DAPT Score
Point Breakdown
Educational use only. This tool does not constitute medical advice. DAPT duration decisions require evaluation by a qualified cardiologist considering individual bleeding history, comorbidities, patient preference, and current guidelines.
Summary
The DAPT Score is a validated clinical tool that helps cardiologists decide whether to extend dual antiplatelet therapy (DAPT) beyond the standard 12 months after coronary stent placement. Scores range from -2 to +10; a score of ≥2 favors prolonged DAPT due to net ischemic benefit, while a score <2 suggests the bleeding risk outweighs the benefit. The score incorporates age, clinical history, procedural variables, and stent type.
How it works
- Enter the patient's age group and select relevant clinical and procedural variables.
- Each variable adds or subtracts points according to the validated DAPT scoring algorithm.
- The tool sums all points to produce a score between -2 and +10.
- A score ≥2 suggests extended DAPT (>12 months) reduces ischemic events outweighing bleeding risk.
- A score <2 suggests extended DAPT increases bleeding risk without sufficient ischemic benefit.
- Review the interpretation and discuss findings with the treating cardiologist.
Use cases
- Assessing whether to continue clopidogrel or prasugrel beyond 12 months post-PCI.
- Estimating the balance of ischemic vs. bleeding risk for individual stent patients.
- Supporting shared decision-making between cardiologist and patient.
- Educational review of DAPT score variables and their clinical weights.
- Cardiology fellow training and clinical reference.
