CHA2DS2-VASc Score Calculator

Assess the risk of stroke in patients with non-valvular atrial fibrillation to guide anticoagulation therapy decisions.

Atrial fibrillation (Afib) significantly increases the risk of blood clots forming in the heart, which can travel to the brain and cause a stroke. The CHA2DS2-VASc score is the clinical standard for quantifying this risk. It looks at various health factors—such as age, high blood pressure, and history of heart failure—to determine if the benefits of blood-thinning medication outweigh the risks of bleeding.

使い方

The calculator assigns 1 or 2 points to different risk factors. Most notably, a history of stroke or being 75 or older counts for 2 points each, while other factors count for 1.

計算式

Sum of risk factors (max 9 points)

計算例

1. **High Risk**: Age 76, Htn, and Diabetes = **Score 4**.
