Summary
Enter five clinical variables to get the PRECISE-DAPT score and a recommendation on short (3–6 month) versus standard/long (12–24 month) DAPT duration after PCI.
How it works
- Enter the five required clinical variables: creatinine clearance, hemoglobin, white blood cell count, age, and prior spontaneous bleeding history.
- The tool applies the validated PRECISE-DAPT formula, weighting each variable according to published coefficients.
- Scores range from 0 to 100; a score ≥25 indicates high bleeding risk.
- High bleeding risk (≥25) supports a shorter DAPT duration of 3–6 months after PCI.
- Low bleeding risk (<25) supports standard (12 months) or extended DAPT to reduce ischemic events.
- Always apply clinical judgment and discuss findings with the patient.
Use cases
- Guide DAPT duration decisions in patients undergoing elective or urgent PCI.
- Identify high-bleeding-risk patients who may benefit from abbreviated DAPT.
- Support shared decision-making between clinician and patient after stent implantation.
- Complement ischemic risk scores (e.g., DAPT score) for a balanced benefit-risk assessment.
- Document bleeding risk stratification in clinical notes.
- Educational tool for cardiology trainees learning DAPT management.
