Overview

The DAPT score is a clinical prediction score assessing late ischemic and bleeding risks 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 risk score derived from the DAPT (Dual Antiplatelet Therapy) Trial. It is a validated risk assessment tool designed to assess the risk-benefit of the dual antiplatelet therapy following PCI and insertion of a drug-eluting stent.[1][2][3][4][5][6]

DAPT Score Calculator

Shown below is the calculator for DAPT score (check all the boxes that apply):

DAPT Score Calculator
Variable Score
Age ≥ 75 years old -2
65-74 years old -1
< 65 years old 0
Cigarette smoking 1
Diabetes mellitus 1
Prior MI or PCI 1
MI at presentation 1
Paclitaxel-eluting stent 1
Stent diameter < 3 mm 1
CHF or LVEF < 30% 2
Vein graft stent 2
DAPT Score:
Interpretation:

Interpretation

  • Score <2: Higher risk of bleeding and a smaller reduction in ischemia, associated with an unfavorable benefit-to-risk ratio for prolonged DAPT
  • Score ≥2: Smaller risk of bleeding and a greater reduction in ischemia, associated with a favorable benefit-to-risk ratio for prolonged DAPT
