What is heart age?
Heart age is the estimated age of your cardiovascular system based on your risk factor profile. If your heart age is younger than your actual age, your cardiovascular health is above average for your demographic. If it's older, you have more risk factors than the average person your age — and a greater chance of heart attack or stroke in the next 10 years.
The concept is widely used by the CDC, NHS (UK), and American Heart Association as a public health communication tool because research shows people respond more actionably to a "heart age" framing than to abstract percentage risk numbers.
Key risk factors explained
| Factor | Ideal Value | Impact on Heart Age |
|---|---|---|
| Systolic BP | <120 mmHg | Each 20 mmHg increase ≈ +2–4 heart years |
| Total Cholesterol | <200 mg/dL | High TC significantly raises 10-yr risk |
| HDL (good) Cholesterol | >60 mg/dL | High HDL is protective — lowers heart age |
| Smoking | Non-smoker | Adds approximately 5–8 years to heart age |
| Diabetes | No diagnosis | Adds approximately 4–6 years to heart age |
| BP Medication | — | Treated hypertension adjusted in model |
FAQ
Yes — several risk factors are modifiable. Quitting smoking reduces heart age by 5–8 years within a few years of cessation. Reducing systolic blood pressure by 20 mmHg via medication or lifestyle changes reduces estimated 10-year CVD risk by roughly 25–30%. Regular aerobic exercise (150 min/week) improves HDL, reduces resting BP, and improves insulin sensitivity. Dietary changes affecting cholesterol can show measurable results within 3–6 months.
The Framingham Heart Study found that biological sex is a significant predictor of cardiovascular risk. Premenopausal women have natural cardioprotective effects from estrogen. For any given risk factor profile, men typically carry higher cardiovascular risk than women of the same age until around menopause, after which women's risk accelerates. The model uses sex-specific scoring coefficients to account for this.
