About This Tool

The Heart Disease Risk Calculator estimates your 10-year risk of developing cardiovascular disease (CVD) — including heart attack, stroke, and related conditions — using the Framingham Risk Score, one of the most widely validated clinical risk models.

This tool considers key factors: age, sex, total cholesterol, HDL cholesterol, systolic blood pressure, blood pressure treatment status, smoking, and diabetes. These are the same factors your doctor evaluates during a cardiovascular risk assessment.

For a more complete picture of your cardiovascular health, also check your blood pressure risk category, track your resting heart rate fitness score, or evaluate your body fat percentage.

Frequently Asked Questions (FAQ)

What is the Framingham Risk Score?
The Framingham Risk Score is a validated clinical tool developed from the Framingham Heart Study that estimates the 10-year risk of developing cardiovascular disease. It considers age, sex, total cholesterol, HDL cholesterol, systolic blood pressure, blood pressure treatment status, smoking, and diabetes to produce a percentage risk score.
How accurate is this heart disease risk calculator?
This calculator uses a simplified version of the Framingham Risk Score model, which has been validated in large population studies. While it provides a useful estimate, it does not replace a clinical assessment. Factors like family history, diet, exercise habits, and biomarkers (e.g., CRP, lipoprotein(a)) are not included. Always discuss your results with a healthcare provider. You can also check your blood pressure risk for additional cardiovascular insights.
What does my 10-year heart disease risk percentage mean?
Your risk percentage estimates the likelihood of experiencing a cardiovascular event (heart attack, stroke, or cardiovascular death) within the next 10 years. For example, a 15% risk means that out of 100 people with similar risk profiles, about 15 would experience a cardiovascular event in 10 years. Low risk is below 5%, borderline is 5–9%, intermediate is 10–19%, and high risk is 20% or above.
What is "heart age" and why does it matter?
Heart age is an estimate of the age of a person with optimal risk factors who has the same cardiovascular risk as you. If your heart age is higher than your actual age, it means your risk factors are making your cardiovascular system age faster. This concept helps motivate lifestyle changes — reducing your heart age by managing risk factors can significantly lower your chance of heart disease.
How can I lower my heart disease risk?
The most impactful steps include: quitting smoking (reduces risk by up to 50% within 1–2 years), lowering LDL cholesterol through diet and/or statins, controlling blood pressure below 130/80 mmHg, managing diabetes effectively, exercising regularly (150+ minutes/week), eating a heart-healthy diet (Mediterranean or DASH), and maintaining a healthy weight.

Is my data private when using this calculator?
Yes, absolutely. All calculations happen entirely in your browser. No health data is sent to any server or stored externally. Your privacy is fully protected.
Who should use this heart disease risk calculator?
This tool is designed for adults aged 20–79 without a prior diagnosis of cardiovascular disease. It is most accurate for individuals who have not already had a heart attack, stroke, or other cardiovascular event. If you already have heart disease, your doctor will use different tools to manage your ongoing risk.
