Ahmed Magdi Omar: Key Takeaways From the Latest 2026 Guidelines on Antiplatelet Therapy in AIS

Ahmed Magdi Omar, Cardiologist at MantraCare, Cardiovascular Specialist at Damas GIT and Cardio-vascular Center, shared a post on LinkedIn:

“Antiplatelet Therapy in Acute Ischemic Stroke (AIS)

From the Latest 2026 Guidelines

8 Key Takeaways

1. Dual Antiplatelet Therapy (DAPT)

(For non-cardioembolic patients Not eligible for revascularization)

Within <24 hours of symptom onset

  • Aspirin and Clopidogrel for 21 days, then single antiplatelet therapy (SAPT)

Indications:

  • Minor AIS (NIHSS ≤3) or high-risk TIA (ABCD2 ≥4) (Class 1)
  • NIHSS 4–5 with presumed atherosclerotic cause (≥50% stenosis or imaging evidence) (Class 2a)

Aspirin and Ticagrelor for 30 days

Indications:

  • Minor AIS (NIHSS ≤5) or high-risk TIA (ABCD2 ≥6 or ≥50% symptomatic stenosis) (Class 2b)

24–72 hours after symptom onset

Aspirin and Clopidogrel for 21 days, then SAPT

Indications:

  • Minor AIS (NIHSS ≤5) or high-risk TIA (ABCD2 ≥4)
  • With presumed atherosclerotic cause (Class 2a)

2. Aspirin Timing

  • Start within 48 hours after stroke onset (Class 1)

3. Triple Antiplatelet Therapy

  • Not recommended (Aspirin and Clopidogrel and Dipyridamole)
  • Due to increased bleeding risk (Class 3: Harm)

4. Stroke Occurring While on Aspirin

  • Increasing aspirin dose or switching antiplatelet
  • No clear benefit (Class 2b)

5. Ticagrelor vs Aspirin

  • In minor AIS (NIHSS ≤3) or high-risk TIA (ABCD2 ≥4)
  • Ticagrelor is not superior to aspirin (Class 3: No benefit)

6. Stroke with Atrial Fibrillation on Anticoagulation

  • Do NOT routinely add antiplatelet
  • Increased bleeding risk (Class 3: Harm)

7. Antiplatelet Within 24 Hours After IV Thrombolysis (IVT)

  • Risk is uncertain
  • May consider in selected cases with strong indication (Class 2b)

8. Patients on Antiplatelet Who Need IV Thrombolysis

  • Still recommend IVT
  • Improves functional outcomes
  • Benefit outweighs increased intracranial hemorrhage risk (Class 1).
