What is the SAMe-TT2R2 score?
The SAMe-TT2R2 score is a tool used to predict anticoagulation control in individuals taking vitamin K antagonists, such as warfarin. It is calculated by taking into account six different patient characteristics: sex, age, medical history, treatment, tobacco use, and race. The score has been found to be useful in predicting time to therapeutic range (TtTR), anticoagulation control, and cardiovascular events in vitamin K antagonists-naive patients with atrial fibrillation.
