For PRECISE-DAPT scores, use a nomogram: note the values for each of the five clinical parameters and draw a vertical line to the Scale Score axis to determine the score for each clinical parameter. Then add the scores for each clinical measure to determine the total score.

NB! Time of use of this score – during stenting of the coronary arteries.

Depending on the obtained results, and the calculated data decision can be made on short-term DAPT (3-6 months) or standard/long-term DAPT (12-24 months), taking into account the presence of the risks of bleeding.

The range of values is from 0 to 100 points.
