MEDICAL DISCLAIMER

Medical disclaimer

Last updated: 2026-09-03

If this may be a medical emergency, call 911.

Do not use HeartRiskCalc to decide whether you are having a heart attack right now. Symptoms are not the same as risk. If you have chest pressure, unexplained shortness of breath, a cold sweat, or any of the warning signs described on our Signs of a Heart Attack page, call emergency services.

What HeartRiskCalc is

An educational tool that estimates the population-level probability of a first heart attack or stroke over 10 years, using the 2013 ACC/AHA ASCVD Pooled Cohort Equations. The result is a statistical estimate, not a diagnosis. It is not personalized medical advice.

What HeartRiskCalc is not

It is not a substitute for a physician who knows your history.
It cannot detect an ongoing heart attack, arrhythmia, valve disease, or any condition that requires an ECG, imaging, or a physical exam.
It is not validated for people with pre-existing cardiovascular disease. If you've had a heart attack, stroke, stent, or coronary bypass, your care plan should be built around secondary-prevention guidance.
It is not validated for adults under 40 or over 79.

Talk to a professional

Always seek the advice of your physician or other qualified health provider with any questions you have about a medical condition. Never disregard professional medical advice or delay seeking it because of something you read on HeartRiskCalc.
