The CHA2DS2-VASc Score Calculator is a tool used in the assessment of stroke risk in patients with atrial fibrillation (AF). It helps clinicians evaluate the risk of stroke and determine the need for anticoagulant therapy.
The acronym “CHA2DS2-VASc” stands for:
- Congestive Heart Failure (CHF)
- Hypertension
- Age (≥75 years = 2 points, 65–74 years = 1 point)
- Diabetes Mellitus
- Stroke or TIA (Transient Ischemic Attack)
- Vascular Disease (e.g., prior myocardial infarction, peripheral artery disease)
- Age (65–74 years)
- Sex category (Female)
Each factor is assigned a certain number of points, and the total score is used to estimate the risk of stroke. The higher the score, the greater the risk of stroke. The calculator assists healthcare providers in making decisions regarding anticoagulation therapy for stroke prevention in patients with AF.
The CHA2DS2-VASc Score Calculator typically involves input fields for each of these risk factors, allowing healthcare professionals to input patient data and calculate the corresponding CHA2DS2-VASc score. The result usually includes the total score and an assessment of stroke risk based on the score.
