Know your 10-year risk of a heart attack or stroke in 2 minutes.
A clinical-grade estimate based on the 2013 ACC/AHA ASCVD Pooled Cohort Equations — the same math your doctor uses.
Your score is the estimated probability of a heart attack or stroke in the next 10 years. Doctors use these three bands to decide whether to recommend statins and other therapies.
Below the average for your age. Keep the habits that are working.
Diet, activity, recheck every 4–6 years.
On the edge. Family history, high LDL, or chronic inflammation tip the decision.
Discuss lifestyle and whether a statin makes sense.
A statin is likely to lower your risk meaningfully. Bring this to your doctor soon.
Statin plus BP, smoking, glucose control.
This calculator uses the ASCVD Pooled Cohort Equations published by the American College of Cardiology and American Heart Association in 2013 — the same math your primary care doctor's clinical decision support uses.
It combines your sex, age, race, cholesterol, blood pressure, and three yes/no factors into a single 10-year probability. Nothing you type is stored — the calculation runs in your browser.
Read the full methodologyThe ASCVD Pooled Cohort Equations were derived from five large U.S. cohort studies and are the current standard used in ACC/AHA prevention guidelines. They perform best in adults 40–79 without prior cardiovascular disease. Accuracy varies for people whose demographics were under-represented in the source cohorts.
The 2013 Pooled Cohort Equations remain the anchor of the 2019 ACC/AHA Primary Prevention guideline and are used across U.S. clinical decision support. Newer models such as PREVENT (2023) exist and are being adopted alongside; we plan to add a PREVENT calculator once its guidance is fully settled.
No. This tool estimates PRIMARY prevention risk. If you've already had a heart attack, stroke, stent, or coronary bypass, your care plan should be built around secondary-prevention guidance, not this score.
Nothing about your health inputs is sent to a server. The calculation runs entirely in your browser. We use a privacy-first analytics setup that records only the page you're on — no cookies, no cross-site tracking.
The Pooled Cohort Equations were not derived on people outside 40–79, so the estimate isn't reliable there. Under 40, your 10-year risk is almost always low even with risk factors — the more useful conversation is lifetime risk. Over 79, a physician should weigh the score against your overall health.
