Learn how the American Heart Association PREVENT™ equations estimate cardiovascular risk—and access the official AHA calculator.
The American Heart Association PREVENT™ equations estimate the risk of developing cardiovascular disease using information about cardiovascular, kidney and metabolic health, including cholesterol, blood pressure, kidney function, body mass index, diabetes and smoking status.
PREVENT can estimate 10-year cardiovascular risk for eligible adults ages 30–79 and 30-year risk for eligible adults ages 30–59 who do not have known cardiovascular disease. The results can support informed conversations about prevention but are not a diagnosis or a substitute for medical care.
The PREVENT™ calculator is provided by the American Heart Association. It will open on the AHA website, where you can enter your health information and receive an estimated 10-year and, when applicable, 30-year cardiovascular risk.
You will need recent cholesterol, blood pressure, body mass index and kidney-function results, along with information about smoking, diabetes and certain medications.
Don’t have all of these numbers? EMC Wellness’s Cardiometabolic Risk Screening includes the necessary laboratory testing and measurements, an eligible PREVENT™ calculation, and a personalized written explanation of your results.
The PREVENT™ calculator is developed and maintained by the American Heart Association and is not hosted by EMC Wellness.
Your estimated percentage represents the likelihood that a person with similar risk factors will experience a cardiovascular event during the specified time period. PREVENT can estimate combined cardiovascular disease risk as well as risks related to atherosclerotic cardiovascular disease and heart failure.
Risk estimates are most useful when considered alongside your health history, family history, laboratory results and personal goals. A low short-term estimate does not necessarily mean that every cardiovascular risk factor is optimal—particularly for younger adults whose longer-term risk may be more informative.
PREVENT provides a broad estimate using established cardiovascular, kidney and metabolic risk factors, but it does not capture every influence on cardiovascular health.
Factors such as family history, physical fitness and advanced biomarkers—including Lipoprotein(a), ApoB and ApoA-1—may provide additional information that is not reflected in the standard risk estimate. PREVENT should therefore be viewed as one part of a more complete cardiovascular assessment.

Advanced lipid testing can provide a more detailed look at cardiovascular risk factors not fully captured by a standard cholesterol panel or risk calculator. EMC Wellness offers self-pay testing with advanced biomarkers and personalized interpretation to help you understand your overall risk.

PREVENT™ is designed for adults ages 30–79 who do not have established cardiovascular disease. Ten-year estimates are available for eligible adults ages 30–79, while 30-year estimates are available for eligible adults ages 30–59. It should not be used as a diagnosis or substitute for medical care.
You will need basic health information including your age, sex, blood pressure, total cholesterol, HDL cholesterol, kidney function (eGFR), body mass index (BMI), smoking status, diabetes status, and whether you take medications for blood pressure or cholesterol.
Not necessarily. PREVENT™ is a useful estimate of overall cardiovascular risk, but it does not include every potential risk factor. Family history and biomarkers such as Lp(a), ApoB, and hs-CRP may provide additional information for some people. Your results should be considered in the context of your individual health history.
