ATRIA_stroke_risk_score v.1

ATRIA (anticoagulation and risk factors in atrial fibrillation) stroke risk score is used to determine the risk of stroke in patients with atrial fibrillation. It is the sum of points assigned for the presence (or absence) of certain risk factors: previous stroke, age, sex, comorbidities (diabetes, congestive heart failure, hypertension), proteinuria, and eGFR < 45ml/min (or end stage renal disease) in the patient. The ATRIA stroke risk score takes a value between 0 - 15, and it is from this score that ATRIA stroke risk is predicted. A score between 0 - 5 predicts a risk of ischaemic stroke/TE less than 1%; a score of 6 predicts 1 - <2% risk; and a score >6 predicts ≥2% risk.

Calculates ATRIA stroke risk score based on the following assessed variables: prior stroke, age, sex, comorbidities (diabetes mellitus, congestive heart failure, hypertension), proteinuria, and eGFR <45ml/min (or ESRD - end stage renal disease). ATRIA stroke risk score has been validated as performing better than the CHADS2 and CHA2DS2-VASc risk models and provides more accurate and reliable stroke risk/thromboembolism prediction, as well as guides optimal anticoagulation decision-making, in individuals with atrial fibrillation.

To calculate ATRIA stroke risk score based on: - presence of diabetes mellitus, congestive heart failure, hypertension, proteinuria (urinary albumin >=30 mg/dl OR urinary abumin:cratinine ratio >=30 mg/g), eGFR < 45ml/min (or ESRD) = 1 point each, and 0 if absent; - female sex = 1 point, and 0 if male; - age <65 years (with no prior stroke = 0, with prior stroke = 8 points), 65-74 years (with no prior stroke = 3, with prior stroke = 7 points), 75-84 years (with no prior stroke = 5, with prior stroke = 7 points), >=85 years (with no prior stroke = 6, with prior stroke = 9 points). The ATRIA stroke risk score is further used in evaluating the 1-year risk of stroke or other thromboembolic event.

Do not use this calculator if the individual does not have atrial fibrillation.
