# Framingham Cardiovascular Risk Calculator

Estimate your 10-year risk of cardiovascular disease using the Framingham Risk Score. Factors in age, cholesterol, blood pressure, smoking, and diabetes.

## What this calculates

Estimate your 10-year risk of developing cardiovascular disease using the Framingham Risk Score. This validated tool uses your age, cholesterol levels, blood pressure, and other risk factors to predict your likelihood of a heart attack or stroke in the next decade.

## Inputs

- **Age** (years) — min 20, max 79 — Valid for ages 20-79
- **Sex** — options: Male, Female
- **Total Cholesterol** (mg/dL) — min 100, max 400 — Total cholesterol level from blood test
- **HDL Cholesterol** (mg/dL) — min 10, max 150 — HDL (good) cholesterol level
- **Systolic Blood Pressure** (mmHg) — min 80, max 250 — The top number of your blood pressure reading
- **Blood Pressure Being Treated** — Are you currently taking blood pressure medication?
- **Current Smoker** — Have you smoked in the past month?
- **Diabetic** — Have you been diagnosed with diabetes?

## Outputs

- **10-Year CVD Risk** — Estimated 10-year risk of cardiovascular event
- **Risk Category** — formatted as text — Classification of your cardiovascular risk level
- **General Recommendation** — formatted as text — Lifestyle and medical guidance based on risk level

## Details

The Framingham Risk Score was developed from the Framingham Heart Study, a landmark longitudinal study that began in 1948 in Framingham, Massachusetts. It remains one of the most widely used cardiovascular risk prediction tools in clinical medicine. The score estimates the probability of developing coronary heart disease, stroke, peripheral arterial disease, or heart failure within the next 10 years.

The major risk factors included are age, sex, total cholesterol, HDL cholesterol, systolic blood pressure (and whether it is being treated), smoking status, and diabetes. Each factor contributes points based on validated risk coefficients. The resulting percentage helps guide clinical decisions about preventive interventions, particularly statin therapy and blood pressure management.

IMPORTANT DISCLAIMER: This calculator is for educational purposes only. It provides a simplified estimation and should not replace comprehensive cardiovascular assessment by a healthcare provider. The Framingham score was primarily validated in white populations and may over- or under-estimate risk in other populations. Additional factors such as family history, inflammation markers, and coronary artery calcium scores may provide additional risk information.

## Frequently Asked Questions

**Q: What does a 10-year risk of 15% mean?**

A: A 10-year risk of 15% means that out of 100 people with your same risk profile, approximately 15 would be expected to experience a cardiovascular event (heart attack, stroke, or related condition) within the next 10 years. This does not mean you will definitely have an event; it is a statistical probability. Importantly, many of these risk factors are modifiable, meaning lifestyle changes and medical treatment can lower your actual risk below this estimate.

**Q: At what risk level should I consider statin therapy?**

A: Current American College of Cardiology/American Heart Association guidelines generally recommend discussing statin therapy for primary prevention when the 10-year risk is 7.5% or higher (using the newer ASCVD calculator) or 20% or higher using Framingham. For moderate risk (10-20%), the decision is shared between patient and physician based on additional factors. Statin therapy is more strongly recommended when risk exceeds 20% and lifestyle modifications alone have not adequately controlled cholesterol levels.

**Q: Why does the score give different point values by sex?**

A: Men and women have fundamentally different cardiovascular risk profiles. Men develop heart disease on average 10 years earlier than women, partly due to the protective effects of estrogen before menopause. The point systems are calibrated separately for each sex to reflect these biological differences. After menopause, women's cardiovascular risk accelerates, which is why the age points increase more steeply for women in older age groups.

**Q: What are the limitations of the Framingham Risk Score?**

A: The Framingham score was developed and validated primarily in white American populations and may overestimate risk in some populations (Japanese, Hispanic) and underestimate it in others (South Asian, African American). It does not account for family history of premature cardiovascular disease, inflammatory markers (CRP), coronary artery calcium, socioeconomic factors, or physical activity level. The newer ASCVD Pooled Cohort Equations address some of these limitations by including race-specific risk coefficients.
