Summary

The PRECISE-DAPT score uses five clinical variables — creatinine clearance, hemoglobin, white blood cell count, age, and prior spontaneous bleeding — to stratify out-of-hospital bleeding risk after PCI. Scores range from 0 to 100, and ≥25 is the published high-risk threshold. The score must be combined with ischemic risk and current clinical guidance; it does not prescribe DAPT duration.

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 assigns points from the published PRECISE-DAPT nomogram and sums them.
  3. Scores range from 0 to 100; a score ≥25 indicates high bleeding risk.
  4. The ≥25 threshold must be interpreted together with ischemic risk and current clinical guidance.
  5. 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.
