The ATRIA stroke risk score is a tool used to assess an individual's risk of experiencing a stroke. This assessment involves several personal health factors that contribute to the overall risk, and the score reflects the cumulative impact of these factors.

To calculate the score, the tool assigns points to various inputs based on predefined risk categories:

- Age:
  - Under 65 years is assigned 0 points.
  - 65 to 74 years is assigned 3 points.
  - 75 to 84 years is assigned 5 points.
  - 85 years and older is assigned 6 points.

- Gender:
  - Female is assigned 1 point.
  - Male is assigned 0 points.

- History of diabetes mellitus:
  - Yes is assigned 1 point.
  - No is assigned 0 points.

- History of chronic heart failure:
  - Yes is assigned 1 point.
  - No is assigned 0 points.

- History of hypertension:
  - Yes is assigned 1 point.
  - No is assigned 0 points.

- Proteinuria (presence of excess protein in urine):
  - Yes is assigned 1 point.
  - No is assigned 0 points.

- eGFR < 45 or end-stage renal disease:
  - Yes is assigned 1 point.
  - No is assigned 0 points.

The total score is calculated by adding up the points from each category. This total score, ranging from 0 to 12, helps classify the stroke risk level:

- Scores of 0 to 5 are interpreted as a low risk of stroke.
- A score of 6 indicates a moderate risk of stroke.
- Scores of 7 or more signify a high risk of stroke.

This comprehensive evaluation enables individuals and healthcare providers to understand the relative risk associated with various health conditions and demographic factors, empowering informed discussions around stroke prevention.

The Anticoagulation and Risk Factors in Atrial Fibrillation (ATRIA) stroke risk score is a clinical tool designed to stratify the risk of stroke in patients with atrial fibrillation. The primary components of the ATRIA score include age, gender, history of diabetes mellitus, history of chronic heart failure, history of hypertension, presence of proteinuria, and estimated glomerular filtration rate (eGFR) < 45 or end-stage renal disease. Age is divided into four categories, each associated with a different risk level. The presence of each medical condition or risk factor contributes to the overall score, which is used to predict the patient's risk of stroke. The ATRIA score is particularly useful in guiding therapeutic decisions, such as the initiation of anticoagulation therapy.
