PRECISE-DAPT, a new bleeding risk calculator available online and as an application, uses age, creatinine clearance, white-blood-cell count, Hb, and history of bleeding to predict out-of-hospital bleeding in patients treated with dual antiplatelet therapy (DAPT).
Why this matters
A standardized bleeding risk-assessment tool would help clinicians determine the most appropriate DAPT treatment duration for patients after coronary stent implantation via percutaneous coronary intervention (PCI).
14,590 patients pooled from 8 multicenter, randomized trials who underwent PCI for coronary stent implantation with subsequent DAPT.
External validation with patients from PLATO trial (n=8595) and BernPCI Registry (n=6172).
Bleeding risk predictors with P<.10 were identified from randomized trials (age, creatinine clearance, Hb, white-blood-cell count at baseline, and previous spontaneous bleeding).
