Now Cleveland Clinic researchers have developed a formula for calculating a person's physiological age based on how well they perform on an exercise stress test
. They found it's a more accurate predictor of how long a person will live than his or her calendar age.
There are a few different types of stress tests; the most common type is an exercise stress test
. This test is often done in your doctor's office, usually on a treadmill or stationary bicycle.
The study included 126,356 patients referred to the Cleveland Clinic between 1991 and 2015 for their first exercise stress test
, a common examination for diagnosing heart problems.
At the beginning and after a cycle of trainings, each patient underwent exercise stress test
(EST) and was scored on their ATT and AAL based on the Psychological Effects of Rehabilitation Score Scale (PERSS) according to Tylka and Makowska .
In addition to being an established tool for diagnosis and prognosis of coronary artery disease (CAD), exercise stress test
also provide vital information about cardiovascular physiology including blood pressure and heart rate (HR) responses.
All Patients Underwent an Exercise Stress Test
(TMT) and Echocardiographic Evaluation
Additionally, the center's non-invasive cardiac care diagnostics services cover 24-hour blood pressure monitoring; coronary catheterization; EKG-ECG; external event recording; stent follow-up; 24-hour Holter monitoring; Dobutamine Stress echocardiography; Ex-ECG (TMT); congestive heart failure diagnosis & management, complete executive physicals; exercise stress test
, cholesterol treatment, Ankle Brachial Index, Carotid & peripheral Doppler.
"Being unfit on a treadmill or in an exercise stress test
has a worse prognosis, as far as death, than being hypertensive, being diabetic or being a current smoker," said Wael Jaber, a cardiologist at the Cleveland Clinic, US and senior author of the study.

However, pharmacological stress testing usually is used only when an exercise stress test
can't be performed due to exercise-limiting problems, such as musculoskeletal problems or poor lung function, and in instances when the resting electrocardiogram (ECG) has certain baseline abnormalities or is considered to be non-diagnostic.
This assessment provides an estimate of a patient's METs that is assumed to correspond to a formal quantitative measurement of METs performed during a cardiac exercise stress test
The patient underwent an exercise stress test
using the Bruce protocol and was able to complete stage 1 with exercise for three minutes at a speed of 1.7 mph and a 10% incline.
