# HeartRiskCalc

> HeartRiskCalc is an independent, free educational website with browser-based cardiovascular risk calculators and source-linked heart health guides at https://heartattackriskcalc.com.

All calculators are free and require no account. Health inputs and calculated results stay in the browser. The site is not affiliated with AHA, ACC, MESA, or the Framingham Heart Study and is not physician-reviewed. It does not diagnose symptoms or prescribe treatment. For suspected heart attack symptoms, call emergency services (911 in the U.S.) immediately.

The home calculator uses 2013 PCE, not PREVENT. Separate pages implement PREVENT, MESA, and Framingham heart age. These models predict different outcomes; their percentages and thresholds are not interchangeable.
