How to Use This Calculator

1

Enter Your Lab Values

Input your age, sex, total cholesterol, and HDL from a recent lipid panel (within 1–2 years). If you don't have these, contact your doctor for a lipid panel order.

2

Add Clinical Status

Indicate your systolic blood pressure (the top number), whether you take BP medication, whether you currently smoke, and whether you have been diagnosed with diabetes.

3

Explore Your Results

See your 10-year CVD risk, heart age, and how you compare to peers. Switch to Factor Analysis and Improvement Planner tabs to understand drivers and personalized action steps.

Formula & Methodology

ATP III Framingham Point System (Grundy et al. 2002)

Total Points = Age pts + Cholesterol pts + HDL pts + BP pts + Smoking pts + Diabetes pts

Each risk factor contributes sex-specific, age-adjusted points. The total point score maps to a 10-year probability of coronary heart disease events via validated lookup tables from the Framingham Heart Study. Heart age is derived by binary-search: finding the age at which an optimally-profiled person of the same sex would match your actual risk score.

Key Terms

Framingham Risk Score
A sex-specific algorithm developed from the Framingham Heart Study predicting 10-year risk of coronary heart disease events (heart attack, CHD death) using six clinical variables.
Heart Age (Vascular Age)
The age at which an average, optimally-healthy person of your sex would have the same 10-year CVD risk as you. If your heart age exceeds your calendar age, your arteries are aging faster than expected.
HDL Cholesterol
High-density lipoprotein — the "good" cholesterol that removes harmful LDL from arteries. HDL ≥60 mg/dL is protective and earns a -1 point in the Framingham model. Low HDL (<40 mg/dL) is a major independent risk factor.
Systolic Blood Pressure
The top number in a blood pressure reading, reflecting the pressure when the heart beats. Elevated systolic BP (≥130 mmHg) is a major CVD risk driver, especially when untreated.
Risk Stratification
Categorizing patients as Low (<5%), Borderline (5–7.5%), Intermediate (7.5–20%), or High (≥20%) 10-year CVD risk to guide prevention and treatment decisions.
ASCVD vs CHD Risk
CHD (coronary heart disease) risk includes heart attacks and CHD death — what Framingham estimates. ASCVD (atherosclerotic CVD) additionally includes stroke, used in the newer 2013 Pooled Cohort Equations preferred by current US guidelines.

Real-World Examples

Example 1

Low Risk — Healthy 45-year-old woman

Female, 45, TC 185 mg/dL, HDL 62 mg/dL, SBP 118 mmHg, no treatment, non-smoker, no diabetes

Result: ~1% 10-year risk. Low category. Heart age ~38 years. Recommendation: maintain healthy lifestyle, recheck in 5 years.

Example 2

High Risk — 60-year-old male smoker

Male, 60, TC 260 mg/dL, HDL 35 mg/dL, SBP 150 mmHg, on BP treatment, current smoker, no diabetes

Result: ~25% 10-year risk. High category. Heart age 79+. Immediate smoking cessation, statin therapy, BP optimization, and cardiology referral recommended.

Understanding Cardiovascular Risk

Why the Framingham Score Matters

Cardiovascular disease (CVD) is the leading cause of death globally, responsible for approximately 17.9 million deaths per year. The Framingham Heart Study, launched in 1948, transformed our understanding of CVD by identifying modifiable risk factors through long-term population surveillance. The ATP III Framingham Risk Score, published in 2002, translates these decades of data into a practical clinical tool that predicts your 10-year probability of a heart attack or coronary death.

How Heart Age Changes Your Perspective

Telling a 50-year-old patient they have a 15% 10-year CVD risk is abstract. Telling them their heart is aging at the rate of a 65-year-old creates a visceral understanding that motivates change. Research shows that communicating vascular age alongside percentage risk improves patient understanding, intention to change behavior, and actual risk factor modification over time.

Limitations and Complementary Tools

The Framingham ATP III model was derived from a predominantly white, middle-class Massachusetts population in the 1970s–90s and may over- or underestimate risk in other racial and ethnic groups. It does not include family history of premature CVD, inflammatory markers (hs-CRP), coronary artery calcium (CAC) score, or ankle-brachial index — all of which can refine risk assessment in borderline cases. The 2013 ACC/AHA Pooled Cohort Equations are preferred for primary prevention decisions in US clinical practice but Framingham remains widely used internationally.

The Power of Combined Risk Factor Reduction

Individual risk factor modifications produce compounding benefits. Quitting smoking reduces CVD risk by ~50% within one year. Every 10 mmHg reduction in systolic blood pressure reduces major CVD events by ~20%. Statin therapy that lowers LDL by 40 mg/dL reduces CVD events by 25–35%. When combined in a patient with multiple risk factors, these interventions can move someone from the high-risk to intermediate or even low-risk category — translating to years of extended healthy life.

Frequently Asked Questions

The Framingham Risk Score is a sex-specific algorithm developed from the Framingham Heart Study that estimates your 10-year risk of cardiovascular disease events such as heart attack. It uses six clinical variables to calculate a point score that maps to a risk percentage using validated lookup tables.
Heart age (vascular age) is the age at which an optimally healthy person of your sex would have the same Framingham risk as you. It's calculated by binary-searching for the age where an "ideal" profile (TC=170, HDL=55/60, SBP=115, no treatment, no smoking, no diabetes) matches your actual risk. A heart age above your calendar age signals accelerated vascular aging.
No. Framingham ATP III estimates 10-year coronary heart disease (CHD) risk. The 2013 ACC/AHA Pooled Cohort Equations estimate broader 10-year ASCVD risk including stroke. Current US guidelines prefer PCE for clinical decision-making, but Framingham remains widely used internationally and gives comparable estimates.
Every 4–6 years in adults without CVD who are not on lipid-lowering therapy. More frequently (annually) if you have borderline risk, are monitoring lifestyle changes, or have started or changed medications affecting cholesterol or blood pressure.
Smoking cessation is typically most impactful (−4 to −9 points, −50% CVD risk within 1 year). Blood pressure control and statin therapy (lowering TC 20–40 mg/dL) are next. Combined, these interventions can shift a patient from high to intermediate or intermediate to low risk.
HDL removes harmful cholesterol from arteries and is inversely associated with CVD risk. The Framingham model awards −1 point for HDL ≥60 mg/dL. Regular aerobic exercise and avoiding smoking are the most effective ways to raise HDL.
The Framingham model was derived from a predominantly white population and may over- or underestimate risk in other groups. For non-white patients, the 2013 ACC/AHA Pooled Cohort Equations were developed in more diverse populations and are generally preferred.
In the Framingham model, treated patients score higher at the same systolic BP compared to untreated — reflecting that treated patients who still have elevated BP have greater underlying vascular damage. Optimal BP control (systolic <130 mmHg) substantially reduces risk regardless of treatment status.
