Your ‘Estimated Age’ From a Stress Test Is a Better Predictor of How Long You’ll Live Than Your Actual Age




How old does your birth certificate say you are? How old do you feel? The best predictor of how long you’ll live? It’s actually a stress test’s ‘estimated age.’

Cleveland Clinic researchers have developed a tool to calculate a person’s physiological age based on their exercise performance

What they examined
Researchers studied 126,356 patients who were referred for exercise treadmill testing at Cleveland Clinic between Jan. 1, 1991, and Feb. 27, 2015. They evaluated whether a patient’s estimated age based on their exercise performance is a better predictor of mortality than their chronological age.

The average age of study participants was 53.5 years old and 59 percent were male.

This new tool is a better predictor of lifespan
The study found that the estimated age based on exercise performance was better in predicting survival than the patients’ actual age. This held true for both men and women. Among those included, 55 percent of males and 57 percent of females between the ages of 50 and 60 years had an estimated age younger than their chronological age.

Why this new research is important
The study further confirmed that all exercise variables included in estimating physiological age were powerful predictors of survival, including exercise capacity, chronotropic competence (heart rate response to exercise) and heart rate recovery.

“Physiological age based on your exercise performance on stress testing is an even better predictor on how long you will live,” says cardiologist and study’s first author
