Overview
The DAPT score is a clinical prediction score assessing ischemic and bleeding risks at 12 to 30 months following percutaneous coronary intervention (PCI) to inform the duration of dual antiplatelet therapy (DAPT). The score was derived from the DAPT study (ClinicalTrials.gov: NCT00977938) and initially validated in the PROTECT trial (ClinicalTrials.gov: NCT00476957).
DAPT Score
The DAPT score is a simplified clinical prediction score designed to assess the benefit-risk tradeoff between ischemia reduction (myocardial infarction or stent thrombosis) and bleeding increase (moderate or severe hemorrhage) associated with continued thienopyridine plus aspirin versus aspirin alone beyond one year after PCI based on 11,648 patients enrolled in the DAPT study (derivation cohort) and 8,136 patients enrolled in the PROTECT trial (validation cohort).[1]

Shown below is the calculator for the DAPT score (check all the boxes that apply):
Interpretation
- Score ≥2 (high score): Favorable benefit-to-risk for prolonged DAPT, with greater ischemic reduction (2.7% for DAPT vs 5.7% for aspirin alone; difference, −3.0% [95% CI, −4.1% to −2.0%]) and smaller bleeding increase (1.8% vs 1.4%; difference, 0.4% [95% CI, −0.3% to 1.0%])
- Score <2 (low score): Unfavorable benefit-to-risk for prolonged DAPT, with smaller ischemic reduction (1.7% for DAPT vs 2.3% for aspirin alone; difference, −0.7% [95% CI, −1.4% to 0.1%]) but greater bleeding increase (3.0% vs 1.4%; difference, 1.5% [95% CI, 0.8% to 2.3%])
