ATRIA Stroke Risk Score: Explanation and Clinical Context The ATRIA Stroke Risk Score is a validated clinical tool to predict the risk of ischemic stroke in patients with atrial fibrillation. It uses common patient characteristics including age, sex, history of diabetes mellitus, heart failure, hypertension, and prior stroke/TIA.
Scores are calculated by assigning points to each risk factor, resulting in a total score that categorizes patients into low, moderate, or high stroke risk.
This tool supports clinicians in risk stratification and guides decisions regarding anticoagulation therapy in atrial fibrillation patients.
