Estimate Your 10-Year CVD Risk
Enter your clinical and lifestyle details below. This tool gives an educational estimate of your 10-year cardiovascular disease risk.
What this cardiovascular disease risk calculator does
Cardiovascular disease (CVD) includes heart attack, stroke, and other blood vessel conditions. This calculator estimates your 10-year risk by combining major risk drivers: age, blood pressure, cholesterol profile, smoking status, diabetes status, body mass index, and family history.
Instead of looking at just one number (like cholesterol alone), this approach gives a broader picture of your overall risk. That makes it easier to prioritize the habits and treatment decisions that can create the biggest long-term benefit.
How to interpret your result
- Low risk: less than 5%
- Borderline risk: 5.0% to 7.4%
- Intermediate risk: 7.5% to 19.9%
- High risk: 20% or greater
If your estimate is intermediate or high, it does not mean a cardiac event is guaranteed. It means your prevention plan should be discussed with a clinician sooner rather than later.
Inputs explained
Age and sex
These are baseline contributors to CVD risk. Risk generally rises with age, and biological sex can influence baseline event rates.
Systolic blood pressure and treatment status
Systolic blood pressure (the top number) is a key predictor of heart and vascular strain. Whether blood pressure is treated or untreated changes risk interpretation.
Total cholesterol and HDL cholesterol
Total cholesterol reflects overall circulating cholesterol. HDL (“good” cholesterol) is often protective. Lower HDL combined with higher total cholesterol generally increases risk.
Smoking and diabetes
Smoking and diabetes are strong risk multipliers. If either is present, absolute risk can climb substantially, even when other values are near normal.
BMI and family history
BMI gives a quick body composition estimate, while family history captures inherited susceptibility and shared environmental factors.
How to lower cardiovascular risk over time
1) Control blood pressure
- Reduce sodium and ultra-processed foods.
- Aim for regular aerobic exercise (walking, cycling, swimming).
- Take prescribed medications consistently if indicated.
2) Improve lipid profile
- Increase soluble fiber (oats, beans, lentils).
- Swap saturated fats for unsaturated fats (olive oil, nuts, fish).
- Follow lipid testing intervals recommended by your clinician.
3) Stop smoking
Smoking cessation provides one of the fastest risk reductions. Combining behavioral support with nicotine replacement or other therapies can increase quit success.
4) Optimize blood sugar
If you have diabetes or prediabetes, coordinated management of A1c, blood pressure, and lipids can dramatically reduce long-term cardiovascular events.
5) Build sustainable lifestyle habits
- 150+ minutes/week of moderate activity
- 7-9 hours of sleep most nights
- Stress management and social connection
- Consistent follow-up with preventive care
Important limitations
This tool is a practical estimate and not a diagnosis. It does not include every possible variable (for example, chronic kidney disease, inflammatory disease, medications, ethnicity-specific calibration, or imaging findings such as coronary calcium score).
Always review important results with a licensed healthcare professional, especially if your estimate is elevated or if you have symptoms like chest pain, unexplained shortness of breath, or neurologic symptoms.
