Total Score: 0
Risk Level: Low

Source of Data and Methodology

The calculations are based on the CHA2DS2-VASc scoring system, as outlined in the 2010 European Society of Cardiology guidelines. View source. All calculations are based rigorously on the formulas and data provided by this source.

The Formula Explained

CHA2DS2-VASc = C + H + A2 + D + S2 + V + A + Sc

Glossary of Variables

Practical Example: A Step-by-Step Guide

Consider a 72-year-old patient with a history of hypertension and diabetes. Their CHA2DS2-VASc score is calculated as follows: Age (2) + Hypertension (1) + Diabetes (1) = 4.

Frequently Asked Questions (FAQ)

What is the CHA2DS2-VASc score?

The CHA2DS2-VASc score is a clinical prediction rule for estimating the risk of stroke in patients with atrial fibrillation.

How do I use the CHA2DS2-VASc calculator?

Input the relevant clinical data into the calculator to determine the stroke risk score.

What does a high CHA2DS2-VASc score mean?

A higher score indicates a greater risk of stroke, which may require medical intervention.
