What is the SAMe-TT2R2 score?
The SAMe-TT2R2 score is a predictive tool used to forecast good or poor anticoagulation control in patients with atrial fibrillation (AF). It has been assessed in 15 exclusive AF cohorts and has c-statistics ranging from 0.54 to 0.85. The score is able to dichotomize patients likely to do well on VKA (score 0-2) versus those more likely to achieve poor TTR (score >2). In some healthcare systems, it can be used to aid decision-making when determining the most appropriate OAC for the patient.
