Meet the free heart attack risk calculator doctors recommend
The PREVENT Online Calculator, introduced by the American Heart Association, is quickly becoming the go-to resource for doctors and patients alike. “It offers a more comprehensive assessment” than older tools, says interventional cardiologist Matthew Schoenfeld, MD, at Hackensack Meridian Jersey Shore University Medical Center.
What makes the PREVENT calculator so powerful?
Unlike older tools that only estimate heart attack risk, the PREVENT calculator has added capabilities, says Dr. Schoenfeld:
Woman's World Answers
- It includes kidney and metabolic health measures
- It includes heart failure (when the heart grows too weak to pump blood efficiently)
- It accounts for social determinants of health
- It works for a wider age range of users, from 30 to 79 years old
- It estimates your 10- and 30-year risk of total cardiovascular disease
How accurate is it—and should you trust it?
Heart attack risk calculators are not magic crystal balls that can see perfectly into the future. “Be aware, they are not diagnostic,” Dr. Schoenfeld advises. But this one provides a realistic estimate based on data from 6.5 million U.S. adults. And it delivers that insight from just a few basic health numbers you can enter in minutes. To get the most out of the technology, Dr. Schoenfeld advises users to be “as accurate as possible with their numbers.”
“This calculator can be used in conjunction with diagnostic testing to further assess your risk,” explains Dr. Schoenfeld. “Results should always be evaluated with consultation with your physician, as the value of each is greater when looking at the entire picture of your health.”
Who should (and shouldn’t) use a heart attack risk calculator
The PREVENT risk calculator is intended for adults ages 30 to 79. You should not use this tool if you already have an established diagnosis of cardiovascular disease, a coronary artery calcium score of 300+, positive genetic testing for inherited cardiovascular conditions or end-stage kidney disease, says Kyla Lara-Breitinger, MD, MS, a cardiologist and echocardiographer at the Mayo Clinic.
How to use the PREVENT calculator in minutes
To get started, gather a few basic health numbers (see below). Then visit the PREVENT website and click on “online calculator.” Next, input your health data and hit “calculate.” That’s it—your personalized risk assessment appears instantly.
The calculator will ask for these details:
- Your age (must be 30 to 79)
- Total cholesterol and HDL cholesterol
- Systolic blood pressure (the top number)
- eGFR (kidney function from a basic blood test)
- BMI (body mass index)
- Whether you have diabetes
- Whether you currently smoke
- Whether you take cholesterol or blood pressure medication
Dr. Lara-Breitinger explains you can personalize your results further by inputting additional information such as A1C and zip code.
The 3 heart issues this tool focuses on
This calculator estimates risk for three main heart problems: CVD (cardiovascular disease), ASCVD (atherosclerotic cardiovascular disease) and heart failure.
To better understand those distinctions, the American Heart Association explains them this way: Think of CVD as all heart and vessel disease, ASCVD as artery plaque disease and heart failure as a faulty pump for the heart.
The biggest benefits of knowing your heart disease risk early
You gain the power to take action before problems start. “This tool provides a categorical risk estimate to help you and your physician determine next steps of management,” explains Dr. Lara-Breitinger, co-author of Mayo Clinic Guide to a Happy, Healthy Heart. Armed with this information, you can make targeted changes that truly protect your heart.
“What people are concerned about is how they prevent a heart attack from ever happening,” explains Dr. Lara-Breitinger. She likes that this calculator helps point to things you can control to lower your risk.
10 simple ways to lower your heart attack risk now
Some risk factors—like age and genetics—can’t be changed. But you can improve the following factors:
- Eat a healthy diet
- Get exercise (reduce a sedentary lifestyle)
- Control blood sugar levels
- Lower blood pressure
- Improve cholesterol levels
- Reduce inflammation in the body
- Maintain a healthy weight/body composition
- Get quality sleep
- Reduce stress
- Avoid tobacco use
When using a heart attack risk calculator can backfire
For most people, knowing their risk is empowering. But technology-based wellness tools can trigger stress in a small group of people, research shows. For example, some people’s insomnia worsens by ruminating about their sleep-tracker scores. So if seeing the results of a heart attack risk calculator would be triggering for you—boosting heart-harming stress in the process—feel free to skip this tool.
It’s also important to remember that no calculator captures every possible risk factor that could come into play in a lifetime. “It is important to discuss any additional risks you may have with your healthcare professional,” Dr. Lara-Breitinger recommends.
This 2-minute check can protect your future
Experts recommend using a heart attack risk calculator once a year to gauge your personal health status. Think of it as an annual checkup you can do from home. The payoff: By making dietary and lifestyle changes, you can see your results improve over time!
