Interpretation

  • Score <2: Higher risk of bleeding and a smaller reduction in ischemia, associated with an unfavorable benefit-to-risk ratio for prolonged DAPT
  • Score ≥2: Smaller risk of bleeding and a greater reduction in ischemia, associated with a favorable benefit-to-risk ratio for prolonged DAPT
