DAPT Score: Evaluating Benefit-Risk of Dual Antiplatelet Therapy, Lecture notes of Cardiology
The dapt score is a tool designed to help clinicians determine whether a patient is more likely to benefit or harm from continued dual antiplatelet therapy (dapt) beyond one year. By accounting for the risks of ischemia and bleeding, this score can guide decisions on treatment duration. A high dapt score (≥2) indicates a favorable benefit-risk ratio, with an nnt to prevent ischemia of 34 and an nnh to cause bleeding of 272. A low dapt score (<2) suggests an unfavorable benefit-risk ratio, with an nnt to prevent ischemia of 153 and an nnh to cause bleeding of 64. Additionally, the precise-dapt score, a simple five-item risk score, can predict out-of-hospital bleeding during dapt and support clinical decision-making in the context of a comprehensive evaluation process.

DAPT SCORE
(THE DUAL ANTI-PLATELET SCORE)
A score of ≥2 is associated with a favorable benefit/risk ratio for prolonged
DAPT while a score of <2 is associated with an unfavorable benefit/risk
ratio.
4 Among patients who have not had a major ischemic or bleeding event within the first year after PCI: The DAPT Score identified patients for whom ischemic benefits outweighed bleeding risks, and patients for whom bleeding risks outweighed ischemic benefits. DAPT Score may help clinicians decide who should, and who should not be treated with extended DAPT High DAPT Score ≥ 2 NNT to prevent ischemia = 34 NNH to cause bleeding = 272 Low DAPT Score (< 2) NNT to prevent ischemia = 153 NNH to cause bleeding = 64
