PRECISE-DAPT Score Calculator
The PRECISE-DAPT Score is a clinical risk score used after PCI (coronary stenting) to estimate a patient’s out-of-hospital bleeding risk while on dual antiplatelet therapy (DAPT). It helps clinicians decide whether a shorter or longer DAPT duration is more appropriate by balancing bleeding risk against ischemic benefit.
It is calculated from 5 variables:
- Age
- Hemoglobin
- White blood cell count
- Creatinine clearance
- History of prior spontaneous bleeding
In routine use, a score of 25 or higher is generally considered high bleeding risk. Patients in that range are often considered for shorter DAPT, while lower scores suggest relatively lower bleeding risk.
A simple way to think about it:
- Lower score = bleeding risk is lower
- Higher score = bleeding risk is higher, so prolonged DAPT may be less favorable
It is a decision-support tool, not a stand-alone rule. Doctors still interpret it together with things like the reason for PCI, stent complexity, prior heart attack risk, kidney function, anemia, and the patient’s overall situation.
