Enter patient details like age, cholesterol levels, blood pressure, and lifestyle factors to calculate your 10-year ASCVD (cardiovascular disease) risk. The Risk Calculator compares your current risk against optimal risk and projects how specific therapies and lifestyle changes can reduce your cardiovascular risk score.

ASCVD stands for Atherosclerotic Cardiovascular Disease. It refers to conditions caused by plaque buildup in the artery walls, including heart attack, stroke, and peripheral artery disease. The 10-year ASCVD risk score estimates a patient's probability of experiencing a cardiovascular event within the next 10 years.
The 10-year ASCVD risk score is expressed as a percentage representing the likelihood of a heart attack or stroke within 10 years. A score below 5% is considered low risk, 5–7.5% is borderline, 7.5–20% is intermediate, and above 20% is high risk. Clinicians use this score to guide treatment decisions.
Optimal ASCVD risk is the theoretical risk score for a patient of the same age, sex, and race who has ideal cardiovascular health — including non-smoking status, no diabetes, untreated normal blood pressure, and optimal cholesterol levels. Comparing your current risk to the optimal baseline helps identify how much room there is for improvement.
Treatment goals for ASCVD risk reduction typically target modifiable risk factors: LDL cholesterol reduction via statin therapy, blood pressure control, smoking cessation, and diabetes management. High-intensity statins can reduce LDL by roughly 50%, which corresponds to a significant reduction in 10-year cardiovascular risk. Your clinician will tailor goals based on your individual risk profile.
This calculator is based on the Pooled Cohort Equations (PCE) developed by the American College of Cardiology (ACC) and American Heart Association (AHA) in 2013. The equations were derived from several large population cohort studies and are validated for White and African American adults aged 40–79. Results for other racial groups should be interpreted with caution.
This calculator is designed for adults aged 40 to 79 without pre-existing cardiovascular disease. It is intended as a clinical decision support tool to assist healthcare providers in discussing cardiovascular risk and therapy options with patients. It should not replace professional medical advice.
Statin therapy reduces LDL cholesterol and consequently lowers cardiovascular event risk. Low-intensity statins reduce LDL by less than 30%, moderate-intensity by 30–49%, and high-intensity by 50% or more. This calculator projects the estimated 10-year risk reduction associated with each statin intensity level based on your baseline inputs.
US units express cholesterol in milligrams per deciliter (mg/dL), which is the standard in the United States. SI units express cholesterol in millimoles per liter (mmol/L), used in many other countries. To convert from mmol/L to mg/dL, multiply by 38.67 for cholesterol values. The calculator supports both unit systems for convenience.
