What is heart age and why is mine older than my real age?

Heart age is one of the cleverest ideas in preventive cardiology, because it takes an abstract risk percentage and turns it into a number that actually lands emotionally. It's defined as the age of a person with all-ideal risk factors who would have the same cardiovascular risk as you do right now.

So if you're 45 but your heart age comes back as 57, it means your current risk profile looks like that of a typical healthy 57-year-old. That gap is almost always driven by modifiable things — elevated blood pressure, high LDL cholesterol, smoking, or excess central weight — not by anything permanent.

The reason it's such a useful number is the same reason it can sting: it's concrete and it's personal. But the best part is that it runs in reverse. Because it's built from modifiable risk factors, improving them pulls your heart age back down — and watching that number fall month over month is far more motivating than watching a scale.

Calqulate.net's free Heart Age Calculator gives you the number, and the Heart Age Tracker (part of Calqulate Vitals) shows it dropping as your blood pressure, cholesterol, and habits improve.
