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

  1. Enter the five required clinical variables: creatinine clearance, hemoglobin, white blood cell count, age, and prior spontaneous bleeding history.
  2. The tool applies the validated PRECISE-DAPT formula, weighting each variable according to published coefficients.
  3. Scores range from 0 to 100; a score ≥25 indicates high bleeding risk.
  4. High bleeding risk (≥25) supports a shorter DAPT duration of 3–6 months after PCI.
  5. Low bleeding risk (<25) supports standard (12 months) or extended DAPT to reduce ischemic events.
  6. 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.
