CHA₂DS₂-VASc Score for Atrial Fibrillation Stroke Risk flow

Introduction

CHA2DS2-VASc score (Birmingham 2009) was developed after identifying additional stroke risk factors in patients with atrial fibrillation.

The CHA2DS2-VASc score is one of several risk stratification schema that can help determine the 1 year risk of a TE event in a non-anticoagulated patient with non-valvular AF. The CHA2DS2-VASc score, among other risk stratification schema, can be used to provide an idea of a patient’s risk for TE event.

Calculation

The score is calculated by simply summing the points of all 7 items.

The CHA₂DS₂-VASc Score for Atrial Fibrillation Stroke Risk flow contains the CHA₂DS₂-VASc Score for Atrial Fibrillation Stroke Risk questionnaire and associated calculation. After form submission, the CHA₂DS₂-VASc Score for Atrial Fibrillation Stroke Risk calculation is executed automatically. It's easy to extend this flow with conditional logic based on the interpretation of the CHA₂DS₂-VASc Score for Atrial Fibrillation Stroke Risk calculation.
