Short, five minute treadmill test can predict the mortality risk same as the maximal fitness test that was earlier a reliable method in predicting the risks of premature deaths, finds a scientist Louise de Lannoy of Queen's University. The risk does not include other traditional risk factors like age, blood pressure, smoking status, diabetes, cholesterol, and family history. The study is published in the journal Mayo Clinic Proceedings.
Overwhelming evidence has shown a maximal fitness test is a reliable way to determine the risk of mortality. This established test, performed on a treadmill where the maximum incline is steadily increased until the participant cannot continue, isn't commonly used in clinical settings as it's time-intensive and uncomfortable for the patient.
Ms. de Lannoy's findings show a shorter treadmill test, called a submaximal fitness test, predicts the risk of premature death similarly to the maximal test. This is an important finding as it provides the clinician with options for assessing the health and risk of their patient.
To determine the results, the research team used data from a large study of 6,106 men and women, followed from 1974-2002 to look at change in submaximal test performance over time and its relationship to risk of premature death.
