What is the SAMe-TT2R2 score?
The SAMe-TT2R2 score is a clinical score based on routine clinical parameters, which can be used to identify patients who may be able to attain good anticoagulation control (eg, TTR 65%) with a VKA. It has been assessed in 15 exclusively AF cohorts, with c-statistics ranging from 0.54 to 0.82. The score has been shown to be able to dichotomize the patients likely to do well on VKA, compared with those (score > 2) more likely to achieve poor TTR, in multi-ethnic non-white Singaporean population.
