Heart Disease Risk Calculator

Measure risk with inputs and transparent weighted scoring. Compare contributors across habits and health markers. Use results wisely with prevention habits and medical guidance.

Enter your health inputs

The calculator estimates a weighted risk index from common cardiovascular contributors. Results are educational and should support, not replace, medical judgment.

Example data table

Active Adult 34 118 176 63 23.8 No 5 8% Low

Formula used

The calculator uses an educational weighted composite model built from common cardiovascular risk contributors. Each input receives positive or negative points, then the total is converted to a percentage-style risk index.

Composite Score = Age + Sex + Systolic BP + Total Cholesterol + HDL + BMI + Resting Heart Rate + Exercise + Smoking + Diabetes + Family History + BP Medication

Risk Index (%) = (Composite Score ÷ 80) × 100

Estimated Heart Age = Actual Age + ((Risk Index − 20) ÷ 4)

Higher blood pressure, cholesterol, smoking, diabetes, obesity, inactivity, and family history add risk points. Better HDL, stronger activity patterns, and lower resting heart rate can reduce points.

This method is designed for screening and education. It is not identical to formal clinical tools such as ASCVD or Framingham calculators.

How to use this calculator

  1. Enter your age and select sex.
  2. Provide systolic blood pressure, total cholesterol, and HDL values from recent readings or lab work.
  3. Enter BMI, resting heart rate, and average exercise days per week.
  4. Choose whether you currently smoke, have diabetes, use blood pressure medication, or have a family history.
  5. Click Calculate Risk to show results above the form.
  6. Use the category, top drivers, and action notes to identify which modifiable factors deserve attention first.

Frequently asked questions

1. Is this calculator a medical diagnosis?

No. It is an educational risk estimate based on common contributors. It cannot confirm disease, blocked arteries, or emergency conditions.

2. Which blood pressure value should I enter?

Enter your systolic pressure, the top number. Use an average of recent reliable readings instead of one unusual measurement.

3. Why does HDL lower the score?

Higher HDL is generally linked with a more favorable cardiovascular profile. In this model, stronger HDL reduces points and slightly improves the result.

4. Does exercise really affect the result much?

Yes. Regular activity can improve blood pressure, weight, heart rate, insulin sensitivity, and lipid patterns. The calculator rewards consistent weekly movement.

5. What does estimated heart age mean?

It compares your current pattern with a simplified risk benchmark. A heart age above your actual age suggests more accumulated risk factors.

6. Can younger people still score high?

Yes. Smoking, diabetes, obesity, high blood pressure, poor lipids, and inactivity can still push the score upward, even at younger ages.

7. When should I see a doctor?

See a clinician if your result is high, symptoms are present, or your lab values and blood pressure are worsening. Chest pain needs urgent care.

8. Can I download my results?

Yes. After calculation, use the CSV button for data export or the PDF button for a report-style snapshot of the results section.
