HelixTalk #196 - Stretching the Stroke Clock to 2026: A Brief Review of the 2026 Acute Ischemic Stroke Guidelines

Date posted: March 18, 2026, 1:53 pm

In this episode, we review key updates from the 2026 AHA/ASA Guideline for the Early Management of Patients With Acute Ischemic Stroke, including changes to IV thrombolysis, antiplatelet therapy, endovascular treatment, blood pressure goals, and glycemic goals.

Key Concepts

  1. Tenecteplase (TNKase) is now equally preferred to alteplase (Activase) by the 2026 AHA/ASA guidelines. Tenecteplase has several advantages related to administration and the risk of medication errors.
  2. IV thrombolysis can be given in selected patients up to 9 hours after stroke symptom onset depending on brain imaging findings. Patients with symptom onset less than 4.5 hours are still eligible for IV thrombolysis regardless of brain imaging findings.
  3. IV thrombolysis should not be given for mild, non-disabling stroke symptoms. A “non-disabling” stroke means the symptoms do not impair activities of daily living or ability to return to work.
  4. The criteria for dual antiplatelet therapy (DAPT) has been updated. DAPT can be given for NIHSS of 4 or 5 (not just 3 or less) and can be started up to 72 hours after stroke onset (not just within 24 hours).
