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
- Enter the five required clinical variables: creatinine clearance, hemoglobin, white blood cell count, age, and prior spontaneous bleeding history.
- The tool assigns points from the published PRECISE-DAPT nomogram and sums them.
- Scores range from 0 to 100; a score ≥25 indicates high bleeding risk.
- The ≥25 threshold must be interpreted together with ischemic risk and current clinical guidance.
- 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.
