Amlan Datta: When Do We Actually Use Dual Antiplatelet Therapy in Stroke Prevention?

Amlan Datta, Assistant Professor at Jagannath Gupta Institute of Medical Sciences and Hospital in North Kolkata and Consultant Neurologist at Narayana Health and Zenith Super Specialist Hospital, shared a post on LinkedIn:

”When do we actually use Dual Anti-Platelet Therapy (DAPT) in stroke prevention?

The guidelines have evolved significantly, moving beyond simple aspirin use for many patients. Here’s a concise breakdown of the current AHA/ASA recommendations — essential for any physician managing these cases.

Minor Stroke / High-risk TIA: If a patient has a minor stroke (NIHSS ≤ 3) or a high-risk TIA (ABCD² ≥ 4), the evidence from the CHANCE and POINT trials supports starting DAPT within 24 hours. This aggressive approach continues for 21 days, which is the highest-risk period for recurrence.
After Carotid Intervention (CAS): Following carotid artery stenting, DAPT is mandatory to prevent early stent thrombosis while the vessel heals. According to CREST protocols, this duration is typically 30 days.
Intracranial Large-Vessel Stenosis: For symptomatic 70-99% stenosis of a major intracranial artery, the SAMMPRIS trial indicates that aggressive medical therapy is effective. Here, DAPT is recommended for a full 90 days.

The key takeaway? Timing and duration are paramount, always balancing the significant reduction in recurrent ischemic events against the increased bleeding risk.”
