“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).
