What are the limitations of the dapt score?

While the dapt score is highly validated, it should not replace clinical judgment. OpiCalc provides the latest evidence-based limitations for the dapt score to ensure safe bedside use and optimal diagnostic accuracy.

How does the dapt score compare to other Cardiovascular scores?

The dapt score is a gold-standard diagnostic tool. OpiCalc provides side-by-side clinical guidance to help clinicians choose the most specific evidence-based tool for their patient's presentation.

Is the dapt score free to use?

Yes. OpiCalc provides the dapt score completely ad-free and optimized for mobile bedside use, ensuring you can calculate medical risk swiftly and without distraction.

When to Use

Decision-making for the duration of Dual Antiplatelet Therapy (DAPT) after coronary stenting.
Identifying patients who may benefit from extending DAPT beyond 12 months vs. those at high bleeding risk.
Evaluation at the 12-month mark post-PCI.

Scoring Variables

Age ≥ 75 ( −2 ), 65-74 ( −1 ), <65 ( 0 )

Cigarette Smoking

Diabetes Mellitus

MI at Presentation

Prior MI or PCI

Stent Diameter < 3mm

Paclitaxel-eluting Stent

Interpretation

Score < 2

Score ≥ 2

CLINICAL INSIGHT

Practical Pearls

Ischemia vs. Bleeding

The DAPT score is a "trade-off" tool. A high score suggests that the risk of stent thrombosis or recurrent MI is high enough to justify the increased bleeding risk of prolonged dual antiplatelet therapy.
