Comparative features of tools for risk estimation.
| DAPT Score | PRECISE-DAPT Score | |
|---|---|---|
| Risk assessed | Combined bleeding and ischemia | Bleeding |
| Variables | Age (65–74: −1, >75: −2), DM (+1), prior MI/PCI (+1), ACS (+1), stent diameter < 3 mm (+1), LVEF < 30% (+1), Vein graft stent (+2), tobacco use (+1) | Hemoglobin, age, prior bleeding, creatinine clearance |
| Time to use | After 12 months of uneventful DAPT | At the time of coronary stenting |
| Cessation strategies assessed | Standard DAPT vs. L-DAPT (>30 months) | S-DAPT (3–6 months) vs. standard/L-DAPT (12–24 months) |
| Score range (points) | −2 to 10 | 0 to 100 |
| Decision suggested based on score in points | L-DAPT for score ≥ 2 Standard DAPT for score < 2 |
S-DAPT for score ≥ 25 Standard/ L-DAPT < 25 |

DM = diabetes mellitus; MI = myocardial infarction; PCI = percutaneous coronary intervention, ACS = acute coronary syndrome; LVEF = left ventricular ejection fraction.
