ASCVD Risk Score Calculator

The ASCVD Risk Score Calculator estimates your 10-year risk of atherosclerotic cardiovascular disease using key factors like age, cholesterol, and blood pressure. This tool helps adults aged 40-79 without existing heart disease understand their cardiovascular health to guide preventive care. Whether you are considering statin therapy, checking your lifestyle impact, or planning long-term health goals, this calculator provides a clear, personalized risk assessment.

Enter your age in years (40-79 years)
Enter your total cholesterol in mg/dL
Enter your HDL ("good") cholesterol in mg/dL
Enter your systolic blood pressure (top number) in mmHg
Are you currently taking medication for high blood pressure?
Have you been diagnosed with diabetes?
Are you a current smoker?

How 10-Year ASCVD Risk Is Calculated

The 10-Year ASCVD Risk represents the probability of having a heart attack or stroke within the next decade. This tool uses the Pooled Cohort Equations developed by the American Heart Association and American College of Cardiology to ensure clinical accuracy.

First, the calculator analyzes your inputs, such as age and cholesterol levels, assigning specific weight to each risk factor. Then, it applies these values to a baseline survival curve specific to your gender and race. This process highlights how controllable factors, like blood pressure and smoking, significantly influence your overall heart health compared to fixed factors like age.

10-Year ASCVD Risk = 1 - Baseline Survival ^ (exp(Sum of β-coefficients - Mean Sum of β-coefficients))

Where:

  • Beta (β) coefficients are the weighted values for risk factors based on large research studies.
  • Baseline Survival is the average survival rate for your specific gender and race group.

What Your 10-Year ASCVD Risk Means

This percentage represents the likelihood that you will experience a cardiovascular event, such as a heart attack or stroke, in the next ten years. Understanding your score allows you to take proactive steps to lower your risk and improve your longevity.

Low Risk (<5%) indicates a healthy profile, so you should focus on maintaining heart-healthy habits like a balanced diet and regular exercise. Borderline Risk (5% to 7.5%) suggests you should discuss risk-reduction strategies with your doctor. Intermediate Risk (7.5% to 20%) often warrants a conversation about whether statin therapy is right for you. High Risk (>20%) usually requires immediate medical intervention and aggressive lifestyle changes to prevent a cardiac event.

Important: This tool is intended for primary prevention only and should not be used if you already have a history of heart disease or stroke.

Reassess your risk every 4 to 6 years or whenever your health metrics change significantly.
