total score =
= SUM(points for all 9 parameters)
Interpretation:
• minimum score: -2
• maximum score: 10
• A score < 2 is associated with greater risk of bleeding with a similar risk for ischemia.
• A score >= 2 is associated with greater ischemic benefit (lower AMI or stent thrombosis).
• A patient with a high DAPT score may benefit from prolonged thienopyridine.
