AHA PREVENT Algorithm Replaces 30-Year Framingham Risk Score
The American Heart Association's new PREVENT algorithm is a major update to cardiovascular risk assessment, replacing the decades-old Framingham Risk Score. PREVENT accounts for kidney function, A1C, and social determinants of health for more accurate risk prediction across diverse populations.
Ready to run the numbers?
Why: Heart disease is the #1 killer in the US. The new PREVENT algorithm provides a more accurate risk assessment than older tools, especially for women, younger adults, and diverse populations. Knowing your risk score empowers preventive action.
How: We implement the AHA PREVENT equations using your age, blood pressure, cholesterol, BMI, eGFR, A1C, smoking status, and medication use. The algorithm calculates your 10-year and 30-year risk of atherosclerotic cardiovascular events.

CalculateWhat is the PREVENT 30-Year Heart Risk Model?
The AHA PREVENT model estimates 30-year cardiovascular disease risk for adults 30-59โdifferent from traditional 10-year Framingham/ASCVD calculators. Risk categories: Low <10%, Borderline 10-20%, Intermediate 20-40%, High >40%. Modifiable risk shows potential from lifestyle changes.
What Are the Key Takeaways?
- โข The PREVENT model estimates 30-year CVD risk for adults 30-59 โ different from traditional 10-year Framingham/ASCVD calculators.
- โข Risk categories: Low <10%, Borderline 10-20%, Intermediate 20-40%, High >40%.
- โข Modifiable risk = current risk minus optimal risk โ shows potential from lifestyle changes.
- โข Quitting smoking, losing weight, and statins can each reduce risk significantly.
๐ก Did You Know?
๐ฌ How the PREVENT Model Works
The AHA PREVENT (Predicting Risk of cardiovascular disease EVents) model uses age, sex, blood pressure, cholesterol, BMI, diabetes, smoking, medications, and kidney function to estimate 30-year risk. It is designed for adults 30-59 and complements traditional 10-year calculators.
Risk Factors
- โข Age: Base risk ~5% at 30, increases ~1.5% per year
- โข Sex: Males have ~1.3ร higher risk
- โข BP: Each 10 mmHg above 120 adds ~3%
- โข Cholesterol: Each 20 mg/dL above 200 adds ~2% (reduced if on statins)
- โข HDL: Each 10 below 60 reduces risk 2%
- โข BMI: Each 5 units above 25 adds ~4%
- โข Diabetes +15%, Smoking +12%, Family history +5%, Reduced eGFR +8%
What Are the Expert Tips for Heart Health?
Quit Smoking
Smoking adds ~12% to 30-year risk. Quitting can reduce risk significantly.
Manage BP & Cholesterol
Medications and lifestyle changes can lower both. Discuss with your doctor.
Healthy Weight
BMI >25 adds risk. Aim for BMI 18.5-25 through diet and exercise.

Frequently Asked Questions
What is the PREVENT model?
The AHA PREVENT model estimates 30-year cardiovascular disease risk for adults 30-59. It uses age, sex, BP, cholesterol, BMI, diabetes, smoking, medications, and kidney function.
How is PREVENT different from 10-year risk calculators?
Traditional calculators (ASCVD, Framingham) estimate 10-year risk. PREVENT estimates 30-year risk, which is more relevant for younger adults who may have low 10-year but high lifetime risk.
What is modifiable risk?
Modifiable risk = your current risk minus your risk if all modifiable factors (BP, cholesterol, BMI, smoking) were optimized. It shows potential reduction from lifestyle and medication changes.
Should I take statins based on this calculator?
This calculator is for education only. Statin decisions should be made with your doctor based on your full medical history and guidelines.
What if my eGFR is reduced?
Reduced kidney function (eGFR <60) adds ~8% to 30-year risk. Use our Kidney Health Score calculator to estimate eGFR.
