American Heart Association ASCVD 10-Year Risk Calculator
Understanding Your ASCVD Risk
Atherosclerotic Cardiovascular Disease (ASCVD) refers to a buildup of plaque in the arteries, which can lead to serious conditions like heart attack and stroke. The American Heart Association (AHA) and American College of Cardiology (ACC) developed the Pooled Cohort Equations to estimate a person's 10-year risk of developing ASCVD.
This calculator provides an *illustrative* estimate of your 10-year ASCVD risk based on common risk factors. It is designed to help you understand the impact of various factors on your heart health. This tool is NOT a substitute for professional medical advice, diagnosis, or treatment. Always consult with a qualified healthcare provider for personalized medical guidance.
Key Risk Factors Included:
- Age: Risk generally increases with age.
- Sex: Men typically have a higher risk than women at younger ages.
- Race: African Americans have different risk profiles compared to other groups.
- Total Cholesterol & HDL Cholesterol: High total cholesterol and low "good" HDL cholesterol increase risk.
- Systolic Blood Pressure: High blood pressure puts strain on your arteries.
- Blood Pressure Medication: Indicates managed hypertension, which is a risk factor.
- Smoking Status: Smoking significantly damages blood vessels and increases risk.
- Diabetes: Diabetes is a major risk factor for heart disease.
Preventive Measures:
Regardless of your calculated risk, adopting a heart-healthy lifestyle is crucial for everyone:
- Healthy Diet: Focus on fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit saturated and trans fats, sodium, and added sugars.
- Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity exercise per week.
- Maintain a Healthy Weight: Losing even a small amount of weight can significantly improve heart health.
- Quit Smoking: If you smoke, quitting is the single most impactful step you can take for your heart.
- Manage Blood Pressure and Cholesterol: Work with your doctor to keep these levels within healthy ranges, often through lifestyle changes and sometimes medication.
- Manage Diabetes: If you have diabetes, strict management of blood sugar levels is vital.
- Regular Check-ups: Discuss your risk factors and preventive strategies with your healthcare provider regularly.
