DAPT score
Also written as: DAPT — Dual AntiPlatelet Therapy
A risk prediction tool for determining optimal dual antiplatelet therapy duration.
Full Definition
The DAPT score is a validated clinical decision tool that predicts the relative benefit and harm of extended dual antiplatelet therapy beyond one year after percutaneous coronary intervention. The score incorporates nine clinical and angiographic variables including age, cigarette smoking, diabetes, myocardial infarction at presentation, prior PCI or MI, paclitaxel-eluting stent, stent diameter, congestive heart failure, and saphenous vein graft. Scores ≥2 suggest potential benefit from extended DAPT, while scores <2 suggest potential harm.
Usage
Usage note: DAPT should be capitalized when referring to the specific score. Spell out 'dual antiplatelet therapy' on first use.
