What it calculates

The “CHA₂DS₂-VASc (ext.)” calculator computes CHA₂DS₂-VASc score, points from 7 parameters: age (years), female (1 = yes), heart failure (1 = yes), hypertension (1 = yes), diabetes mellitus (1 = yes), prior stroke, tia or thromboembolism (1 = yes), vascular disease: prior mi, peripheral artery disease, aortic plaque (1 = yes).

Used by professionals and patients to assess health metrics, dosages, and risks.

Example calculation

With parameters Age = 72 years, Female (1 = yes) = 1, Heart failure (1 = yes) = 0, Hypertension (1 = yes) = 1, Diabetes mellitus (1 = yes) = 0, Prior stroke, TIA or thromboembolism (1 = yes) = 0, Vascular disease: prior MI, peripheral artery disease, aortic plaque (1 = yes) = 0 the result is 3 (Female sex is a risk modifier only when other risk factors are present).

FAQ

How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
