How Old Is Your Heart, Really? New Study Reveals It May Be Years Ahead of You



Most adults have aging hearts—and don’t even know it. But there’s good news: You can turn back the clock.


Your Heart Might Be Older Than You Think

You might feel fine, but your heart could be aging faster than the rest of your body—and new research shows this is more common than most people realize.

A large-scale study analyzing data from over 14,000 U.S. adults found that the average heart age in Americans is significantly older than their actual age. Women’s hearts were, on average, 4 years older, while men’s hearts showed an even greater gap—nearly 7 years older than their chronological age.

And the disparity gets wider for certain groups:

  • 1 in 3 men with a high school education or less had a heart age 10+ years older than their real age.

  • 1 in 5 women in similar circumstances showed the same pattern.


What Is “Heart Age,” and Why Does It Matter?

The researchers used the PREVENT Risk Age Equations, a new tool developed by the American Heart Association, to calculate each participant’s “heart age.” Unlike traditional cardiovascular risk scores that express your odds of developing heart disease as a percentage, this method tells you how old your heart actually functions. It's a more intuitive way to grasp your risk.

The takeaway? A heart that’s aging faster than you are means higher risk for cardiovascular events—even if you feel healthy.


What’s Driving the Fast-Forward Button on Your Heart?

The study pinpointed several key factors that accelerate heart aging:

  • High blood pressure

  • Poor cholesterol levels

  • Smoking

  • Diabetes

  • Declining kidney function

These are largely lifestyle-related and modifiable—meaning you can take steps to slow (or even reverse) the process.


How to Rewind Your Heart Age

If your heart’s aging ahead of schedule, it’s not too late to change the trajectory. Here are science-backed ways to start rejuvenating your cardiovascular health:

  • Lower blood pressure through stress management, reducing sodium, and staying active
  • Improve cholesterol with healthy fats, regular exercise, and fiber-rich foods
  • Balance blood sugar by prioritizing protein, increasing fiber, getting enough sleep, and strength training
  • Quit smoking—or get help to quit if needed
  • Consult your doctor about medications, supplements, or further screenings


Want to Know Your Own Heart Age?

You can try the PREVENT Risk Age Calculator—the same tool used in the study—to see where your heart stands and what you can do about it. It’s free and available to the public.


The Bottom Line:
Your heart may be aging faster than your birth certificate says—but you're not powerless. With the right lifestyle changes, it's possible to slow down or even reverse that clock.
