management: This section addresses population-level stroke awareness, emergency medical services systems, prehospital assessment and management, EMS destination management, and the role of mobile stroke units. It emphasizes the importance of coordinated regional stroke systems to increase access to time-sensitive therapies and recommends that hospitals participate in accountable stroke systems of care.
- Emergency Evaluation and Treatment: This section covers stroke scales, initial vascular and multimodal imaging approaches, and other diagnostic tests. It provides detailed recommendations on the use of the NIH Stroke Scale, imaging protocols for thrombolysis and thrombectomy eligibility, and the role of ECG and troponin testing in the acute evaluation.
- General Supportive Early Management: This comprehensive section includes recommendations on airway and breathing management, head positioning, blood pressure management, temperature management, blood glucose management, intravenous thrombolytics, endovascular thrombectomy, antiplatelet treatment, anticoagulants, volume expansion, vasodilators, hemodynamic augmentation, neuroprotective agents, and emergency carotid endarterectomy.
- In-Hospital Management of AIS – General Supportive Care: This section covers stroke units, dysphagia management, nutrition, deep vein thrombosis prophylaxis, depression screening and treatment, other in-hospital management considerations, and rehabilitation.
- In-Hospital Management of AIS—Treatment of Acute Complications: This section addresses brain swelling (general recommendations, medical management, and surgical management for both supratentorial and cerebellar infarction) and seizures.
Key Features
- Evidence-Based Recommendations: All recommendations are graded with Class of Recommendation and Level of Evidence, providing clear guidance on the strength and quality of supporting evidence.
- Pediatric Focus: For the first time, the guideline includes comprehensive recommendations for pediatric patients with acute ischemic stroke, addressing imaging, thrombolysis, and endovascular thrombectomy in children.
- Updated Thrombolytic Guidance: New recommendations endorse the use of either alteplase or tenecteplase in the 4.5-hour treatment window, with tenecteplase offering practical advantages as a single bolus injection.
- Expanded Endovascular Thrombectomy Criteria: Recent evidence supports expanding EVT to populations previously considered ineligible, including patients with larger ischemic core strokes.
- Posterior Circulation Stroke Recommendations: Strong recommendations for EVT in patients with basilar artery occlusion presenting within 24 hours of symptom onset.
- Blood Pressure Management Updates: New evidence guides BP management after IVT and EVT, with recommendations against intensive systolic BP reduction to <140 mm Hg even with complete reperfusion.
- Mobile Stroke Unit Guidance: Updated recommendations support the use of MSUs over conventional EMS where available.
- Practical Management Tables: Includes tables for thrombolysis dosing, management of symptomatic intracranial bleeding, and management of orolingual angioedema.
