DAPT Score for Dual Antiplatelet Therapy Duration

Balances ischaemic benefit vs bleeding risk of prolonged dual antiplatelet therapy (DAPT) after drug-eluting stent (DES) placement. Guides decision to continue or stop DAPT after 12 months.

Score interpretation

Benefit — Continue DAPT Beyond 12 months

→ DAPT Score ≥2: Ischaemic benefit outweighs bleeding risk. Continue DAPT for up to 30 months after DES. Assess bleeding risk (HAS-BLED) in parallel. Use aspirin 75–100 mg + P2Y12 inhibitor (clopidogrel or ticagrelor).

No Benefit / Harm — Stop DAPT at 12 months

→ DAPT Score <2: Bleeding risk outweighs ischaemic benefit. Discontinue P2Y12 inhibitor at 12 months. Continue aspirin monotherapy indefinitely. Consider gastric protection (PPI) if high GI bleeding risk.
