What is the SAMe-TT2R2 score?
The SAMe-TT2R2 score is a predictive tool used to forecast good or poor anticoagulation control for patients with atrial fibrillation (AF). It has been assessed in 15 exclusively AF cohorts and has been reported to have c-statistics ranging from 0.54 to 0.87. The score has been tested in some VTE populations, where it similarly identifies patients likely to achieve a good TTR. The score is used to aid decision-making to help identify patients likely to do well on VKA (vitamin K antagonist) therapy. Patients with a score of 0-2 are likely to achieve a good TTR.
