What is the purpose of the SAMe-TT2R2 score?
The SAMe-TT2R2 score is a tool used to assess the quality of anticoagulation therapy in patients with atrial fibrillation. It is used to predict the mean time in the therapeutic International Normalized Ratio (INR) range, as well as predict the risk of poor-quality anticoagulation, stroke, clinically relevant bleeding, and mortality in these patients. It is based on a combination of patient-specific factors such as age, gender, body mass index, renal function, presence of congestive heart failure or chronic obstructive pulmonary disease, and concomitant medications.
