Frequently Asked Questions
Common questions about ASCVD risk and cardiovascular prevention
What is a 10-year heart disease risk score?
A 10-year heart disease risk score estimates the chance of having a major cardiovascular event, such as heart attack or stroke, within the next 10 years. It uses factors like age, sex, blood pressure, cholesterol, smoking, diabetes, and treatment status.
Who should use a heart disease risk calculator?
Risk calculators are most useful for adults ages 40–79 who do not already have known cardiovascular disease. They can help guide prevention discussions with a healthcare provider, including whether lifestyle changes or cholesterol-lowering medication may be appropriate.
What risk level is considered high?
Many guidelines consider a 10-year ASCVD risk of 20% or higher to be high risk. A risk of 7.5% to 19.9% is often considered intermediate, and below 5% is generally low risk. Treatment decisions also depend on risk enhancers and clinical judgment.
Can I lower my cardiovascular risk?
Yes. Cardiovascular risk can often be reduced by controlling blood pressure, improving cholesterol, quitting smoking, managing diabetes, maintaining a healthy weight, eating a heart-healthy diet, exercising regularly, and taking medications when recommended.
Why does cholesterol matter for heart disease risk?
LDL cholesterol contributes to plaque buildup in arteries, which can narrow blood vessels and increase the risk of heart attack and stroke. HDL cholesterol helps transport cholesterol away from arteries, while triglycerides can reflect metabolic risk.
Is this calculator a diagnosis?
No. This tool provides an educational estimate based on the information entered. It should not replace professional medical advice, diagnosis, or treatment. Discuss results with a healthcare provider, especially if your score is intermediate or high.
