DAPT Score Calculator

Your details

Age >= 75 subtracts 2 points; age 65-74 subtracts 1 point; age < 65 adds 0 points.
years
Active smoker or quit within the past 12 months.
Type 1 or type 2 diabetes requiring medication.
The qualifying PCI was performed for an acute myocardial infarction (STEMI or NSTEMI).
History of any percutaneous coronary intervention or myocardial infarction before the qualifying PCI.
The qualifying PCI used a paclitaxel-eluting (TAXUS) stent rather than a bare-metal or other drug-eluting stent.
At least one stent placed during the qualifying PCI had a diameter smaller than 3 mm.
History of congestive heart failure or a measured left ventricular ejection fraction below 30% at time of PCI.
The qualifying PCI involved stenting of a saphenous vein graft rather than a native coronary artery.
DAPT ScoreAspirin monotherapy favored
0

Total score (-2 to 10). Score >= 2 favors prolonged DAPT; score < 2 favors aspirin alone.

RecommendationAspirin alone is likely preferable; prolonged DAPT may increase bleeding risk without sufficient ischemic benefit.
0 pts
Aspirin preferred<2Prolonged DAPT preferred2+

DAPT Score is +0: aspirin alone is favored.

  • A score below 2 indicates that the bleeding risk from extending DAPT beyond 12 months is likely to exceed the ischemic benefit for this patient profile.
  • In the validation cohort, patients with a DAPT score < 2 who received prolonged DAPT had an increased bleeding rate without a proportional ischemic benefit.

Next stepConsider stopping thienopyridine at or after 12 months. Continue aspirin indefinitely per guideline recommendations. Reassess if the clinical picture changes.
