Chadsvasc Score Calculator

Atrial fibrillation (AF) is a common heart rhythm disorder that increases the risk of stroke. To manage this risk, healthcare professionals use the CHA2DS2-VASc Score, a standardized scoring system that evaluates a patient’s likelihood of stroke based on several clinical risk factors. The CHA2DS2-VASc Score Calculator simplifies this process, providing quick and accurate results to guide treatment decisions.

This tool is particularly useful for cardiologists, general practitioners, and even patients seeking to understand their stroke risk. By using this calculator, you can determine whether anticoagulant therapy or lifestyle adjustments are needed to reduce stroke risk.

What Is the CHA2DS2-VASc Score Calculator?

The CHA2DS2-VASc Score Calculator is an interactive tool that evaluates stroke risk in patients with atrial fibrillation. It assigns points to various clinical factors such as age, sex, history of heart disease, diabetes, hypertension, and prior stroke or thromboembolism. Each factor contributes to a total score, which helps estimate the risk of stroke and guide treatment decisions.

Key Features of the Calculator:

• User-friendly interface with checkboxes for each risk factor
• Real-time calculation of total CHA2DS2-VASc score
• Visual progress bar during calculation
• Options to copy or share results easily
• Mobile-responsive design for use on any device

Practical Example of Using the CHA2DS2-VASc Calculator

Scenario: A 68-year-old female patient has hypertension, diabetes, and a history of vascular disease.

Steps:

1. Check Hypertension, Diabetes Mellitus, Age 65–74 years, Vascular Disease, and Female Sex.
2. Click Calculate Score.
3. The calculator assigns points as follows:
   • Hypertension: 1
   • Diabetes Mellitus: 1
   • Age 65–74: 1
   • Vascular Disease: 1
   • Female Sex: 1
4. Total CHA2DS2-VASc Score = 5

A score of 5 indicates a moderate to high stroke risk, suggesting that the patient may benefit from anticoagulant therapy.
