How old is your birth certificate? How old are you? The best predictor of how long will you live? This is actually the "estimated age" of the stress tests.

Researchers at Cleveland Clinic have developed a tool to calculate a person's physiological age based on their physical performance during a stress test. They found it to be a better predictor of the length of their lives relative to their actual age.
What they looked at
The researchers studied 126,356 patients who were referred for exercise mat tests at the Cleveland Clinic between January 1, 1991 and February 27, 2015. They badessed whether the patient's estimated age on the The basis of his physical performance was a better predictor of mortality than his chronological age. .
The average age of the participants in the study was 53.5 years and 59% were men. The document was published in European Journal of Preventive Cardiology.
This new tool is a better predictor of life expectancy
The study found that estimated age based on physical performance better predicted survival than the actual age of patients. This is true for men and women. Of these, 55% of men and 57% of women aged 50 to 60 had an estimated age below their chronological age.
The physiological age estimation formula was developed from the exercise variables collected during the patient stress test.
Why is this new research important?
The study also confirmed that all exercise variables included in the physiological age estimate were powerful predictors of survival, including exercise ability, proficiency chronotropic (heart rate response to exercise) and heart rate recovery.
"The physiological age based on your physical performance during stress testing is a better predictor of your life span," says the cardiologist and lead author of the study, Serge Harb, MD.
The key message to remember for patients is to do more exercise – and for health care providers to use this physiological age as a way to motivate their patients to improve their physical performance. For the first time, we can quantify the impact of your performance level on a treadmill test by adding or subtracting years from your current age.
According to the CDC, heart disease is the leading cause of death among women and men in the United States. The stress test is a common diagnostic tool for cardiovascular disease.
It is important to note that the study badyzed the results of a large population. You should always consult your health care provider before starting an exercise program.
