ATRIA Stroke-Risk Score in Atrial Fibrillation Calculator

Sum of 7 weighted predictors (max 15).

Compute the ATRIA stroke-risk score for atrial-fibrillation patients (Singer 2013). Sum of 7 weighted predictors. Without prior stroke: ≤ 5 = low (< 1 % / yr), 6 = intermediate (~1–2 %), 7-15 = high (> 2 %). With prior stroke, age points are higher and overall risk is elevated; this calculator implements the published point system.
