How to Use the PRECISE-DAPT Score Calculator
- Enter Age in years.
- Enter Creatinine clearance (CrCl) in mL/min.
- Enter Hemoglobin in g/dL.
- Enter White blood cell count in ×10³/µL.
- Enter Prior spontaneous bleed requiring hospitalization/transfusion.
- Click Calculate to see your result and interpretation.
Formula & Version
This calculator uses formula version 1.0, last reviewed September 2026.
Clinical Considerations & Limitations
- The original PRECISE-DAPT score is derived from a nomogram; this implementation approximates it with banded points for age, CrCl, hemoglobin, and WBC rather than reproducing the exact published curve, and should be checked against the official calculator before clinical use.
- The ≥ 25 high-bleeding-risk threshold (favoring shorter DAPT duration) is the well-established part of this score and is used here as published.
